The most pressing problems facing humanity today - over-population, energy shortages, climate change, soil erosion, species extinctions, the risk of epidemic disease, the threat of warfare that could destroy all the hard-won gains of civilization, and even the recent fibrillations of the stock market - are all ecological or have a large ecological component. in this volume philosophers turn their attention to understanding the science of ecology and its huge implications for the human project. To get the application of ecology (...) to policy or other practical concerns right, humanity needs a clear and disinterested philosophical understanding of ecology which can help identify the practical lessons of science. Conversely, the urgent practical demands humanity faces today cannot help but direct scientific and philosophical investigation toward the basis of those ecological challenges that threaten human survival. This book will help to fuel the timely renaissance of interest in philosophy of ecology that is now occurring in the philosophical profession. Provides a bridge between philosophy and current scientific findings Covers theory and applications Encourages multi-disciplinary dialogue. (shrink)

The status of population genetics has become hotly debated among biologists and philosophers of biology. Many seem to view population genetics as relatively unchanged since the Modern Synthesis and have argued that subjects such as development were left out of the Synthesis. Some have called for an extended evolutionary synthesis or for recognizing the insignificance of population genetics. Yet others such as Michael Lynch have defended population genetics, declaring "nothing in evolution makes sense except in the light of population genetics" (...) (a twist on Dobzhansky's famous slogan that "nothing in biology makes sense except in the light of evolution"). Missing from this discussion is the use of population genetics to shed light on ecology and vice versa, beginning in the 1940s and continuing until the present day. I highlight some of that history through an overview of traditions such as ecological genetics and population biology, followed by a slightly more in-depth look at a contemporary study of the endangered California Tiger Salamander. I argue that population genetics is a powerful and useful tool that continues to be used and modified, even if it isn't required for all evolutionary explanations or doesn't incorporate all the causal factors of evolution.

This paper aims to illustrate one of the primary goals of the philosophy of biology⎯namely, the examination of central concepts in biological theory and practice⎯through an analysis of the concepts of population and metapopulation in evolutionary biology and ecology. I will first provide a brief background for my analysis, followed by a characterization of my proposed concepts: the causal interactionist concepts of population and metapopulation. I will then illustrate how the concepts apply to six cases that differ in their population (...) structure; this analysis will also serve to flesh out and defend the concepts a bit more. Finally, I will respond to some possible questions that my analysis may have raised and then conclude briefly. (shrink)

Writing in 1992, biologist E. O. Wilson prophesied, "Here is the means to end the great extinction spasm. The next century will, I believe, be the era of restoration in ecology." 2 This statement has become the rallying cry for advocates of ecological restoration, an emerging international environmental movement focused on the renewal of damaged or destroyed ecosystems. 3 The benefits promised by ecological restoration are manifold. In addition to its primary ecological goals of replenished biodiversity and improved ecosystem functioning, (...) restoration fosters intimate, participatory kinds of community between practitioners and their local environments. 4 Moreover, the idea that we can ..

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.

This article considers several of the most famous arguments for our being under a moral obligation to preserve species, and finds them all wanting. The most promising argument for preserving all varieties of species might seem to be an aesthetic one. Unfortunately, the suggestion that the moral basis for the preservation of species should be construed as similar to the moral basis for the preservation of a work of art seems to presume (what are now widely regarded as) erroneous conceptualizations (...) of "species". The article concludes by arguing that more promising approaches to how "species" ought to be conceptualized suggest that the preservation of species should be construed as of far greater aesthetic importance than is suggested by focusing upon the preservation of any single work of art. Hence, if we have a moral obligation to preserve a single artwork, then we have a far greater moral obligation to preserve species than has often been presumed. (shrink)

