It is now widely accepted that microorganisms play many important roles in the lives of plants and animals. Every macroorganism has been shaped in some way by microorganisms. The recognition of the ubiquity and importance of microorganisms has led some to argue for a revolution in how we understand biological individuality and the primary units of natural selection. The term “holobiont” was introduced as a name for the biological unit made up by a host and all of its associated microorganisms, (...) and much of this new debate about biological individuality has focused on whether holobionts are integrated individuals or communities. In this paper, I show how parts of the holobiont can span both characterizations. I argue that most holobionts share more affinities with communities than they do with organisms, and that, except for maybe in rare cases, holobionts do not meet the criteria for being organisms, evolutionary individuals, or units of selection.

The species problem is the longstanding puzzle regarding the nature of species. This paper aims to describe how biologists experience little communication breakdown when they have different conceptions of species. For this purpose, I analyze two debates on species and speciation between Guy Bush and Jerry Coyne & H. Allen Orr. Although they have radically different ideas on species, they experience little communication difficulty. I will argue that this is because they implicitly agreed (...) on the referent of the group of organisms being addressed and possible causal factors of the speciation process. This analysis confirms a leading account in the general philosophy of science on the way in which scientists avoid the incommensurability threat. (shrink)

The way people come to report private stimulation arising within their own bodies is not well understood. Although the Darwinian assumption of biological continuity has been the basis of extensive animal modeling for many human biological and behavioral phenomena, few have attempted to model human communication based on private stimulation. This target article discusses such an animal model using concepts and methods derived from the study of discriminative stimulus effects of drugs and recent research on interanimal communication. We (...) discuss how humans acquire the capacity to identify and report private stimulation and we analyze intra- and interspecies differences in neurochemical mechanisms for transducing interoceptive stimuli, enzymatic and other metabolic factors, learning ability, and discrimination learning histories and their relation to psychiatric and developmental disabilities.

Species are ordinarily conceived of as being native or non-native to either a geographical location or an ecological community. I submit that species may also be native or non-native to human communities. I argue, by way of an analogy with varieties of domesticated and cultivated species, that this sense of nativity is grounded by the cultural relationships human communities have with species. A further analogy is drawn with the motivations of varietal nativists – who seek to (...) protect native varieties of domesticated and cultivated species for the sake of their cultural value – to argue for the consideration of the cultural value of native species in environmental policy decisions regarding invasive non-native species.

We defend a realistic attitude towards biological species. We argue that two species are not different species because they differ in intrinsic features, be they phenotypic or genomic, but because they are separated with regard to gene flow. There are no intrinsic species essences. However, there are relational ones. We argue that bearing a gene flow relation to conspecifics may serve as the essence of a species. Our view of the species as a Gene-Flow (...) Community differs from Mayr’s definition of the species as a reproductive community. In a reproductive community, each organism is able to successfully reproduce with each other. However, there are species in which geographically distant organisms lost their ability to successfully reproduce, due to strong genetic adaptations to the respective local environmental conditions. Despite this loss of the ability to mutually reproduce, they are still bound by gene flow via continuous intermediate populations. This replacement of Mayr’s notion of an interbreeding potential as a criterion for species membership has important implications for the treatment of populations in allopatry and sympatry. (shrink)

This paper analyzes community ecologist Charles Elton’s ideas on animal communities, and situates them with respect to the classical opposition between organicist–holistic and individualistic–reductionist ecological views drawn by many historians of ecology. It is argued that Elton espoused a moderate ecological holism, which drew a middle way between the stricter ecological holism advocated by organicist ecologists and the merely aggregationist views advocated by some of their opponents. It is also argued that Elton’s moderate ecological holism resonated with his preference for (...) analogies between ecological communities and human societies over more common ones between communities and individual organisms. I discuss, on the one hand, how the functionalist-interactionist approach to community ecology introduced by Elton entailed a view of ecological communities as more or less self-maintaining functionally organized wholes, and how his ideas on this matter were incorporated into their views by organicist ecologists Frederic Clements, Victor Shelford, and Warder C. Allee et al. On the other hand, I identify some important divergences between Elton’s ecological ideas and those of organicist ecologists. Specifically, I show how Elton’s ideas on species distribution, animal migrations, and ecological succession entailed a view of animal communities as exhibiting a weaker degree of part-whole integration than that attributed to them by Clements and Shelford; and how Elton’s mixed stance on the balance of nature idea and his associated views on community stability attributed to communities a weaker form of self-regulation than that attributed to them by Allee et al.

