Ecologists grapple with complex, changing situations. Historians, sociologists and philosophers studying the construction of science likewise attempt to account for (or discount) a wide variety of influences making up the scientists' "ecologies of knowledge." This paper introduces a graphic methodology, mapping, designed to assist researchers at both levels-in science and in science studies-to work with the complexity of their material. By analyzing the implications and limitations of mapping, I aim to contribute to an ecological approach to the philosophy of (...) science. (shrink)

Ecological research and conservation practice frequently raise difficult and varied ethical questions for scientific investigators and managers, including duties to public welfare, nonhuman individuals (i.e., animals and plants), populations, and ecosystems. The field of environmental ethics has contributed much to the understanding of general duties and values to nature, but it has not developed the resources to address the diverse and often unique practical concerns of ecological researchers and managers in the field, lab, and conservation facility. The emerging field of (...) “ecological ethics” is a practical or scientific ethics that offers a superior approach to the ethical dilemmas of the ecologist and conservation manager. Even though ecological ethics necessarily draws from the principles and commitments of mainstream environmental ethics, it is normatively pluralistic, including as well the frameworks of animal, research, and professional ethics. It is also methodologically pragmatic, focused on the practical problems of researchers and managers and informed by these problems in turn. The ecological ethics model offers environmental scientists and practitioners a useful analytical tool for identifying, clarifying, and harmonizing values and positions in challenging ecological research and management situations. Just as bioethics provides a critical intellectual and problem-solving service to the biomedical community, ecological ethics can help inform and improve ethical decision making in the ecology and conservation communities.

Conservation biologists and other environmentalists confront five obstacles in building support for regulatory policies that seek to exclude or remove introduced plants and other non-native species that threaten to harm natural areas or the natural environment. First, the concept of “harm to the natural environment” is nebulous and undefined. Second, ecologists cannot predict how introduced species will behave in natural ecosystems. If biologists cannot define “harm” or predict the behavior of introduced species, they must target all non-native species as (...) potentially “harmful”. an impossibly large regulatory task. Third, loss of species richness may constitute harm to an environment, but introduced organisms typically, generally, and significantly add to species richness in ecosystems. If species richness correlates with desirable ecosystem properties, moreover, such as stability and productivity, as some ecologists believe, then introduced organisms, by increasing species richness, would support those desirable properties. Fourth, one may plausibly argue that extinction constitutes environmental harm, but there is no evidence that non-native species, especially plants, are significant causes of extinction, except for predators in certain lakes and other small island-like environments. Fifth, while aesthetic, ethical, and spiritual values may provide a legitimate basis for invasive species policy, biologists often cite concepts such as “biodiversity” and ecosystem “health” or “integrity” to provide a scientific justification. To assert that non-native species threaten biodiversity or undermine ecosystem health, however, may be to draw conceptual entailments or consequences from definitions of “biodiversity” and “integrity” that arbitrarily exclude non-native species or make the presence of exotic species a per se indicator of decline.

The philosophy of ecology addresses foundational conceptual and methodological issues in ecological science. Specifying these issues is complicated by the fact that there is disagreement among ecologists over how to identify the proper domain of ecology. Many ecologists prefer a more restrictive definition that focuses on properties of nonhuman organisms in natural environments. Others defend a more expansive definition that includes the study of human-environment relations, a view that challenges the traditional conception of ecology as strictly a natural (...) biological science. Consequently, one's understanding of the philosophy of ecology will depend in part on whether one endorses a more restrictive or more expansive conception of ecology. This article reviews issues in the philosophy of ecology in both its restrictive and expansive modes. In its restrictive mode, the philosophy of ecology addresses conceptual and methodological issues in population, community and ecosystem ecology. In its expansive mode, the philosophy of ecology also addresses foundational issues in the human ecological sciences, such as ecological economics and ecological psychology. In this expansive mode the line between ecology-the-science and ecology-the-philosophicalworldview becomes increasingly blurred, but a commitment to scientific methodology prevents ecology from becoming a mere mouthpiece for speculative or radical ecological philosophies.

Philosophers of the life sciences have devoted considerably more attention to evolutionary theory and genetics than to the various sub-disciplines of ecology, but recent work in the philosophy of ecology suggests reflects a growing interest in this area (Cooper 2003; Ginzburg and Colyvan 2004). However, philosophers of biology and ecology have focused almost entirely on conceptual and methodological issues in population and community ecology; conspicuously absent are foundational investigations in ecosystem ecology. This situation is regrettable. Ecosystem concepts play a central (...) role in many branches of theoretical and applied ecology, and in environmental literature generally. Indeed, for some historians, the division of ecological theory into population-community and ecosystem research traditions, and the methodological and conceptual debates that have arisen between workers in these respective camps, is the distinguishing feature of 20th century ecological science (Hagen 1992). These include debates over, among others: reductionistic vs. holistic research methodologies; the existence and metaphysics of ecological “kinds”; the relationship between evolutionary mechanisms and ecosystem phenomena; and the nature and scope of ecological science and its relationship to other branches of natural and social science. Philosophers of ecology have written on all these topics, but almost exclusively from the theoretical perspective of population, community or evolutionary ecology. Philosophical attention to these issues from the perspective of ecosystem ecology is long overdue. It would be misleading to assert that philosophers in general have ignored ecosystem ecology. Environmental philosophers, including environmental ethicists so-called “radical” environmental philosophers (deep ecologists, social ecologists, ecofeminists, etc.), and policy theorists, have had a long-standing interest in ecosystem ecology (e.g. Callicott 1986; Cahen 1988; Warren and Cheney 1993; Westra 1994; Sagoff 1997; Fitzsimmons 1999)..

The subject of Western environmental ethics has been widely written about and discussed but the same can not be said of 'Japanese' environmental ethics. This discipline has not been covered in any branch of Japanese philosophy nor has there been sufficient pressure exerted by ecologists on Japanese thinkers and writers to explain how the Japanese code addresses environmental concerns. Although some Japanese scholars have in the past articulated their ideas on working with the natural world, the field covering the (...) spirit and core of Japanese environmental ethics remains largely unexplored. This paper examines and compares the discipline of Japanese environmental ethics, a 'bottom up process', with that of the Western model, a 'top down process'. It defines, and presents a new insight into environmental ethics from the Japanese perspective where the concept of 'living with nature' is more sensitive towards the environment than is the Western one of 'taming nature'.

Ecologists and environmental theorists have paid little attention to our direct, sensory experience of the enveloping world. In this paper I discuss the importance of such experience for ecological philosophy. Merleau-Ponty’s careful phenomenology of perceptual experience shows perception to be an inherently creative, participatory activity-a sort of conversation, carried on underneath our spoken discourse, between the living body and its world. His later work discloses the character of language itself as a medium born of the body’s participation with a (...) world experienced as alive. That living world is none other than the Earth.

The demise of behaviorism has made ethologists more willing to ascribe mental states to animals. However, a methodology that can avoid the charge of excessive anthropomorphism is needed. We describe a series of experiments that could help determine whether the behavior of nonhuman animals towards dead conspecifics is concept mediated. These experiments form the basis of a general point. The behavior of some animals is clearly guided by complex mental processes. The techniques developed by comparative psychologists and behavioral ecologists (...) are able to provide us with the tools to critically evaluate hypotheses concerning the continuity between human minds and animal minds.

