Mobile health services have been widely used in medical services and health management through mobile devices and multiple channels, such as smartphones, wearable equipment, healthcare applications, and medical platforms. However, the number of the users who are currently receiving the mHealth services is small. In China, more than 70% of internet users have never used mHealth services. Such imbalanced situation could be attributed to users’ traditional concept of medical treatment, psychological factors and privacy concerns. The purpose of this study is (...) to explore the direct and indirect effects of mHealth users’ self-efficacy and privacy concerns on their intention to adopt mHealth services, providing guidelines for mHealth service providers to enhance users’ intention of adoption. A questionnaire was designed by the research team and 386 valid responses were collected from domestic participants in China. Based on the unified theory of acceptance and use of technology model, a research model integrated self-efficacy and privacy concerns was constructed to investigate their effects on users’ intention to adopt mobile mHealth services. The results show that self-efficacy could facilitate users’ intention to adopt mHealth services, and had a significantly positive effect on perceived ubiquity, effort expectancy, performance expectancy and subjective norm. This study verifies the direct and indirect effects of self-efficacy and privacy concerns on users’ intention to adopt mHealth services, providing a different perspective for studying mHealth adoption behavior. The findings could provide guidelines for mHealth service providers to improve their service quality and enhance users’ intention of adoption. (shrink)

It is hypothesized that iron from biological tissues, liberated during decay, may have played a role in inhibiting loss of anatomical information during fossilization of extinct organisms. Most tissues in the animal kingdom contain iron in different forms. A widely distributed iron‐bearing molecule is ferritin, a globular protein that contains iron crystallites in the form of ferrihydrite minerals. Iron concentrations in ferritin are high and ferrihydrites are extremely reactive. When ancient animals are decaying on the sea floor under anoxic environmental (...) conditions, ferrihydrites may initialize the selective replication of some tissues in pyrite FeS2. This model explains why some labile tissues are preserved, while other more resistant structures decay and are absent in many fossils. A major implication of this hypothesis is that structures described as brains in Cambrian arthropods are not fossilization artifacts, but are instead a source of information on anatomical evolution at the dawn of complex animal life.

It is necessary to complement next‐generation sequencing data on the soil resistome with theoretical knowledge provided by ecological studies regarding the spread of antibiotic resistant bacteria (ARB) in the abiotic and, especially, biotic fraction of the soil ecosystem. Particularly, when ARB enter agricultural soils as a consequence of the application of animal manure as fertilizer, from a microbial ecology perspective, it is important to know their fate along the soil food web, that is, throughout that complex network of feeding interactions (...) among members of the soil biota that has crucial effects on species richness and ecosystem productivity and stability. It is critical to study how the ARB that enter the soil through the application of manure can reach other taxonomical groups (e.g., fungi, protists, nematodes, arthropods, earthworms), paying special attention to their presence in the gut microbiomes of mesofauna‐macrofauna and to the possibilities for horizontal gene transfer of antibiotic resistant genes.

Dispersal of biota by humans is a hallmark of civilization, but the results are often unforeseen and sometimes costly. Like kudzu vine in the American South, some examples become the stuff of regional folklore. In recent decades, "invasion biology," conservation-motivated scientists and their allies have focused largely on the most negative outcomes and often promoted the perception that introduced species are monsters. However, cases of monstering by scientists preceded the rise of popular environmentalism. The story of tamarisk (Tamarix spp.), (...) flowering trees and shrubs imported to New England sometime before 1818, provides an example of scientific "monstering" and shows how slaying the monster, rather than allaying its impacts, became a goal in itself. Tamarisks' drought and salt tolerance suggested usefulness for both coastal and inland erosion control, and politicians as well as academic and agency scientists promoted planting them in the southern Great Plains and Southwest. But when erosion control efforts in Arizona, New Mexico and Texas became entangled with water shortages, economic development during the Depression and copper mining for national defense during World War Two, federal hydrologists moved quickly to recast tamarisks as water-wasting foreign monsters. Demonstrating significant water salvage was difficult and became subsidiary to focusing on ways to eradicate the plants, and a federal interagency effort devoted specifically to the latter purpose was organized and continued until it, in turn, conflicted with regional environmental concerns in the late 1960s.

Veit suggests that the challenge of coordinating movement in multicellular organisms led to the evolution of a prioritizing value system, which rendered organisms complex enough to be sentient and drove the Cambrian explosion, while the absence of this evaluation system led to the demise of Ediacaran animals. In this commentary we criticize Veit’s terminology and evolutionary proposals, arguing that his terminology and evolutionary scenarios are problematic, and put forward alternative proposals. We suggest that sentience is a system property, and that (...) the evolution of sentience was the outcome of the evolution of open-ended associative learning, which included the coevolution of sensory, motor, memory, and value subsystems. We suggest that these coevolutionary system dynamics were a factor in the Cambrian explosion and contributed to the extinction of the Ediacaran biota. (shrink)

Contrary to frequent characterisations, exotic species should not be identified as damaging species, species introduced by humans, or species originating from some other geographical location. Exotics are best characterised ecologically as species that are foreign to an ecological assemblage in the sense that they have not significantly adapted with the biota constituting that assemblage or to the local abiotic conditions. Exotic species become natives when they have ecologically naturalised and when human influence over their presence in an assemblage (if (...) any) has washed away. Although the damaging nature and anthropogenic origin of many exotic species provide good reasons for a negative evaluation of such exotics, even naturally-dispersing, nondamaging exotics warrant opposition. Biological nativists' antagonism toward exotics need not be xenophobic and can be justified as a way of preserving the diversity of ecological assemblages from the homogenising forces of globalisation. Implications for Yellowstone National Park policy are explored. (shrink)

Progress has become a suspect concept in evolutionary biology, not the least because the core concepts of neo-Darwinism do not support the idea that evolution is progressive. There have been a number of attempts to account for directionality in evolution through additions to the core hypotheses of neo-Darwinism, but they do not establish progressiveness, and they are somewhat of an ad hoc collection. The standard account of fitness and adaptation can be rephrased in terms of information theory. From this, an (...) information of adaptation can be defined in terms of a fitness function. The information of adaptation is a measure of the mutual information between biota and their environment. If the actual state of adaptation lags behind the state of optimal adaptation, then it is possible for the information of adaptation to increase indefinitely. Since adaptations are functional, this suggests the possibility of progressive evolution in the sense of increasing adaptation.