In science and environmental studies, there is a general concern for the democratization of the expert-lay interplay. However, the democratization of expertise does not necessarily lead to more sustainable decisions. If citizens do not take the sustainable choice, what should experts and decision makers do? Should the expert-lay interplay be dissolved? In thinking about how to shape the expert-lay interplay in a better way in agro-biodiversity conservation, I take the case of the MST (Movimento Sem Terra/Landless People’s Movement), possibly the (...) largest rural movement in Latin America. The MST is in a process of turning towards environmentalism. It has adopted agroecology, a democratically oriented knowledge field. However, not all of the farmers were willing to adopt new environmentalist ideas and practices. Through ethnographic research, I analyze how expertise was recognized and redistributed within the MST, attending particularly to the role of MST coordinators and technicians. I explore how participation was framed and put into action. The adoption of agroecology brought to the MST a new and more inclusive map of expertise, but it also influenced new social distinctions within the communities. In part, farmers’ knowledge was labeled as ignorance. This may close down possibilities for dialogue as well as for sustainability. The paper suggests that experts’ power for discriminating among lay knowledges should come together with a responsibility for opening spaces for dialogue and action. One way of doing so could be by adding “interactional reflexivity” to experts’ expertise. (shrink)

The decision-making process of conserving biodiversity within the confines of sustainable livelihoods and development is examined. It is one of the greatest dilemmas facing the conservation community because of the multifaceted nature of activities involved. The case of the conservation of coastal wetlands in Ghana (from 1993 to 1999) is utilised in developing a 'community conservation interface' (CCI) model for the active participation of local communities. The ethical basis of the model is to promote accountability, transparency and responsibility throughout a (...) project's planning and implementation process. Additionally, the CCI model seeks to provide a forum, the CCI seat, for resolving conflicts, developing further partnership and building capacity. It is a decision-making model that is applicable to community-based conservation and partnerships in protected area management. As an adaptive management initiative built on the concept of community conservation, the model is vital for decision-making forums for managing biodiversity at a broad-scale level. Finally it attempts to unravel the true meaning of participation, and the creation of institutional interfaces for the setting of common goals and indicators. (shrink)

Humans have always played a crucial role in the evolutionary dynamics of agricultural biodiversity and thus there is a strong relationship between these resources and human cultures. These agricultural resources have long been treated as a global public good, and constitute the livelihoods of millions of predominantly poor people. At the same time, agricultural biodiversity is under serious threat in many parts of the world despite extensive conservation efforts. Ethical considerations regarding the collecting, research, and use of agricultural biodiversity are (...) currently topics of great concern. For example, easy access to genetic resources for breeding purposes is important, but international agreements and legal frameworks are necessary to ensure adequate recognition of the contributions of local communities and traditional farmers in creating and nurturing these resources. Here, we assess ethical principles in the context of existing codes of conduct that are relevant for agro-biodiversity researchers. We aim to create awareness among scientists and policy makers who are concerned with agro-biodiversity research and its potential impact on local communities. We encourage a serious assessment of the ethical principles presented here and hope to facilitate an integration of these principles into the reader’s personal ethical framework. Key ethical principles considered here include the importance of obtaining prior informed consent, equity, and the inalienability of rights of local communities and farmers. (shrink)

The maintenance of biodiversity is urged from many quarters and on grounds ranging from aesthetic considerations to its usefulness, particularly for biotechnology. But regardless of the grounds for preserving biodiversity, writers are generally in agreement that it should be preserved. But, in examining the various references biodiversity, such as species diversity, genetic diversity, and habitat diversity, it is apparent that we cannot aim to preserve biodiversityas such, since there are a number of conflicts in any such undertaking. In preserving one (...) aspect of biodiversity, we damage another aspect. Five arguments which attempt to ground our moral concern for biodiversity are reviewed and critiqued, not only for their consistency but also for their power to move us to action. The final section of the paper shows how conflicts in the values of personal and environmental health can impair ethical action and especially policy formation. (shrink)

Atran argues that an autonomous ethnobiological information-processing module exists. This module imputes a “deep causal essence” to folk-biological taxa and uses a hierarchy of taxonomic ranks. I argue that Atran's own data suggest that rank is not an essential feature of the ethnobiological module, and that ethnobiological causal essences may be generalized to other domains and vice versa, limiting its autonomy.

Hierarchy of systems organization is used as a framework in advancing methodological guidelines for posing correct questions related to ecological diversity.Diversity if defined in general terms as a property of a set of elements dependent on and determines: by the epistemological perspective. Ontological diversity, because it is indefinite, is regarded as unmeasurable.