In The Origin of Species (1859) Darwin challenged many of the most deeply-held beliefs of the Western world. Arguing for a material, not divine, origin of species, he showed that new species are achieved by "natural selection." The Origin communicates the enthusiasm of original thinking in an open, descriptive style, and Darwin's emphasis on the value of diversity speaks more strongly now than ever. As well as a stimulating introduction and detailed notes, this edition offers a register (...) of the many writers referred to by Darwin in the text. (shrink)

Can mere conceptual competence explain the apriori? Many contemporary theorists believe that conceptual competence grounds apriori conceptual truths – and that this fact helps explain how thinkers can have apriori justification for accepting these truths and reasoning in accord with them. In this chapter, I'll examine several contemporary defenses of the conceptual approach to apriority in order to clarify their core commitments about the nature of concepts. The common thread, I'll argue, is a picture of concepts that combines a conceptual (...) role model of conceptual competence with a rationalizing approach to the determination of semantic contents. My first aim is to show how this model of concepts has the potential to ground apriori truth and justification. My second aim is to show how the model involves problematic commitments about concepts, which can be avoided on an alternative relational model of concepts. (shrink)

All methodologies used to characterize mother-infant interaction in non-human primates includes mother, infant, and other social factors. The chief difference is their understanding of how this interaction takes place. Using chimpanzees as a model, I will compare the different methodologies used to describe mother-infant interaction and show how implicit notions of communication and social interaction shape descriptions of this kind of interaction. I will examine the limitations and advantages of different approaches used in mother-infant studies and I will sketch (...) an alternative approach to studying mother-infant interaction in non-human primates that adopts Jerome Bruner’s developmental studies on human infant communication.

Systematic sampling of communities gives rise to large contingency tables summing up possible changes in the assemblages' structure. Such tables are generally analysed by multivariate statistical methods, which are ill-suited for simultaneously analysing rare and common species (Field et al., 1982). In order to separately process species belonging to either of these categories, we propose a statistical method to select common species in a sequence of ecological surveys. It is based on a precise definition of rarity, and (...) depends on a rarity parameter. In this work, this parameter will be optimised so that the sub-table of common species captures the essential features of the complete table as well as possible. In this way we analysed the spatio-temporal evolution of macrobenthic communities from the Algiers harbour to study the pollution influence during a year. The examination of the communities' structuring was done through Principal Components Analysis (PCA) of the species proportions table. Environmental variables were simultaneously sampled. We show that the data structure can be explained by about 25% of the total number of present species. Two environmental gradients were brought to the fore inside the harbour, the first one representing pollution, and the second one representing hydrological instabilities. (shrink)

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)

As a contribution to the debate on the future of philosophy as an autonomous discipline beyond its current function within Western-type universities, a comparison is offered between three diverging strategies of “speaking the universal” which keep their relevance today; the “Double Truth” strategy for secular tolerance, illustrated by Spinoza and Wittgenstein; the construction of the universal as “hegemony,” analyzed by Hegel and Marx in terms of collective consciousnesses or ideologies; and the program of generalized translation as it emerges from the (...) critique of traditional “paradoxes of the untranslatable” in the works of contemporary socio-linguists and pragmatic philosophers. The conclusion remains an open questioning on the equivocity of the universal. (shrink)

Biopolitical analyses of census -taking usually focus on human censuses and consider how human experience is shaped by the practice. Instead, this article looks at the proposed global biodiversity census, which aims to take inventory of every species on earth as a response to anthropogenic species extinction. I suggest that it is possible to extend and modify Foucault's concept of biopower to consider contemporary human-nonhuman interactions. Specifically, I argue that an ecologically-extended version of biopower offers a useful way (...) to conceptualise how power circulates in the practices that surround the biodiversity census, and that it points us towards thinking about how analyses of power, authority, and community can consider ecological, rather than purely human, locations and networks.