Two kinds of factors set the tempo and direction of organic and cultural evolution, those external to biotic evolutionary process, such as changes in the earth’s physical and chemical environments, and those internal to it, such as the time required for chance factors to lead lineages across adaptive valleys to a new niche space (Valentine 1985). The relative importance of these two sorts of processes is widely debated. Valentine (1973) argued that marine invertebrate diversity patterns responded to seafloor spreading as (...) this process generated more or less niche space. He suggested that natural selection is a powerful force and that earth’s biota are in near equilibrium with the niches available on the geological time scale. Walker and Valentine (1984) modeled the evolution of species assuming a logistic speciation rate limited by internal factors and a diversity-independent death rate caused by ongoing environmental change. Fitting this model to the observed evolution of shelled marine invertebrates suggests that the lag between extinctions and the evolution of new species leaves perhaps 30% of ecological niches unfilled. In this model, the biota lag environmental change by perhaps a few million years. However, as Valentine (1985) notes, if adaptive landscapes have whole suites of niches protected by deep maladaptive valleys, the waiting time for some pioneering species to cross the divide may be very long, generating the rare events that set new body plans and generate major adaptive radiations. Eldredge and Gould (1972) and Gould (2002) championed the idea that internal processes such as genetic and developmental constraints, coupled with the complexity of the adaptive landscape, resulted in a highly historically contingent evolutionary process. On Gould’s account, most of the history of life had to do not with a relatively close tracking of a changing environment but with the halting evolutionary exploration a deeply fissured niche space, mostly by rapid bursts of evolution as a fissure was crossed, followed by long periods of stasis..

Published comments by American scientists on Darwin’s evolutionary theory are rather rare in the latter half of the 19th century. Clarence King, the founding director of the U.S. Geological Survey in 1879, and an experienced field geologist, focused on the relation between Darwin’s evolutionary concepts and the larger context of Hutton/Lyell’s uniformitarianism versus Cuvier’s catastrophism in his 1877 paper, “Catastrophism and Evolution.” King knew that the fossil record contains little or no data supporting Darwin’s vision of gradual evolutionary change. Instead, (...) using horse evolution seen in the rocks of the American West, the very example that by the 1920s had become the shining exemplar of gradual evolutionary change, King argued for catastrophic extinction and evolutionary replacement by “plastic” species that were able to survive in modified form as components of the succeeding biota. Though he could not see such change as involving natural selection, in this novel use of the term “plasticity,” there may well be adumbrations of modern evolutionary biology. King’s themes became muted as Americans began to embrace more fully Darwin’s work. But his version of catastrophism never entirely disappeared, especially in paleobiological circles. And it came back in more fully modern form with force beginning with the work of Norman D. Newell on mass extinctions in the mid-20th century—and with that of two of his students: Eldredge and Gould’s “Punctuated Equilibria.” This essay introduces King’s “Catastrophism and Evolution” for the journal’s “Classics in Biological Theory” collection; King’s article is available as supplementary material in the online version of this introduction.

Agriculture occupies 38% of the planet’s terrestrial surface, using 70% of freshwater resources. Its modern practice is dominated by an industrial–productivist discourse, which has contributed to the simplification and degradation of human and ecological systems. As such, agricultural transformation is essential for creating more sustainable food systems. This paper focuses on discursive change. A prominent discursive alternative to industrial–productivist agriculture is regenerative agriculture. Regenerative discourses are emergent, radically evolving and diverse. It is unclear whether they have the potential to generate (...) the changes required to shift industrial–productivist agriculture. This paper presents a literature-based discourse analysis to illustrate key thematic characteristics of regenerative agricultural discourses. The analysis finds that such discourses: situate agricultural work within nested, complex living systems; position farms as relational, characterised by co-evolution between humans and other landscape biota; perceive the innate potential of living systems as place-sourced; maintain a transformative openness to alternative thinking and practice; believe that multiple regenerative cultures are necessary for deeply regenerative agriculture; and depart from industrialism to varying degrees. The paper concludes by reviewing three transformative opportunities for regenerative discourses—discourse coalitions, translocal organising and collective learning. (shrink)

Philosophers have paid little attention to the distinction between conservation and preservation, apparently because they have accepted John Passmore’s suggestion that conservationism is an expression of anthropocentric motives and that “true” preservationism is an expression of nonanthropocentric motives. Philosophers have therefore concentrated their efforts on this distinction in motives. This reduction,however, is insensitive to important nuances of environmentalist objectives: there are a wide variety of human reasons for preserving natural ecosystems and wild species. Preservationist policies represent a concem to protect (...) biological diversity from the simplifying effects of human management and are motivated by the full range of values (consumptive, aesthetic, scientific, and moral) attached to a diverse biota.Conservationists and preservationists differ mainly in their emphasis on resilience measures versus predictability measures of stability, respectively. The distinction between anthropocentric and nonanthropocentric motives loses importance as emphasis is placed on the longest term values humans place on the proteetion of biological diversity.

Can matter, things, nonhuman organisms, technologies, tools and machines, biota or institutions be seen as creative? How does such creativity reposition the visionary activities of humans? This article is an elaboration of such questions as well as an attempt at a partial response. It was written as an editorial for the special issue of the Digital Creativity journal that interrogates the conception of Post-Anthropocentric Creativity. However, the text below is a rather unconventional editorial. It does not attempt to provide (...) an overview of the issue’s theme but, instead, samples it via a particular example. The idea of the issue was to think about post-anthropocentricism by considering (1) agents, recipients and processes of creativity alongside with its (2) purpose, value, ethics and politics. This article addresses the first subtheme by puzzling at the paradoxes of “field learning” and picks at the second by considering the texture of “automated beauty”. Both of these parts use chess for an example. The narrative on chess is intermitted by a section “on creativity” that attempts to contextualize the case-based discussion in the wider context and to consider motivations and implications.

Estimating whether the Earth’s biota is in the middle of a crisis relies heavily on comparisons between present and past data about biodiversity or biodiversity surrogates. Although the past is a crucial source of information to assess the severity of the current biodiversity crisis, substantive conceptual and methodological questions remain about how paleodiversity and biodiversity are to be properly compared. I argue that to justify claims of a current biodiversity crisis is harder than it appears. More precisely, I claim (...) that paleodiversity measurements are incommensurable with contemporary measurements, given the different ways that biodiversity is conceptualized and operationalized. I conclude by proposing three possible ways of overcoming this incommensurability problem. (shrink)

Meat?eating as a human practice has been under ethical attack from philosophers such as Peter Singer and Tom Regan on both utilitarian and deontological grounds. An organicist ethic, on the other hand, recognizes that all life other than the primary producers, the plants, must feed on life. This essay affirms, with many environmental ethicists, the moralconsiderability of biota other than the human, but denies that this enlargement of the moral community beyond Homo sapiens necessarily precludes our eating of meat. (...) First, absolute deontological arguments against meat?eating are disputed, then utilitarian?hedonistic arguments are shown not to be sufficient to require ethical vegetarianism. Both sorts of arguments have strengths, however, that set us on guard against current abuses in the meat?raising and slaughtering industries. If the principle of ?due respect? for beings with different degrees of intrinsic value is honored, then moderate meat?eating under reformed social practices can be seen as licit. Two final problems then require investigation: the problem of dietary justice for poor humans and the problem of ?speciesism?. Dealing with the latter requires discussion of cannibalism and the ethics of humans being eaten by still higher ?aliens? (shrink)

An environmental ethic needs to have an answer to two basic questions: what nature should we care about, and why? A number of proposals have been made about how to answer these questions. In this paper, I consider in detail one such proposal, namely, biological or ecological integrity. Different characterizations of integrity can be found in the literature, but I will treat the following one as paradigmatic. Integrity refers to a property of landscapes that are relatively unmodified by human activity (...) and that have their native biota largely intact.1 By “native biota,” I mean the native plant and animal life in a particular place, and...