Analyses of participation usually assume a dichotomy between 'instrumental' and 'transformative' approaches. However, this study of voluntary biological monitoring experiences and outcomes finds that they cannot be fitted into such a dichotomy. They can enhance the information base for environmental management; change participants through education about scientific practice and ecological change; lead to changes in life direction or group organisation; and influence decision-makers. Personal transformation can take place within a conventionally top-down context. Conversely, grassroots data collection can shore up the (...) status quo and protect local interests. Partnerships between actors can provide distinct but complementary and mutually rewarding outcomes. Power is not located in a data-consuming centre, and data are not meaningless materials that leave the collector unmoved. A more dynamic model of human-nature relations is presented which connects humans and information in the participatory process. (shrink)

What Is Biodiversity? is a theoretical and conceptual exploration of the biological world and how diversity is valued. Maclaurin and Sterelny explore not only the origins of the concept of biodiversity, but also how that concept has been shaped by ecology and more recently by conservation biology. They explain the different types of biodiversity important in evolutionary theory, developmental biology, ecology, morphology and taxonomy and conclude that biological heritage is rich in not just one biodiversity but many. Maclaurin and Sterelny (...) also explore the case for the conservation of these biodiversities using option value theory, a tool borrowed from economics. (shrink)

Science is now studying biodiversity on a massive scale. These studies are occurring not just at the scale of larger plants and animals, but also at the scale of minute entities such as bacteria and viruses. This expansion has led to the development of a specific sub-field of “microbial diversity”. In this paper, I investigate how microbial diversity faces two of the classical issues encountered by the concept of “biodiversity”: the issues of defining the units of biodiversity and of choosing (...) a mathematical measure of diversity. I also show that the extension of the scope of biodiversity to microbial entities such as viruses and many other not-clearly-alive entities raises yet another foundational issue: that of defining a “lower-limit” of biodiversity.

“Offsetting” habitat destruction has widespread appeal as an instrument for balancing economic growth with biodiversity conservation. Requiring proponents to pay the nontrivial costs of habitat loss encourages sensitive planning approaches. Offsetting, biobanking, and biodiverse carbon sequestration schemes will play an important role in conserving biodiversity under increasing human pressures. However, untenable assumptions in existing schemes are undermining their benefits. Policies that allow habitat destruction to be offset by the protection of existing habitat are guaranteed to result in further loss of (...) biodiversity. Similarly, schemes that allow trading the immediate loss of existing habitat for restoration projects that promise future habitat will, at best, result in time lags in the availability of habitat that increases extinction risks, or at worst, fail to achieve the offset at all. We detail concerns about existing approaches and describe how offsetting and trading policies can be improved to provide genuine benefits for biodiversity. Due to uncertainties about the way in which restored vegetation matures, we propose that the biodiversity bank should be a savings bank. Accrued biodiversity values should be demonstrated before they can be used to offset biodiversity losses. We provide recommendations about how this could be achieved in practice. (shrink)

Human activity is causing high rates of biodiversity loss. Yet, surprisingly little is known about the extent to which socioeconomic factors exacerbate or ameliorate our impacts on biological diversity. One such factor, economic inequality, has been shown to affect public health, and has been linked to environmental problems in general. We tested how strongly economic inequality is related to biodiversity loss in particular. We found that among countries, and among US states, the number of species that are threatened or declining (...) increases substantially with the Gini ratio of income inequality. At both levels of analysis, the connection between income inequality and biodiversity loss persists after controlling for biophysical conditions, human population size, and per capita GDP or income. Future research should explore potential mechanisms behind this equality-biodiversity relationship. Our results suggest that economic reforms would go hand in hand with, if not serving as a prerequisite for, effective conservation. (shrink)

The recent conception of biodiversity proposed by James Maclaurin and Sterelny was developed mostly with macrobiological life in mind. They suggest that we measure biodiversity by dividing life into natural units (typically species) and quantifying the differences among units using phenetic rather than phylogenetic measures of distance. They identify problems in implementing quantitative phylogenetic notions of difference for non-prokaryotic species. I suggest that if we focus on microbiological life forms that engage in frequent, promiscuous lateral gene transfer (LGT), and their (...) associated reticulated phylogenies, we need to rethink the notion of species as the natural unit, and we discover additional problems with phylogenetic notions of distance. These problems suggest that a phenetic approach based on morphospaces has just as much appeal, if not more, for microbes as they do for multi-cellular life. Facts about LGT, however, offer no new insight into the additional challenge of reconciling units and differences into a single measure of biodiversity. (shrink)

