The alien invasive Red King Crab in the Barents Sea represents both a threat, via ecosystem impacts, and a gain as a revenue source from food sales. Uncertainties exist regarding the ecological impacts but debate in Norway has also emphasised the economic benefits to marginalised fisher communities. This paper reports on a Q-methodology study involving key stakeholders to probe the extent to which divisions exist between different groups. While divisions are indeed found and two groupings identified, these are (...) not as clear as suggested by the lines typically portrayed in the media and elsewhere -, i.e. economic gains versus ecological preservation. Stakeholder groups reported here generally agreed that biodiversity concerns should be central and that further invasion was undesirable due to potential impacts on ecosystem services. (shrink)

This paper argues that the occurrence of a non-native species, such as purple loosestrife, on one's property does not constitute a nuisance in the context of background principles of common law. No one is injured by it. The control of non-native species, such as purple loosestrife, does not constitute a compelling public interest, moreover, but represents primarily the concern of an epistemic community of conservation biologists and ecologists. This paper describes a history of cases in agricultural law that (...) establish that a public authority may enter private property to destroy a tree or other species but only to protect a compelling public interest, such as the apple industry in Virginia or the citrus industry in Florida, and only if it pays all the costs including just compensation. The paper argues a fortiori that if a public authority enters private property to control non-native or “invasive” species it must pay all the costs and indemnify the owner—contrary to what many state laws contemplate and the Environmental Law Institute recommends.

The ecological impact of alien species is a function of the area colonised. Impact assessments of alien species are thus incomplete unless they take the spatial component of invasion processes into account. This paper describes a measure, termed expansion speed, that quantifies the speed with which a species increases its spatial presence in an assessment area. It is based on the area of occupancy and can be estimated from grid occupancies. Expansion speed is defined as (...) the yearly increase in the radius of a coherent circle having the same area as the AOO, irrespective of whether the increase is due to natural dispersal or anthropogenic transport. Two methods for estimating expansion speed are presented: one that requires several years of spatio-temporal observation data and explicitly takes detection rates into account; and one that can be used under a situation with sparse data. Using simulations and real-world data from natural history collections, it is shown that the method provides a good fit to observational datasets. Expansion speed has several valuable properties. Being based on AOO, it is an intuitive measure; as it only requires occupancy data, it is comparatively easy to estimate; and because it is a quantitative and generic measure, it increases the testability and comparability of impact assessments of alien species.

Our language and metaphors about environmental issues reflect and affect how we perceive and manage them. Discourse on invasive species is dominated by aggressive language of aliens and invasion, which contributes to the use of war-like metaphors to promote combative control. This language has been criticised for undermining scientific objectivity, misleading discourse, and restricting how invasive species are perceived and managed. Calls have been made for alternative metaphors that open up new management possibilities and reconnect with (...) a deeper conservation ethic. Here, we turn to Indigenous perspectives because they are increasingly recognised as offering important and novel voices in invasive species discourse. We examine how Australian Aboriginal elders and land managers (rangers) speak about 'environmental weeds' (the term used to describe invasive plants in Australia) and weed management. Based on qualitative research with five Aboriginal groups in the Kimberley region of Western Australia, our findings indicate that Aboriginal elders speak about weeds through passive, neutral language and prefer metaphors for weed management that focus on health, care and creation. We outline the influence that this language has for how rangers practice weed work and discuss its implications for the mainstream paradigm. (shrink)

Neobiota as non-native species are commonly considered as alien species. The Convention on Biological Diversity (CBD) intends to “prevent the introduction of, control or eradicate those alien species which threaten ecosystems, habitats or species”. The European Union has financed the DAISIE research project for the first pan-European inventory of Invasive Alien Species (IAS), which is supposed to serve as a basis for prevention and control of biological invasions. This paper discusses the (...) evaluation approach for classifying “100 of the Worst” IAS in Europe by the EU DAISIE research project. The main impact categories used by DAISIE for assorting “100 of the Worst” IAS are investigated and the texts of the “Wanted” species factsheets are examined. Two examples from the DAISIE factsheets of the “100 of the Worst” IAS [Tree of Heaven ( Ailanthus altissima ) and the Raccoon ( Procyon lotor )] are discussed to illustrate DAISIE’s biodiversity evaluation approach in more detail. However, the classification criteria used by DAISIE do not allow for sufficiently differentiating these neobiota from an ecological behavior of native species with a similar ecological niche. In conclusion, neobiota evaluations are not comprehensive when they refer mainly to the successful expansion and competition with native species into available ecological niches. A comprehensive assessment of the impacts of neobiota on biodiversity and humans needs to take into account the different values of biodiversity as mentioned in the preamble of the CBD. (shrink)