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:The Cosmic Common Good: Religious Grounds for Ecological Ethics by Daniel P. ScheidJohn J. FitzgeraldThe Cosmic Common Good: Religious Grounds for Ecological Ethics Daniel P. Scheid new york: oxford university press, 2016. 264 pp. $31.95Published shortly after the first encyclical to focus on the environment (Pope Francis's Laudato Si'), Daniel Scheid's first book is a significant advance in Christian ethics and religious ecology. Scheid argues that resources in (...) Catholic social thought and other religious traditions can move one to an appreciation of a common good that includes the "more than human world" (xiv). In particular, he "aim[s] (1) to extend Catholic social thought ecologically, and (2) to extend Catholic ecological ethics comparatively" (8).The argument begins by broadening the notion of the common good into a "Catholic cosmic common good," which "emphasizes the centrality of God, the goodness of creation, and humanity's dignified and privileged but contextualized role within the story of creation" (32). This vision is then informed by Augustine, Aquinas, and Thomas Berry. Next, Scheid widens solidarity, a virtue that (per John Paul II) involves "commit[ting] oneself to the common good" (86), into "Earth solidarity," which attends to all ecosystems and species, particularly those most impacted by environmental damage. Solidarity cannot be exercised without respecting others' rights, and Scheid contends that these include "Earth rights" of biota, abiota, and ecosystems. Finally, in order to really "test the potential for the cosmic common good as a ground for interreligious ecological ethics" (124–25), he turns to three non-Abrahamic traditions that each support, augment, and challenge elements of his vision. A Hindu dharmic ecology is theocentric and blurs the line between humans and nonhumans, Buddhist traditions are nontheistic and highlight how all are [End Page 197] interrelated, and American Indians (specifically the Lakota) condemn individualism and demonstrate certain advantages of a more spatial (rather than simply temporal) perspective.The Cosmic Common Good covers an impressive range of thought in under two hundred pages of main text. While the argumentation is intricate, the logical ordering of chapters, the repetition of important points, and some vivid examples assist the reader in following along. The case for Earth rights is especially bold and well argued; Scheid considers objections to them and shows that they can be intelligibly grounded (as prima facie and proportionately weighted) in self-governance and creaturely dignity. This is a very promising development in Catholic social thought, as recent key magisterial teachings do not explicitly affirm that animals have dignity (or rights) but limit themselves to the notion that harming animals is "contrary to human dignity" (see Laudato Si', §§ 92, 130, quoting Catechism of the Catholic Church, § 2418).While the book is generally comprehensive, there are a few surprising lacunae. First, although Scheid himself recognizes that "a properly Catholic ecological ethics would certainly not dismiss the centrality of the Bible" (198n16), there is very little reference to it. The author briefly alludes to the Psalms' portrayal of the natural world (47, 181), but more integration of the Old and New Testaments would have been illuminating. And while The Cosmic Common Good makes a commendable last-minute effort to incorporate insights from Laudato Si', Francis's predecessor Benedict XVI (often dubbed "the Green Pope") receives too-short shrift. Benedict's ecological views are referenced only on one page, perhaps because they are somewhat more anthropocentric than the "Earth-centered or cosmos-centered" ethic developed by Scheid (24). Regardless, the former pope's frequent calls for environmental responsibility to the poor, future generations, and animals would surely lend some healthy support to the cosmic common good. But these omissions do not detract much from the merits of this book, which should be read "not as a definitive conclusion but as an invitation to generate greater interreligious dialogue and cooperation on an issue that demands extensive and immediate action" (11). Professional academics, graduate students, and others who are somewhat versed in the sophisticated issues Scheid raises would do well to take up his invitation. [End Page 198]John J.

The intricate appearances produced by various lineages of biota have long been viewed as calling for a rational explanation. Biologists are capable of interpreting still just a relatively small part of the overall range of organismal forms and patterns. In fact, we can explain only those for which we find a functional role. Kalevi Kull’s current initiative, which aims at establishing biosemiotic foundations of aesthetics and introduction of concepts such as semiotic fitting, may help us elucidate various hitherto largely (...) neglected aspects of self-expressive domains of life. Given that organisms are active autonomous agents, I suggest that some cases of semiotic fitting may be facilitated by semiotic co-option, a process where a trait is newly interpreted as meaningful within the umwelt of a living being and further adopted for a particular role. Clarification of connections between semiotic co-option and semiotic fitting may aid our attempts to better understand the role of meaning-attributive processes via which the aesthetic faculties of animate things come into existence.

This article examines a poem in the Kaludayittherapadanavannana which expands on the poem attributed to Kaludayitthera in the Theragatha; the poem in the Kaludayittherapadanavannana did not make it into the final canon. The hypothesis of this paper is that the poem may be a popular Dravidian song adapted to Buddhist use and translated into Pali, and this is the primary reason it was excluded from the canon. This conclusion is based on several factors. 1) The author of the Pali poem (...) was not well versed in the Pali language and made constant mistakes in translation. 2) Gratuitous repetition; the poem itself is not very good poetry, containing the kind of needless repetition one associates with a popular song. 3) 13.4% of the words in the poem are direct lifts from Dravidian words; this compares to only 3.9% of the words in the Theragatha poem itself, of which this poem is an extension. While this does not prove that the source was a Dravidian poem, it raises the probability quite significantly. In addition, this kind of literature—making lists of biota in the natural world for comparison, personification and poetic effect— is common in Dravidian Sangam literature. 4) The poem contains wrong or awkward phrases in Pali which can be better understood as Dravidian imports, and 5) an extensive and growing body of linguistic evidence shows that the adoption of Dravidian terminology into Buddhist thought and practice was not an uncommon occurrence. It has long been assumed that the Buddha spoke more than just Indic languages, and that his oral teachings in Dravidian or Munda languages were lost. Although this poem is probably not in itself a teaching of the Buddha, but a popular Dravidian song adapted for Buddhist purposes, its analysis is the first attempt to show that some Pali transmissions may be adaptations or translations of indigenous languages; the ramifications and conclusions of such a hypothesis, if proven, open up a whole new area of Buddhist studies, i.e., the transmission of the Buddha’s teachings through indigenous, non Indo-Aryan languages.