The multifarious nature of biodiversity is considered in relation to difficulties of definite determination and managerial mandates for monitoring. At a micro scale there is some convergence with the concept of community, but the linkage is largely lost in the spectra of temporal scope, spatial scales, successional seres, and taxonomic trajectories. Practicality points to selecting suitable suites of indicators as surrogates for particular purposes. Domains of partial ordering on multiple indicators constitute comparable collectives, whereas different domains require recognition of special (...) situations. Theoretical treatise and practical process can proceed in parallel, with dialogue and cross-fertilization serving to invigorate and inspire; whereas compulsive concern for completeness and consistency can be counter-productive as well as unduly expensive. Inability to completely capture all aspects of biodiversity in one full formulation is interesting and integral to issues of biocomplexity. (shrink)

While it is commonly acknowledged that the ecosystemic, and the inter- and intra-specific diversity of natural life is under threat of being irremediably lost, there is much less awareness that the diversity in agro-ecosystems is also under threat. This paper is focused on the biodiverse agro-ecosystems generated by landraces (LRs), i.e., farmer-developed populations of cultivated species that show among- and within-population diversity and are linked to traditional cultures. The aim of this work is to arouse concern about their loss, to (...) explain how they can be conserved, and to discuss values that support maintaining and/or restoring on-farm agro-biodiversity. Although agriculture has relied on biodiverse agro-ecosystems for millennia, most of them have disappeared or are disappearing due to profound transformations in the socio-economic context. This is discussed with particular reference to the European situation. The positive values of LRs and LR systems that support their conservation are discussed along with possible objections. The conservation of LRs and LR systems can be well justified on ethical grounds. In particular, the complex intertwining of the biological and cultural contexts of LR systems, which continuously creates new adaptive responses to the changing socio-economic and eco-physical processes, is a value that strongly motivates conservation, particularly when the needs of future generations are considered.

Organic farming is expected to contribute to conserving national biodiversity on farms, especially remnant, old, and undisturbed small biotopes, forests, and permanent grassland. This objective cannot rely on the legislation of organic farming solely, and to succeed, farmers need to understand the goals behind it. A set of indicators with the purpose of facilitating dialogues between expert and farmer on wildlife quality has been developed and tested on eight organic farms. “Weed cover in cereal fields,” was used as an indicator (...) of floral and faunal biodiversity in the cultivated land, and “uncultivated biotope area” on the farm was used as a general measure of wildlife habitats. Functional grouping of herbaceous plants (discriminating between “high conservation value” plant species and “competitive”/“ruderal” species) and low mobility butterflies were used as indicators of conservation value, especially focusing on the few sites left with considerable remnant conservation value. The dialog processes revealed that the organic farmers’ ideas and goals of conservation of wildlife quality were not necessarily the same as for biologists; the farmers expressed very different opinions on the biological rooted idea, that wildlife quality is related to the absence of agricultural impact. However, farmers also stated that the information given by the indicators and especially the dialogue with the biologist had influenced their perception and awareness of wildlife. We conclude that, combined with a dialogue process, using these indicators when mapping wildlife quality could be an important key component of a farm wildlife management advisory tool at farm level.

Sahotra Sarkar’s Biodiversity and Environmental Philosophy is a welcome addition to the fields of environmental philosophy and the philosophy of science. First, his book has a rigorous and careful discussion of why we should preserve biodiversity. This is all the more important since much of environmental ethics has rested on normative claims which are unclear in meaning, appear unjustified at best and unjustifiable at worst, and are politically ineffective. Second, Sarkar is at home in the science of conservation biology and (...) offers important analyses of methodological issues in both ecology and conservation biology. Third, his book does not sustain what might be thought of as a “North American bias” but takes seriously environmental issues and perspectives from many different places like Australia and India. In this commentary, I raise worries and open questions that can be divided into four sections: (a) those concerning moral philosophy, (b) those concerning ecology and in particular whether we are in an extinction crisis, (c) how biodiversity is defined as a concept, and (d) what the aim and structure of conservation biology is. Ultimately, though my analysis is critical at some junctures, its purpose is to repay and hopefully improve on Sarkar’s rewarding analysis. Let me now turn from praise to criticism. (shrink)

This important collection focuses on the nature and importance of biodiversity. Many controversies currently surround biodiversity and a few of them are examined here: What is worthy of protection or restoration, and what is the acceptable level of costs? Is it permissible to kill sentient animals to promote native populations? Can species be reintroduced if they have disappeared a long time ago? How should the responsibilities for biodiversity be shared?

