This paper develops the outlines of a pragmatic, adaptive management-based approach toward the control of invasive nonnative species (INS) through a case study of Kings Bay/crystal River, a large artesian springs ecosystem that is one of Florida’s most important habitats for endangered West Indian manatees (Trichechus manatus). Building upon recent critiques of invasion biology, principles of adaptive management, and our own interview and participant–observer research, we argue that this case study represents an example in which rigid application of (...) invasion biology’s a␣priori imperative to minimize INS has produced counterproductive results from both an ecological and social standpoint. As such, we recommend that INS control in Kings Bay should be relaxed in conjunction with an overall program of adaptive ecosystem management that includes meaningful participation and input from non-institutional stakeholders. However, we also note that adaptive management and INS control are by no means mutually exclusive, in Kings Bay or elsewhere. Instead, we suggest that adaptive management offers a means by which INS control efforts can emerge from—and be evaluated through—ongoing scientific research and participatory dialogue about the condition of specific places, rather than non-contextual assumptions about the harmfulness of INS as a general class.

This article explores protection efforts that have arisen in the New York City metropolitan area around the monk parakeet, a nonnative bird that has achieved a broad distribution outside its native habitat range. In some urban regions in which populations are established, controversy has developed around the parakeets’ use of utility infrastructure and potential impacts on native species and agricultural crops. This case provides an opportunity to explore animal protection rhetoric about nonnative species, an understudied topic, (...) considering the great extent to which species have become established in ecosystems outside their natural ranges and the persistence of public affinity for nonnative plants and wildlife. This article identifies four major frames through which advocates have delivered the birds to public and legal audiences and considers how they have mobilized and handled notions of “nonnative-ness” in their advocacy work.

Assuming that both humans and nonhuman organisms have intrinsic value, the concept of a “death with dignity” should extend to the natural world. Recently, an effort has been undertaken to save the razorback sucker, an endangered species of fish in the Colorado River. Razorback are bred and raised in captivity and transferred to the river only when large enough to survive predation by nonnative fish. While this effort is well-intentioned, there is little chance that the razorback will again (...) live unassisted in the Colorado River. There may be human-centered reasons for saving the razorback. However, just as respecting a person sometimes requires limiting his or her life-sustaining medical treatment, so too respecting the razorback may require removing human assistance with its reproductive cycle.

Our recent paper advocating adaptive management of invasive nonnative species (INS) in Kings Bay, Florida received detailed responses from both Daniel Simberloff, a prominent invasion biologist, and Mark Sagoff, a prominent critic of invasion biology. Simberloff offers several significant lines of criticism that compel detailed rebuttals, and, as such, most of this reply is dedicated to this purpose. Ultimately, we find it quite significant that Simberloff, despite his other stated objections to our paper, apparently agrees with our argument (...) that proposals for alternative management of established INS (i.e., alternatives to minimization/eradication) should not be rejected on an a␣priori basis. We argue that more specific development and application of adaptive approaches toward INS management, whether in Kings Bay or other appropriate case studies, would be facilitated if ecosystem managers and invasion biologists follow Simberloff’s lead on this key point. While Sagoff largely shares (and, indeed, served as a primary source for developing) our general arguments that challenge common moral and scientific assumptions associated with invasion biology, he does question our suggestion that participatory adaptive management provides an appropriate framework for approaching environmental problems in which science and politics are inherently entangled. We attempt to answer this criticism through a brief sketch of what participatory adaptive management might look like for Kings Bay and how such an approach would differ from past management approaches.

Along the way he interviewed professional resource managers and naturalists, biologists, interpreters, conservation agents, engineers, farmers, hunters, fishermen, writers, and many others in an effort to gain a perspective that only people who work with the land - for business or for pleasure - can have." "Shelton describes a range of land-management philosophies and techniques, from largely hands-off, as in state parks, to largely hands-on, as in farming. He also addresses the questions that surround some of the more controversial practices, (...) such as the use of fire for land management and the introduction of nonnative species."--Jacket.