Recent research on bacteria and other microorganisms has provided interesting insights into the nature of life, cooperation, evolution, individuality or species. In this paper, I focus on the capacity of bacteria to produce molecules that are usually classified as ’signals’ and I defend two claims. First, I argue that certain interactions between bacteria should actually qualify as genuine forms of communication. Second, I use this case study to revise our general theories of signaling. Among other things, I argue (...) that a plausible requirement for a state to qualify as a signal is that it is a minimal cause. (shrink)

It has become increasingly clear that social learning and culture occur much more broadly, and in a wider variety of animal communities, than initially believed. Recent research has expanded the list to include insects, fishes, elephants, and cetaceans. Such diversity allows scientists to expand the scope of potential research questions, which can help form a more complete understanding of animal culture than any single species can provide on its own. It is crucial to understand how culture and social learning (...) present in different communities, as well as what influences community structure and culture may have on one another, so that the results across these different studies may most effectively inform one another. This review presents an overview of social learning in species across a spectrum of community structures, providing the necessary infrastructure to allow a comparison of studies that will help move the field of animal culture forward.

It is sometimes argued that while human gestures are produced ostensively and intentionally, great ape gestures are produced only intentionally. If true, this would make the psychological mechanisms underlying the different species’ communication fundamentally different, and ascriptions of meaning to chimpanzee gestures would be inappropriate. While the existence of different underlying mechanisms cannot be ruled out, in fact claims about difference are driven less by empirical data than by contested assumptions about the nature of ostensive communication. On (...) some accounts, there are no reasons to doubt that great ape gestural communication is ostensive. If these accounts are correct, attributions of meaning to chimpanzee gestures would be justified. (shrink)

In this paper, I critically assess Mark Richard’s interesting and important development of the claim that linguistic meanings can be fruitfully analogized with biological species.

Butler's commentary on other animals remains dispersed and fragmented throughout books, lectures, and interviews over the course of the last several years. This work is critically synthesized in conjunction with her work on mourning and precarious lives. By developing an anti-anthropocentric understanding of mourning and precarious lives, this article hopes to create ontological, ethical, (...) and political concepts that resist the violence of the present. In so doing, the article contrasts Butler's understanding of precarious life with Giorgio Agamben's understanding of bare life in order to conceive of precariousness as constitutive of social reality. This intellectual labor lays the groundwork for understanding mourning the lives of other animals as a political act that produces new communities, rather than as an individuating and isolating emotion.

The organism is one of the fundamental concepts of biology and has been at the center of many discussions about biological individuality, yet what exactly it is can be confusing. The definition that we find generally useful is that an organism is a unit in which all the subunits have evolved to be highly cooperative, with very little conflict. We focus on how often organisms evolve from two or more formerly independent organisms. Two canonical transitions of this type—replicators clustered in (...) cells and endosymbiotic organelles within host cells—demonstrate the reality of this kind of evolutionary transition and suggest conditions that can favor it. These conditions include co-transmission of the partners across generations and rules that strongly regulate and limit conflict, such as a fair meiosis. Recently, much attention has been given to associations of animals with microbes involved in their nutrition. These range from tight endosymbiotic associations like those between aphids and Buchnera bacteria, to the complex communities in animal intestines. Here, starting with a reflection about identity through time, we consider the distinctions between these kinds of animal–bacteria interactions and describe the criteria by which a few can be considered jointly organismal but most cannot.

Communication, when defined as an act intended to affect the psychological state of another individual, demands the use of inference. Either the signaler, the recipient, or both must make leaps of understanding which surpass the semantic information available and draw from pragmatic clues to fully imbue and interpret meaning. While research into human communication and the evolution of language has long been comfortable with mentalistic interpretations of communicative exchanges, including rich attributions of mental state, research into animal (...) class='Hi'>communication has balked at theoretical models which describe mentalized cognitive mechanisms. We submit a new theoretical perspective on animal communication: the model of inferential communication. For use when existing proximate models of animal communication are not sufficient to fully explain the complex, flexible, and intentional communication documented in certain species, specifically non-human primates, we present our model as a bridge between shallower, less cognitive descriptions of communicative behavior and the perhaps otherwise inaccessible mentalistic interpretations of communication found in theoretical considerations of human language. Inferential communication is a framework that builds on existing evidence of referentiality, intentionality, and social inference in primates. It allows that they might be capable of applying social inferences to a communicative setting, which could explain some of the cognitive processes that enable the complexity and flexibility of primate communication systems. While historical models of animal communication focus on the means-ends process of behavior and apparent cognitive outcomes, inferential communication invites consideration of the mentalistic processes that must underlie those outcomes. We propose a mentalized approach to questions, investigations, and interpretations of non-human primate communication. We include an overview of both ultimate and proximate models of animal communication, which contextualize the role and utility of our inferential communication model, and provide a detailed breakdown of the possible levels of cognitive complexity which could be investigated using this framework. Finally, we present some possible applications of inferential communication in the field of non-human primate communication and highlight the role it could play in advancing progress toward an increasingly precise understanding of the cognitive capabilities of our closest living relatives.