To explore the potential evolutionary relevance of heritable epigenetic variation, the National Evolutionary Synthesis Center recently hosted a catalysis meeting that brought together molecular epigeneticists, experimental evolutionary ecologists, and theoretical population and quantitative geneticists working across a wide variety of systems. The group discussed the methods available to investigate epigenetic variation and epigenetic inheritance, and how to evaluate their importance for phenotypic evolution. We found that understanding the relevance of epigenetic effects in phe- notypic evolution will require clearly delineating (...) epigenetics within existing terminology and expanding research efforts into ecologically relevant circumstances across model and nonmodel organisms. In addition, a critical component of understanding epigenetics will be the development of new and current statistical approaches and expansion of quantitative and population genetic theory. Although the importance of heritable epigenetic effects on evolution is still under discussion, investigating them in the context of a multidisciplinary approach could transform the field. (shrink)

I. Introduction. Throughout the history of ecology, there have been many different views held about the nature of ecological communities. Some ecologists have argued that they exist mind-independently with discrete boundaries and others have contended that they are merely ephemeral collections of species with minimal interactions. In this essay, first I provide an analysis of the concept of ecological community; or better yet, community concepts. Second, I consider the most serious challenge to the reality of ecological communities; what is (...) called gradient analysis pioneered by Robert Whittaker. I argue that many have misinterpreted the results of gradient analysis and that properly construed the existence of communities, and more specifically, community properties are not threatened. Finally, I sketch how the debate over the reality of communities matters to environmental policy. (shrink)

Ecologists attempt to understand the diversity of life with mathematical models. Often, mathematical models contain simplifying idealizations designed to cope with the blooming, buzzing confusion of the natural world. This strategy frequently issues in models whose predictions are inaccurate. Critics of theoretical ecology argue that only predictively accurate models are successful and contribute to the applied work of conservation biologists. Hence, they think that much of the mathematical work of ecologists is poor science. Against this view, I argue (...) that model building is successful even when models are predictively inaccurate for at least three reasons: models allow scientists to explore the possible behaviors of ecological systems; models give scientists simplified means by which they can investigate more complex systems by determining how the more complex system deviates from the simpler model; and models give scientists conceptual frameworks through which they can conduct experiments and fieldwork. Critics often mistake the purposes of model building, and once we recognize this, we can see their complaints are unjustified. Even though models in ecology are not always accurate in their assumptions and predictions, they still contribute to successful science. (shrink)

In this article we examine the specific contributions Native American thought can make to the ongoing search for a Western ecological consciousness. We begin with a review of the influence of Native American beliefs on the different branches of the modem environmental movement and some initial comparisons of Western and Native American ways of seeing. We then review Native American thought on the natural world, highlighting beliefs in the need for reciprocity and balance, the world as a living being, and (...) relationships with animals. We conclude that Native American ideas are important, can prove inspirational in the search for a modem environmental consciousness, and affirm the arguments of both deep ecologists and ecofeminists.

This article examines some of the main tenets of competition theory in light of the theory of evolution and the concept of an ecological niche. The principle of competitive exclusion and the related assumption that communities exist at competitive equilibrium - fundamental parts of many competition theories and models - may be violated if non-equilibrium conditions exist in natural communities or are incorporated into competition models. Furthermore, these two basic tenets of competition theory are not compatible with the theory of (...) evolution. Variation in ecologically significant environmental factors and non-equilibrium in population numbers should occur in most natural communities, and such changes have important effects on community relations, niche overlap, and the evolution of ecosystems. Ecologists should view competition as a process occurring within a complexdynamic system, and should be wary of theoretical positions built upon simple laboratory experiments or simplistic mathematical models.In considering the relationship between niche overlap and competition, niche overlap should not be taken as a sufficient condition for competition; many factors may prevent or diminish competition between populations with similar resource utilization patterns. The typically opposing forces of intraspecific and interspecific competition need to be simultaneously considered, for it is the balance between them that in large part determines niche boundaries.

We consider several ways in which a good understanding of modern techniques and principles in physics can elucidate ecology. We focus on analogical reasoning between these two branches of science. This style of reasoning requires an understanding of both sciences and an appreciation of the similarities and points of contact between the two. In the current ecological literature on the relationship between ecology and physics, there has been some misunderstanding about the nature of modern physics and its methods. Physics is (...) seen as being much cleaner and tidier than ecology. When ecology is compared to this idealised, fictional version of physics, ecology looks very different, and the prospect of ecology and physics learning from one another is questionable. We argue that physics, once properly appreciated, is more like ecology than ecologists have thus far appreciated. Physicists and ecologists can and do learn from each other, and in this paper we outline how analogical reasoning can facilitate such exchanges. (shrink)

Rationalism is the key to the connected oppressions of women and nature in the West. Deep ecology has failed to provide an adequate historical perspective or an adequate challenge to human/nature dualism. A relational account of self enables us to reject an instrumental view of nature and develop an alternative based on respect without denying that nature is distinct from the self. This shift of focus links feminist, environmentalist, and certain forms of socialist critiques. The critique of anthropocentrism is not (...) sacrificed, as deep ecologists argue, but enriched.

In this response, we clarify several misunderstandings of the understanding/acceptance principle and defend our specific operationalization of that principle. We reiterate the importance of addressing the problem of rational task construal and we elaborate the notion of computational limitations contained in our target article. Our concept of thinking dispositions as variable intentional-level styles of epistemic and behavioral regulation is explained, as is its relation to the rationality debate. Many of the suggestions of the commentators for elaborating two-process models are easily (...) integrated into our generic dual-process account. We further explicate how we view the relation between System 1 and System 2 and evolutionary and normative rationality. We clarify our attempt to fuse the contributions of the cognitive ecologists with the insights of the original heuristics and biases researchers. (shrink)

The question of whether there are laws in ecology is important for a number of reasons. If, as some have suggested, there are no ecological laws, this would seem to distinguish ecology from other branches of science, such as physics. It could also make a difference to the methodology of ecology. If there are no laws to be discovered, ecologists would seem to be in the business of merely supplying a suite of useful models. These models would need to (...) be assessed for their empirical adequacy but not for their ability to capture fundamental truths, or the like. If, on the other hand, ecology does have laws, this prompts further questions about what these laws are and why even the best candidates for ecological laws fall short of what might be expected of laws.

This essay examines mountaineering narratives in the light of recent eco-critical scholarship to assert that their tales of intense awareness and connection reveal a more fundamental integration between human subject and natural object than our culture has imagined. North American climbing narratives show three primary modes of imagining nature: first, as an object to conquer; second, as a picturesque setting to admire; third, as the extension of a self whose identity is shaped by the interpenetration of the human and the (...) natural. The third of these modes motivates my study because this interpretation offers a lived example of the type of human connection to the natural world philosophers theorize is possible, and ecologists insist is necessary.

There is a long history of controversy in ecology over the role of competition in determining patterns of distribution and abundance, and over the significance of the mathematical modeling of competitive interactions. This paper examines the controversy. Three kinds of considerations have been involved at one time or another during the history of this debate. There has been dispute about the kinds of regularities ecologists can expect to find, about the significance of evolutionary considerations for ecological inquiry, and about (...) the empirical credentials of theoretical studies of competition. Each of these elements is examined with an eye toward gaining philosophical clarification of the issues involved. In the process, certain shortcomings of contemporary philosophical theories are revealed. In particular, I argue that plausibility arguments based on background considerations are an important part of the model building tradition, but that current accounts of the structure and evaluation of scientific theories do little to illuminate this side of theoretical ecology.

I offer a feminist critique of deep ecology as presented in the seminal papers of Naess and Devall. I outline the fundamental premises involved and analyze their internal coherence. Not only are there problems on logical grounds, but the tacit methodological approach of the two papers are inconsistent with the deep ecologists’ own substantive comments. I discuss these shortcomings in terms of a broader feminist critique of patriarchal culture and point out some practical and theoretical contributions which eco-feminism can (...) make to a genuinely deep ecology problematic.

Since Kant, philosophy has been obsessed with epistemological questions pertaining to the relationship between mind and world and human access to objects. In The Democracy of Objects Bryant proposes that we break with this tradition and once again initiate the project of ontology as first philosophy. Drawing on the object-oriented ontology of Graham Harman, as well as the thought Roy Bhaskar, Gilles Deleuze, Niklas Luhman, Aristotle, Jacques Lacan, Bruno Latour and the developmental systems theorists, Bryant develops a realist ontology that (...) he calls “onticology”. This ontology argues that being is composed entirely of objects, properties, and relations such that subjects themselves are a variant of objects. By way of systems theory and cybernetics, Bryant argues that objects are dynamic systems that relate to the world under conditions of operational closure. In this way, he integrates the most vital discoveries of the anti-realists within a realist ontology that does justice to both the material and cultural. Onticology proposes a flat ontology where objects of all sorts and at different scales equally exist without being reducible to other objects and where there are no transcendent entities such as eternal essences outside of dynamic interactions among objects. This work will be of great interest to Continental philosophers, ecologists, cultural theorists, media theorists, and those following recent developments in the thought of speculative realists.

