Habitat templets are graphical-qualitative models which describe the development of life-history strategies in specific environmental conditions. In the context of the previous models of life-history strategies, life-history theorists focused on the density-dependent factors as the factors determining life-history strategies. With the use of habitat templets, the focus is oriented towards the environmental causal factors, considering density-dependent phenomena as by-products of the environmental impact. This implies an important shift in causality as well as in the worldview of life-history theorists: (...) population is not considered as a closed system isolated from the environment. The object of study is the organism-in-its-environment, as a complex multilevel system. This shift has also methodological consequences: Life-history theory combines holistic and reductionistic insights, using a variety of heuristic models. This imposes a new conception of generality as well as of the structure of scientific theories. (shrink)

Darwin's phrase “place in natural economy”, andSpencer's term “correspondence” can be regarded as first attempts to express the organism-environment relationships. The same concept has more recently been approached from the point of view of life-form, external activities, and habitat. Though all these points are interlocking, they have been stressed differently in the writings of American and European ecologists. It is proposed that the term “niche” would be most useful and rational if applied to the total of relationships between a (...) living organism and its complete environment, both biotic and abiotic.

These investigations identify and clarify some basic assumptions and methodological principles involved in ecological explanations of plant associations. How are plants geographically distributed into characteristic groups? What are the basic conditions that organize groups of interspecific plant populations that are characteristic of particular kinds of habitats? Answers to these questions concerning the geographical distribution of plants in late 19th century European plant geography and early 20th century American plant ecology can be distinguished according to differing logical assumptions concerning the (...) habitats of plant associations. Through an analysis of several significant case studies in the early history of plant ecology, Konopka distinguishes a logic of habitats that conceives of plant associations in an analogy to individual organisms with a logic that conceives of plant associations in a reciprocal relation to habitat physiography. He argues that a phenomenological conception of the logical attributes of habitats can philosophically complement the physiographic tradition in early plant ecology and provide an attractive alternative to standard reductionism and holism debates that persist today. This wide ranging and original analysis will be valuable for readers interested in the history and philosophy of ecology. (shrink)

Over two decades ago, Davids et al. (1994) and Handford et al. (1997) raised theoretical concerns associated with traditional, reductionist, mechanistic perspectives of movement coordination and skill acquisition for sport scientists interested in practical applications for training designs. These seminal papers advocated an emerging consciousness grounded in an ecological approach, signalling the need for sports practitioners to appreciate the constraints-led, deeply entangled and non-linear reciprocity between the organism (performer), task and environment subsystems. Over two decades later, the areas of skill (...) acquisition, practice and training design, performance analysis and preparation, and talent development in sport science have never been so vibrant in terms of theoretical modelling, knowledge generation and innovation, and technological deployment. Viewed at an ecological level of analysis, the work of sports practitioners has progressively transitioned toward the facilitation of an evolving relationship between an organism (athlete, team) and its environment (sports competition). This commentary sets out to explore how these original ideas from Davids et al. (1994) and Handford et al. (1997) have been advanced through the theoretical lens of Ecological Dynamics. Concurrently, we provide case study exemplars, from applied practice in high-performance sports organisations, to illustrate how these contemporary perspectives are shaping the work of sports practitioners (sport ecology designers) in practice and performance preparation.

A phenomenological community is an identifiable assemblage of organisms in a local habitat patch: a local wetland or mudflat are typical examples. Such communities are typically persistent: membership and abundance stay fairly constant over time. In this paper I discuss whether phenomenological communities are functionally structured, causal systems that play a role in determining the presence and abundance of organisms in a local habitat patch. I argue they are not, if individualist models of community assembly are vindicated; i.e., (...) if the presence of one species is not typically explained by the presence or absence of specific other species. I discuss two alternatives to in- dividualism, and conclude by arguing for a dimensional model of phenomenological communities. The causal salience of a phenomenological community depends on three factors: the extent to which it is internally regulated, the extent to which it has robust boundaries, and the extent to which it has emergent properties. I conclude by using this model to frame a natural research agenda for community ecology. (shrink)

Developmental biology is a theory of interpretation. Developmental signals are interpreted differently depending on the previous history of the responding cell. Thus, there is a context for the reception of a signal. While this conclusion is obvious during metamorphosis, when a single hormone instructs some cells to proliferate, some cells to differentiate, and other cells to die, it is commonplace during normal development. Paracrine factors such as BMP4 can induce apoptosis, proliferation, or differentiation depending upon the history of the responding (...) cells. In addition, organisms have evolved to alter their development in response to differences in temperature, diet, the presence of predators, or the presence of competitors. This allows them to develop the phenotype, within the limits imposed by the genotype, best suited for the immediate habitat of the organism. Most developing organisms have also evolved to expect developmental signals from symbionts, and these organisms develop abnormally if the symbiont signals are not present. Thus Hoffmeyer’s “vertical semiotic system” of genetic communication and “horizontal semiotic system” of ecological communication are integrated during development. (shrink)

In the present condition of planetary environmental crises, violence, and war, entire ecosystems are annihilated, habitats turn into unliveable spaces, and shared “more-than-human” vulnerabilities get amplified. Here and now, death and loss become urgent environmental concerns, while the Anthropocene-induced anxiety, anger, and grief are manifested in popular-scientific narratives, art, culture, and activism. Grounded in the theoretical framework of queer death studies, this article explores present grief imaginaries and engagements with more-than-human death, dying, and extinction, as they are interwoven through contemporary (...) art. It is there where an ecological ontology of death is being exposed and ethical territories of eco-grief unfold. (shrink)