Postmodernism was not launched by the development of Warholesque pop art in the 1960s, nor was it initiated by the explosive destruction of the Pruitt-Igoe modern housing project of St Louis, Missouri in 1972, or by the commissioning of Jean-Francois Lyotard's work on knowledge in advanced societies by the Quebec government in the late 1970s. Postmodernism began with the publication of a paper entitled `The individualistic concept of plant the association' in 1926 by the plant ecologist Henry Gleason. If we (...) dare to characterize postmodernism, emphases on ideas such as heterogeneity, ephemerality, anti-foundationalism, pluralism, fragmentation, indeterminacy, schizophrenia, chaos, antiformalism, discontinuity, absence, playfulness, irony, localism, anarchy and ontological meaninglessness are the ones that tend to abound. The Gleasonian theory of plant associations can be said to reflect such ideas in the ecological arena. Certainly there is room for, and an expanding professional commitment to, a fully-fledged neo-Gleasonian postmodern approach to natural history in which ecological phenomena are examined using non-determinist, pluralist and local perspectives that reject the foundationalism and unifying approach of modernist science and which posits a view of the Earth's biota highlighting fragmentation, anarchism and non-interaction. Community ecology, as opposed to the unifying and totalizing tendencies of ecosystems ecology, might rightly claim to be the intellectual site of such a postmodern natural history. Often, postmodern studies not only attempt to describe a postmodern phenomenon but act to forge new varieties of postmodernism. It is in this vein that this paper seeks to present a non-anthropocentric form of postmodernism; not by dissolving the dualistic barrier that separates humanity from nature (as many environmentalisms would advocate) but by dissolving humanity and nature.

About 540 million years ago, a rapid radiation of animal phyla radically changed the Earth’s biota in a geological eye-blink. What caused this “Cambrian explosion”? Over the years, paleontologists have pointed to a wide array of different physical mechanisms as the causal “trigger” for the explosion. More recently, some paleontologists have proposed complex causal pathways to which multiple physical mechanisms are said to have contributed. Despite their variety, these answers share an assumption that a single explanation can in principle (...) be constructed that identifies some factor or confluence of factors as the cause of the Cambrian explosion. That assumption is unjustifiable. The Cambrian explosion had multiple causes, and different aspects of the event are best explained by different causes. These different causes cannot, even in principle, be integrated into a single causal explanation. We can learn much about the causes of the Cambrian explosiondor for that matter about any historical eventdbut only by attending more carefully to how we frame our causal questions about the past.

This paper is about “glitters”, one of the sources of primary microplastics, which, in turn, are deemed an emerging source of pollutants affecting the environment. Today, most glitters available on the market are essentially microplastics, as they are made of polyesters and are of a size smaller than 5 mm. The tiny, shiny, decorative and colorful glitters are used in a wide range of products including but not limited to make-up or craft materials, clothing, shoes, bags, ornaments, and various objects. (...) The marketing of micron-sized plastic materials, the environmental risks of which are no longer disputable, as disposable products clearly merits attention. People without substantial knowledge or awareness about microplastics pollution and sources thereof have been consuming these glitter products without giving it a second thought. Given their tasteless, odourless, invisible, durable, and last but certainly not least, ubiquitous characteristics, small microplastics nowadays came to pose a substantial threat for the environment and the biota, as a sneaky and persistent contaminant. Microplastic pollution is a completely anthropogenic one. In this context, the consumers should assume a careful and sensible attitude, and question all their consumption habits. On the other hand, the responsibilities of the manufacturers and regulators are also substantial. For, in the lack of any regulation or sanctions in the context of laws and legislation concerning a global problem, and in a context of scarce awareness on part of the society, the people would continue to buy and consume plastic products like glitters without really thinking about them, for as long as they are supplied to the market.

In modern evolutionary theory, selection acts on particular genes and assemblages of genes that operate through phenotypes expressed in environments. This view, however, overlooks the fact that organisms often alter their environments in pursuit of fitness needs and thus modify some environmental selection pressures. Niche construction theory introduces a reciprocal causal process that modifies natural selection relative to three general kinds of environmental components: abiota, biota (other organisms), and artifacts. The ways in which niche-constructing organisms can construct or modify (...) the components differ. Modification of abiota, for example, may have different consequences from the construction of artifacts. Some changes in abiota may simply be caused by the by-products of metabolisms and activities of organisms. Alternatively, artifacts may be “extended phenotypes” that demonstrate obvious prior “design” and “construction” by organisms in the service of fitness needs. Nevertheless, adaptation should always account for the reciprocity between constructed niches and the living agents that construct them. Looking to well-adapted nature for inspiration for human-built artifacts must account for this reciprocity between phenotype and constructed environment as well as the novel features of human architecture, including frank intentionality of design and novel culturally acquired knowledge.

In the postgenomic era, interactions between organism and environment are central in disciplines such as epigenetics, medical physiology, and immunology. Particularly in the more "applied" medical fields, an emphasis lies on interactions of the organism with other organisms, that is, other living things. There is, however, a growing amount of research investigating the impact of abiotic triggers on the immune system. While the distinction between biota and abiota features heavily in other contexts, its status is not explicit within immunology. (...) Do immunologists distinguish living from nonliving triggers? In this article, I will carve out whether and in which ways the biotic/abiotic distinction operates in immunology. I will look into responses to biotic and abiotic stressors in plant and invertebrate model species and ask how and why they are conceptually separated. I will trace the reasons by investigating the disciplinary situatedness of immune phenomena and the import of vertebrate immunology when conceptualizing immune responses in other model organisms. I will then investigate how the convergence of biotic and abiotic stress responses in plants and invertebrates adds to the recent philosophical programs advocating an ecological perspective on immune systems.