Since the inception of their subject as a distinct area of study in philosophy, environmental ethicists have quarreled over the choice of entities with which an environmental ethic should be concerned. A dichotomous ontology has arisen with the ethical atomists, e.g., Singer and Taylor, arguing for moral consideration of individual organisms and the holists, e.g., Rolston and Callicott, focussing on moral consideration of systems. This dichotomous view is ecologically misinformed and should be abandoned. In this paper, I argue that the (...) organization of the natural world, as viewed by some ecologists and evolutionary biologists, is structured on various levels that are not reducible to one another. This hierarchical view, expressed by Salthe and Eldredge, provides the most complete and accurate ontology for environmental ethics. (shrink)

In this paper I review some theoretical exchanges and empiricalresults from recent work on human behavior and cognition in thehope of indicating some productive avenues for critical engagement.I focus particular attention on methodological debates between Evolutionary Psychologists and behavioral ecologists. I argue for a broader and more encompassing approach to the evolutionarily based study of human behavior and cognition than either of these two rivals present.

A formal theory of the ecological niche is indispensable not only for semantic precision in philosophy to understand and compare it with other meanings of niche, but also when computer scientists and ecologists desire to create interoperable software where one can retrieve the niche of a species and compare their parameters. The proposed model is a more fine-grained description of the ecological niche, including the distinction between its complex concept, the abstract niche (‘fundamental niche’) with its hypervolume in multidimensional (...) space, and its realisations (‘realised niches’). The presented ecological niche may initiate new avenues for research in ecology, particularly concerning the conditions/categories of a hypervolume, as well as further philosophical inquiry and comparison with other niches.

Ecologists typically invoke "law-like" generalizations, ranging over "structural" and/or "functional" kinds, in order to explain generalizations about "historical" kinds (such as biological taxa)rather than vice versa. This practice is justified, since structural and functional kinds tend to correlate better with important ecological phenomena than do historical kinds. I support these contentions with three recent case studies. In one sense, therefore, ecology is, and should be, more nomothetic, or law-oriented, than idiographic, or historically oriented. This conclusion challenges several recent philosophical (...) claims about the nature of ecological science. (shrink)

A post-positivist understanding of ecological science and the call for an “ecological ethic” indicate the need for a radically new approach to evaluating environmental change. The positivist view of science cannot capture the essence of environmental sciences because the recent work of “reflexive” ecological modelers shows that this requires a reconceptualization of the way in which values and ecological models interact in scientific process. Reflexive modelers are ecological modelers who believe it is appropriate for ecologists to examine the motives (...) for their choices in developing models; this self-reflexive approach opens the door to a new way of integrating values into public discourse and to a more comprehensive approach to evaluating ecological change. This reflexive building of ecological models is introduced through the transformative simile of Aldo Leopold, which shows that learning to “think like a mountain” involves a shift in both ecological modeling and in values and responsibility. An adequate, interdisciplinary approach to ecological valuation, requires a re-framing of the evaluation questions in entirely new ways, i.e., a review of the current status of interdisciplinary value theory with respect to ecological values reveals that neither of the widely accepted theories of environmental value—neither economic utilitarianism nor intrinsic value theory (environmental ethics)—provides a foundation for an ecologically sensitive evaluation process. Thus, a new, ecologically sensitive, and more comprehensive approach to evaluating ecological change would include an examination of the metaphors that motivate the models used to describe environmental change.

James Woodward offers a conception of explanation and mechanism in terms of interventionist counterfactuals. Based on a case from ecology, I show that ecologists’ approach to that case satisfies Woodward’s conditions for explanation and mechanism, but his conception does not fully capture what ecologists view as explanatory. The new mechanistic philosophy likewise aims to describe central aspects of mechanisms, but I show that it is not sufficient to account for ecological mechanisms. I argue that in ecology explanation involves (...) identification of invariant and insensitive causal relationships and descriptions of the mechanistic characteristics that make these relations possible. †To contact the author, please write to: Department of Philosophy, University of Dayton, 300 College Park, Dayton, OH 45469‐1546; e‐mail: paslarvi@notes.udayton.edu.

The notion of a superorganism has had a long and not altogether respectable history (Ghiselin 1974). The idea of comparing the world to a divine animal goes back to a creation myth in Plato's dialogue Timaeus, and it has played an important role in occult metaphysics ever since. Astrology, for example, works by superimposing a diagram of the human body over a map of the celestial bodies. The analogy between organisms and societies has also played a major role in political (...) discourse.

Few areas of scientific investigation have spawned more alternative approaches than animal behavior: comparative psychology, ethology, behavioral ecology, sociobiology, behavioral endocrinology, behavioral neuroscience, neuroethology, behavioral genetics, cognitive ethology, developmental psychobiology—the list goes on. Add in the behavioral sciences focused on the human animal, and you can continue the list with ethnography, biological anthropology, political science, sociology, psychology (cognitive, social, developmental, evolutionary, etc.), and even that dismal science, economics. Clearly, no reasonable-length chapter can do justice to such a varied collection. We (...) have opted therefore to focus on three of these subdisciplines and to provide a somewhat historical tour of them, mentioning along the way the philosophical points that are of particular interest to us, but allowing the development of these points to be limited only by the imaginations of our readers. For readers seeking a more-traditional historical survey, see Dewsbury (1984a, b) and Burghardt (1985a). Our chosen brief is to write about comparative psychology, ethology, and cognitive ethology, although other approaches, especially neuroscience, will be mentioned where appropriate. These sciences are philosophically significant because they are enmeshed in ancient philosophical questions about the nature of mind and purposeful action and about the differences between humans and other animals. These sciences are also clustered because of their attention to mechanistic explanations of individual animal behavior as opposed to attempting to capture regularities at a population level, such as the game-theoretic strategic models popular among behavioral ecologists.

Fifty years after his death, the thought of the French scientist and Jesuit Pierre Teilhard de Chardin (1881–1955) continues to inspire new ways of understanding humanity’s future. Trained as a paleontologist and philosopher, Teilhard was an innovative synthesizer of science and religion, developing an idea of evolution as an unfolding of material and mental worlds into an integrated, holistic universe at what he called the Omega Point. His books, such as the bestselling The Phenomenon of Man, have influenced generations of (...) ecologists, environmentalists, planners, and others concerned with the fate of the earth.This book brings together original essays by leading experts who reflect on Teilhard’s legacy for today’s globalized world. They explore such topics as: the idea of God and the person; quantum reality and Teilhard’s vision; spiritual resources for the future; politics and economics; and a charter for co-evolution.

A reformulation of our understanding of freedom is required if we are adequately to confront the environmental crisis. Engaging the debate between biocentric ecologists and sociocentric ecologists, I argue that the biocentric effort to ascribe rights (negative liberty) to nature is misbegotten. In turn, I suggest that the sociocentric effort to seek ecological realignment through the extension of human reason (positive liberty) is equally problematic. Martin Heidegger, who rejects both “negative” and “positive” notions of liberty, offers an understanding (...) of human freedom that constitutes an ecologically attuned alternative. (shrink)

Biological diversity would apparently seem the most intuitive and easily studied of all the ecological concepts. However, in practice biodiversity has suffered from great number of definitions that vary with the specific needs of the different researchers, thus making it extremely confusing as an ecological concept. In this paper, I shortly review the concept of biodiversity showing that there exists a substantial ambiguity among ecologists as far as biodiversity conceptualization and evaluation is concerned. I conclude that, due to this (...) major disagreement on its very nature, biodiversity may be defined simply as a set of multivariate summary statistics for quantifying different characteristics of community structure.

Ecologists have proposed several incompatible definitions of ecological stability. Emulating physicists, mathematical ecologists commonly define it as Lyapunov stability. This formalizes the problematic concept by integrating it into a well‐developed mathematical theory. The formalization also seems to capture the intuition that ecological stability depends on how ecological systems respond to perturbation. Despite these advantages, this definition is flawed. Although Lyapunov stability adequately characterizes perturbation responses of many systems studied in physics, it does not for ecological systems. This failure (...) reveals a limitation of its underlying mathematical theory, and an important difference between dynamic systems modeling in physics and ecology. *Received March 2006; revised June 2008. †To contact the author, please write to: Philosophy Department, 151 Dodd Hall, Florida State University, Tallahassee, FL 32306; e‐mail: jjustus@fsu.edu.