The study of biological invasions raises troubling scientific, political and moral issues that merit discussion and debate on a broad scale. Nativist trends in Conservation Biology have made environmentalists biased against alien species. This bias is scientifically questionable, and may have roots in xenophobic and racist attitudes. Rethinking conservationists' conceptions of biological invasion is essential to the development of a progressive environmental science, politics, and philosophy.

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.

Abstract:The focus of this paper is on managed relocations and endangered wild species. The main argument is that managed relocations should be a viable policy option in the toolbox of conservation management despite any ecological risks. This argument is defended on the basis of recent research that demonstrates that not all alien species are invasive species, and that not all invasive species have negative ecological impacts. In other words, a nuanced case-by-case approach is (...) needed. This argument is presented within the context of the Bramble Cay Melomys, a rat-like creature and the first mammal to become extinct as a result of anthropogenic climate change. A secondary objective of this paper is to explore some of the future economic and policy challenges likely to face managed relocations. (shrink)

The authors present a materialist analysis of the effects of neoliberalism in education. Specifically, they contend that neoliberalism is a form of cultural invasion that begets necrophilia. Neoliberalism is necrophilous in promoting a cultural desire to fix fluid systems and processes. Such desire manufactures both individuals known and culturally felt experiences of alienation which are, it is argued, symptomatic of an imperialist nostalgia that permeates educational policy and practice. The authors point to ‘unschooling in schools’ as a mechanism for resisting (...) the necrophilous tendencies of contemporary formations of education. (shrink)

The trade in, and private keeping of, reptiles as "pets" raises several ethical concerns regarding animal welfare (associated with handling, storage, transportation, intensive captive breeding, captivity stress, injury, disease, and high premature mortality); public health and safety (associated with zoonotic disease and animal-linked injuries); species conservation and environmental degradation (associated with wild capture); and ecological alteration (associated with invasive alien species). Also, many captive reptiles are fed other animals, raising broader ethical questions. Misperceptions about reptiles by (...) proponents of their captivity mean that these animals are subject to conditions that would likely be considered unacceptable for dogs or cats. (shrink)

Alien species are considered by conservation biologists to be a major threat to biodiversity. To deal with alien invasions, they often recommend completely eradicating the invasive species. Animal rights groups have continually opposed eradication campaigns, sometimes successfully. One such case was the attempted eradication of the grey squirrel from northern Italy.

Some critics of invasion biology have argued the invasion of ecosystems by nonindigenous species can create more valuable ecosystems. They consider invaded communities as more valuable because they potentially produce more ecosystem services. To establish that the introduction of nonindigenous species creates more valuable ecosystems, they defend that value is provisioned by ecosystem services. These services are derived from ecosystem productivity, the production and cycling of resources. Ecosystem productivity is a result of biodiversity, which is understood as local (...) species richness. Invasive species increase local species richness and, therefore, increase the conservation value of local ecosystems. These views are disseminating to the public via a series of popular science books. Conservationists must respond to these views, and I outline a method of rejecting such arguments against controlling invasive species. Ecological systems are valuable for more than local productivity and biodiversity is not accurately described by a local species count. (shrink)