An ecological study of the city is a new endeavor. Up to now, we have mostly been given inquiries dealing with transportation, housing, economic activity, recreational facilities, etc. All of this adds up to an attempt to reach partial solutions for problems affecting sub-systems. Urbanists and city planners have tried to reach a synthesis of these data whenever they were available.There is an ever increasing need to approach urban problems by borrowing the concepts and the methodology of ecology The (...) origins of this science stem from the research pertaining to plant and animal behavior in their natural habitat. Highly complex adaptation patterns could frequently be observed which allowed a large number of species not only to survive but also to attain a certain level of compatibility with other species. One need not be a determinist to recognize the common basis of adaptation for man and other animals and to tie together the physical and biological needs which underlie more complex individual and group behavior. Thus, for instance, von Frisch and Wilson - have recently redefined the biological bases of the noosphere. (shrink)

This article submits a proposal to replace the term sustainability with the term ‘ecological justice’. This novel expression adds to the term Anthropocene, which largely ignores the significant differences from the perspective of justice concerning which human cultures have profoundly reshaped the Earth. Ecological justice refers to the fact that the Earth is the habitat not only of human beings but also of a multitude of other life forms and includes the rights of nonhuman creatures. Over and above this, (...) the term ecological justice speaks to the rights of marginalised people who suffer because of the destruction of natural resources without having significantly contributed to their misuse. In this sense, a new orientation toward the integrity of creation is necessary to overcome the one-sided technicist and economically determined attitude that has become so typical of modern thinking in the Global North. Churches are challenged to develop an integrative concept of ecological justice from the perspective of the biblical tradition, including recent initiatives such as the ‘Wuppertal Call’.Contribution: To overcome generalising and anthropocentric perspectives, the proposal of this article argues for the preferred term, ‘ecological justice’. This term is inclusive to nonhuman communities in nature, taking into account the effects of environmental destruction on marginalised people. The challenge should be to develop an integrative and unifying concept of ecological justice. The following contribution addresses the question of semantics concerning the key concepts underpinning ecological challenges. (shrink)

Ethical implications of the concept of ecological space can be drawn from the focus it brings to issues arising from the finitude and vulnerability of habitats. An evident ethical concern is that each person should have sufficient access to support at least a minimally decent life. The demands placed by the world’s human population on its ecological space, however, are such that some members do not have enough of it for their health and well-being. One aspect of this problem is (...) the finitude of the earth’s aggregate biophysical capacity; another is that some humans make vastly more use of the planet’s ecological space than others do. In relation to the normative assessment and regulation of human activities, I recommend differentiating between using, occupying, and commanding ecological space. It is in relation to these activities that deontic categories—of prescription, proscription and permission—can be applied. (shrink)

Recent severe environmental crises have brought us to recognize the need for a broad reevaluation of the relation of humans to their environments. I suggest that we consider the human-nature relation from two overlapping perspectives, each informed by the pragmatic philosophy of expeIience. The first is an anthropology, according to which humans are viewed as being radically continuous with their environments. The second is a comprehensive ecology, according to which both “natural” and “nonnatural” environments are studied as artificial habitats (...) of the human organism. The pragmatic approach has two features which make it promising as a way to ground environmental thinking. First, it allows us to avoid a human-nature dichotomy and the many problems which that dichotomy has traditionally engendered. Second, it ties environmental questions to a common cultural experience and a philosophical position from which environmentalists can effectively engage mainstreameducational and political discussions.

Habitat fragmentation produces isolated patches characterized by increased edge effects from an originally continuous habitat. The shapes of these patches often show a high degree of irregularity: their shapes deviate significantly from regular geometrical shapes such as rectangular and elliptical ones. In fractal theory, the geometry of patches created by a common landscape transformation process should be statistically similar, i.e. their fractal dimensions and their form factors should be equal. In this paper, we analyze 49 woodlot fragments (Pinus (...) sylvestris L.) in the Belgian Kempen region to study the direct relationship between a transformation process and the concomitant patch geometry. Although the fractal dimension of the woodlots is scattered (i.e. they are not statistically similar), the perimeter-area relation of the fragments is characterized by a single, ‘dimension-like’ exponent. This exponent suggests a certain shape homogeneity among the patches, which is confirmed by the absence of hierarchical levels associated with sharp increases of the fractal dimension at scale transitions. The interaction of different natural (soil factor, vegetation type) and anthropogenic (afforestation, urbanization) processes during patch development is assumed to have generated this feature. Comparison of the area and perimeter fractal dimension with an ecological index for habitat quality, the interior-to-edge ratio, shows that the fractal dimension is suitable for predicting interior habitat presence, which is more likely for patches with smooth perimeters and compact areas. The ratio of the area to the perimeter fractal dimension confirms this observation, with high values for high interior-to-edge ratios, characteristic for regularly shaped patches. (shrink)

Prepared for an ANU Humanities Research Centre Symposium in early August 2003, these notes may be considered as a comment on Brian Massumi’s proposition that ‘a political ecology would be a social technology of belonging, assuming coexistence and co-becoming as the habitat of practices’.