This essay explores two strategies of inquiryin ecological science. Ecologists may regardthe sites they study either as contingentcollections of plants and animals, therelations of which are place-specific andidiosyncratic, or as structured systems andcommunites that are governed by general rules,forces, or principles. Ecologists who take thefirst approach rely on observation, induction,and experiment – a case-study or historicalmethod – to determine the causes of particularevents. Ecologists who take the secondapproach, seeking to explain by inferringevents from general patterns or principles,confront (...) four conceptual obstacles which thisessay describes. Theory in ecology must (1)define and classify the object it studies,e.g., the ecosystem, and thus determine theconditions under which it remains the ``same''system through time and change. Ecologistsmust (2) find ways to reject as well as tocreate mathematical models of the ecosystem,possibly by (3) identifying efficient causes ofecosystem organization or design. Finally,ecologists will (4) show ecological theory canhelp solve environmental problems both inpristine and in human-dominated systems. Afailure to solve – or even to address – theseobstacles suggests that theoretical ecology maybecome a formal science that studies themathematical consequences of assumptionswithout regard to the relation of theseassumptions to the world.

The sheer complexity of Spinoza's thinking makes it impossible for any movement to use him as a patron. But philosophically engaged ecologists and environmentalists may find in his system an inexhaustible source of inspiration. This holds good even if he was personally a ?speciesist? and uninterested in animals or landscapes. Underestimation of his potential help is due to a variety of factors: failure to pay enough attention to the structure of his system, belief in its close resemblance to that (...) of Hobbes, and interpretation of ?understanding love of God? as a contemplative, general attitude incompatible with environmentalist activism and interest in every living being. The system of Spinoza is compatible with activism ? like that of Jan de Witt ? and with respect for all things as ?expressions of the power of God or Nature? (shrink)

Technological advancement has an ambivalent character concerning the impact on biodiversity. It accounts for major detrimental environmental impacts and aggravates threads to biodiversity. On the other hand, from an application perspective of environmental science, there are technical advancements, which increase the potential of analysis, detection and monitoring of environmental changes and open a wider spectrum of sustainable use strategies.The concept of biodiversity emerged in the last two decades as a political issue to protect the structural and functional basis of (...) earthbound life. In this respect, it represents a great challenge for science, in particular for ecology, which is the scientific discipline mainly involved in contributing to understand biodiversity issues.In this paper, we state a strong necessity for ecologists to work in close connection with other disciplines and within their own discipline across the different organisation levels. Each level has some specific properties to which ecological terminology has been adapted, and joint views are necessary to understand complex networks. In this context, ecological theory provides the background to analyse biological complexity and the relationship of structure and dynamics on different integration levels and provides the interface to mediate social and political issues.Important features of new technologies for advances in ecological theory refer to (1) an increase in information processing capacities, (2) more efficient automatic data acquisition and device operation, and (3) an increase in resolution (grain and extent).One crucial consideration we analyse is the trend that a quantitative development in one particular discipline may open a new potential for qualitative advancement in other disciplines when the quantitative advancement is applied in a new disciplinary context.We illustrate these qualitative developments that are based on technological advancements and which helped to advance ecological theory qualitatively with two examples: (1) The underlying mechanisms causing regularly oscillating rodent populations are subject to a decade long discussion in ecology. Using the possibilities of modern information processing, it is possible to represent the discussed hypotheses in an integrative object oriented model and analyse how the underlying causal net works. (2) The second example originates from biosafety research dealing with the environmental impact of genetically modified organisms (GMO). The project GenEERA develops a complex up-scaling procedure from below field-level information to the landscape scale in order to investigate spread and persistence of GM oil seed rape (Brassica napus) under different scenarios. The approach gives an example, how ecological modelling can be used to combine different information levels to derive conclusions on a higher spatial scale.In an overall conclusion we relate the described approaches to a wider system analytical context in which we interpret theory developments and biodiversity issues with a system theoretical description of growth processes. We obtain the view that in self-organising systems there is a tendency for autonomous development which tends to be dominating far away from capacity limitations. However, while approaching capacity limitations, a tendency towards closer coupling of internal and external cause-effect networks emerges. We also find that the relation of biodiversity, ecosystem services, and social dynamics can be interpreted in this framework. In this context, the demand for closer interdisciplinary cooperation to solve existing problems appears as an indication of emerging capacity limitations (or the reaching of saturation levels) both, in the theoretical as well as in the (bio-) physical domain.

In this fresh and powerfully argued book, Mark Bernstein identifies the qualities that make an entity deserving of moral consideration. It is frequently assumed that only (normal) human beings count. Bernstein argues instead for "experientialism"--the view that having conscious experiences is necessary and sufficient for moral standing. He demonstrates that this position requires us to include many non-human animals in our moral realm, but not to the extent that many deep ecologists champion.

There has been a significant amount of uncertainty and controversy over the prospects for general knowledge in ecology. Environmental decision makers have begun to despair of ecology's capacity to provide anything more than case by case guidance for the shaping of environmental policy. Ecologists themselves have become suspicious of the pursuit of the kind of genuine nomothetic knowledge that appears to be the hallmark of other scientific domains. Finally, philosophers of biology have contributed to this retreat from generality by (...) suggesting that there really are no laws in biology. This paper addresses these issues by providing a framework for thinking about general knowledge claims in ecology. It introduces a philosophical taxonomy that classifies generalizations into three broad categories – phenomenological, causal and theoretical. It then turns to the difficult problem of laws, arguing that, while there are probably no laws as that term has been understood in philosophy of science, it doesn't follow that everything in ecology is equally contingent. A mechanism for recognizing degrees of contingency in ecological generalizations is developed. The paper concludes by examining the implications of the analysis for the controversies noted at the outset. (shrink)

Computer simulation has become important in ecological modeling, but there have been few assessments on how complex simulation models differ from more traditional analytic models. In Part I of this paper, I review the challenges faced in complex ecological modeling and how models have been used to gain theoretical purchase for understanding natural systems. I compare the use of traditional analytic simulation models and point how that the two methods require different kinds of practical engagement. I examine a case study (...) of three models from the insect resistance literature in transgenic crops to illustrate and explore differences in analytic and computer simulation models. I argue that analyzing simulation models has been often inappropriately managed with expectations derived from handling analytic models. In Part II, I look at simulation as a hermeneutic practice. I argue that simulation models are a practice or techné. I the explore five aspects of philosophical hermeneutics that may be useful in complex ecological simulation: (1) an openness to multiple perspectives allowing multiple levels of scientific pluralism, (2) the hermeneutic circle, a back and forth in active communication among both modelers and ecologists; (3) the recognition of human factors and the nature of human practices as such, including recognizing the role of judgments and choices in the modeling enterprise; (4) the importance of play in modeling; (5) the non-closed nature of hermeneutic engagement, continued dialogue, and recognizing the situatedness, incompleteness, and tentative nature of simulation models.

Historians of science generally consider that Darwinism has played an important part in the birth of scientific ecology. Now most 19th century seminal works of the new discipline have been elaborated within a Lamarckian framework. The source of this paradox lies in the double-content of the adaptation concept, considered as a static phenomenon by the ecologists and as a dynamic process by the evolutionists. Although closely related nowadays, as shown by modern evolutionary ecology, the problematics of the fields of (...) research at issue were initially separated. (shrink)

There are a number of different species concepts currently in use. The variety results from differing desiderata and practices of taxonomists, ecologists and evolutionary theorists. Recently, arguments have been presented for pluralism about species. I believe this is unsatisfactory, however, because of the central role of species in biological theory. Taking the line that species are individuals, I ask what might individuate them. In other work I have argued that dynamical systems are individuated by their cohesion. I present here (...) a version of a cohesion concept of species that accounts for the advantages of other species concepts, and is open-ended enough to accommodate additions to or changes in biological theory. On my account biological forces combine like Newtonian forces, to work on a common locus. Just as we might have an electromagnetic system, we might have an ecological species, if the dominant source of cohesion is ecology, but there is no certainty that biological species will divide up into elegant single principle types anymore than there is for physical systems.