Most restoration projects are designed to approximate the species composition and ecotypes ecologists and historians determine were present in an area at some point in the historical past. In most cases, although somewhat arbitrary, the specific time chosen is based on an understanding of historic species composition and anthropogenic disturbances.Although restoring an area to the estimated, historical vegetation types is widely accepted, the exclusory nature of the restoration process often actively eliminates not just invasive species, but also (...) non-invasive, nonnative species as well as displaced native species. These exclusory activities echo patterns of domination and degradation that led to a need for restoration in the first place. Although the domination present in restoration stems from an earnest desire to repair harms inflicted by human carelessness, it at the same time enforces a human conception of the ideal landscape. Attending to ecofeminist concepts such as inclusivism and pluralism, and embracing their rejection of dualistic thinking and the logic of domination demands an expanded tolerance within the practice of ecological restoration. An expanded ecofeminist conceptualization of restoration, a restorashyn, attempts to reduce the presence of overt human domination of the land. Doing so may ultimately mean that the species composition of an ecofeminist restorashyn will not be purely native, but may instead include a diverse mix of both native and non-invasive, nonnative species.

The long 19th century was a period of many developments and technical innovations in agriculture and animal biology, during which actors sought to incorporate new practices in light of new information. By the middle of the century, however, while heredity steadily became the dominant concept in animal husbandry, some policies related to livestock improvement in Brazil seemed to have been tailored following a climate-deterministic concept established in the mid-18th century by the French naturalist Georges-Louis Leclerc, the Comte de Buffon. His (...) theory of animal degeneration posited, among other things, the necessity of recurrent crossbreeding to preserve animal species living in nonnative environments from climate-induced degeneration. Although largely discredited by the early 19th century, the teachings of the French naturalist seem to have found supporters in a Brazilian program to modernize national agriculture through the application of the natural sciences. Herein I examine the revival of Buffon’s theories in that government-sponsored program to improve animal husbandry and breeding techniques, including actual applications of this theory in the real world. Ultimately, I argue that Buffon’s theory of degeneration was used to tailor public policies and funding for the improvement of domesticated animals in Brazil between 1856 and 1860. (shrink)

Familiarity with Charles Darwin's treatise on evolution is essential to every well-educated individual. One of the most important books ever published--and a continuing source of controversy, a century and a half later--this classic of science is reproduced in a facsimile of the critically acclaimed first edition.

The present edition provides a detailed and accessible discussion ofhis theories and adds an account of the immediate responses to the book on publication.

Stephen Davies presents a fascinating exploration of the idea that art, and our aesthetic sensibilities more generally, should be understood as an element in human evolution. He asks: Do animals have aesthetics? Do our aesthetic preferences have prehistoric roots? Is art universal? What is the biological role of aesthetic and artistic behaviour?

The preservation of our planet’s decreasing biodiversity is a global challenge. Human attitudes and preferences toward animals have profound impacts on conservation policies and decisions. To date, the vast majority of studies about human attitudes and concern toward animals have focused largely on western, educated, industrialized, rich and democratic populations. In order to mitigate biodiversity loss globally, an understanding of how humans make decisions about animals from multicultural perspectives is needed. The present study examines familiarity, liking and endorsement of government (...) protection amongst six broad cultural groups living in Qatar for five threatened animal species indigenous to the Arabian Gulf. Our findings highlight similarities and differences across cultures toward animals. Overall, familiarity did not predict endorsement for government protection after liking was accounted for. Liking, however, emerged as an important predictor of endorsement for government protection across cultures, although the degree of animal liking varied culturally. WEIRD and South East Asian participants showed similar and more positive attitudes toward animals compared to the other groups. Participants from the Arabian Gulf, Sub-Saharan Africa, Middle East and North Africa, and South Asia responded similarly toward the animals. Interestingly, the Arabian Gulf group demonstrated significantly less liking and protection endorsement for animals, including those animals which play an important role in their culture. This research highlights intriguing avenues for future research and points to liking as a possible universal human attitude toward animals that influences decision making about conservation across all cultures while suggesting applications for improving education.

Four classes of naturally rare vascular plant species are described and classified, based on parameters of spatial distribution and longevity. Properties intrinsic to these time/space parameters are explored and an importance hierarchy of causes of rarity is proposed for each class. These hierarchies serve as the basis for a predictive classification. Human causes of rarity such as habitat destruction and taxonomic difficulties are not considered in detail here but are discussed as confounding factors in the elucidation of rarity in (...) vascular plants. Several examples are provided to illustrate this classification and provide testable hypotheses concerning the origins of natural rarity in plant species. (shrink)

This paper argues that a minimal notion of function and a notion of normal-proper function are used in explaining how bodies and brains operate. Neither is Cummins’ notion, as originally defined, and yet his is often taken to be the clearly relevant notion for such an explanatory context. This paper also explains how adverting to normal-proper functions, even if these are selected functions, can play a significant scientific role in the operational explanations of complex systems that physiologists and neurophysiologists provide, (...) despite a lack of relevant causal efficacy on the part of such functions.