Kenya has one of the highest remaining concentrations of tropical savanna wildlife in the world. It has been recognised by the state and international community as a 'unique world heritage' which should be preserved for posterity. However, the wildlife conservation efforts of the Kenya government confront complex and often persistent social and ecological problems, including land-use conflicts between the local people and wildlife, local people's suspicions and hostilities toward state policies of wildlife conservation, and accelerated destruction of wildlife habitats. This (...) essay uses a political -ecological framework in the analysis of the social factors of wildlife conservation in Kenya. It postulates that the overriding socioeconomic issue impacting wildlife conservation in Kenya is underdevelopment. The problem of underdevelopment is manifested in forms of increasing levels of poverty, famine and malnutrition. The long term survival of Kenya 's wildlife depends on social and ecological solutions to the problems of underdevelopment. (shrink)

In landscape ecology spatial descriptors (or indices) can be used to characterize habitats. Some of these descriptors can be used for habitat's ranking; this ranking is very important for conservation purposes. We would like to show that two traditional descriptors, namely the compactness and interior-to-edge ratio can give contradictory results. Being the second one is a more relevant descriptor, we would like to propose to avoid the further use the compactness in habitat's ranking.

The concept of an ecological niche (econiche) has been used in a variety of ways, some of which are incompatible with a relational or functional interpretation of the term. This essay seeks to standardize usage by limiting the concept to functional relations between organisms and their surroundings, and to revise the concept to include epistemic relations. For most organisms, epistemics are a vital aspect of their functional relationships to their surroundings and, hence, a major determinant of their econiche. Rejecting the (...) traditional dualism of organism and environment, an econiche is defined as the reciprocal (dual) of a functionally specified class of organisms (FSTU). From this perspective, an econiche necessarily implies a certain type of organism, and a class of functionally similar organisms implies a special econiche.The econiche concept is also discussed in relation to other ecological terms that reflect the distributional patterns of organisms, such as habitat, and the concept of an empty niche is criticized.

In the contemporary context of environmental crises and the degradation of resources, certain habitats become unliveable, leading to the death of individuals and species extinction. Whilst bioscience emphasises interdependency and relationality as crucial characteristics of life shared by all organisms, Western cultural imaginaries tend to draw a thick dividing line between humans and nonhumans, particularly evident in the context of death. On the one hand, death appears as a process common to all forms of life; on the other, as an (...) event that distinguishes human from other organisms. Against this background, this article explores how contemporary art—in particular, the series of works The Absence of Alice by Australian new-media and bioartist Svenja Kratz—challenges the normative and human-exceptionalist concept of death. By employing queerfeminist biophilosophy as a strategy that focuses on relations, processes and transformations instead of ‘essences’, the article examines the ways Kratz’s works deterritorialise the conventional concept of death. In this way, it hopes to attend to the intimacies between materialities of a human and nonhuman kind that form part of the processes of death and dying, and what follows, to reframe ethico-ontology of death as material and processual ecologies of the non/living.

The Majangir live on the thickly forested slopes of the south-western edge of the Ethiopian plateau, between the Anuak of the plains and the Galla of the highlands. Their way of life is markedly different from that of their neighbours, and is well adapted to their habitat. They are agriculturalists and the structure of their society is loose and simple. They have no political leaders, the only individuals of any authority being ritual leaders whose influence is restricted. Domestic groups (...) tend to farm plots adjacent to those of friends or kin, but the settlements remain small and constantly change in composition. In addition to farming, in which the men and women share the work, the men make occasional hunting and fishing trips, as well as spending quite a considerable amount of time tending and making bee hives. Dr Stauder examines the various social and spatial groupings of Majang society and demonstrates the intimate ecological relationship between these groupings and the system of slash and burn cultivation practised by the Majangir.

Industrialized agriculture currently substitutes many of the ecological functions of soil micro-organisms, macroinvertebrates, wild plants, and vertebrate animals with high cost inputs of pesticides and fertilizers. Enhanced biological diversity potentially offers agricultural producers a means of reducing the cost of their production. Conservation of biodiversity in agricultural landscapes may be greatly enhanced by the adoption of certain crop management practices, such as reduced pesticide usage or measures to prevent soil erosion. Still, the vast monocultures comprising the crop area in many (...) Canadian agricultural landscapes are often of limited conservation value, thus the inclusion of appropriate wildlife habitat in and around arable lands is a fundamental prerequisite for the integration of wild species within agricultural landscapes. This review of current literature considers the potential for non-crop areas within agricultural landscapes to be reservoirs of agronomically beneficial organisms including plants, invertebrates, and vertebrate species. Non-crop habitats adjacent to crop land have been identified as significant for the maintenance of plant species diversity, for the conservation of beneficial pollinating and predatory insects, and as essential habitat for birds. A key component for enhancement of biodiversity is the reintroduction of landscape heterogeneity by (1) protection and enhancement of key non-crop areas, (2) smaller fields and farms, and (3) a greater mixture of crops, through rotation, intercropping and regional diversification. The benefits of increased biodiversity within arable lands are reviewed for various species groups. In the Canadian context, any serious attempt to derive significant agronomic benefit from increased biodiversity will require considerable changes in the agricultural programs and policies which shape mainstream industrialized agriculture. The problems of crop depredation by vertebrate species, weed and insect competition, which still represent significant impediments to the creation and proper management of wildlife habitat, are also discussed.