This paper is addressed to recent theoretical discussions of the Anthropocene, in particular Bernard Stiegler’s Neganthropocene (Open Universities Press, 2018), which argues: “As we drift past tipping points that put future biota at risk, while a post-truth regime institutes the denial of ‘climate change’ (as fake news), and as Silicon Valley assistants snatch decision and memory, and as gene-editing and a financially-engineered bifurcation advances over the rising hum of extinction events and the innumerable toxins and conceptual opiates that Anthropocene (...) Talk fascinated itself with—in short, as ‘the Anthropocene’ discloses itself as a dead-end trap…”. The objective of this paper is therefore twofold: (1) to discuss how the Anthropocene is appropriated to certain ideological discourses (paradoxically) to maintain the hegemony of precisely those systems of production that have most accelerated climate change etc.; (2) to consider how the factography of the Anthropocene is exploited in this process to mask the ideological character of industry-aligned “technocratic” environmental management. The paper is not concerned with specific case studies in terms of government and industry policy, or climate science, but rather with the ways in which the discourse of the Anthropocene has been inflected within the humanities and the broader cultural field—that is to say, ideologically, as a system or logic of meaning. How the Anthropocene “means” is, in this respect, a question of some importance. This paper does not attempt to address all the facets of this question, but focuses upon a central “apocalyptic” strain in the discourse of the Anthropocene drawn particularly from Francis Fukuyama’s millennial posthumanism and centred in the question of “sustainability” as catastrophe management—with the risk that real environmental degradation will become an alibi for a revived neoliberalism. In other words, that the critical Earth system transformations that characterise the Anthropocene are themselves commodities, and that the project of their amelioration is in process of defining a future (opportunistic) “crisis” rhetoric with a global political franchise. The ideological import of the Anthropocene stems precisely from the fact that it is planetary and, while catalysed by human agency, independent in its specific behaviour from it. The Anthropocene objectively presents as the contemporary counterpart of the Cold War doctrine of Mutually Assured Destruction and the most compelling argument for a new kind of technological “arms race.” But it also presents as the condition of an emerging ideological discourse which will determine how this race is run. From the discourse on “energy security” to the widespread “security crackdown” on environmental activists across the so-called developed & developing world, the Anthropocene has come to represent the co-option of a scientific factography for the thinly disguised resurgence of “ideological science” of the Fukuyamaesque variety (post-history, post-human). For Fukuyama, the true meaning of “posthuman” is thus the accomplishment of humanity’s historical mission. As the “End of History” designates an end of ideological struggle, so too the dénouement of the Anthropocene and the “ends of man” represent the accomplished purpose of species warfare: dominion, not simply over the world, but over all possible worlds. According to this narrative, science—like technology—must be uniquely at the service of the maintenance of the global order, organised around a universal appeal to “crisis management.” It is precisely for this reason that what calls itself post-human masks the return of an ever-more-apocalyptic Humanism.

Efforts have been dedicated to the understanding of social-ecological systems, an important focus in ethnobiological studies. In particular, ethnobiological investigations have found evidence and tested hypotheses over the last 30 years on the interactions between human groups and their environments, generating the need to formulate a theory for such systems. In this article, we propose the social-ecological theory of maximization to explain the construction and functioning of these systems over time, encompassing hypotheses and evidence from previous ethnobiological studies. In proposing (...) the theory, we present definitions and two conceptual models, an environmental maximization model and a redundancy generation model. The first model seeks to address biota selection and its use by human populations. The second emphasizes how the system organizes itself from the elements that were incorporated into it. Furthermore, we provide the theoretical scenario of plant selection and use from an evolutionary perspective, which explicitly integrates the phylogenetic relationships of plants and human beings.

The potential for genetically modified (GM) crops to threaten biodiversity conservation and sustainable agriculture is substantial. Megadiverse countries and centers of origin and/or diversity of crop species are particularly vulnerable regions. The future of sustainable agriculture may be irreversibly jeopardized by contamination of in situ preserved genetic resources threatening a strategic resource for the world—s food security. Because GM crops are truly biological novelties, their release into the environment poses concerns about the unpredictable ecological and evolutionary responses that GM species (...) themselves and the interacting biota may express in the medium and long term. One of the consequences of these processes may be a generalized contamination of natural flora by GM traits and a degradation and erosion of the commonly owned genetic resources available today for agricultural development. GM plants carrying pharmaceutical and industrial traits will pose even more dangerous risks if released in the environment. (shrink)

In this case the message corresponds to Aldo Leopold's call for "a land ethic [that] changes the role (...) of Homo sapiens from conqueror of the land-community to plain member and citizen of it." People should "respect... fellow-members and also... the community as such." 2 Barbara Kingsolver explains Leopold's key ideas and updates the Land Ethic by showing how it might guide people today. The present paper selectively displays this relationship, and then suggests some pedagogical advantages of fiction.Prodigal Summer tells three interconnected stories that take place from May through July one year in contemporary rural Kentucky. One story features Deanna Wolfe, who has spent the last 25 months working for the U.S. Forest Service in a wilderness area on Zebulon Mountain where she restores trails and impedes illegal hunting. She has just discovered that coyotes have arrived, but so has Eddie Bondo, a handsome man from the West who hates coyotes because they sometimes kill livestock. [End Page 106]Another story features Lusa Landowski and her husband Cole Widener. Lusa is an entomologist who taught at the University of Kentucky before marrying Cole and moving to his family's tobacco farm that adjoins the national forest where Deanna works. Cole dies early in the novel and Lusa tries to save the family farm.Finally, Nannie Rawley is a senior citizen who grows organic apples nearby and has conflicts with her more senior neighbor, Garnett Walker, who wants to kill weeds with chemicals to keep his property looking neat. Garnett's goal is to cross-fertilize chestnut trees to create an American chestnut that is immune to chestnut blight. Ecocentrism, Hunting, the Biotic Pyramid, and Exotic Species Aldo Leopold's Land Ethic is famously holistic and ecocentric. The ecosystem, a holistic entity, has value over and above, and in most cases more than, the value of its individual components. This ecocentric perspective is summed up in the maxim: "A thing is right when it tends to preserve the integrity, stability, and beauty of the biotic community. It is wrong when it tends otherwise" (1970, 262).Ecocentrism explains Leopold's attitude toward hunting. In many passages, such as the October account of hunting ruffed grouse (58-62) and partridge (62-69), Leopold describes the hunt with approval. However, he disapproves of programs to eradicate keystone predators because their elimination impoverishes ecosystems. His classic account, "Thinking Like a Mountain," concerns wolf eradication. He writes, "I thought that because fewer wolves meant more deer, that no wolves would mean hunters' paradise" (138). But he found that wolf eradication harms mountains, that is, ecosystems. I have watched the face of many a newly wolfless mountain, and seen the south-facing slopes wrinkle with a maze of new deer trails. I have seen every edible bush and seedling browsed, first to anaemic desuetude, and then to death. I have seen every edible tree defoliated to the height of a saddle horn.... In the end the starved bones of the hoped-for deer herd, dead of its own too-much, bleach with the bones of the dead sage, or molder under the high-lined junipers. (139-40) Leopold's concept of a biotic pyramid explains why wolf eradication harms ecosystems. According to Leopold, the energy that plants absorb from the sun: [End Page 107]... flows through a circuit called the biota, which may be represented by a pyramid consisting of layers. The bottom layer is the soil. A plant layer rests on the soil, an insect layer on the plants, a bird and rodent layer on the insects, and so on up through the various animal groups to the apex layer, which consists of the larger carnivores.... Proceeding upward, each successive layer decreases in numerical... (shrink)

The Reshaping of Phytogeographical Knowledge as the “Transition zone” Wallacea: An American Expansion Project in the Philippines, 1902–1928. This paper examines the development of a concept that to this day plays an important role in biogeography: the region Wallacea. Focussing on the work of the American tropical botanist Elmer D. Merrill in the Philippines, I argue that his research on the geographical movement and settlement of Philippine plants reflects a shift in the United States’ scientific and cultural understanding of the (...) Pacific area towards a notion of “American tropics”. While inventorying plants for the American administration from 1901 to 1923, the composition of Philippine flora prompted Merrill to question biogeographical regionalization in Wallace's Malay Archipelago. Not being able to situate the Philippine flora within “Asian” or “Australasian” biota, Merrill described the islands as an area of trans‐regional plant migration. Together with the paleontologist Roy E. Dickerson, he later conceptualized the region Wallacea as biogeographical “transition zone” between the Philippines and Australia. In addition to the scientific conceptualization, Wallacea constitutes a space between two biogeographical subregions, whose flora was considered as being part of both, but could not be unambiguously attributed to either of these regions. In this respect, the plants resembled the inhabitants of the United States’ insular overseas territories, who were legally defined neither as aliens nor as citizens. In this sense, Wallacea embodies epistemic as well as geopolitical boundaries, while its case also illustrates some of the ways in which colonial interests in the usability of plants found expression in botanical research during the early period of American overseas expansion.