Abstract The ‘species problem’ in the philosophy of biology concerns the nature of species. Various solutions have been proposed, including arguments that species are sets, classes, natural kinds, individuals, and homeostatic property clusters. These proposals parallel debates in ecology as to the ontology and metaphysics of populations, communities and ecosystems. A new solution—that species are processes—is proposed and defended, based on Robert Ulanowicz’s metaphysics of process ecology. As with ecological systems, species can be understood as (...) emergent, autocatalytic systems with propensities for centripetality and mutuality in the course of dynamically balancing ascendency (order and persistence) and overhead (randomness and change). The species-as-processes perspective accords with the Ulanowicz’s postulates of process ecology and it can be accommodated by existing theories of species—particularly in a reframing of Richard Boyd’s metaphysics such that species are homeostatic process clusters. Rather than contending that process-based metaphysics is the only, best or true account of species, a pluralist-realist approach is advocated based on the pragmatic principles that are reflected in modern view of species and ecology. If species are understood to be comprised of processes and to be emergent processes themselves, there are important implications for the life sciences, including: animal models in medical and environmental studies, conservation biology, extinction, biodiversity, restoration ecology, and evolutionary biology.

Individuals of some animal species have been taught simple versions of human language despite their natural communication systems failing to rise to the level of a simple language. How is it, then, that some animals can master a version of language, yet none of them deploy this capacity in their own communication system? I first examine the key design features that are often used to evaluate language-like properties of natural animal communication systems. I then consider one (...) candidate animal system, bird song, because it has several of the key design features or their precursors, including social learning and cultural transmission of their vocal signals. I conclude that although bird song communication is nuanced and complex, and has the acoustic potential for productivity, it is not productive – it cannot be used to say many different things. Finally, I discuss the debate over whether animal communication should be viewed as a cooperative information transmission process, as we typically view human language, or as a competitive process where signaler and receiver vie for control. The debate points to a necessary condition for the evolution of a simple language that has generally been overlooked: the degree of to which the interests of the signaler and receiver align. While strong cognitive and signal production mechanisms are necessary pre-adaptations for a simple language, they are not sufficient. Also necessary is the existence of identical or near-identical interests of signaler and receiver and a socio-ecology that requires high-level cooperation across a range of contexts. In the case of our hominid ancestors, these contexts included hunting, gathering, child care and, perhaps, warfare. I argue that the key condition for the evolution of human language was the extreme interdependency that existed among unrelated individuals in the hunter-gatherer societies of our hominid ancestors. This extreme interdependency produced multiple prosocial adaptations for effective intragroup cooperation, which in partnership with advanced cognitive abilities, set the stage for the evolution of language.