We emphasize the value of the socio-ecological approach in addressing the problem of population variances. The socio-ecological perspective studies how social and natural habitats shape human behaviors, and are in turn shaped by those behaviors. This focus on system-level factors is particularly well-suited to studying the origins of group differences in human behavior.

An ecological focus is not simply an additional perspective to add to a multidimensional approach to feminist theologies. Ecological thinking requires a fundamental shift of perspective, so that the focus of feminism, traditionally a human focus, is rethought within the frame of the materiality that constitutes not only humans but Earth and cosmos. As a way of situating feminist theological discourses and experiences ecologically, this article focuses on a shared materiality as a basis for reframing human being, dwelling, agency and (...) labour, in terms of co-being, habitat, co-agency and more-than-human labour. This reframing implies a rethinking of human freedom that has implications for how we engage with feminist theologies in relation to the future of Earth and humankind. (shrink)

Baggs and Chemero (2018) propose that certain tensions between enaction and ecological psychology arise due different interpretations about what is meant by the “environment.” In the enactive approach the emphasis is on the umwelt, which describes the environment as the “meaningful, lived surroundings of a given individual.” The ecological approach, on the other hand, emphasises what they refer to as the habitat “the environment as a set of resources for a typical, or ideal, member of a species.” By making (...) this distinction, these authors claim they are able to retain the best of both the ecological and the enactive approaches. Herein I propose an account of the individuation of habits that straddles this distinction, what I call a compatabilist account. This is done in two parts. The first part teases out a host of compatibilities that exist between the enactive account as developed by Di Paolo et al. (2017) and the skilled intentionality framework as developed by Bruineberg and Rietveld (2014) and Rietveld and Kiverstein (2014). In part two these compatibilities are brought together with the philosophy of Gilbert Simondon to develop the notion of enhabiting. Enhabiting describes a set of ongoing processes by which an umwelt emerges from and is reproduced within the relationship between an embodied subject and their habitat. Thus, enhabiting points toward a point of intersection between enaction and ecological psychology. To enhabit is bring forth (to enact), within (to inhabit). (shrink)

Niche construction theory (NCT) aims to transform and unite evolutionary biology and ecology. Much of the debate about NCT has focused on construction. Less attention has been accorded to the niche: what is it, exactly, that organisms are constructing? In this paper I compare and contrast the definition of the niche used in NCT with ecological niche definitions. NCT’s concept of the evolutionary niche is defined as the sum of selection pressures affecting a population. So defined, the evolutionary niche (...) is narrower than the ecological niche. Moreover, when contrasted with a more restricted ecological niche concept, it has a slightly different extension. I point out three kinds of cases in which the evolutionary niche does not coincide with realized ecological niches: extreme habitat degradation, commensalism, and non-limiting or super-abundant resources. These conceptual differences affect the role of NCT in unifying ecology and evolutionary biology. (shrink)

This paper contributes to biodiversity and species extinction literature by examining the relationship between corporate accountability in terms of species protection and factors affecting such accountability from forward-thinking companies. We use triangulation of theories, namely deep ecology, legitimacy, and we introduce a new perspective to the stakeholder theory that considers species as a ‘stakeholder’. Using Poisson pseudo-maximum likelihood regression, we examine a sample of 200 Fortune Global companies over 3 years. Our results indicate significant positive relations between ecologically conscious (...) companies that are accountable for the protection of biodiversity and species extinction and external assurance, environmental performance, partnerships with socially responsible organizations and awards for sustainable activities. Our empirical results appear to be robust in controlling for possible endogeneities. Our findings contribute to the discussion on the concern of species loss and habitat destruction in the context of corporate accountability, especially in responding to the sixth mass extinction event and COVID-19 crisis. Our results can also guide the policymakers and stakeholders of the financial market in better decision making. (shrink)

Natural selection is often envisaged as the ultimate cause of the apparent rationality exhibited by organisms in their specific habitat. Given the equivalence between selection and rationality as maximizing processes, one would indeed expect organisms to implement rational decision-makers. Yet, many violations of the clauses of rationality have been witnessed in various species such as starlings, hummingbirds, amoebas and honeybees. This paper attempts to interpret such discrepancies between economic rationality and biological rationality. After having distinguished two kinds of rationality (...) we introduce irrationality as a negation of economic rationality by biologically rational decision-makers. Focusing mainly on those instances of irrationalities that can be understood as exhibiting inconsistency in making choices, i.e. as non-conformity of a given behaviour to axioms such as transitivity or independence of irrelevant alternatives, we propose two possible families of Darwinian explanations that may account for these apparent irrationalities. First, we consider cases where natural selection may have been an indirect cause of irrationality. Second, we consider putative cases where violations of rationality axioms may have been directly favored by natural selection. Though the latter cases seem to clearly contradict our intuitive representation of natural selection as a process that maximizes fitness, we argue that they are actually unproblematic; for often, they can be redescribed as cases where no rationality axiom is violated, or as situations where no adaptive solution exists in the first place.