Advances in analytical understanding of the biosphere’s biogeochemical cycles have spawned concepts of Gaia and noosphere. Earlier in this century, in concert with the Jesuit paleontologist Pierre Teilhard de Chardin, the natural scientist Vladimir Vernadsky developed the notion of noosphere-an evolving collective human consciousness on Earth exerting an ever increasing intluence on biogeochemical processes. More recently, the chemist James Lovelock postulated the Earth to be a self-regulating system made up of biota and their environment with the capacity to maintain (...) a planetary steady state favorable to life. This is the Gaia hypothesis. To many, Gaia and noosphere represent contradictory interpretations of humanity’s relation to planetary ecology. Noosphere emphasizes a free will and obligation to shape the destiny of humanity on Earth through technology and new kinds of social relations. In contrast, Gaia invokes mysterious mechanisms of planetary evolution that lie beyond human control and understanding. I argue that if brought together, noosphere and Gaia can provide a useful symbol for guiding human interventions in global ecology because the contradictions of a nature-centered view of Gaia and a human-centered view of noosphere are coming to be irrelevant with the emergence of an analytical science of the biosphere.

S. Hailwood argues that if political liberals, in the Rawlsian sense, refuse to grant non-human nature anything other than instrumental value, then they may properly be characterised as human chauvinists, but not as inconsistent political liberals. He also argues that political liberals who do grant non-instrumental value to the nonhuman are thereby committed to a form of moral valuation of the abiotic. However, an analysis of what is involved in regarding non-human biota as possessing instrumental value reveals that humans (...) must recognise the existence of interests, needs and desires of those non-human organisms which they wish to treat instrumentally. Given this, political liberalism in its most persuasive form, as articulated by Barry, implies that political liberals are not permitted to decide arbitrarily that non-human biota have only instrumental value. But the crucial role of interests in this argument precludes the attribution of any form of moral value to the abiotic. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Ecological Ethics: An IntroductionDavid Keller (bio)Patrick Curry, Ecological Ethics: An Introduction. Malden, Massachusetts: Polity Press, 2007, 173pages.Were I in Bath having drinks with Patrick Curry, we would have much to agree about. Explaining his choice of title of his book, Ecological Ethics, he rightly points out that the more common descriptor "environmental ethics" presupposes a dualism between human beings and the nonhuman environment—an assumption which is itself anthropocentric (...) (p. 4). For philosophers interested in studying the human/ nonhuman dynamic, the legitimacy of anthropocentrism is itself an open question. Because the word 'ecology' treats humans, as biota, as integral parts of ecological systems, the phrase "ecological ethics" is less presumptuous and hence more accurate. The word 'ecological' also has the benefit of conveying the message that the subject is notgoing to involve extending moral considerability from humans out into the "environment." Instead, ecological systems as the locus of value provide the starting point for the elaboration of ethics (p. 2). For Curry, as for Leopold (1960) and Callicott (1989), "ecological community" is coextensive with the ethical community.To correlate the ethical community with the biotic community within the rubric of "ecological ethics" is nothing novel. Curry's claim that "there is something ancient about an ecological ethic" (p. 7) got me thinking: [End Page 153]prior to Abrahamic monotheism and Greek rationalism, ancient peoples, particularly nomadic hunter-gatherers, probably considered themselves as integral parts of what encompassed them, moving with herds, in concert with meteorological and seasonal changes, seeing themselves as one amongst other living beings. They probably did not see themselves apart from the "environment" as we have learned to do. Then with the advent of agriculture, linear furrows and controlled inundations must have fostered an addictive sense of security from flood and famine. Later, the innovations of industrial civilization further distanced us from the caprice of nature's wild vicissitudes. Yet that comfort comes at the expense of lost awareness of our responsibilities as bioticcitizens. Therefore, Curry says, following Sylvan (1973), we need a new ecological ethic since traditional Western morality "is no longer up to the job" (ibid.).Curry remarks that ethics, cast in this light, is not something "optional," something to be addressed after one's belly is full, debts settled, and lodging secured. Rather, ethics cuts directly to the core of human action, of all human activity (p. 5)—a claim reminiscent of Socrates' exhortation to Thrasymachus that it is no small matter that they are discussing, nothing of less importance than the right way to live one's life (Plato 2005, p. 603).Over the first sips of ale, I would praise him for giving his book a simple and straightforward structure that makes a challenging subject accessible, especially to students. After laying down the groundwork of basic concepts in moral philosophy (chapter 3)—objectivism versus relativism, the problem of the is/ought gap, religious morality and environmental philosophy (domination, stewardship, and managerialism), and virtue and rule-based ethics (chapter 4)—Curry addresses axiology (chapter 5). Are humans the sole locus of value (anthropocentrism), or are there other entities worthy of some sort of moral consideration who themselves do not carry the burden of moral responsibility (zoocentrism, biocentrism, ecocentrism)? Curry answers the latter in the affirmative, arguing that ontological interconnectedness of humans with other living beings within ecological systems discloses that something greater than humanity is the locus of value (p. 46).The most useful part of the book for my students out in Utah would be the middle chapters (6–8) in which Curry casts degrees of nonanthropocentrism [End Page 154]in shades of green. These shades range from light green or "shallow" anthropocentric ethics such Bookchin's Social Ecology (p. 50), Hardin's Lifeboat Ethics (pp. 52–54), and mainstream environmentalism (p. 51), through medium green ethics based on the extension of traditional human-oriented moral philosophy to nonhumans such as Singer's Animal Liberation (pp. 56–59), Regan's Animal Rights (pp. 59–60), and Taylor's Biocentrism (pp. 60–62). Curry proceeds to the dark green ethics of ecocentrism, such as Land Ethics (pp. 65–68), the Gaia Hypothesis (pp. 68–71... (shrink)

Efforts have been dedicated to the understanding of social-ecological systems, an important focus in ethnobiological studies. In particular, ethnobiological investigations have found evidence and tested hypotheses over the last 30 years on the interactions between human groups and their environments, generating the need to formulate a theory for such systems. In this article, we propose the social-ecological theory of maximization to explain the construction and functioning of these systems over time, encompassing hypotheses and evidence from previous ethnobiological studies. In proposing (...) the theory, we present definitions and two conceptual models, an environmental maximization model and a redundancy generation model. The first model seeks to address biota selection and its use by human populations. The second emphasizes how the system organizes itself from the elements that were incorporated into it. Furthermore, we provide the theoretical scenario of plant selection and use from an evolutionary perspective, which explicitly integrates the phylogenetic relationships of plants (or other living resources) and human beings.