Seeking a scientific basis for understanding and treating mental illness, and inspired by the work of Ivan Pavlov, American physiologists, psychiatrists and psychologists in the 1920s turned to nonhuman animals. This paper examines how new constructs such as “experimental neurosis” emerged as tools to enable psychiatric comparison across species. From 1923 to 1962, the Cornell “Behavior Farm” was a leading interdisciplinary research center pioneering novel techniques to experimentally study nonhuman psychopathology. Led by the psychobiologist Howard Liddell, work at the (...) Behavior Farm formed part of an ambitious program to develop new preventative and therapeutic techniques and bring psychiatry into closer relations with physiology and medicine. At the heart of Liddell’s activities were a range of nonhuman animals, including pigs, sheep, goats and dogs, each serving as a proxy for human patients. We examine how Pavlov’s conceptualization of ‘experimental neurosis’ was used by Liddell to facilitate comparison across species and communication between researchers and clinicians. Our close reading of his experimental system demonstrates how unexpected animal behaviors and emotions were transformed into experimental virtues. However, to successfully translate such behaviors from the animal laboratory into the field of human psychopathology, Liddell increasingly reached beyond, and, in effect, redefined, the Pavlovian method to make it compatible and compliant with an ethological approach to the animal laboratory. We show how the resultant Behavior Farm served as a productive “hybrid” place, containing elements of experiment and observation, laboratory and field. It was through the building of close and more naturalistic relationships with animals over extended periods of time, both normal and pathological, and within and outside of the experimental space, that Liddell could understand, manage, and make useful the myriad behavioral complexities that emerged from the life histories of experimental animals, the researchers who worked with them, and their shared relationships to the wider physical and social environments.

Microalgae in the wild often form consortia with other species promoting their own health and resource foraging opportunities. The recent application of microalgae cultivation and deployment in commercial photobioreactors (PBR) so far has focussed on single species of algae, resulting in multi-species consortia being largely unexplored. Reviewing the current status of PBR ecological habitat, this article argues in favor of further investigation into algal communication with conspecifics and interspecifics, including other strains of microalgae and bacteria. These (...) mutualistic species form the ‘phycosphere’: the micro-environment surrounding microalgal cells, potentiating the production of certain metabolites through biochemical interaction with cohabitating microorganisms. A better understanding of the phycosphere could lead to novel PBR configurations, capable of incorporating algal-microbial consortia, potentially proving more effective than single-species algal systems.

Within the last 20 years, the US has mounted amassive campaign against invasions bynon-indigenous species (NIS) such as zebramussels, kudzu, water hyacinths, and brown treesnakes. NIS have disrupted native ecosystemsand caused hundreds of billions of dollars ofannual damage. Many in the scientificcommunity say the problem of NIS is primarilypolitical and economic: getting governments toregulate powerful vested interests thatintroduce species through such vehicles asships' ballast water. This paper argues that,although politics and economics play a role,the problem is primarily one (...) of scientificmethod. Even if commercial interests werewilling to spend the necessary funds to controlNIS, and even if government were willing toregulate them, ecological theory is notadequate to provide clear direction for eithereffort. The paper argues there is nocomprehensive, predictive theory ofinvasibility, as part of a larger theory ofcommunity structure, that might guideecological decision making regarding NIS, andfor at least three reasons. (1) There is nofirm definition of NIS, native, exotic,and so on, and ecologists do not use the termsconsistently; as a result, biologists debatingvarious accounts of community structure andecological explanation often do not even makelogical contact with each other. (2) Thedominant theory used to understandinvasibility, island biogeography, has noprecise predictive power and is unable toclarify when NIS might promote biodiversity andwhen they might hinder it. (3) There are nofirm, empirical generalizations that revealwhen a colonizer or a NIS might be likely totake over a new environment, and when it mightnot succeed in doing so. As a result,scientists have only rough rules of thumb toshore up their arguments against NIS. Given theincompleteness of current ecological theory,the paper closes with several suggestions forways that study of NIS might enhanceunderstanding of basic commmunity structuresand vice versa.

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.

Literary trauma theory has traditionally been a humanist concern, and the concept of witnessing, so central to the theorization of trauma, has focused on human experience and relationships. This article stages an interdisciplinary intervention by conceptualizing trans-“species” trauma testimony as a literary encounter involving a double-layered witnessing; the human artist witnessing nonhuman animals’ witnessing to the failings and crises brought about by human society. Focusing on a selection of contemporary Australian poems, a view emerges of poetic witnessing and testimony (...) that exceeds and complicates the sub-genre lenses of old such as “nature poetry,” “ecopoetry,” and “protest poetry.” I propose a new conceptual category that testifies to traumatic structures and consequences of human practices. I explore how this testimony proceeds through a two-way channel of witnessing in which nonhuman animals are active witnessing agents and not merely witnessed by humans. I concentrate on witnessing as primarily experiential, as a corporal, affective operation in which the senses figure centrally. I argue that when poets witness nonhuman animal experience in poetry, testimony advances as an ethical engagement in an act of solidarity and advocacy. Poetry offers productive potential in this respect due to its affinity for engagement with the senses, its capacity to communicate heightened affect, and its scope for expression, articulation, and evocations of meaning outside of conventional sense-making and the limits of rational understanding.