Multi-stakeholder initiatives for biodiversity conservation on working landscapes often necessitate strategies to facilitate learning in order to foster successful collaboration. To investigate the learning processes that both undergird and result from collaborative efforts, this case study employs the concept of boundary work as a lens to examine learning between rice growers and conservation professionals in California’s Central Valley, who were engaged in a collaborative research project focused on migratory bird conservation. Through analysis of workshop observations, project documents, and interviews with (...) rice growers and conservation professionals, we identified five distinct factors of the collaborative research process that influenced learning amongst these two groups: having mutually beneficial goals, sharing ownership of the collaborative research process, building trust, integrating knowledge, and institutional alignment. We also examined and identified learning outcomes for both rice growers and conservation professionals, which included new knowledge of the social-ecological system, new practices around farming and collaboration, and shifting identities. Our findings suggest that applying these factors and outcomes for learning when structuring collaborative research, and other multi-stakeholder initiatives, can foster learning amongst diverse stakeholder groups to support new approaches for balancing resource use and adaptive management.

The variety of nature presents a challenge for ecologists. Individual organisms differ from one another in ways both obvious and subtle, even if they’re members of the same species living in the same location. Different populations, species, communities, ecosystems, biomes, habitats, food webs, etc. also differ from another. What, if anything, can be said in general about ecological systems and how they work? If there are generalities in ecology, do they take the form of exceptionless “laws of nature” analogous (...) to the laws of physics? Or do they take some other form? Should ecologists even try to identify ecological generalities? If so, how? The variety of nature is matched by the variety of ecologists’ answers to those questions. I will suggest that all of their answers are right—sometimes. Here I propose a taxonomy of the many different “roads to generality” in ecology: the various different kinds of “generality” that ecologists seek. I argue that each road to generality is valuable in its own way, but that different roads are useful in different contexts and for different purposes. Different roads to generality thus can be complementary to one another, and it would be a mistake for the field of ecology as a whole to focus exclusively on any one of them. (shrink)

The present article discusses different basic semiotic-scientific postulates regarding mammals’ sign activity. On the one hand, there are arguments denying animals sign activity, according to which mammals are not capable of semantic generalization on the basis of conventional linguistic values. According to another approach, mammals’ sign activity can be considered as means of ecological adaptation, that is, the features of animal behaviour based on the information, received by them through their habitat characteristics without direct visual contacts with their kind. (...) Movement elements, behavioural reactions of similar motivation and parameters of the sign field, which represents an animal’s sign-information environment, may have some numerical expression and can becalculated depending on the research tasks. Formalization of the animal activity implies simultaneous consideration of the following parameters: magnitude,intensity, anisotropy and the value of a given sign object. (shrink)

This book argues that philosophy is as practical as plumbing and what we need right now is what philosophers can offer as philosophers to help us all, our species, and beyond, through this ecological emergency, this climate change, this anthropocene. This book is about the meaning and purpose of philosophy as a way of, a practice of, responding to the ecological emergency, which includes climate change, biodiversity loss, pollution, habitat destruction, and all the associated impacts that fragment, and threaten (...) to create collapse, among the systems that created and sustain us. There are the related economic and social impacts, the fragmentation of communities and political ideologies through attitude polarisation, and the increasing threats to systems by those who seek to promote further exploitation at the expense of attempts to regain some system of cooperation and an attitude of compassion which is at the heart of our survival strategies as a species. Philosophy has always sought to address questions related both to our place in the universe, and to how to live, given our understanding of our place. Those of us committed to a philosophical life have used a range of metaphors and narratives to enlighten, and to exhort to action, those who would seek to understand what to do, how, and why. Philosophy has played a key role in helping us as a species to respond to the ecological emergency. What, then, is the practice of philosophy, given that we’re in an ecological emergency? This question is the thread, and it forms the framework for the dialogue that runs through the book. (shrink)

The analysis of genetic and epigenetic mechanisms of the genotype–phenotypic connection has, so far, only been possible in a handful of genetic model systems. Recent technological advances, including next‐generation sequencing methods such as RNA‐seq, ChIP‐seq and RAD‐seq, and genome‐editing approaches including CRISPR‐Cas, now permit to address these fundamental questions of biology also in organisms that have been studied in their natural habitats. We provide an overview of the benefits and drawbacks of these novel techniques and experimental approaches that can now (...) be applied to ecological and evolutionary vertebrate models such as sticklebacks and cichlid fish. We can anticipate that these new methods will increase the understanding of the genetic and epigenetic factors influencing adaptations and phenotypic variation in ecological settings. These new arrows in the methodological quiver of ecologist will drastically increase the understanding of the genetic basis of adaptive traits – leading to a further closing of the genotype–phenotype gap. -/- .

Bradley succeeded in conceptualizing biological productivity in terms—monetary investment vs. profit—that could be applied to organisms as different in form and habitat as trees, grapevines, and crayfish.41 This form of measurement was not precise enough to have served as a basis for actual comparisons of production rate. His way of thinking, however, could have been applied with other terms of measurement once the usefulness of such measurements had been realized. The realization that production rate is an important factor is (...) implicit in his discussions, but for his purposes, yearly yields were generally sufficiently precise determinations.Although Bradley drew substantially upon the contributions of others, his writings represent a significant beginning for productivity ecology. All of the kinds of investigations that he reported could have been extended, rendered more precise, and formed the basis of ecological generalizations during the eighteenth century.There were, however, certain conceptual limitations imposed by a lack of relevant knowledge in physiology and in physical science. A good understanding of productivity ultimately depends upon an understanding of metabolism, which in turn depends upon an understanding of photosynthesis, respiration, biochemistry, and the first and second laws of thermodynamics. The essential knowledge of these subjects would not be available until decades after Bradley's time. (shrink)