Sahotra Sarkar’s Biodiversity and environmental philosophy, An introduction is an important and timely book. The book is unique in that it is genuinely interdisciplinary: Sarkar is not only an observer, but also an active participant in the new field of conservation biology, and so, his book not only reviews the best recent science, but also advances it. The book is thus exemplary of both a naturalized approach to philosophy of science and a scientifically informed approach to environmental ethics. The book (...) has four parts: a defense of biodiversity preservation, a systematic overview of ecological theory as it pertains to conservation, a critical history of conservation biology, and a discussion of how to prioritize places for conservation. Sarkar integrates nicely the normative and scientific aspects of the problem of conservation. (shrink)

''Biodiversity'' is all to often used as a buzz-word, with no clearly defined meaning, let alone a strict procedure to measure it. This article proposes a logical procedure, based on a similar approach in socio-economics (to measure income inequality). Every element in our logical procedure is known. Bringing it all together as presented is new, as far as we know.

Ricotta argues against the existence of a unique measure of biodiversity by pointing out that no known measure of α-diversity satisfies all the adequacy conditions that have traditionally been set for it. While that technical claim is correct, it is not relevant in the context of defining biodiversity which is most usefully measured by β-diversity. The concept of complementarity provides a closely related family of measures of biodiversity which can be used for systematic conservation planning. Moreover, these measures cannot be (...) replaced by summary statistics but must rely on inventories of biodiversity surrogates at candidate sites for conservation. (shrink)

This book explores the epistemological and ethical issues at the foundations of environmental philosophy, emphasizing the conservation of biodiversity. Sahota Sarkar criticizes previous attempts to attribute intrinsic value to nature and defends an anthropocentric position on biodiversity conservation based on an untraditional concept of transformative value. Unlike other studies in the field of environmental philosophy, this book is as much concerned with epistemological issues as with environmental ethics. It covers a broad range of topics, including problems of explanation and prediction (...) in traditional ecology and how individual-based models and Geographic Information Systems (GIS) technology is transforming ecology. Introducing a brief history of conservation biology, Sarkar analyzes the new consensus framework for conservation planning through adaptive management. He concludes with a discussion of the future directions for theoretical research in conservation biology and environmental philosophy. (shrink)

This paper analyzes the concept of biodiversity in conservation biology and assesses potential methods for its measurement.

Explicit, quantitative procedures for identifying biodiversity priority areas are replacing the often ad hoc procedures used in the past to design networks of reserves to conserve biodiversity. This change facilitates more informed choices by policy makers, and thereby makes possible greater satisfaction of conservation goals with increased efficiency. A key feature of these procedures is the use of the principle of complementarity, which ensures that areas chosen for inclusion in a reserve network complement those already selected. This paper sketches the (...) historical development of the principle of complementarity and its applications in practical policy decisions. In the first section a brief account is given of the circumstances out of which concerns for more explicit systematic methods for the assessment of the conservation value of different areas arose. The second section details the emergence of the principle of complementarity in four independent contexts. The third section consists of case studies of the use of the principle of complementarity to make practical policy decisions in Australasia, Africa, and America. In the last section, an assessment is made of the extent to which the principle of complementarity transformed the practice of conservation biology by introducing new standards of rigor and explicitness.

We argue that ‘locality’, perhaps the most mundane term in ecology, holds a basic ambiguity: two concepts of space—nomothetic and idiographic—which are both necessary for a rigorous resurvey to “the same” locality in the field, are committed to different practices with no common measurement. A case study unfolds the failure of the standard assumption that an exogenous grid of longitude and latitude, as fine‐grained as one wishes, suffices for revisiting a species locality. We briefly suggest a scale‐dependent “resolution” for this (...) replication problem, since it has no general, rational solution. *Received January 2008; revised April 2009. †To contact the authors, please write to: Ayelet Shavit, Department of Interdisciplinary Studies, Tel‐Hai Academic College, Upper Galilee, 12210 Israel; e‐mail: ashavit@telhai.ac.il .

