The very idea of novel ecosystems has been controversial in ecology. Critics have complained about its imprecision, and that it illicitly smuggles problematic ethical and political values into the science. By labelling a human-modified system a ‘novel ecosystem,‘ they worry, we give policymakers a “license to trash nature.“ The critics are right to be suspicious. I show that proponents of the novel ecosystem concept have been unable to make it both value-free and precise enough to allow for applied use.Also, the (...) critics are right to be suspicious, because a goal for many proponents of novel ecosystems is to bring new values into applied ecology. But the critics are wrong that this is illicit. I defend a value-laden conception of novel ecosystems, showing that applied ecologists are comfortable with other value-laden concepts, and that the value shift motivating discussion of novel ecosystems is necessary if we want to understand and protect nature in a changing world.

A recent article by Burch-Brown and Archer provides compelling arguments that biodiversity is either a natural kind or a pragmatically-valid scientific entity. I call into question three of these arguments. The first argument contends that biodiversity is a Homeostatic Property Cluster. I respond that there is no plausible homeostatic mechanism that would make biodiversity an HPC natural kind. The second argument proposes that biodiversity is a multiply-realizable functional kind. I respond that there is no shared function to ground this account. (...) The final, and strongest, argument, is that biodiversity is an ineliminable explanans and explanandum in various subdisciplines of biology. I argue that once we look at the details of the relevant research, not only does biodiversity in a broad sense not function in explanatory roles, but we must eliminate biodiversity in favor of more specific concepts in order to make sense of the leading explanations in contemporary ecology and conservation science.

The representation of a complex but stable, self-regulated and, finally, harmonious nature penetrates the whole history of Ecology, thus contradicting the core of the Darwinian evolution. Originated in the pre-Darwinian Natural History, this representation defined theoretically the various schools of early ecology and, in the context of the cybernetic synthesis of the 1950s, it assumed a typical mathematical form on account of α positive correlation between species diversity and community stability. After 1960, these two aforementioned concepts and their positive correlation (...) were proposed as environmental management tools, in the face of the ecological crisis arising at the time. In the early 1970s, and particularly after May’s evolutionary arguments, the consensus around this positive correlation collapsed for a while, only to be promptly restored for the purpose of attaching an ecological value on biodiversity. In this paper, we explore the history of the diversity–stability hypothesis and we review the successive terms that have been used to express community stability. We argue that this hypothesis has been motivated by the nodal ideological presuppositions of order and harmony and that the scientific developments in this field largely correspond to external social pressures. We conclude that the conflict about the diversity–stability relationship is in fact an ideological debate, referring mostly to the way we see nature and society rather than to an autonomous scientific question. From this point of view, we may understand why Ecology’s concepts and perceptions may decline and return again and again, forming a pluralistic scientific history. (shrink)

Biodiversity has become one of the most important conservation values that drive our ecological management and directly inform our environmental policy. This paper highlights the dangers of strategically appropriating concepts from ecological sciences and also of uncritically inserting them into conservation debates as unqualified normative landmarks. Here, I marshal evidence from a cutting-edge research program in microbial ecology, which shows that if species richness is our major normative target, then we are faced with extraordinary ethical implications. This example challenges our (...) well-received beliefs about biodiversity and it invites us to critically rethink the nature of this concept so that a more robust understanding of biodiversity and of its role in conservation policy could emerge.

The introduction of new genetic material into wild populations, using novel biotechnology, has the potential to fortify populations against existential threats, and, controversially, create wild genetically modified populations. The introduction of new genetic variation into populations, which will have an ongoing future in areas of conservation interest, complicates long-held values in conservation science and park management. I discuss and problematize, in light of genetic intervention, what I consider the three core goals of conservation science: biodiversity, ecosystem services, and wilderness. This (...) uneasy relationship, however, does not forgo the use of such interventions. I argue there is a case for the application of this technology within some interpretations of the moral frameworks of wilderness and biodiversity, despite apparent conflict between these values and the technology, and the possibility that this technology's use displays some limitations of the ecosystem services framework. Ultimately, the advent of biotechnology assisted restoration highlights the need for us to reevaluate our ethical concepts of conservation at times of global environmental and technological change.

Biodiversity is a key concept in the biological sciences. While it has its origin in conservation biology, it has become useful across multiple biological disciplines as a means to describe biological variation. It remains, however, unclear what particular biological units the concept refers to. There are currently multiple accounts of which biological features constitute biodiversity and how these are to be measured. In this paper, I draw from the species concept debate to argue for a set of desiderata for the (...) concept of “biodiversity” that is both principled and coheres with the concept’s use. Given these desiderata, this concept should be understood as referring to difference quantified in terms of the phylogenetic structure of lineages, also known as the ‘tree of life’. (shrink)

Nature-based solutions (NbS) have in recent years occupied a central position in conservation and climate discussions among both scientists and policy makers. NbS generally refer to a set of strategies which use nature, or natural objects, to address societal (human) issues while simultaneously supporting the broader environment. This paper examines the concept of NbS to determine whether it is a useful and well-motivated category to guide future climate and conservation efforts. I argue that NbS may in fact be a valuable (...) contribution to environmental thought and policy, but not for the reasons that they are typically thought to be. Specifically: while we have reason to doubt that NbS should be prioritized over other environmental strategies on the grounds that they are uniquely environmentally-friendly or supportive of biodiversity, they may nevertheless have an advantage insofar as they play a vital aesthetic role in developing a healthier relationship between humans and the nonhuman world.

