Evidence that humans play a dominant role in most ecosystems forces scientists to confront systems that contain factors transgressing traditional disciplinary boundaries. However, it is an open question whether this state of affairs should encourage interdisciplinary exchange or integration. With two case studies, we show that exchange between ecologists and economists is preferable, for epistemological and policy-oriented reasons, to their acting independently. We call this “exchange gain.” Our case studies show that theoretical exchanges can be less disruptive to current theory (...) than commonly thought. Valuable interdisciplinary exchange does not necessarily require disciplinary breakdown. (shrink)

While no one denies that science depends on epistemic values, many philosophers of science have wrestled with the appropriate role of non-epistemic values, such as social, ethical, and political values. Recently, philosophers of science have overwhelmingly accepted that non-epistemic values should play a legitimate role in science. The recent philosophical debate has shifted from the value-free ideal in science to questions about how science should incorporate non-epistemic values. This article engages with such questions through an exploration of the environmental sciences. (...) These sciences are a mosaic of diverse fields characterized by interdisciplinarity, problem-orientation, policy-directedness, and ubiquitous nonepistemic values. This article addresses a frequently voiced concern about many environmental science practices: that they ‘crowd out’ or displace significant non-epistemic values by either (1) entailing some non-epistemic values, rather than others, or by (2) obscuring discussion of non-epistemic values altogether. With three detailed case studies e monetizing nature, nature-society dualism, and ecosystem health e we show that the alleged problem of crowding out emerges from active debates within the environmental sciences. In each case, critics charge that the scientific practice in question displaces nonepistemic values in at least one of the two senses distinguished above. We show that crowding out is neither necessary nor always harmful when it occurs. However, we do see these putative objections to the application of environmental science as teaching valuable lessons about what matters for successful environmental science, all things considered. Given the significant role that many environmental scientists see for non-epistemic values in their fields, we argue that these cases motivate lessons about the importance of value-flexibility (that practices can accommodate a plurality of non-epistemic values), transparency about value-based decisions that inform practice, and environmental pragmatism.

Recently, invasion biologists have argued that some of the skepticism expressed in the scientific and lay literatures about the risks of invasive species and other aspects of the consensus within invasion biology is a kind of science denialism. This paper presents an argument that, while some claims made by skeptics of invasion biology share important features with paradigm cases of science denialism, others express legitimate ethical concerns that, even if one disagrees, should not be dismissed as denialist. Further, this case (...) illustrates a more general point about ethical disagreement within sciences like invasion biology that constitutively pursue non-epistemic goals and values. While philosophers of science have argued that epistemic disagreement within science can be productive as heterogeneous epistemic communities “hedge their bets,” the case of invasion biology shows how non-epistemic or ethical disagreement within sciences, while carrying significant risks, can also be epistemically and non-epistemically valuable.

In this paper I argue that the value attributed to coral reefs drives the characterisation of evidence for their regeneration or degradation. I observe that regeneration and degradation depend on an understanding of what an ecosystem looks like when undegraded (a baseline), and that many mutually exclusive baselines can be given for any single case. Consequently, facts about ecological processes are insufficient to usefully and non-arbitrarily characterise changes to ecosystems. By examining how baselines and the value of reefs interact in (...) coral and algal reef examples, I argue that considering the value of an ecosystem is a necessity when describing processes like regeneration and degradation. This connects value as studied in socio-ecological and economic research with values as discussed in the philosophy of science literature. It also explains why such a broad range of processes may be considered regenerative, including those which introduce significant novelty, as well as pointing towards ways to mediate related debates, such as those surrounding novel and ‘pristine’ ecosystems.

Classifying species as ‘native’ or ‘alien’ carries prescriptive force in the valuation and management of ‘nature’. But the classification itself and its application are contested, raising philosophical and geographical questions about place, space, rights, identity and belonging. This paper discusses leading critiques of the native/alien paradigm, including its conceptual fluidity, dichotomous rigidity and ethical difficulties, as well as the incendiary charge of xenophobia. It argues that valorizing ‘native nature’ as inherently the ‘best nature’ is not only obsolete but impracticable in (...) the Anthropocene, and that the preeminence of biogeographic origins should be replaced with a pragmatic focus on species’ behavior.

In this article I discuss the proposition that ecologists may place restrictions on the kinds of plants and animals and on the kinds of systems they consider relevant to assessing the resiliency of ecological generalizations. I argue that to restrict the extension of ecological science and its concepts in order to exclude cultivated plants, captive animals, and domesticated environments ecologists must appeal either to the boundaries of their discipline; to the idea that the effects of human activity are rare and (...) unusual enough to count as ceteris paribus conditions; or to the nature/culture divide. The boundaries of their discipline, however, are practical, not epistemological. The effects of human activity are ubiquitous and profound. And the nature/culture divide, as far as I know, has been infra dignitatem in the natural sciences at least since Charles Darwin and John Stuart Mill. Ecologists may reason, moreover, that organisms and systems that have the kind of history that interests them must as a result possess a kind of organization or some other general biological property that distinguishes them from those that do not. This is to commit a genetic fallacy. (shrink)

The relationship of man himself to his environment is an inseparable part of ecology; for he also is an organism and other organisms are a part of his environment. Ecology, therefore, broadly conceived and rightly understood, instead of being an academic science merely, out of touch with humanistic interests, is really that part of every other biological science which brings it into immediate relation to human kind. The proper place of humans in ecological study has been a recurring issue for (...) ecology. Of course humans are part of Nature writ large, but are they part of the ecologist's nature? The question bothered biologists even before the discipline of ecology was firmly institutionalized.... (shrink)