If ecological systems are functionally organised, they can possess functions or malfunctions. Natural function would provide justification for conservationists to act for the protection of current ecological arrangements and control the presence of populations that create ecosystem malfunctions. Invasive species are often thought to be malfunctional for ecosystems, so functional arrangement would provide an objective reason for their control. Unfortunately for this prospect, I argue no theory of function, which can support such normative conclusions, can be applied to (...) large scale ecosystems. Instead ecological systems have causal structure, with small clusters of populations achieving functional arrangement. This, however, does not leave us without reason to control invasive species. We can look at the causal arrangement of ecological systems for populations that support ecological features that we should preserve. Populations that play a causal role in reducing biodiversity should be controlled, because biodiversity is a good all prudent agents should want to preserve. (shrink)

It is common for conservationists to refer to non-native species that have undesirable impacts on humans as “invasive”. We argue that the classification of any species as “invasive” constitutes wrongful discrimination. Moreover, we argue that its being wrong to categorize a species as invasive is perfectly compatible with it being morally permissible to kill animals—assuming that conservationists “kill equally”. It simply is not compatible with the double standard that conservationists tend to employ in their (...) decisions about who lives and who dies. (shrink)

This paper explores the ethical dimensions of lionfish removal and provides an argument supporting hunting lionfish for consumption. Lionfish are an invasive species found around the world. Their presence has fueled management strategies that predominantly rely on promoting human predation and consumption. We apply rights-based ethics, utilitarian ethics, and ecocentric environmental ethics to the question of whether hunting and eating lionfish is ethical. After applying these perspectives, we argue that, from a utilitarian perspective, lionfish should be culled. Rights-based (...) ethics, on the other hand, are not applicable in this case, while ecocentric environmental ethics would support lionfish removal. (shrink)

The importance of _naturalization_—the establishment of species introduced into foreign places—to the early development of Darwin’s theory of evolution deserves historical attention. Introduced and invasive European species presented Darwin with interpretive challenges during his service as naturalist on the HMS _Beagle_. Species naturalization and invasive species strained the geologist Charles Lyell’s creationist view of the organic world, a view which Darwin adopted during the voyage of the _Beagle_ but came to question afterward. I suggest (...) that these phenomena primed Darwin to question the “stability of species.” I then examine the role of introduced and invasive species in Darwin’s early theorizing and negotiation with Lyell’s ideas, recorded in his post-voyage “transmutation notebooks.” Therein, the subject was an inflection point in his contention with Lyell’s views and moreover, his theorizing on invasive species occasioned some of his earliest inklings of natural selection. Finally, I examine how naturalization was crucial to Lyell’s own eventual conversion to evolutionism. I conclude with brief reflections on the implications of this narrative for our understanding of Darwin’s reasoning, his intellectual relationship to Lyell, and the historical context that shaped his theory.

As I travel the highways of Georgia, I am regularly appalled by the ubiquitous presence of kudzu. It covers trees, telephone poles, open swathes of land, and old houses, making many locations indistinguishable from one another; all I can see from the road is a wave of green covering any formerly distinctive markings. Thinking back to the intentional introduction of kudzu to the American southeast, I recognize that those individuals who encouraged the planting of kudzu made a serious mistake.1 Their (...) introduction of an invasive species has produced real harms to my local ecosystem.In this paper I will argue that the introduction of invasive species should be avoided, not only because it may directly interfere with ..

Metaphors for describing the introduction, impacts, and management of non-native species are numerous and often quite outspoken. Policy-makers have adopted increasingly disputed metaphorical terms from scientific discourse. We performed a critical analysis of the use of strong metaphors in reporting scientific findings to policy-makers. Our analysis shows that perceptions of harm, invasiveness or nativeness are dynamic and inevitably display multiple narratives in science, policy or management. Improving our awareness of multiple expert and stakeholder narratives that exist in the context (...) of non-native species management, as well as metaphorical alternatives, is critical. (shrink)