Both landscape and aesthetics are all too often considered disengaged categories associated with leisure and contemplation. This book establishes landscape as a key concept in contemporary thought and rethinks aesthetics in political and activist terms. In order to do so, it challenges the dualism of "the environment" as the space inhabited by humans and the province of the natural sciences about which philosophy has little to say. (This separation is evident even in the name of the recent field of environmental (...) humanities.) In a holistic view, landscapes are at the intersection of environment and human, place and people, and nature and culture, and aesthetics provide an immersive and engaged approach to them. Landscapes are ways of being in the world and aesthetics practical means of inhabiting them. Utilizing a pragmatist, antiessentialist lens, Alberto L. Siani characterizes landscapes (as opposed to environments and territories) as concrete, experienced habitats, performative ways of making sense of the world, while aesthetics (following Dewey) identify values and ordering criteria that permeate them. He addresses issues such as temporality, environmentalism, justice, education, and interdisciplinarity within this framework and in conversation with scientific positions. A coda gives three phenomenological accounts of intensely experienced and inhabited landscapes. (shrink)

This book explores the moral, social, and spiritual dimensions of ecological restoration. Gretel Van Wieren, a religion scholar, builds on the work of both critics and advocates of restoration to develop a balanced and well-informed approach to a controversial topic in environmental ethics. Ultimately she finds much value in restoration, as much for its ability to help build human community as for its contributions to ecological well-being. Restoration, she summarizes, is “the attempt to heal and make the human relationship to (...) nature whole” (2).While she holds a generally positive view of restoration, Van Wieren consistently faces the ambivalence inherent in human efforts to recreate wild habitats. Restorationists are faced, as she explains, with “the simultaneous realities that they are in some sense making up nature as they go… and that natural processes are in some sense other than and beyond the human mind” (20). By keeping both these dimensions in mind, Van Wieren presents a balan. (shrink)

Rendell and Whitehead argue persuasively that individual foraging specializations, if socially learned, are examples of cetacean culture. However, they discount ecological variation experienced by individuals within a population as a factor in such behavior. I suggest that ecological variation may play an important role in individual foraging specializations and describe several ecological parameters that may help us understand the high frequency of this interesting behavior in the marine habitat.

We propose the beginnings of a general theory of environments, of the parts or regions of space in which organisms live and move. We draw on two sources: on the one hand on recent work on the ontology of space; and on the other hand on work by ecological scientists on concepts such as territory, habitat, and niche. An environment is in first approximation a volume of space; it is a specific habitat, location, or site that is suitable (...) or adequate for given purposes (of foraging, resting, hunting, breeding, nesting, grooming) in the life of an organism or group of organisms. This spatial notion of environment can be drawn closer to biological and ecological science by taking account of the pertinent physical attributes realized within given spatial regions. (shrink)

Mongolian traditional botanical knowledge has been rarely researched concerning the ethnobotany theory and methodology in the last six decades ). However, most of the known literature of indigenous knowledge and information regarding the use of local wild plants among Mongolian herders was first documented by several botanical research of Russian researchers in Mongolia through the 1940s and 1950s. One of the most comprehensive works was completed by A. A. Yunatov, which is known as “Fodder Plants of Pastures and Hayfields of (...) the People’s Republic of Mongolia”. Yunatov’s research sampled forage plants in Mongolia from 1940 to 1951 and subsequently published a study in 1954. The original transcript of FPM was later translated into Chinese and Mongolian during 1958 and 1968. In addition to morphological characteristics, distribution, habitat, phenology, palatability, and nutrition of forage plants, Yunatov`s record collected local names, the folk understanding and evaluation of the forage, as well as other relevant cultural meanings and the use of local wild plants in FPM through interviews. The book contains the most precious records created in the 1940s and 1950s on folk knowledge of the Mongolians' wild plants in Mongolia. It was composed of 8 chapters and 351 pages in total. The fifth chapter of FPM, entitled “The systematic overview of forage plants,” making up 272 pages. The order and content of the book-oriented along with profiles of specific plants. Yunatov collected detailed information on plants, such as the local name, morphology, distribution, habitats, ecological characteristics, and phenology. He also discussed the palatability of livestock, particular forage use, other usages, and chemical composition. Through careful reading and understanding of all three versions of the book ), the FPM-listed information of edible plants was categorized using ethnobotanical dependent analysis. The list of edible plants was ranked based on purposes and ethnobotanical inventories as per methodology and analysis used in the ethnobotany research. FPM listed 35 species are part of 15 families and 25 genera of wild edible plants. Most species belong to Liliaceae and Allium. Naturally grown grain and some food substitutes come from the starchy organs, such as seeds, bulbs, roots, and rhizomes of 12, accounting for 34.28% of all species. Wild vegetables come from the parts of a young plant, tender leaves, young fruits, lower leg of stems, and bulbs of 9 species, accounting for 25.71% of all species. There are only three species of wild fruits, accounting for 8.57% of all edible plant species. Tea substitutes consist of leaves, roots, follicle, and aboveground parts of 8 wild plant species, accounting for 22.85% of all species. Seasonings from the wild were made of the elements such as seeds, rhizomes, tender leaves of 7 species, accounting for 20.00% of all species. Similarities and differences are noticeable in utilizing wild edible plants among Mongolian populations living in Mongolia and Inner Mongolia. Six species of wild edible plants listed in FPM have been proven to be collected and consumed by Mongolians from the Genghis Khan era in the twelfth century to the present day. This proved that the Mongolians have a tradition of recognizing and utilizing wild plants, demonstrating historical and theoretical value. Seven species of plants mentioned in this book were closely correlated to the locals' processing of traditional dairy products, meat, and milk food. Yunatov was not an ethnobotanist, but his accurate documentation of interviews and surveys with Mongolians represents valuable information about the collection and consumption of local wild plants during 1940–1951 in Mongolia. His research mission meant to focus on forage grass, the feed plant that sustained livestock, while he also recorded plants consumed by humans. His records on the edible parts and intake methods of some plants are incomplete. Still, it provided ethnobotanical materials of a remarkable scientific value and a living history of ethnobotany in Mongolian regions. Even by today`s standards, it will be challenging to obtain first-hand information of the richness and to the extent of Yunatov’s research. (shrink)