Although the intrinsic physicality of human beings has not changed in millennia, the species has managed to profoundly reconstitute the physical and social world it inhabits. Although the word “profound” is insufficient to describe the vast changes our world has undergone, it is sufficiently neutral to encompass both the opportunities—and the challenges—that our age provides. It is a premise of my work that technology, particularly information and communication technology (ICT), offers spectacular opportunities for humankind to address its collective (...) problems. The problems themselves are equally spectacular that is war and militarism, poverty, environmental depletion and destruction, disease, etc., and lack of successful alleviation may prove catastrophic. Humankind’s problems will not be solved by elite fiat, by chance, or as a side-effect of the “free market.” To address these challenges effectively and appropriately, “civic intelligence” will be required. This paper is designed to explore the relation between community networks and the nascent concept of civic intelligence. Civic intelligence describes the capacity of society to consciously adapt to its environment and shape a future environment that is healthy, equitable, and sustainable. Although individuals contribute to civic intelligence, the concept describes a phenomenon that is collective and distributed. This paper argues that community networks were an important manifestation of civic intelligence in the early days of the Internet revolution. It further argues that a theory of civic intelligence can be used to account for the declining influence of traditional community networks and to provide useful prescriptions for renewed vitality and influence of community networks in the future.

There are two facts about word learning that everyone accepts. The first is that words really do have to be learned. There is controversy over how much conceptual structure and linguistic knowledge is innate, but nobody thinks that this is the case for the specific mappings between sounds (or signs) and meanings. This is because these mappings vary arbitrarily from culture to culture. No matter how intelligent a British baby is, for instance, she still has to learn, by attending to (...) the language of the people around her, that rabbits are called ‘rabbits’, that sleeping is called ‘sleeping’, and so on.

New techniques for the genetic modification of organisms are creating new strategies for addressing persistent public health challenges. For example, the company Oxitec has conducted field trials internationally—and has attempted to conduct field trials in the United States—of a genetically modified mosquito that can be used to control dengue, Zika, and some other mosquito-borne diseases. In 2016, a report commissioned by the National Academies of Sciences, Engineering, and Medicine discussed the potential benefits and risks of another strategy, using gene drives. (...) Driving a desired genotype through a population of wild animals or insects could lead to irreversible genetic modification of an entire species. The NASEM report recommends community, stakeholder, and public engagement about potential uses of the technology, and it argues that the engagement should occur as research advances, well before gene drives are deployed. Yet what “engagement” means in practice is unclear. This article seeks clarity on this problem by offering a justification for community engagement and drawing out implications of this argument for the implementation and desired outcomes of community engagement. Community engagement is essential when it comes to research that would release genetically modified insects or animals into the environment. By contrast, obtaining informed consent from people who live near such a proposed field trial is neither necessary nor sufficient. Drawing on the epistemic and moral arguments for deliberative democracy, I propose two discrete mechanisms of community engagement: community advisory boards and deliberative forums, neither of which has been systematically incorporated into research governance. The proposed mechanisms would engender respect for persons who live near field trials, even when the results of deliberation override some individuals’ preferences. Community engagement foregrounds the community in our thinking about humans’ relationship to nature, and it implies that deciding to release genetically modified insects or animals into the wild ought to be a collective decision, not one made by product developers, policy-makers, private companies, research funders, or scientists alone.