Most current techniques to deal with invasive species are ineffective or have highly damaging side effects. To this end suppression-drives based on clustered regularly inter-spaced short palindromic repeats (CRISPR/Cas9) have been touted as a potential silver bullet for the problem, allowing for a highly focused, humane and cost-effective means of removing a target species from an environment. Suppression-drives come with serious risks, however, such that the precautionary principle seems to warrant us not deploying this technology. The focus (...) of this paper is on one such risk – the danger of a suppression-drive escaping containment and wiping out the target species globally. Here, I argue that in most cases this risk is significant enough to warrant not using a gene-drive. In some cases, however, we can bypass the precautionary principle by using an approach that hinges on what I term the ‘Worst-Case Clause’. This clause, in turn, provides us with a litmus test that can be fruitfully used to determine what species are viable targets for suppression-drives in the wild. Using this metric in concert with other considerations, I suggest that only three species are currently possible viable targets – the European rabbit, ship rat and Caribbean Tree Frog. (shrink)

The article attempts to bridge semiotics with species conservation and management. Biosemiotic and cultural semiotic methodology is applied in the analysis of a case study – the early occurrence of the golden jackal in Estonia. Nine semi-structured interviews were carried out with the local inhabitants of the Matsalu region, professional zoologists and environmental officials who were involved in the golden jackals’ discourse. The interviews were analyzed for interactions between golden jackals and humans, expected ecological effects of golden jackals, communication (...) between different interest groups and central cultural motifs used to interpret the new species. It is argued that in the development of this discourse, the golden jackals’ own activity has played an essential role. At the same time, human cultural models also influence the interpretation of a new species to a considerable degree. Two of such models – the opposition of the own and the alien and the “settler’s” narrative – are brought out and analyzed. The effect of the fear of the unknown is also specified. To improve human communication about new or invasive species, it is suggested to raise awareness of the underlying cultural models and to use integrative communication as the developing discourse is dynamical and constantly changing for all interest groups. For a semiotic study of species management, it is suggested to combine methodology from biosemiotics, cultural semiotics and actor-network theory. (shrink)

Biodiversity is the key indicator of a healthy planet and healthy society. Losses of biodiversity have now become widespread and current rates are potentially catastrophic for species and habitat integrity.

The authors argue that these aims can be achieved by a mix of (...) strict protection, inclusive involvement of people inside and adjacent to reserves, and by combining livelihoods and social well-being in all future biodiversity management. Case studies from regions around the world, including Europe, the United States, Latin America and Africa are examined and discussed, and the contributors include political scientists, economists and ecologists.

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.

The control of various introduced species brings to the fore questions around how species are categorised as ‘native’ or ‘invasive’, belonging or not belonging. In far north Queensland, Australia, the Cape York region is a complex mixture of land tenures, including pastoral leases, National Parks and Aboriginal land, and overlapping management agreements. Weed control comprises much of the work that land managers in Cape York do. However, different land managers target different introduced species for control, and (...) the ways in which certain species are understood as more or less problematic indicate how land managers understand and seek to order landscapes. Through investigating the various positions that introduced species occupy, I will explore how Cape York emerges as a ‘hybrid landscape’ that is produced in contested, overlapping and ambiguous ways, and is rife with ‘feral dynamics’.

In this article I respond to Wendell Kisner’s Hegelian environmental ethic. Kisner argues that because life is ontologically irreducible to mechanism it is rational to treat life not merely as a means to human purposes but as an end in itself. I argue that had Hegel consistently adhered to this position, he would have had to argue that the modern social world objectively alienates human beings from their rational selves. But Hegel in fact sees this social world as a home (...) for rational humanity. This is because Hegel believes life is ontologically higher than mechanism but ontologically lower than human mind. For Hegel therefore, minded beings may use life for their own self-objectification and self-realisation. (shrink)

For much of human history knowledge was communicated orally. Moral understandings were shared, developed and contextualized from generation to generation. Current moral theorists have argued that storied accounts may better serve to motivate ethical action and engage emotionally than standalone arguments.

Below is (...) a written version. (shrink)

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.