Spirituality connotes praxis informed by religious or faith convictions. This can transform the individual and society at large. Christian spirituality is centered on how a person’s relationship with the God of Jesus Christ informs and directs one’s approach to existence and engagement with the world. The ecosystem concerns humanity and relationship with it is invariably influenced by faith or religious informed praxis. The reality of climate change is convincing many people that humankind’s common homeland needs to be treated with care (...) and respect if created beings are to have a congenial habitat now and in the future. This article avers that Christian spirituality can contribute to eco-friendly behavior through re-formation of the behavior of people and emboldening their goodwill as regards the responsibility of all towards the care of the earth. Finally, this research proffers a three-fold model of eco-spirituality - scriptural, selfcontrol, and sacramental approaches to the earth – as a contribution towards stemming the tide of ecological assaults on creation. Textual analysis is the method used in this research. (shrink)

Despite their diversity and ecological importance, many areas of the SAR—Stramenopila, Alveolata, and Rhizaria—clade are poorly understood as the majority of SAR species lack molecular data and only 5% of species are from well-sampled families. Here, we review and summarize the state of knowledge about the three major clades of SAR, describing the diversity within each clade and identifying synapomorphies when possible. We also assess the “dark area” of SAR: the morphologically described species that are missing molecular data. The majority (...) of molecular data for SAR lineages are characterized from marine samples and vertebrate hosts, highlighting the need for additional research effort in areas such as freshwater and terrestrial habitats and “non-vertebrate” hosts. We also describe the paucity of data on the biogeography of SAR species, and point to opportunities to illuminate diversity in this major eukaryotic clade. See also the video abstract here: https://youtu.be/_VUXqaX19Rw. Despite their diversity, abundance, and importance, fewer than 10% of the species within the SAR—Stramenopila, Alveolata, and Rhizaria—clade have been assessed using molecular tools. Only a small percentage of the molecular records contain information on ecology or have associate location data, indicating a tremendous dark area. (shrink)

The concept of niche (setting, context, habitat, environment) has been little studied by ontologists, in spite of its wide application in a variety of disciplines from evolutionary biology to economics. What follows is a first formal theory of this concept, a theory of the relations between objects and their niches. The theory builds upon existing work on mereology, topology, and the theory of spatial location as tools of formal ontology. It will be illustrated above all by means of simple (...) biological examples, but the concept of niche should be understood as being, like concepts such as part, boundary, and location, a structural concept that is applicable in principle to a wide range of different domains.