In a world of massive extinctions where not all taxa can be saved, how ought biologists to decide their preservation priorities? When biologists make recommendations regarding conservation, should their analyses be based on scientific criteria, on public or lay criteria, on economic or some other criteria? As a first step in answering this question, we examine the issue of whether biologists ought to try to save the endangered Florida panther, a well known glamour taxon. To evaluate the merits of panther (...) preservation, we examine three important arguments of biologists who are skeptical about the desirability of panther preservation. These arguments are (1) that conservation dollars ought to be spent in more efficient ways than panther preservation; (2) that biologists and conservationists ought to work to preserve species before subspecies; and (3) that biologists and conservationists ought to work to save habitats before species or subspecies. We conclude that, although all three arguments are persuasive, none of them provides convincing grounds for foregoing panther preservation in favor of other, more scientifically significant conservation efforts. Our conclusion is based, in part, on the argument that biologists ought to employ ethical, as well as scientific, rationality in setting conservation priorities and that ethical rationality may provide persuasive grounds for preserving taxa that often are not viewed by biologists as of great importance.

"At places distant from where you are, but also uncomfortably close," writes David Takacs, "a holocaust is under way. People are slashing, hacking, bulldozing, burning, poisoning, and otherwise destroying huge swaths of life on Earth at a furious pace." And a cadre of ecologists and conservation biologists has responded, vigorously promoting a new definition of nature: biodiversity--advocating it in Congress and on the Tonight Show; whispering it into the ears of foreign leaders redefining the boundaries of science and politics, ethics (...) and religion, nature and our ideas of nature. These scientists have infused the environmental movement with new focus and direction, but by engaging in such activities, they jeopardize the societal trust that allows them to be public spokespersons for nature in the first place. The Idea of Biodiversity analyzes what biodiversity represents to the biologists who operate in broader society on its behalf, drawing on in-depth interviews with the scientists most active today in the mission to preserve biodiversity, including Peter Raven, Thomas Lovejoy, Jane Lubchenco, and Paul Ehrlich. Takacs explores how and why these biologists shaped the concept of biodiversity and promoted it to society at large--examining their definitions of biodiversity their opinions about spirituality and its role in scientific work the notion of biodiversity as something of intrinsic value and their views on biophilia, E. O. Wilson's idea that humans are genetically predisposed to love nature. Takacs also looks at the work of twentieth-century forerunners of today's conservation biologists--Aldo Leopold, Charles S. Elton, Rachel Carson, David Ehrenfeld--and points out their contributions to the current debates. He takes readers to Costa Rica, where a group of scientists is using biodiversity to remake nature and society. And in an extended section, he profiles the thoughts and work of E. O. Wilson. "When I'm asked, 'should we save this species orthat species, or this place or that place?' the answer is always 'Yes!' with an exclamation point. Because it's obvious . And if you ask me to justify it, then I switch into a more cognitive consciousness and can start giving you reasons, economic reasons, aesthetic reasons. They're all dualistic, in a sense. But the feeling that underlies it is that 'yes!' And that 'yes!' comes out of the affirmation of being part of it all, being part of this whole evolutionary process. And agreeing with Arne Naess that each species, each entity, should be allowed to continue its evolution and to live out its destiny... just do its thing, as we say. Why not? And the 'why not?' is there's too many people."--Michael E. Soule, from an interview in The Idea of Biodiversity "An important contribution, a first distanced examination of a critical, modern topic by a scholarly, honest broker."--E. O.