Research in ecology and evolutionary biology (evo-eco) often tries to emulate the “hard” sciences such as physics and chemistry, but to many of its practitioners feels more like the “soft” sciences of psychology and sociology. I argue that this schizophrenic attitude is the result of lack of appreciation of the full consequences of the peculiarity of the evo-eco sciences as lying in between a-historical disciplines such as physics and completely historical ones as like paleontology. Furthermore, evo-eco researchers have gotten stuck (...) on mathematically appealing but philosophi- cally simplistic concepts such as null hypotheses and p-values defined according to the frequentist approach in statistics, with the consequence of having been unable to fully embrace the complexity and subtlety of the problems with which ecologists and evolutionary biologists deal with. I review and discuss some literature in ecology, philosophy of science and psychology to show that a more critical methodological attitude can be liberating for the evo-eco scientist and can lead to a more fecund and enjoyable practice of ecology and evolutionary biology. With this aim, I briefly cover concepts such as the method of multiple hypotheses, Bayesian analysis, and strong inference. (shrink)

Ecological feminism is a feminism which attempts to unite the demands of the women's movement with those of the ecological movement. Ecofeminists often appeal to "ecology" in support of their claims, particularly claims about the importance of feminism to environmentalism. What is missing from the literature is any sustained attempt to show respects in which ecological feminism and the science of ecology are engaged in complementary, mutually supportive projects. In this paper we attempt to do that by showing ten important (...) similarities which establish the need for and benefits of on-going dialogue between ecofeminists and ecosystem ecologists. (shrink)

Recent disclosures regarding the relationship between Heidegger’s thought and his own version of National Socialism have led me to rethink my earlier efforts to portray Heidegger as a forerunner of deep ecology. His political problems have provided ammunition for critics, such as Murray Bookchin, who regard deep ecology as a reactionary movement. In this essay, I argue that, despite some similarities, Heidegger’s thought and deep ecology are in many ways incompatible, in part because deep ecologists—in spite of their criticism (...) of the ecologically destructive character of technological modernity—generally support a “progressive” idea of human evolution. (shrink)

I discuss conceptual confusions shared by deep ecologists over such questions as gender, essentialism, normative dualism, and eco-centrism. I conclude that deep ecologists have failed to grasp both the epistemological challenge offered by ecofeminism and the practical labor involved in bringing about social change. While convergencies between deep ecology and ecofeminism promise to be fruitful, these are celebrated in false consciousness, unless remedial work is done.

Diagrams refer to the phenomena overtly represented, to analogous phenomena, and to previous pictures and their graphic conventions. The diagrams of ecologists Clarke, Hutchinson, and H.T. Odum reveal their search for physical analogies, building on the success of World War II science and the promise of cybernetics. H.T. Odum's energy circuit diagrams reveal also his aspirations for a universal and natural means of reducing complexity to guide the management of diverse ecological and social systems. Graphic conventions concerning framing and (...) translation of ecological processes onto the flat printed page facilitate Odum's ability to act as if ecological relations were decomposable into systems and could be managed by analysts external to the system.

Robert MacArthur's mathematical ecology is often regarded as ahistorical and has been criticized by historically oriented ecologists and philosophers for ignoring the importance of history. I clarify and defend his approach, especially his use of simple mathematical models to explain patterns in data and to generate predictions that stimulate empirical research. First I argue that it is misleading to call his approach ahistorical because it is not against historical explanation. Next I distinguish three kinds of criticism of his approach (...) and argue that his approach is compatible with the first two of them. Finally, I argue that the third kind of criticism, advanced by Kim Sterelny and Paul Griffiths, is largely irrelevant to MacArthur's approach. ‡I am especially grateful to Thomas Nickles for encouragement and helpful comments on earlier versions of this paper. Thanks also to Guy Hoelzer, Stephen Jenkins, and Jay Odenbaugh for comments on an earlier draft, Kim Sterelny for clarifications of the Tasmania example, Gregory Mikkelson for references, and the audience at PSA 2006 for discussions. †To contact the author, please write to: Department of History and Philosophy of Science, University of Pittsburgh, 1017 Cathedral of Learning, Pittsburgh, PA 15260; e-mail: yoi5@pitt.edu.

This article uses the interpretive work of Dreyfus, Gadamer, Nussbaum and Taylor to explore the natural environment as a shared ecological and social commonality. I focus on the supposition that the natural world possesses intrinsic value and new political structures are needed. I explore how we might better engage with multiple cultures concerning matters at the heart of ecological politics. Political interpretivists offer processes of equal facilitation and maximization that work to include environmental values in democratic thought. Interpretivists differ from (...) earth-based and neo-conservative environmentalists, who dominate modern debates. The differences involve understanding the role of practical reasoning and how humanity interacts with the natural world. Intriguingly, then, interpretivists concur with Deep Ecologists that nature possesses intrinsic value, but do so guided by an ideal of authenticity. (shrink)

Abstract Ecological communities around the world are under threat while a consensus theory of community structure remains elusive. In the last decade ecologists have struggled with two seemingly opposing theories: niche-based theory that explains diversity with species’ differences and the neutral theory of biodiversity that claims that much of the diversity we observe can be explained without explicitly invoking species’ differences. Although ecologists are increasingly attempting to reconcile these two theories, there is still much resistance against the neutral (...) theory of biodiversity. Here we argue that the dispute between the two theories is a classic example of the dichotomy between philosophical perspectives, realism and instrumentalism. Realism is associated with specific, small-scale and detailed explanations, whereas instrumentalism is linked to general, large-scale, but less precise accounts. Recognizing this will help ecologists get both niche-based and neutral theories in perspective as useful tools for understanding biodiversity patterns.

A core project for deep ecologists is the reformulation of the concept of self. In searching for a more inclusive understanding of self, deep ecologists often look to Buddhist philosophy, and to the Japanese Buddhist philosopher Dōgen in particular, for inspiration. I argue that, while Dōgen does share a nondualist, nonanthropocentric framework with deep ecology, his phenomenology of the self is fundamentally at odds with the expanded Self found in the deep ecology literature. I suggest, though I do (...) not fully argue for it, that Dōgen’s account of the self is more sympathetic to one version of ecofeminism than to deep ecology. (shrink)

Exclusively instrumental notions of rationality not only reinforce attitudes conducive to the destruction of the natural world, but also undermine attempts to construct environmental ethics that involve more harmonious relationships between humans and nature. Deep ecologists and other ecological critics of instrumental rationality generally prefer some kind of spiritual orientation to nature. In this paper I argue against both instrumental rationalists and ecological spiritualists in favor of a communicative rationality which encompasses the natural world. I draw upon both critical (...) theory and recent scientific intimations of agency in nature. (shrink)

To generate explanatory theory, ecologists must wrestle with how to represent the extremely many, diverse causes behind phenomena in their domain. Early twentieth-century plant ecologists Frederic E. Clements and Henry A. Gleason provide a textbook example of different approaches to explaining vegetation, with Clements allegedly committed, despite abundant exceptions, to a law of vegetation, and Gleason denying the law in favor of less organized phenomena. However, examining Clements's approach to explanation reveals him not to be expressing a law, (...) and instead to be developing an explanatory structure without laws, capable of progressively integrating causal complexity. Moreover, Clements and Gleason largely agree on the causes of vegetation; but, since causal understanding here underdetermines representation, they differ on how to integrate recognized causes into general theory---that is, in their methodologies. Observers of the case may have mistakenly assumed that scientific representation across the disciplines typically aims at laws like Newton's, and that representations always reveal scientists' metaphysical commitments. Ironically, in the present case, this assumption seems to have been made even by observers who regard Clements as naı¨ve for his alleged commitment to an ecological law. (shrink)