Darwin's theory of evolution brought to an end the static view of nature. It was no longer possible to think of species as immortal, with secure places in nature. Fluctuation of population could no longer be thought of as occurring within definite limits which had been set at the time of creation. Nor was it any longer possible to generalize from the differential reproductive potentials, or from a few cases of mutualism between species, that everything in nature was “fitted to (...) produce general ends, and reciprocal uses.” 134 The appeal to “design” could no longer be substituted for answers to questions concerning animal demography. Instead, the dynamics of a population had to be viewed as the outcome of species' struggle against animate and inanimate factors in the environment. Both the members of a species and the environmental factors tend to vary randomly, and therefore neither evolution nor population dynamics could be fully understood alone. For this reason Darwin's linking of the two subjects was inevitable and not merely an historical accident. Since Darwin had shown that no automatic equilibrium existed, he demonstrated the importance of closer study of the causes of population dynamics and extinction. He also indicated that an understanding of population depends upon the development of a broad knowledge in ecology.Viewed from another direction, Darwin's work ended the early modern era of population studies by clarifying three interrelated problems which were important for understanding population: extinction, distribution, and the nature of species. The components of his answer had been discussed in the eighteenth century, but there had not existed enough evidence for the completion of the revolution in thought which had then begun. At the beginning of the nineteenth century, Playfair found the evidence for extinction conclusive, and, in spite of Lamarck, Curvier convinced the scientific world that there could no longer be any doubt about it. This was a step the importance of which, with his limited knowledge of biogeography and population, Cuvier could not have fully realized. Lamarck attempted, with his evolutionary theory, to circumvent the necessity for admitting extinction, but he overestimated the adaptability of organisms and in doing so he underestimated the importance of competition and the whole field of ecology. On the other hand, he was not willing to let questions such as the origin of species remain taboo to science. The origin of species was a biogeographical as well as a paleontological question. Humboldt correlated environment with the distribution of species and conveyed the impression that plant communities are subject to change. De Candolle, following the lead of Linnaeus and Humboldt, emphasized the ecological aspects of biogeography, not only the importance of habitat and range, clearly showing the ecological effects of competition. The entomologists Kirby and Spence took a faltering step toward understanding the relationship between population and ecological role, but they fell short of any significant new conclusions. Neither they nor Swainson could fully comprehend the new perspective of De Candolle.Lyell was able to bring together the evidence from these three lines of investigation and weave them into an important synthesis that almost accomplished that Darwin later did. Although opposing Lamarck's theory of evolution, Lyell had a dynamic view of ecology. He realized that population dynamics offered an important key to the understanding of biogeography. Since he knew that species become extinct, he investigated closely the factors which could either preserve or extinguish species. While explaining these factors, he described the interrelationships of species in greater detail than had ever been done before. Forbes continued to develop Lyell's ecological concepts, and his first-hand field experience enabled him to describe biotic communities more concretely than Lyell had.Having the advantages of Lyell's understanding and his own experience from a global voyage, Darwin could take the final step from the static to the dynamic concept of life. He had seen populations fluctuating and also fossil species in South America, and on the Galapagos Islands he had encountered a biogeographical problem that could not be credibly solved without the idea of evolution. However, the bare idea of evolution did not fully answer his questions. He sought physiological causes of extinction before he read Malthus and realized that De Candolle and Lyell had correctly emphasized the importance of competition. Darwin found that, in order to understand evolution, he needed to improve his understanding of ecology. He wanted to know when populations were most easily decimated, how extensive were competition and cooperation, what effects parasites have upon populations, and what changes occur in biotic communities when a species is either added or subtracted. He contributed to some extent to answering these questions. Though there remained much for others to do, there was now a new and more secure theoretical framework within which later studies could be interpreted. As Ernst Mayr has observed, Darwin's “consistent thinking in terms of population has had an impact on biological theory and practice which is second only to his sponsorship of natural selection as the mechanism of evolution.” 135.

Understanding ecological boundaries is recognized by ecologists as important for understanding ecosystem dynamics. All borders are borders in relation to some organism. However, much of the literature on habitat change ignores this basic ecological fact. In addition, borders are highly influenced by accidental or historical features of ecosystems, and researchers have in many cases defined them only in terms of convenience. Several viewpoints explored in this article reflect this skepticism about identifying ecosystems as real structured entities. I draw on (...) Ghiselin’s hypothesis that species are not natural kinds but individuals, to develop a relational approach to ecological boundaries. I argue that with regard to ecology a border is always a border for a specific organism, and is a border in a specific manner for that organism. I draw on studies of two species of tsetse fly found in the Mauhoun river basin in Burkina Faso to illustrate why this relational approach is important. This approach may also help identify weaknesses in conservation efforts that have not properly asked the question, “Boundary for what?”. (shrink)

Urban infrastructures serve as the backbone of modern economies, mediating global exchanges and responding to urban demands. Yet, our comprehension of these complex structures, particularly within diverse socio-political terrain, remains fragmented. In bridging this knowledge gap, this study delves into “boundary objects”—entities enabling diverse stakeholders to collaborate without a comprehensive consensus. Central to our investigation is the hypothesis that oceanic infrastructural developments are instrumental in molding the interface of urban, industrial, and energy sectors within marine contexts. Our lens is directed (...) at the Gulf of Mexico, which is distinguished by its industrial depth and expansive marine grid. We highlight the Gulf Intracoastal Waterway’s (GIWW) paramount role in regional movement and the ecological facets of practices such as dredging, which is vital for transport and coastal conservation. A striking revelation of our study is the transformation of offshore structures in the Gulf into vibrant marine habitats. Emphasizing the intertwined nature of marine infrastructures, we denote oceans as pivotal platforms for impending urban expansion, especially as land resources wane. Our research aspires to validate the role played by oceans as a nexus in the urban–industrial–energy fusion. (shrink)

Habitat dioramas depicting ecological relations between organisms and their natural environments have become the preferred mode of museum display in most natural history museums in North America and Europe. Dioramas emerged in the late nineteenth century as an alternative mode of museum installation from taxonomically arranged cases. We suggest that this change was closely connected to the emergence of a biogeographical framework rooted in evolutionary theory and positing the existence of distinct biogeographical zones. We tie the history of dioramas (...) to earlier visual resources such as the thematic images that Wallace introduced to illustrate his 1876 Geographical Distribution of Animals. These images were unique in their time because each of them simultaneously depicted animals from several different taxa, rather than only one, as well as the ecological relations between animals and their habitats. Both, visually and with respect to their function within biogeography, these images presaged the habitat dioramas that came shortly afterwards. Not coincidentally, Wallace explicitly advocated the use of dioramas for museum display in ongoing debates on museum reform. Wallace 's suggestions were put into practice by committed evolutionists such as Gottlieb von Koch who pioneered the diorama installation in the Grand Ducal Museum in Darmstadt in 1906. As in Wallace 's illustrations, Koch's dioramas were designed to respresent biogeographical zones. This paper explores the function of these visual displays of biogeographical relations. It argues that, in both the scientific and public realms, biogeogaphical zones were defined and constructed by visual means; recourse to visual representation was more than a method of communication.