The Endangered Species Act of 1973 (ESA) is America's strongest environmental law. Its citizen-suit provisionany personawards implicit intrinsic value, de facto standing, and operational legal rights (sensu Christopher D. Stone) to listed species. Accordingly, some cases had gone forward in the federal courts in the name of various listed species between 1979 (Palila v. Hawaii Dept. of Land & Natural Resources) and 2004 (Cetacean Community v. Bush), when the Ninth Circuit Court of Appeals ruled that animals could (...) not sue in their own name. Because the Supreme Court has interpreted its habitat destruction as the of a listed species, some have argued that enforcement of the ESA's critical-habitat-protection provision is a of private property without just compensation, contrary to the Fifth Amendment of the Constitution. The courts have not agreed. The ESA citizen-suit provision appears to waive federal-court standing requirements devolved from Article III of the U.S. Constitution, creating much confusion and mutually contradictory rulings. A series of cases (culminating with Bennett v. Spear) reconciles the ESA's citizen-suit provision with the particularized and concrete standing requirements devolved from Article III. (shrink)

It has recently been argued that our use of vague language poses an intractable problem for any account of content and communication on which (i) the things we assert are propositions and (ii) understanding an assertion requires recognizing which proposition the speaker asserted. John MacFarlane has argued that this problem concerning vague language is itself a species of an even more general problem for such traditional accounts – the problem posed by “felicitous” underspecification. Repurposing certain ideas from Allan (...) Gibbard, MacFarlane offers a novel theory of vagueness, plan-expressivism, as an account that can handle both vagueness and such underspecification in communication. -/- In this paper, I argue that despite its many virtues, plan-expressivism fails as a general account of meaning and communication. In particular, I show that when it comes to the problem of felicitous underspecification, plan-expressivism fares no better than the more traditional accounts of content and communication it is intended to replace. Along the way, I argue that the problem of felicitous underspecification puts considerable pressure on an assumption that is at the core of both plan-expressivism and the accounts of its more traditionalist rivals - namely, that in cases of successful linguistic communication, we must always be able to find something -- whether a propositional content or a conversational update -- that the speaker is intending to share with her audience.

Traditional diversity measures such as the Shannon entropy are generally computed from the species' relative abundance vector of a given community to the exclusion of species' absolute abundances. In this paper, I first mention some examples where the total information content associated with a given community may be more adequate than Shannon's average information content for a better understanding of ecosystem functioning. Next, I propose a parametric measure of statistical information that contains both Shannon's entropy and total information (...) content as special cases of this more general function. (shrink)

Holobionts are multicellular eukaryotes with multiple species of persistent symbionts. They are not individuals in the genetic sense— composed of and regulated by the same genome—but they are anatomical, physiological, developmental, immunological, and evolutionary units, evolved from a shared relationship between different species. We argue that many of the interactions between human and microbiota symbionts and the reproductive process of a new holobiont are best understood as instances of reciprocal scaffolding of developmental processes and mutual construction of developmental, (...) ecological, and evolutionary niches. Our examples show that mother, fetus, and different symbiotic microbial communities induce or constitute conditions for the development and reproduction of one another. These include the direct induction of maternal or fetus physiological changes, the restructuring of ecological relations between communities, and evolutionary selection against undesirable competitors. The mutual scaffolding and niche constructing processes start early—prior to amniotic rupture. We are evolutionarily, physiologically, and developmentally integrated holobiont systems, strung together through mutual reliance and mutual construction. Bringing the processes of niche construction and developmental scaffolding together to interpret holobiont birth conceptually scaffolds two new directions for research: in niche construction, identifying the evolutionary implications of organisms actively constructing multiple overlapping niches and scaffolds, and in Evolutionary Developmental Biology, characterizing evolutionary and ecological processes as developmental causes.

Denying special traits like the use of language to nonhuman animals has often been a basis for the creation of a stand-alone human sphere, apart from and above the animal world and the environmental milieu. Merleau-Ponty's phenomenology shows that human communication arises from the semiosis in the extra-human world and is not self-contained. Given many recent insights in scientific studies of nonhuman animals, only a few of which are cited here, it becomes impossible to say that animals are mute, (...) reactive entities. They too share many of the same features of communication with human beings. That said, articulating an interspecies ethic of sympathy or concern must take into account species and individual differences. (shrink)

Any biological species of biparental organisms necessarily includes, and is fundamentally dependent on, sign processes between individuals. In this case, the natural category of the species is based on family resemblances, which is why a species is not a natural kind. We describe the mechanism that generates the family resemblance. An individual recognition window and biparental reproduction almost suffice as conditions to produce species naturally. This is due to assortativity of mating which is not based on (...) certain individual traits, but on the difference between individuals. The biosemiotic model described here explains what holds a species together. It also implies that boundaries of a species are fundamentally fuzzy, and that character displacement occurs in case of sympatry. Speciation is a special case of discretisation that is an inevitable result of any communication system in work. The biosemiotic mechanism provides the conditions and communicative restrictions for the origin and persistence of diversity in the realm of living systems. (shrink)