I argue that Nietzsche’s thinking, contrary to the interpretation of Martin Heidegger, is compatible with an ecologically oriented, environmentally concemed philosophizing. In support of this contention, I show that Nietzsche’s critique of traditional Western thinking closely parallels the critique of this tradition by environmentalist writers such as Lynn White, Ir. I also show that one of the principal thrusts of Nietzsche’s own philosophizing consists of the attempt to overcome the kind of thinking that has provided a theoretical foundation for the (...) technological control and exploitation of the natural world. Finally, I show that Nietzsche’s notion of the will to power, at least in several of its fonnulations, has certain affinities to the ecosystem approach of modem ecologists. (shrink)

(Total word count 2,647) I. Introduction. Given the work of Robert MacArthur and his followers, some skeptical ecologists charge that theoretical modeling building has gone evidentially unconstrained. That is, models are often constructed which resist empirical testing. In this essay, I argue that “bottle experiments” do provide model building with important evidential constraints using an example of chaos producing models that have been tested against the dynamics of flour beetle populations. Critics reply however that this and other bottle experiments (...) are importantly unlike and irrelevant to non-manipulated systems in nature. I provide two possible responses to this view. Finally, I provide a practical suggestion for how to move the debate forward. (shrink)

Ecologists may apply their science either to manage ecosystems to increase the long-run benefits nature offers man or to protect ecosystems from anthropogenie insults and injuries. Popular reasons for supposing that these two tasks (management and protection) are complementary turn out not to be supported by the evidence. Nevertheless, society recognizes the protection of the “health” and “integrity” of ecosystems to be an important ethical and cultural goal even if it cannot be backed in detail by utilitarian or prudential (...) arguments. It is a legitimate purpose of ecological science, moreover, to describe and help society preserve ecosystem “health” and “integrity,” insofar as these are considered as privative qualities. (shrink)

The shape of the Earth's surface, its topography, is a fundamental dimension of the environment, shaping or mediating many other environmental flows or functions. But there is a major divergence in the way that topography is conceptualized in different domains. Topographic cartographers, information scientists, geomorphologists and environmental modelers typically conceptualize topographic variability as a continuous field of elevations or as some discrete approximation to such a field. Pilots, explorers, anthropologists, ecologists, hikers, and archeologists, on the other hand, typically conceptualize (...) this same variability in terms of hills and valleys, mountains and plains, barrows and trenches, that is, as (special sorts of) objects, with locations, shapes, and often names of their own. In this chapter, we sketch an approach to bridging this fundamental gap in geographic information infrastructure. (shrink)

Words such as selfish and altruistic that describe conduct toward self and others are notoriously ambiguous in everyday language. I argue that the ambiguity is caused, in part, by the coexistence of multiple belief systems that use the same words in different ways. Each belief system is a relatively coherent linguistic entity that provides a guide for human behavior. It is therefore a functional entity with design features that dictate specific word meaning. Since different belief systems guide human behavior in (...) different directions, specific word meanings cannot be maintained across belief systems. Other sources of linguistic ambiguity include i) functional ambiguity that increases the effectiveness of a belief system, ii) ambiguity between belief systems that are functionally identical but historically distinct, and iii) active interference between belief systems. I illustrate these points with a natural history study of the word selfish and related words in everyday language. In general, language and the thought that it represents should be studied in the same way that ecologists study multi-species communities. (shrink)

The distinction between the context ofdiscovery and the context of justificationrestricts philosophy of science to the rationalreconstruction of theories, and characterizesscientific discovery as rare, theoreticalupheavals that defy rational reconstruction. Kuhnian challenges to the two contextsdistinction show that non-rational elementspersist in the justification of theories, butgo no further to provide a positive account ofdiscovery. A gradualist theory of discoverydeveloped in this paper shows, with supportfrom ecological cases, that discoveries areroutinely made in ecology by extending modelsto new domains, or by making additions (...) toearlier models. The logic of discovery isphilosophically accessible once it isappreciated that model truth is presumed, evenif counterfactually, in ecologists' applicationof models. A gradualist view shows thatmodels' heuristic power routinely leads todiscoveries. (shrink)

Ecology has often been characterized as an immature scientific discipline. This paper explores some of the sources of this alleged immaturity. I argue that the perception of immaturity results primarily from the fact that historically ecologists have based their work upon two very different approaches to research.

Explaining the persistence of populations is an important quest in ecology, and is a modern manifestation of the balance of nature metaphor. Increasingly, however, ecologists see populations (and ecological systems generally) as not being in equilibrium or balance. The portrayal of ecological systems as “non-equilibrium” is seen as a strong alternative to deterministic or equilibrium ecology, but this approach fails to provide much theoretical or practical guidance, and warrants formalisation at a more fundamental level. This is available in adaptation (...) theory, which allows population persistence to be explained as an epiphenomenon stemming from the maintenance, survival, movement and reproduction of individual organisms. These processes take place within a physicochemical and biotic environment that persists through structured annual cycles, but which is also spatiotemporally dynamic and subject to stochastic variation. The focus is thus shifted from the overproduction of offspring and the consequent density dependent population pressure thought to follow, to the adaptations and ecological circumstances that support those relatively few individuals that do survive.

A community, for ecologists, is a unit for discussing collections of organisms. It refers to collections of populations, which consist (by definition) of individuals of a single species. This is straightforward. But communities are unusual kinds of objects, if they are objects at all. They are collections consisting of other diverse, scattered, partly-autonomous, dynamic entities (that is, animals, plants, and other organisms). They often lack obvious boundaries or stable memberships, as their constituent populations not only change but also move (...) in and out of areas, and in and out of relationships with other populations. Familiar objects have identifiable boundaries, for example, and if communities do not, maybe they are not objects. Maybe they do not exist at all. The question this possibility suggests, of what criteria there might be for identifying communities, and for determining whether such communities exist at all, has long been discussed by ecologists. This essay addresses this question as it has recently been taken up by philosophers of science, by examining answers to it which appeared a century ago and which have framed the continuing discussion.

To make possible the integration proposed by Domjan et al., psychologists first need to close the research gap between behavioral ecology and the study of Pavlovian conditioning. I suggest two strategies, namely, to adopt more behavioral ecological approaches to social behavior or to co-opt problems already addressed by behavioral ecologists that are especially well suited to the study of Pavlovian conditioning.

This paper is concerned with the ethics of dealing with the dead. In particular, it examines the case of the Kennewick Man—a skeleton discovered in Washington State in 1996. This archaeological find has created a conflict between scientists, who have much to learn by the study of such bones, and some Native Americans, who believe that studying these bones is disrespectful to the dead. A law-suit was launched with the aim of preventing scientific study of the remains of Kennewick Man, (...) but this law-suit was decided in favour of the scientists. I consider three concepts of Selfhood and relate them to the case. First, I consider the concept of Self as an autonomous entity with interests that arise from individual goals. I discuss the limits of such interests after death. Second, I consider the holistic concept of Self described by Deep Ecologists and others. Third, I describe the relational self associated with some feminist philosophers and communitarians to conclude that this idea provides an argument for respecting the dead. It does this in virtue of how it solves “the problem of the nonexistent subject.” Of these threeconceptions of selfhood, only one, the social-relational view, could serve to ground any injunction to leave ancient bones undisturbed. The KennewickMan case could be described as a debate over whether Kennewick Man meets this relational definition of selfhood. (shrink)

Since Krebs and Davies’s (1978) landmark publication, it is acknowledged that behavioural ecology owes much to the ethological tradition in the study of animal behaviour. Although this assumption seems to be right—many of the first behavioural ecologists were trained in departments where ethology developed and matured—it still to be properly assessed. In this paper, I undertake to identify the approaches used by ethologists that contributed to behavioural ecology’s constitution as a field of inquiry. It is my contention that the (...) current practices in behavioural biology owe ethology something much subtler than the simple transposition of Tinbergen’s Four Problems for heuristic purposes. Demonstrating what ethology inherited from the long naturalist tradition shows the tensions that strained the field and that later led to the loss of both its unity and its specificity. It also allows for a precise delineating of what behavioural ecology picked up from the ethological practice, and it helps to cast some light on the introduction of economical thinking in behavioural sciences.