This essay argues that Merleau-Ponty’s concept of nature as a “privileged expression” of ontology provides the conceptual support for a more responsible attitude toward humans and nature. Furthermore, this concept of nature needs to be viewed in the light of a more profound concept that opens a new vision of the human being’s place in the world, namely Merleau-Ponty’s fields of perception. Shiva’s writings pertaining to the environment gain a more profound, yet critical, understanding when viewed in this way. Similarly, (...) Merleau-Ponty’s attempts “to reconcile the old world and the new” (MP 1964, 4) through implementation of his phenomenology to political and ethical questions is reviewed anew. (shrink)

Recent research has focused on establishing the values of preserving biodiversity both in agriculture and in less managed ecosystems, and in showing the importance of the role of cultural diversity in preserving biodiversity in food production systems. A study of the philosophy embedded in cultural systems can reveal the importance of the technological information for preserving genetic biodiversity contained in such systems and can be used to support arguments for the protection/preservation of cultural diversity. For example, corn or maize can (...) serve as a paradigm of Native American thinking and can provide one of the few areas from which common philosophical conceptions can emerge. An examination of the cultivation of corn or maize as an agricultural activity and as a cultural activity in Native American literature reveals a philosophy that recognizes the importance of biodiversity and provides techniques for its preservation. Corn, and the food and the materials derived from it, is something thought out, not by specialists, but by the entire tribe and its ancestors, even if this thinking is done within what we might consider a framework of highly mythical notions. Importantly, this framework yields an understanding of both the genetics and nutrition of corn. A survey of these mythical notions (myths and stories) and agricultural practices makes this thought explicit and exemplifies the value of cultural diversity and biodiversity. (shrink)

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)

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.

Long-term vegetation dynamics based on paleo-pollen data display transient behaviour, often alternating in phase between predominant determinism and predominant 'turbulence', when viewed as a trajectory in a multivariate phase space. Given this, the metaphor of vegetation dynamics as a 'flowing stream', first introduced by Cooper in his classic 1926 paper entitled "The fundamentals of vegetation change", is re-examined and revealed to be not only useful, but strikingly realistic. Vegetation dynamic theory is reviewed and classic theories are found to reflect reality (...) poorly. It is suggested that vegetation dynamics is a far from equilibrium system, and that the application of nonequilibrium thermodynamic theory is appropriate. (shrink)

E. O. Wilson (1974: 54) describes the problem that social organisms pose: “On what bases do we distinguish the extremely modified members of an invertebrate colony from the organs of a metazoan animal?” This framing of the issue has inspired many to look more closely at how groups of organisms form and behave as emergent individuals. The possible existence of “superorganisms” test our best intuitions about what can count and act as genuine biological individuals and how we should study them. (...) As we will discuss, colonies of certain organisms display many of the properties that we usually reserve only to individual organisms. Although there is good reason to believe that many social insects form genuine emergent biological individuals, the conclusion offered here is of a slightly different sort. I will argue that to understand some social insects' interactions and the emergent traits they give rise to, it may be helpful to shift our understanding from a community-level approach to an ecosystem-level approach. I will argue that viewing certain insect colonies (termites) as parts of ecosystems allows us to better understand some of the adaptations that have emerged from their evolution. (shrink)

Recent deconstructive developments in ecology (doubts about the existence of unified communities and ecosystems, the diversity-stability hypothesis, and a natural homeostasis or “balance of nature”; and an emphasis on “chaos,” “perturbation,” and directionless change in living nature) and the advent of sociobiology (selfish genes) may seem to undermine the scientific foundations of environmental ethics, especially the Leopold land ethic. A reassessment of the Leopold land ethic in light of these developments (and vice versa) indicates that the land ethic is still (...) a viable environmental ethic, if judiciously updated and revised.

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)

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)

A good philosophical understanding of ecology is important for a number of reasons. First, ecology is an important and fascinating branch of biology, with distinctive philosophical issues. Second, ecology is only one small step away from urgent political, ethical, and management decisions about how best to live in an apparently fragile and increasingly-degraded environment. Third, philosophy of ecology, properly conceived, can contribute directly to both our understanding of ecology and help with its advancement. Philosophy of ecology can thus be seen (...) as part of the emerging discipline of “biohumanities”, where biology and humanities disciplines together advance our understanding and knowledge of biology (Stotz and Griffiths 2008). In this paper, we focus primarily on this third role of the philosophy of ecology and consider a number of places where philosophy can play an important role in ecology. In the process, we survey some of the current research being done in philosophy of ecology, as well as make suggestions about the agenda for future research in this area. We also hope to help clarify what philosophy of ecology is and what it should aspire to be. In what follows, we discuss several topics in the philosophy of ecology and conservation biology, starting with the role and understanding of mathematical models. This is followed by a discussion of a couple of practical problems involving the standard model of hypothesis testing and the use of decision-theoretic methods in environmental science. We then move on to discuss the issue of how we should understand biodiversity, and why this matters for conservation management. Finally, we look at environmental ethics and its relationship with ecology and conservation biology. These four topics were chosen because they are all of contemporary interest in philosophy of ecology circles and are ones where there is much fruitful work still to be done. The topics in question are also useful vehicles for highlighting the variety of issues in ecology and conservation biology where philosophy might prove useful.. (shrink)