The concept of species is one of the core concepts in biology and one of the cornerstones of evolutionary biology, yet it is rife with conceptual problems. Philosophers of biology have been discussing the concept of species for decades, and in doing so they sometimes appeal to the views of biologists. However, their statements as to what biologists think are seldom supported by empirical data. In order to investigate what biologists actually think about the key issues related to (...) the problem of species, we have conducted a survey on the sample of 193 biologists from the population of biologists from over 150 biology departments at universities in the US and the EU. This article presents and discusses the results of the survey. Some results confirm and others falsify the reiterated statements of philosophers of biology as to what biologists think, but all results we obtained should be informative and relevant for future discussions of the problem of species.

There is long-standing disagreement among systematists about how to divide biodiversity into species. Over twenty different species concepts are used to group organisms, according to criteria as diverse as morphological or molecular similarity, interbreeding and genealogical relationships. This, combined with the implications of evolutionary biology, raises the worry that either there is no single kind of species, or that species are not real. This book surveys the history of thinking about species from Aristotle to modern (...) systematics in order to understand the origin of the problem, and advocates a solution based on the idea of the division of conceptual labor, whereby species concepts function in different ways - theoretically and operationally. It also considers related topics such as individuality and the metaphysics of evolution, and how scientific terms get their meaning. This important addition to the current debate will be essential for philosophers and historians of science, and for biologists. (shrink)

Édouard Le Roy as early as 1901 observed the existence of an intellectual movement seeking to break from traditional positivism and set for himself the task of drawing up the program of this new positivism. Noting that this program precedes the Vienna Circle, I endeavor to determine its nature and to evaluate its impact on logical positivism. Viewed in this light, the discussions between Le Roy, Poincaré and Duhem appear more prolonged and substantial than is usually thought. What we have (...) here is perhaps not a homogeneous doctrine but a vigorous intellectual movement, from which logical positivists were able to borrow specific theses in their attempts to mitigate Mach's strict positivism; more important still, they had before them an example of neopositivism. History is not the only concern: among the issues debated, one encounters the claim that facts are theory-laden. This claim still stirs controversy today. An inquiry into the origins of the claim is one way of clarifying the arguments involved. (shrink)

This study sought to understand the effects of tone language repertoire and musical experience on nonnative lexical tone perception and production. Thirty-one participants completed a tone discrimination task, an imitation task, and a musical abilities task. Results showed that a larger tone language repertoire and musical experience both enhanced tone discrimination performance. However, the effects were not additive, as musical experience was associated with tone discrimination performance for single-tone language speakers, but such association was not seen for dual-tone language (...) speakers. Furthermore, among single-tone language speakers, but not among dual-tone language speakers, musical experience and musical aptitude positively correlated with tone discrimination accuracy. It is thus concluded that individuals with varying extents of tone language experience may adopt different strategies when performing tone discrimination tasks; single-tone language speakers may draw on their musical expertise while dual-tone language speakers may rely on their extensive tone language experience instead.

What are species? Are they objective features of the world? If so, what sort of features are they? Do everyday intuitions that species are real stand up to philosophical and scientific scrutiny? Two rival accounts of species' reality have dominated the discussion: that species are natural kinds defined by essential properties and that species are individuals. Unfortunately, neither account fully accommodates biological practice. In Are Species Real?, Slater presents a novel approach to this question (...) aimed at accommodating the attractions to both realism and antirealism about species. (shrink)

Abstract The thesis that teleological explanations are best understood as causal explanations is defended (contra Valentine). I shift the focus of debate from behavior simpliciter to allegedly rational behavior. Teleological explanation, in the case of rational agents, involves reason?giving; and the reasons agents give for acting must be causative of that action if those agents are to be rational in practice. I argue initially that to abandon the claim that reasons are causes of action is to abandon that which renders (...) many generalisations of systematic human behavior intelligible. I then adduce and defend against two major objections to the secondary thesis that reasons can be causes of action: (1) Experiments in attribution research suggest that agents are characteristically mistaken when reporting on the causes of their behavior; (2) Causal explanation must refer to some law, and reasons cannot enter into such laws as causes of action. In responding to these objections, I note that strict predictability is probably not a reliable indicator of genuine causal explanation; some explanations will afford predictions, others will not.