In this essay, I build on the article by Soulé that established the foundation for the field of conservation biology. I analyze the presuppositions that have guided the discipline’s ethics in the 30 years since that article first appeared. I argue that conservation biology’s normative postulates introduced a paradigm shift that placed the diversity of the biota instead of the biota itself at the center of its ethics. I show that the ensuing priorities in the valuation of nature (...) entail several contradictions at the ethical level and are justifiable only through scientific postulates. Identifying potential revisions and latent ideological issues in science, I defend the position that such scientific legitimization of conservation measures becomes disputable when this option undermines the ethical status of non-human life. Furthermore, I explain the absence of social feedback regarding conservation measures from the perspective of this shift. I conclude with an invitation to critically rethink the ethical basis of conservation sciences so that these fields may achieve their intention of playing a key role in halting the destruction of nature and in encouraging society’s support.

Ao desenvolver a ciência biológica, o ser humano logrou obter novas variedades de animais e de plantas, a partir das silvestres. Quando as técnicas de engenharia genética se aplicaram a êstes organismos, obtiveram-se êxitos que se traduziram em dezenas de animais e de plantas com modificações genéticas agora hereditárias. Segundo o artigo, da análise bioética dos organismos modificados geneticamente e da sua utilizaçéo surgem várias propostas: 1) o direito do consumidor a ser informado em termos que possa entender acerca da (...) natureza das mudanças genéticas realizadas nos alimentos, 2) o direito do consumidor a decidir livremente se os quer consumir ou não e, 3) os deveres morais e científicos dos cientistas e das indústrias agro-alimentares para demonstrar a inocuidade destes animais e plantas transgénicos para o ser humano, o meio ambiente e a biodiversidade. /// Through the development of biological science, humankind was able to obtain new varieties of animals and plants in a process beginning with the wild species.

Finally, the article also argues in favor of the moral and scientific duties of scientists and food industries to demonstrate that genetically modified foods are not dangerous to human beings or noxious to the environment or biota.

According to Michael Soulé, the debate over whether we should or should not actively manage our nature preserves has driven a deep wedge between “wilderness purists,” who advocate a hands-off approach to nature, and “nature managers,” who want to give nature a helping hand whenever the “fullness of the biota” is under threat. Although both camps share the same formal goal, i.e., preserving “authentic nature,” managers and purists have differing views about what the “authenticity of nature” stands for. By (...) introducing a third way of conceptualizing the authenticity of nature that holds the middle-ground between the authenticity of the purists and the managers—namely, natural areas as authentic relics—a bridge can be found between the two positions. As in the case of heath restorations in Flanders, Belgium, the theory of relics can provide an alternative way in which the concept of authenticity is used when evaluating preservation or restoration projects. Moreover, the conception of natural areas as relics is already tacitly at work within certain preservation and/or restoration practices. A comparison of the theory of relics with Robert Elliot’s anti-restoration thesis as put forward in Faking Nature shows that the theory of relics can, to a large degree, save Elliot’s anti-restorationist’s stance in a world that is waking up to the reality of the “end of nature,” while at the same time softening the rigid rejection of all restorative practices implied in the anti-restoration thesis.

One of the purposes of the research program referred to as “systematic biogeography” is the use of species distributions to identify regions and reconstruct biotic area relationships. The reverse, i.e. to group species according to the areas that they live in, leads to the recognition of chorological categories. Biogeographers, working under these two different approaches, have proposed several terms to refer to groups of species that have similar distributions, such as “element”, “chorotype” and “component”. A historical reconstruction, including semantic observations (...) and philosophical implications, shows that these terms have been used in a variety of senses. The word “component” should not be used in biogeography. The word “element” has been used to identify both a group of species defined according to the biogeographic areas they occupy and a group of species with an assumed shared biogeographic history. It is especially because of the influence of the dispersalist paradigm, which dominated evolutionary thought until the mid-twentieth century, that the second definition has been frequently adopted. The term “element” is therefore ambiguous and its use should always be associated with an explicit definition. The word “chorotype” should be used to define groups of species with similar ranges when no causal assumption is made. The concept of “chorotype,” finally, should not be confounded with other concepts such as distributional pattern, cenocron, horofauna, biota, endemic area, area of endemism, biotic element, and generalized track, which are also discussed in this paper.

Less than 0.1% of pesticides applied for pest control reach their target pests. Thus, more than 99.9% of pesticides used move into the environment where they adversely affect public health and beneficial biota, and contaminate soil, water, and the atmosphere of the ecosystem. Improved pesticide application technologies can improve pesticide use efficiency and protect public health and the environment.