There are two competing conceptions of the nature and domain of ecological science in the popular and academic literature, an orthodox conception and a more expansive conception. The orthodox conception conceives ecology as a natural biological science distinct from the human social sciences. The more expansive conception views ecology as a science whose domain properly spans both the natural and social sciences. On the more expansive conception, non-traditional ecological disciplines such as ecological psychology, ecological anthropology and ecological economics may legitimately (...) be regarded as sub-disciplines of ecology, and the practitioners of such disciplines as ecologists. The orthodox-expansionist issue is significant both for the practice of ecology and for the self-identity of the philosophy of ecology. I argue in favour of the expansionist conception of ecology on general conceptual grounds, and by developing the case for one particular non-traditional ecological discipline, ecological psychology.

The Macarthur-Wilson equilibrium theory of island biogeography has had a contradictory role in ecology. As a lasting contribution, the theory has created a new way of viewing insular environments as dynamical systems. On the other hand, many of the applications of the theory have reduced to mere unimaginative curve-fitting. I analyze this paradox in semiotic terms: the theory was mainly equated with the simple species-area relationship which became a signifier of interesting island ecology. The theory is, however, better viewed as (...) a theoretical framework that suggests specific hypotheses on the ecology of colonization of insular environments. This paradox is inherent in the use of simplifying analytic models. Analytic models are necessary and fruitful in the work of ecologists, but they ought to be supplemented with a broader, pluralistic appreciation of the role of theories in general. (shrink)

A non-productivist Marxism departing from the analysis of capitalism’s “dialectic of scarcity” can make a valuable contribution to the field of environmental ethics. On the one hand, the analysis of capitalism’s dialectic of scarcity shows that the ethical yardstick by which capitalism should be measured is immanent in this social system’s dynamic tendencies. On the other hand, this analysis exposes capitalism’s inability to fulfill the potential for an ecologically sustainable society without unnecessary human suffering that capitalism’s technological dynamism generates. This (...) argument can be illustrated by a critical analysis of Bjorn Lomborg’s The Skeptical Environmentalist. An exploration of capitalism’s dialectic of scarcity can bring to light those weaknesses and internal contradictions of antiecological discourses that are likely to escape the attention of non-Marxist ecologists. This analysis shows that to the extent capitalism’s dialectic of scarcity encourages the fragmentation of social justice and environmental movements, a critical analysis of this dialectic can contribute to the formation of the alliance of emancipatory movements that the attainment of a just and ecologically sustainable society presupposes.

The debates over the future of human population and the earth’s environment, and similar large issues, usually take place without reference to explicit models. Debate would be clarified if such models were employed. We propose that the logistic equation and its extensions like the generalized logistic and the Lotka-Volterra equations, so familiar to ecologists, can easily be modified to model the important "macro" questions that motivated the three thinkers of our title. The long term rate of population growth must (...) normally be controlled by the rate of improvement in K, the carrying capacity of the earth. K will in turn be controlled by the rate of technological progress. The present situation, in which technological improvement (but also perhaps environmental deterioration) are increasing at rates above r, the Malthusian intrinsic rate of natural increase, is probably unique in human history. Can present levels of human prosperity and population growth be sustained? What processes are most likely to determine the answer to this and similar questions? We here sketch a model that endogenizes technological progress and environmental deterioration in the logistic framework. We discuss extensions of the logistic approach to multiple populations, such as other species, and sub-populations, such as human social classes, using the Lotka-Volterra equations. (shrink)

Within the last 20 years, the US has mounted amassive campaign against invasions bynon-indigenous species (NIS) such as zebramussels, kudzu, water hyacinths, and brown treesnakes. NIS have disrupted native ecosystemsand caused hundreds of billions of dollars ofannual damage. Many in the scientificcommunity say the problem of NIS is primarilypolitical and economic: getting governments toregulate powerful vested interests thatintroduce species through such vehicles asships' ballast water. This paper argues that,although politics and economics play a role,the problem is primarily one of scientificmethod. (...) Even if commercial interests werewilling to spend the necessary funds to controlNIS, and even if government were willing toregulate them, ecological theory is notadequate to provide clear direction for eithereffort. The paper argues there is nocomprehensive, predictive theory ofinvasibility, as part of a larger theory ofcommunity structure, that might guideecological decision making regarding NIS, andfor at least three reasons. (1) There is nofirm definition of NIS, native, exotic,and so on, and ecologists do not use the termsconsistently; as a result, biologists debatingvarious accounts of community structure andecological explanation often do not even makelogical contact with each other. (2) Thedominant theory used to understandinvasibility, island biogeography, has noprecise predictive power and is unable toclarify when NIS might promote biodiversity andwhen they might hinder it. (3) There are nofirm, empirical generalizations that revealwhen a colonizer or a NIS might be likely totake over a new environment, and when it mightnot succeed in doing so. As a result,scientists have only rough rules of thumb toshore up their arguments against NIS. Given theincompleteness of current ecological theory,the paper closes with several suggestions forways that study of NIS might enhanceunderstanding of basic commmunity structuresand vice versa.

Deep ecologists have criticized reform environmentalists for not being sufficiently radical in their attempts to curb human exploitation of the nonhuman world. Ecofeminists, however, maintain that deep ecologists, too, are not sufficiently radical, for they have neglected the cmcial role played by patriarchalism in shaping the cultural categories responsible for Western humanity’s domination of Nature. According to eco-feminists, only by replacing those categories-including atomism, hierarchalism, dualism, and androcentrism - can humanity learn to dweIl in harmony with nonhuman beings. (...)

While neither Hegel nor Marx can be called “ecologists” in any strict sense of the term, they both present views of the human-nature relationship which offer important insights for contemporary debates in philosophical ecology. Further, while Marx and Engels began a tradition of sharply distinguishing their own views of nature from those of Hegel, careful examination reveals a substantial commonality of sentiment. The essay compares Hegel and Marx (and Engels) in terms of their basic conceptions of nature, their critiques (...) of Romanitic nature-worship, their notions of how a meaningful unity with nature requires the act of socially transforming nature, their respective calls for a new science of nature, and their attitudes towards technology. I argue that we can uncover a largely shared humanistic orientation toward nature, and I situate this view within contemporary debates about the anthropocentric or non-anthropocentric foundation of ecological thinking.

Traditional ecocentric ethics relies on an ecology that emphasizes the stability and integrity of ecosystems. Numerous ecologists now focus on natural systems that are less clearly characterized by these properties. We use the elimination and restoration of wolves in Yellowstone to illustrate troubles for traditional ecocentric ethics caused by ecological models emphasizing instability in natural systems. We identify several other problems for a stability-integrity based ecocentrism as well. We show how an ecocentric ethic can avoid these difficulties by emphasizing (...) the value of the wildness of natural systems and we defend wildness value from a rising tide of criticisms. (shrink)

Nature in its wider cosmic sense is not at risk from human exploitation and predation. To see life on Earth as but a local manifestation of this wider, indestructable and inexhaustible nature is to shield ourselves from despair over the fate of our Earth. But to take this wide view also appears to make interventionist political action on behalf of nature-which is to say, conservation-superfluous. If we identify with nature in its widest sense, as deep ecology prescribes, then the “self-defence” (...) argument usually advanced by deep ecologists in support of conservation appears not to work. I argue that the need for eco-activism can be reconciled with a rejection of despair within the framework of deep ecology, and that in the process of this reconciliation the meaning of the term conservation acquires a new, spiritual dimension.