Philosophical interest in ecology is relatively new. Standard texts in the philosophy of biology pay little or no attention to ecology (though Sterelny and Griffiths 1999 is an exception). This is in part because the science of ecology itself is relatively new, but whatever the reasons for the neglect in the past, the situation must change. A good philosophical understanding of ecology is important for a number of reasons. First, ecology is an important and fascinating branch of biology with distinctive (...) philosophical issues that arise from its study. Second, ecology is only one small step away from urgent political, ethical, and management decisions about how best to live in an apparently increasingly-fragile environment. Third, philosophy of ecology, properly conceived, can contribute directly to both our understanding of ecology and help with its advancement. Philosophy of ecology can thus be seen as part of the emerging discipline of “biohumanities”, where biology and humanities disciplines together advance our understanding and knowledge of biology (Stotz and Griffiths forthcoming). In this paper, we focus primarily on this third role of the philosophy of ecology and consider a number of places where philosophy can play an important role in ecology. In the process, we..

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)

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.

This book is the first examination in almost a decade of issues in the philosophy of ecology that have been a source of controversy since the existence of ecology as an explicit scientific discipline. The controversies revolve around the idea of a balance of nature, the possibility of general ecological knowledge and the role of model-building in ecology. The Science of the Struggle for Existence is also the first sustained treatment of these issues that incorporates both a comprehensive investigation of (...) the relevant ecological literature and the development of an explicit theoretical framework in the philosophy of science. It addresses issues in the philosophy of ecology that are of particular importance for the deployment of ecology in the solution of environmental problems. It will have a cross-disciplinary appeal and will interest students and professionals in science, the philosophy of science, environmental studies as well as policy-makers. (shrink)

This article discusses whether ecology represents an alternative type of natural science, that is normatively committed. Central questions are:-how man and human action are integrated into the subject matter of ecology.

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.

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)

The complexity and heterogeneity of causes influencing ecology’s domain challenge its capacity to generate a general theory without exceptions, raising the question of whether ecology is capable, even in principle, of achieving the sort of theoretical success enjoyed by physics. Weber has argued that competition theory built around the Competitive Exclusion Principle (especially Tilman’s resource-competition model) offers an example of ecology identifying a law-like causal regularity. However, I suggest that as Weber presents it, the CEP is not yet a causal (...) regularity. Instead, I argue that the scientific understanding in Tilman’s theory takes a different form. The theory explains through a structure I call “channeling explanation” which does not depend on deduction from general laws, but rather builds on constraints and trade-offs represented in state-space. Recognizing this structure supports the more general point that ecology and other so-called special sciences can reveal novel theoretical approaches to philosophy of science when approached with openness to their uniqueness.

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.

This paper examines the identity of Asian swamp buffalo ( Bubalus bubalis ) from different value orientations. Buffalo were introduced into Northern (Top End) Australia in the early nineteenth century. A team of transdisciplinary researchers, including an ethicist, has been engaged in field research on feral buffalo in Arnhem Land over the past three years. Using historical documents, literature review, field observations, interviews with key informants, and interaction with the Indigenous land owners, an understanding of the diverse views on the (...) scientific, cultural, and economic significance of buffalo was obtained. While the diverse stakeholders in buffalo exploitation and management have historically delivered divergent value orientations on the nature of the human–buffalo relationship, we argue that over time there is the possibility of values and ethical convergence. Such convergence is possible via transdisciplinary and transcultural agreement on the value stances that constitute the construction of the being or identity of buffalo in the face of the overwhelming need to manage population density and gross numbers.