In lieu of an abstract, here is a brief excerpt of the content:Ethics & the Enviornment 6.2 (2001) 119-124 [Access article in PDF] Book Review Eugene Odum: Ecosystem Ecologist and Environmentalis Eugene Odum: Ecosystem Ecologist and Environmentalist. Betty Jean Craige. The University of Georgia Press, Athens, 2001, pp. 226. $34.95. ISBN 0-8203-2281-4 (Hardback) A serendipity initiated this review. A half hour before checking my voice mail and receiving the invitation to write this review, I stood at the University of Georgia (...) Press table at the Association for the Study of Literature and the Environment (ASLE) conference in Flagstaff, Arizona. Picking up Betty Jean Craige's new text, I thought to myself, "This book looks interesting! I'm going to have to read it!" Not only did that wish come true; now I have the opportunity to share my thoughts.Prima facie, it may seem odd to print a review on a biography of a scientific ecologist in an environmental ethics journal. In fact, however, nothing could be more appropriate. The science of ecology is directly relevant--even essential--to the ethics of the environment: the human/nonhuman dynamic is contingent upon the identity of human beings, the essence of natural systems, and the interactive relationship between the two. As an environmental philosopher, it was this realization which directed me to the life sciences. [End Page 119]I recommend that environmental philosophers read Craige's book for at least three reasons. First, as just mentioned, the science of ecology addresses some of the necessary conditions for developing an environmental ethic--the ontology of natural systems and the relationship of biota (including Homo sapiens) with the abiotic environment.Second, and more specifically, Odum is a scientist of special concern to environmental philosophers--not to mention moral philosophers and philosophers of science--with his reticence to take seriously the is/ought (or fact/value) gap first identified by the great David Hume. As is widely known, philosophers and scientists who maintain the existence of such a gap contend that it is logically impossible to derive value-laden statements, such as ethical statements, from value-free statements, such as factual statements. According to this line of reasoning, the only way to move from the observation that human activity is causing species extinction to the imperative PRESERVE SPECIES! is another normative assumption that anthropogenic species extinction is bad. Thus Odum is at loggerheads with Bertrand Russell when the philosopher writes: "... questions as to 'values' lie wholly outside the domain of knowledge. That is to say, when we assert that this or that has 'value,' we are giving expression to our own emotions, not to a fact[.]" Siding with Russell against Odum, many ecologists refrain from making ethical (and hence environmentalist) injunctions.What makes Odum especially fascinating is that he recovered from the hangover of Modernity which numerous scientists and philosophers still suffer from: the inability of moving from descriptive science to prescriptive ethics. As Craige remarks over and over again, Odum moves easi-ly between ecology and environmentalism (p. 64): "His inclusion of human beings in ecosystems turned ecosystem ecologists into environmentalists--that is, advocates of policies and social behaviors protective to the natural environment--erasing the line traditional to Western thought between science and politics" (p. 45. See also p. xvii, p. 41). Odum's attitude marks a major breakthrough for the project of grounding environmental ethics in ecological science.Third, Odum is a great scientist whose work is relevant to a host of other philosophical issues. In our recent book, The Philosophy of Ecology: From Science to Synthesis (University of Georgia Press, 2000), Frank Golley and I struggled not to include a piece by Odum in every section of the book. Odum's work has implications for every area in the philosophy of ecology: the ontology of the ecological entity, the reductionism/holism [End Page 120] debate, the rationalism/empiricism debate, evolutionary ecology, and the relationship of ecology to ethics. In light of my work in the philosophy of ecology and familiarity with Odum's research--not to mention meeting him personally several times--I find several of Craige's statements perplexing.

After laying down the groundwork of basic concepts in moral philosophy (chapter 3)—objectivism versus relativism, the problem of the is/ought gap, religious morality and environmental philosophy (domination, stewardship, and managerialism), and virtue and rule-based ethics (chapter 4)—Curry addresses axiology (chapter 5). Are humans the sole locus of value (anthropocentrism), or are there other entities worthy of some sort of moral consideration who themselves do not carry the burden of moral responsibility (zoocentrism, biocentrism, ecocentrism)? Curry answers the latter in the affirmative, arguing that ontological interconnectedness of humans with other living beings within ecological systems discloses that something greater than humanity is the locus of value (p. 46).The most useful part of the book for my students out in Utah would be the middle chapters (6–8) in which Curry casts degrees of nonanthropocentrism [End Page 154]in shades of green. These shades range from light green or "shallow" anthropocentric ethics such Bookchin's Social Ecology (p. 50), Hardin's Lifeboat Ethics (pp. 52–54), and mainstream environmentalism (p. 51), through medium green ethics based on the extension of traditional human-oriented moral philosophy to nonhumans such as Singer's Animal Liberation (pp. 56–59), Regan's Animal Rights (pp. 59–60), and Taylor's Biocentrism (pp. 60–62). Curry proceeds to the dark green ethics of ecocentrism, such as Land Ethics (pp. 65–68), the Gaia Hypothesis (pp. 68–71... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Ethics & the Enviornment 6.2 (2001) 119-124 [Access article in PDF] Book Review Eugene Odum: Ecosystem Ecologist and Environmentalis Eugene Odum: Ecosystem Ecologist and Environmentalist. Betty Jean Craige. The University of Georgia Press, Athens, 2001, pp. 226. $34.95. ISBN 0-8203-2281-4 (Hardback) A serendipity initiated this review. A half hour before checking my voice mail and receiving the invitation to write this review, I stood at the University of Georgia (...) Press table at the Association for the Study of Literature and the Environment (ASLE) conference in Flagstaff, Arizona. Picking up Betty Jean Craige's new text, I thought to myself, "This book looks interesting! I'm going to have to read it!" Not only did that wish come true; now I have the opportunity to share my thoughts.Prima facie, it may seem odd to print a review on a biography of a scientific ecologist in an environmental ethics journal. In fact, however, nothing could be more appropriate. The science of ecology is directly relevant--even essential--to the ethics of the environment: the human/nonhuman dynamic is contingent upon the identity of human beings, the essence of natural systems, and the interactive relationship between the two. As an environmental philosopher, it was this realization which directed me to the life sciences. [End Page 119]I recommend that environmental philosophers read Craige's book for at least three reasons. First, as just mentioned, the science of ecology addresses some of the necessary conditions for developing an environmental ethic--the ontology of natural systems and the relationship of biota (including Homo sapiens) with the abiotic environment.Second, and more specifically, Odum is a scientist of special concern to environmental philosophers--not to mention moral philosophers and philosophers of science--with his reticence to take seriously the is/ought (or fact/value) gap first identified by the great David Hume. As is widely known, philosophers and scientists who maintain the existence of such a gap contend that it is logically impossible to derive value-laden statements, such as ethical statements, from value-free statements, such as factual statements. According to this line of reasoning, the only way to move from the observation that human activity is causing species extinction to the imperative PRESERVE SPECIES! is another normative assumption that anthropogenic species extinction is bad. Thus Odum is at loggerheads with Bertrand Russell when the philosopher writes: "... questions as to 'values' lie wholly outside the domain of knowledge. That is to say, when we assert that this or that has 'value,' we are giving expression to our own emotions, not to a fact[.]" Siding with Russell against Odum, many ecologists refrain from making ethical (and hence environmentalist) injunctions.What makes Odum especially fascinating is that he recovered from the hangover of Modernity which numerous scientists and philosophers still suffer from: the inability of moving from descriptive science to prescriptive ethics. As Craige remarks over and over again, Odum moves easi-ly between ecology and environmentalism (p. 64): "His inclusion of human beings in ecosystems turned ecosystem ecologists into environmentalists--that is, advocates of policies and social behaviors protective to the natural environment--erasing the line traditional to Western thought between science and politics" (p. 45. See also p. xvii, p. 41). Odum's attitude marks a major breakthrough for the project of grounding environmental ethics in ecological science.Third, Odum is a great scientist whose work is relevant to a host of other philosophical issues. In our recent book, The Philosophy of Ecology: From Science to Synthesis (University of Georgia Press, 2000), Frank Golley and I struggled not to include a piece by Odum in every section of the book. Odum's work has implications for every area in the philosophy of ecology: the ontology of the ecological entity, the reductionism/holism [End Page 120] debate, the rationalism/empiricism debate, evolutionary ecology, and the relationship of ecology to ethics. In light of my work in the philosophy of ecology and familiarity with Odum's research--not to mention meeting him personally several times--I find several of Craige's statements perplexing.