We examine the evolution of the concept of stability in community ecology, arguing that biologists have moved from an emphasis on biotic communities characterized by static balance, to one of dynamic balance (returning to equilibrium after perturbation), to the current concept of stability as persistence. Using Wimsatt's (1987) analysis of how false models can often lead to better ones, we argue that failed attempts to link complexity with stability have significant heuristic value for community ecologists. Nevertheless, we argue that, (...) (A) because there is no common characteristic that stability terms presuppose, community ecology might be better served by abandoning the concept of stability and by employing instead specific terms such as 'persistence', 'resistance', and 'variability'. (B) The current emphasis (of stability terms) on persistence of species provides little basis for explaining possible mechanisms that might account for persistence. (shrink)

Summary 1. Ecologists and conservation biologists consider many issues when designing a field study, such as the expected value of the data, the interests of the study species, the welfare of individual organisms and the cost of the project. These different issues or values often conflict; however, neither animal ethics nor environmental ethics provides practical guidance on how to assess trade-offs between them. -/- 2. We developed a decision framework for considering trade-offs between values in ecological research, drawing on (...) the field of ecological ethics. We used a case study of the population genetics of three frog species, in which a researcher must choose between four methods of sampling DNA from the study animals. We measured species welfare as the reduction in population growth rate following sampling, and assessed individual welfare using two different definitions: (i) the level of suffering experienced by an animal, and (ii) the level of suffering combined with loss of future life. -/- 3. Tipping the tails of tadpoles ranked as the best sampling method for species welfare, while collecting whole tadpoles and buccal swabbing of adult frogs ranked best for the first and second definitions of individual welfare, respectively. Toe clipping of adult frogs ranked as the worst sampling method for species welfare and the first definition of individual welfare, and equal worst for the second definition of individual welfare. -/- 4. When considering species and individual welfare simultaneously, toe clipping was clearly inferior to the other sampling methods, but no single sampling method was clearly superior to the other three. Buccal swabbing, collecting tadpoles and tail tipping were all preferred options, depending on the definition of individual welfare and the level of precision with which we assessed species welfare. -/- 5.Synthesis and applications. The decision framework we present can be used by ecologists to assess ethical and other trade-offs when planning field studies. A formal decision analysis makes transparent how a researcher might negotiate competing ethical, financial and practical objectives. Defining the components of the decision in this way can help avoid errors associated with human judgement and linguistic uncertainty. (shrink)

In this article we examine the specific contributions Native American thought can make to the ongoing search for a Western ecological consciousness. We begin with a review of the influence of Native American beliefs on the different branches of the modem environmental movement and some initial comparisons of Western and Native American ways of seeing. We then review Native American thought on the natural world, highlighting beliefs in the need for reciprocity and balance, the world as a living being, and (...) relationships with animals. We conclude that Native American ideas are important, can prove inspirational in the search for a modem environmental consciousness, and affirm the arguments of both deep ecologists and ecofeminists.

Few ontologies in the ecological domain exist, but their development can take advantage of gained experience in other domains and from existing modeling practices in ecology. Taxonomies do not suffice because more expressive modeling techniques are already available in ecology, and the perspective of flow with its centrality of events and processes cannot be represented adequately in a taxonomy. Therefore, formal ontologies are required for sufficient expressivity and to be of benefit to ecologists, which also enables future reuse. We (...) have created a formal mapping between the software-supported ecological modeling method and software tool STELLA and ontology elements, which simplifies bottom-up ontology development considerably and has excellent potential for semi-automated ontology development. However, the conducted experiments also revealed that ontology development for ecology is close to being part of ecological research that through the formalized representation of the knowledge more clearly points to lacunas and suggestions for further research in ecology.

James Lovelock’s “Gaia hypothesis”-the suggestion that life on Earth functions in essential ways as one organism, as a single living entity-is extraordinarily suggestive for environmental philosophy. What exactly it suggests, however, is not yet so clear. Although many of Lovelock’s own ethical conclusions are rather distressing for environmental ethics, there are other possible approaches to the Gaia Hypothesis. Ethical philosophers might take Gaia to be analogous to a “person” and thus to have the same sorts of values that more familiar (...) sorts of persons have. Deep ecologists might find in the Gaia hypothesis a means by which to transform and reunderstand our concrete experience of the world. This essay canvasses some of the strengths, weaknesses, and possibilities of each approach. (shrink)

In the early 1970s, Thomas Colwell argued for an “ecological basis [for] human community.” He suggested that “naturalistic transactionalism” was being put forward by some ecologists and some philosophers of education, but independently of each other. He suspected that ecologists were working on their own versions of naturalistic transactionalism independently of John Dewey. In this essay, Deron Boyles examines Colwell's central claim as well as his lament as a starting point for a larger inquiry into Dewey's thought. Boyles (...) explores the following questions: First, was and is there a dearth of literature regarding Dewey as an ecological philosopher? Second, if a literature exists, what does it say? Should Dewey be seen as biocentric, anthropocentric, or something else entirely? Finally, of what importance are the terms and concepts in understanding and, as a result, determining Dewey's ecological thought in relation to education? (shrink)

Philosophers and ecologists have proposed that ecological principles such as cooperation and ecosystern stability serve as a basis for environmental ethics. Requisite to understanding whether a cooperation based environmental ethic can be taken as an unqualified good is knowledge of the role of cooperation in the context of other interactions between species (e.g., cornpetition), and the significance of such interactions to ecosystem stability. Further, since the key ecological concept of stability has been ambiguously defined, the various definitions need to (...) be understood so that use of scientific information in philosophical discussion is accurate and consistent.

When Kangas suggested in 1986 that wildlife reserve designs could be much smaller than previously thought, community ecologists attacked his views on methodological grounds (island biogeographical theory is beset with uncertainties) and on conservation grounds (Kangas seemed to encourage deforestation and extinction). Kangas' defenders, like Simberloff, argued that in a situation of biological uncertainty (the degree/type of deforestation-induced extinction), scientists ought to follow the epistemologically conservative course and risk type-II error (the risk of not rejecting a null hypothesis that (...) is false), rather than type-I error. (This is the risk of rejecting a null hypothesis that is true). Kangas' opponents, like Noss, argued that, in a situation of scientific uncertainty, scientists ought to risk type-I, rather than type-II, error. This essay argues that there are different types of rationality appropriate to science and applied science and, therefore, in cases of applied science (like conservation biology), the more conservative course of action is for scientists to risk type-I error. The essay argues further that, on grounds of scientific rationality, Kangas, Simberloff, and others were correct in risking type-II error, but that, on grounds of decision-theoretic rationality, Noss, Waide, and others were correct in risking type-I error.

This paper investigates the justification of the concept of a balance of nature in population ecology as a case of model based reasoning. The ecologist A.J. Nicholson understood balance as an outcome of intraspecific competition in populations. His models implied density dependent growth of populations oscillating around an equilibrium state. Today the assumption of density dependence is tested statistically by using models that represent certain data dynamics. This however, does not test for density dependence in the sense suggested by Nicholson. (...) From a suggested mechanism in nature equilibrium has become a property of a data set. I call this a change of reference of the term equilibrium . The new equilibrium is a necessary but not sufficient condition for the old equilibrium. However, some ecologists suggest using the new definition instead of the old one. I argue that the new definition of equilibrium points to a change in justification of the assumption of a balance in nature. This change has to be seen in relation to modeling strategies pursued by the scientific community. I argue that there is an interdependence between models, data, values, and evidence. Model based reasoning, though abstract and idealizing, has to be considered in a historical, philosophical, and social context. (shrink)

Exclusively instrumental notions of rationality not only reinforce attitudes conducive to the destruction of the natural world, but also undermine attempts to construct environmental ethics that involve more harmonious relationships between humans and nature. Deep ecologists and other ecological critics of instrumental rationality generally prefer some kind of spiritual orientation to nature. In this paper I argue against both instrumental rationalists and ecological spiritualists in favor of a communicative rationality which encompasses the natural world. I draw upon both critical (...) theory and recent scientific intimations of agency in nature. (shrink)

The convergence hypothesis asserts that, if one takes the full range of human values—present and future—into account, one will choose a set of policies that can also be accepted by an advocate of a consistent and reasonable nonanthropocentrism. Brian Steverson has attacked this hypothesis from a surprising direction. He attributes to deep ecologists the position that nonhuman nature has intrinsic value, interprets this position to mean that no species could ever be allowed to go extinct, and proceeds to show (...) that my commitment to contextualism prohibits me from advocating the protection of species universally. In response, I show, by reference to recent scientific findings, how difficult it is to defend species preservation in all situations. In particular, I argue that Steverson’s appeal to a possible world in which we have nearly complete biological knowledge misses the point of the convergence hypothesis. It is an empirical hypothesis, with significant indirect, and some direct, evidence to support it. Although it is a falsifiable hypothesis about realworld policies, it cannot be falsified by a contrary-to-fact case. (shrink)