Recent work has suggested that conservation efforts such as restoration ecology and invasive species eradication are largely value-driven pursuits. Concurrently, changes to global climate are forcing ecologists to consider if and how collections of species will migrate, and whether or not we should be assisting such movements. Herein, we propose a philosophical framework which addresses these issues by utilizing ecological and evolutionary interrelationships to delineate individual ecological communities. Specifically, our Evolutionary Community Concept recognizes unique collections of species (...) that interact and have co-evolved in a given geographic area. We argue this concept has implications for a number of contemporary global conservation issues. Specifically, our framework allows us to establish a biological and science-driven context for making decisions regarding the restoration of systems and the removal of exotic species. The ECC also has implications for how we view shifts in species assemblages due to climate change and it advances our understanding of various ecological concepts, such as resilience. (shrink)

Ape species-specific communication is grounded on the present, possesses some referential qualities and is mostly used to request objects or actions from others. Artificial systems of communication borrowed from humans transform apes' communicative exchanges by freeing them from the present (i.e. displaced reference) although requests still predominate as the main reason for communicating with others. Symbol use appears to enhance apes' relational abilities and their inhibitory control. Despite these substantial changes, it is concluded that even though artificial (...) communication enhances thought and enables its expression more openly, it does not create it or modify the motivation behind communicative exchanges.

Biodiversity informatics produces global biodiversity knowledge through the collection and analysis of biodiversity data using informatics techniques. To do so, biodiversity informatics relies upon data accrual, standardization, transferability, openness, and “invisible” infrastructure. What biodiversity informatics mean to society, however, cannot be adequately understood without recognizing what organizes biodiversity data. Using insights from science and technology studies, we story the organizing “visions” behind the growth of biodiversity informatics infrastructures in Sweden—an early adopter of digital technologies and significant contributor to global biodiversity (...) data—through interviews, scientific literature, governmental reports and popular publications. This case story discloses the organizational formation of Swedish biodiversity informatics infrastructures from the 1970s to the present day, illustrating how situated perspectives or “visions” shaped the philosophies, directions and infrastructures of its biodiversity informatics communities. Specifically, visions related to scientific progress and species loss, their institutionalization, and the need to negotiate external interests from governmental organizations led to unequal development across multiple infrastructures that contribute differently to biodiversity knowledge. We argue that such difference highlights that the social and organizational hurdles for combining biodiversity data are just as significant as the technological challenges and that the seemingly inconsequential organizational aspects of its infrastructure shape what biodiversity data can be brought together, modelled and visualised.

Communication Studies currently undergoes a crisis of paradigms that requires an ontological review that must begin with a debate about the conditions of possibility of every communicational phenomena. In this article we argue that semiosis offers a conceptual framework that allows for the study of communication as qualitative action. Semiosis, or the action of the sign, is here defined as a fundamental process based on perception that models the world of species, creating cognition and culture. At the (...) core of semiosis are dynamic structures that the authors have defined as ‘ontological diagrams’. The first purpose of Semiotics of Communication is to understand how these modeling systems evolve ontologically and phylogenically, producing, in the case of human culture, means of communication ever more varied and technologically advanced.

This paper examines recent communitarian writing about the market. Much of this work explains the loss of community in our times as a result of the expansion of the market and market values. As the market has invaded other domains, such as family andneighborhood, relationships there have become infected by the instability and transience that characterize market relations. Centralto this critique of the market is the view that the market is unable to sustain lasting commitments. This paper tests this hypothesis (...) byexamining the fate of the family—the paradigmatic case of commitment—in three separate historical periods when market orcommercial values were especially dominant. It then extends the analysis to two other component institutions of community—voluntaryand charitable activities. Finally, it examines institutions where so-called market values should presumably hold unchallenged sway,namely in the work place and the marketplace. The paper finds that communitarian values appear to thrive in market society. Instead ofbeing a juggernaut the market may be an endangered species. (shrink)

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