Natural history specimens were collected for diverse reasons, but modern, and likely future, uses often diverge from why they were collected. For example, specimens are sometimes integrated into conservation decision-making, where some practitioners claim that specimens may be necessary or extremely important for conservation in general. This is an overstatement. To correct this, I engage with the current literature on specimen collection to show that while specimens have epistemic shortcomings, they can be useful for conservation projects depending on the questions (...) or values of scientists and conservation decision-makers. This modest approach acknowledges that specimens provide a unique information channel while demarcating where and when values intercede into conservation planning. In light of the specimen’s utility for future, sometimes unknown, projects, I also make recommendations for modern specimen collection. (shrink)

This paper explores interactions between ecological science and conservation values in the biodiversity-ecosystem function debate of the 1990–2000s. The scientific debate concerned the interpretation of observed correlations between species richness and ecosystem properties like primary productivity in experimental ecosystems. The debate over the causal or explanatory role of species richness was presumed to have implications for conservation policy, and the use of such research to support policy recommendations generated hostility between rival groups of ecologists. I argue that the debate was (...) due in part to the adoption of a broad conception of biodiversity as a goal and value in conservation politics and ethical debates, and the ecologists who questioned the causal efficacy of species richness were also suggesting problems with this goal. I characterize what I call the “uneasy consensus” established by BEF researchers in the late 2000s, discuss roles for values in BEF research, and suggest that this episode shows that ecological science can itself be an important site for ethical debates about conservation values.

In questo contributo di introduzione al volume “Biodiversity” (Rivista di Estetica n. 59, 2015), dopo aver sottolineato il legame tra la realizzazione degli inventari biologici (le tassonomie) e lo studio della biodiversità, e la difficoltà di definire la biodiversità, prendo in esame tre diversi modi di intendere il valore della biodiversità. Oltre al valore etico ed estetico, oggetto rispettivamente di discipline relativamente recenti come l’etica ambientale e l’estetica ambientale, la biodiversità ha un valore economico, presente soprattutto nel cosiddetto approccio dei (...) servizi ecosistemici, dove la biodiversità è principalmente intesa nei termini dei servizi che gli ecosistemi possono offrire agli esseri umani presenti e futuri.

The concept of biodiversity has played a central role within conservation biology over the last thirty years. Precisely how it should be understood, however, is a matter of ongoing debate. In this paper we defend what we call a classic multidimensional conception of biodiversity. We begin by introducing two arguments for eliminating the concept of biodiversity from conservation biology, both of which have been put forward in a recent paper by Santana. The first argument is against the concept’s scientific usefulness. (...) The other is against its value as a target of conservation. We show that neither of these objections is successful against the classic multidimensional conception of biodiversity. Biodiversity thus understood is important from a scientific perspective, because it plays important explanatory roles within contemporary ecology. Moreover, although it does not encompass all valuable features of the natural world, this does not show that we should abandon it as a target of conservation. Instead, biodiversity should be conceived as one of many grounds of value associated with ecosystems. This is consistent with concluding that a central aim of conservationists should be to protect biodiversity. (shrink)

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

In both scientific and popular circles it is often said that we are in the midst of a sixth mass extinction. Although the urgency of our present environmental crises is not in doubt, such claims of a present mass extinction are highly controversial scientifically. Our aims are, first, to get to the bottom of this scientific debate by shedding philosophical light on the many conceptual and methodological challenges involved in answering this scientific question, and, second, to offer new philosophical perspectives (...) on what the value of asking this question has been — and whether that value persists today. We show that the conceptual challenges in defining ‘mass extinction’, uncertainties in past and present diversity assessments, and data incommensurabilities undermine a straightforward answer to the question of whether we are in, or entering, a sixth mass extinction today. More broadly we argue that an excessive focus on the mass extinction framing can be misleading for present conservation efforts and may lead us to miss out on the many other valuable insights that Earth’s deep time can offer in guiding our future.

This paper addresses the stalemate on the question whether biodiversity has intrinsic value. I distinguish between a “weak” conception and two “strong” conceptions of intrinsic value in the environmental ethics literature. The strong conceptions of intrinsic value are connected, respectively, to moral standing and to a strongly objectivist account of value. Neither of these forms of value likely applies to biodiversity. However, the weak conception of intrinsic value is neutral about both moral standing and the nature of value and plausibly (...) applies to biodiversity. In addition, weak intrinsic value avoids common objections to the claim that biodiversity is intrinsically valuable. I develop a cumulative argument showing that environmentalists should presume that biodiversity has intrinsic value in the weak sense. (shrink)

Conservation biology emerged as an organized academic discipline in the United States in the 1980s though much of its theoretical framework was originally developed in Australia. Significant differences of approach in the two traditions were resolved in the late 1990s through the formulation of a consensus framework for the design and adaptive management of conservation area networks. This entry presents an outline of that framework along with a critical analysis of conceptual issues concerning the four theoretical problems that emerge from (...) it: (i) place prioritization for conservation action; (ii) the selection of surrogates for biodiversity in conservation planning; (iii) the assessment of vulnerability of conservation areas; and (iv) the synchronization of incommensurable criteria including socio-economic constraints on conservation planning.

I denna artikel kommer jag att ge en översikt över olika argument som ger stöd för slutsatsen att biologisk mångfald per se är värdefullt och bör bevaras. Ett vanligt argument vilar på premissen att biologisk mångfald har egenvärde, men premissen är svår att göra rimlig och får lätt kontraintuitiva följder. Utöver det kommer jag även att kritiskt granska instrumentella värden, relationella värden, och vad som här kallas ’miljöspecifika’ värden. I den sistnämnda kategorin ingår begrepp som naturlighet och naturvärde. Dessa definieras (...) ofta med ’frånvaro av avsiktlig mänsklig påverkan’ som ett nödvändigt villkor. Det kan finnas goda skäl att nyansera såväl instrumentellt värde som definitionen av naturvärde för att tillåta mänsklig påverkan som främjar biologisk mångfald utan att en värdeminskning sker.