Purpose – This paper aims to explore similarities and differences between robots, invasive biological species, and genetically modified organisms. These comparisons are designed to better understand the potential effects of robots on human society. Design/methodology/approach – This paper applies established ideas in one discipline – biology – to issues that are less well understood, but actively being studied in another discipline – science and technology studies. Findings – Robots entering human society in large numbers share many of the (...) characteristics of an invasive species entering a new ecosystem. The authors also find that robots have several characteristics that are similar to a genetically modified organism. Taken together, these similarities suggest that society should be cautious about the introduction of large numbers of robots in a short period of time. Originality/value – The approach taken here to assess robots in society by these analogies to ecological processes is, to the authors' knowledge, novel. Applying ideas from a better-known area to a less well-known area is routine in philosophy, but these particular analogies have not yet been carefully articulated in the literature. (shrink)

This article calls for an end to the use of the term ‘invasive species’, both in the scientific and public discourse on wildlife conservation. There are two broad reasons for this: the first problem with the invasive species narrative is that this demonisation of ‘invasives’ is morally wrong, particularly because it usually results in the unjust killing of the animals in question. Following on from this, the second problem is that the narrative is also incoherent, both (...) from scientific and philosophical perspectives. At the heart of both of these issues is the problem that the invasive species narrative oversimplifies what are in fact very complex biological processes. As a result, the policies carried out with the stated aim of ‘controlling’ these animals are often unethical. In light of the current global species decline, this article asserts that the way we think and talk about these animals should be changed and the term ‘invasive species’ should be discontinued, in the hope that this leads to changes in practice.

Long before the viewers of Ridley Scott's Alien catch their first, fleeting glimpse of the terrifying alien, they have already made the acquaintance of the alienated human beings aboard the USCSS Nostromo.

In fact, the human members of the crew of the Nostromo exhibit “alienation”, a condition identified by Karl Marx in the “Estranged Labor” section of his Economic and (...)

A hard difficulty in Astrobiology is the precise definition of what life is. All living beings have a cellular structure, so it is not possible to have a broader concept of life hence the search for extraterrestrial life is restricted to extraterrestrial cells. Earth is an astronomical rarity because it is difficult for a planet to present liquid water on the surface. Two antagonistic bioethical principles arise: planetary protection and terraforming. Planetary protection is based on the fear of interplanetary cross-infection (...) and possible ecological damages caused by alien living beings. Terraforming is the intention of modifying the environmental conditions of the neighbouring planets in such a way that human colonisation would be possible. The synthesis of this antagonism is ecopoiesis, a concept related to the creation of new ecosystems in other planets. Since all the multicellular biodiversity requires oxygen to survive, only extremophile microorganisms could survive in other planets. So, it could be carried out a simulation of a meteorite by taking to other planets portions of the terrestrial permafrost, or ocean or soil, so that if a single species could grow, a new ecosystem would start, as well as a new Natural History. As a conclusion, ecopoiesis should be the bioethical principle to guide practices and research in Astrobiology. (shrink)

Many aquatic invasive species (AIS) management programs are doing important work on preventing non-indigenous species movement to our wild places. Attitudes and perspectives on aquatic non-indigenous species and their management by ecologists and the public are fundamentally a question of human values. Despite eloquent philosophical writings on treatment of non-indigenous species, management agency rhetoric on 'invasive' species usually degenerates to a good versus evil language, often with questionable results and lost conservation dollars. We (...) assess and learn from an established AIS program. We discuss an ethic framework and operational directives to minimise the trap of a binary classification of species into bad or good, and we advocate for a principled pragmatic approach to minimise conflicts. We make a case for not labelling species and instead focusing on managing nuisance conditions and protecting ecosystem health. (shrink)

Evans et al. (Journal of Agricultural and Environmental Ethics, 2008) have attempted to enmesh me in their dispute with the Florida Bureau of Invasive Plant Management about a specific system, Kings Bay/Crystal River. In so doing, they repeatedly mischaracterize my positions in order to depict, incorrectly, invasion biology as monolithic and me as a representative of one extreme of a false dichotomy about management of introduced species. In addition, they introduce an issue irrelevant in this case (extinctions) and (...) cite incorrect data. Proposing to manage people, manatees, introduced plants, and cyanobacteria in Kings Bay by participative adaptive management, they ignore the fact that living organisms can both disperse autonomously and hitchhike. Finally, they present few details on any aspect of their management proposal and do not address the myriad problems that have beset previous attempts at scientific adaptive management, especially at large scales. Until such a management approach is fleshed out and implemented, it is impossible to assess its validity for Kings Bay, and it is very premature to suggest it as a general model for dealing with invasive species disputes.

Proponents of ecological restoration view the practice as a means of both repairing damage done to ecosystems by humans and creating an avenue to re-establish respectful and cooperative human-environment relationships. One debate affecting ecological restoration focuses on the place of 'exotic' species in restored ecosystems. Though popular, campaigns against exotics have been criticized for their troubling rhetorical parallels with nativism aimed at human immigrants. I point to some of the reasons why this critique of nativism persists, despite protests that (...) no xenophobic intent is evident, emphasizing the intimacy between social metaphors and claims about exotic nature. Language is but one facet of an entanglement of nature and society that ecological restoration strives to take seriously; however, restoration practice remains ambivalent toward this dichotomy permitting a longing for lost community purity that is embraced in nativism. Regarding defenses of nativism, I point out limitations of attempts to reframe the issue from a reactionary rejection of the foreign Other toward an argument for protecting communities from a process akin to 'cultural imperialism'.

Leading invasion biologists sometimes dismiss critics and criticisms of their field by invoking “the straw man” fallacy. Critics of invasion biology are also labelled as a small group of “naysayers” or “contrarians”, who are sometimes engaging in “science denialism”. Such unfortunate labels can be seen as a way to possibly suppress legitimate debates and dismiss or minimize reasonable concerns about some aspects of invasion biology, including the uncertainties about the geographic origins and complex environmental impacts of species, and the (...) control programs against species perceived as “invasive”. In assessing the quality of the debate in this area, we examine the validity of the use of various strategies, including the “straw man” concept, and explore a range of potential logical fallacies present in some recent prominent discussions about invasion biology and so-called “invasive” species. The goal is to add some clarity to the concepts involved, point out some problematic issues, and improve the quality of the debates as the discussions move forward. (shrink)

Species spreading beyond their native ranges are important study objects in ecology and environmental sciences and research on biological invasions is thriving. Along with an increase in the number of publications, the research field is experiencing an increase in the diversity of methods applied and questions asked. This development has facilitated an upsurge in information on invasions, but it also creates conceptual and practical challenges. To provide more transparency on which kind of research is actually done in the field, (...) the distinction between invasion science, encompassing the full spectrum of studies on biological invasions and the sub-field of invasion biology, studying patterns and mechanisms of species invasions with a focus on biological research questions, can be useful. Although covering a smaller range of topics, invasion biology today still is the driving force in invasion science and we discuss challenges stemming from its embeddedness in the social context. Invasion biology consists of the building blocks 'theory', 'case studies' and 'application', where theory takes the form of conceptual frameworks, major hypotheses and statistical generalisations. Referencing recent work in philosophy of science, we argue that invasion biology, like other biological or ecological disciplines, does not rely on the development of an all-encompassing theory in order to be efficient. We suggest, however, that theory development is nonetheless necessary and propose improvements. Recent advances in data visualisation, machine learning and semantic modelling are providing opportunities for enhancing knowledge management and presentation and we suggest that invasion science should use these to transform its ways of publishing, archiving and visualising research. Along with a stronger focus on studies going beyond purely biological questions, this would facilitate the efficient prevention and management of biological invasions. (shrink)

Marx's theory of alienation is of great importance to contemporary political developments, due both to the re-emergence of anti-capitalist struggle in Zapatismo, 21st Century Socialism, and the New Democracy Movement, and to the fact that the most important theorists of these movements single out Marx's theory of alienation as critical to their concerns. Despite this renewed practical and theoretical interest, however, these and other writers have been sparing in their accounts of the normative components which the theory of alienation incorporates.

Along with many recent commentators, I argue that the normative components of the theory of alienation are to be found in a notion of human development, and that a conception of the particular importance of the human species-essence plays a critical role in this respect.

In his essay “The Human Prejudice” Bernard Williams presented a sophisticated defense of the moral relevance of the concept “human being”. Here I offer both an analysis of his essay and a defense of his conclusions against criticisms made by Julian Savulescu and Peter Singer.

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.
