Abstract:Invertebrates are generally excluded from ethical consideration in scientific research and in environmental protection. In this paper I present and characterize controversies related to the use of freshwater benthic invertebrates in biological monitoring in the light of diverse ethical concepts. I consider the inherent contradictions which arise from simultaneously treating wild animals as: items possessing bio-indicative value, ecologically important elements of ecosystems, representatives of rare and endangered species and finally, as sentient beings with the capacity to suffer. The (...) analysis is based on numerical data collected during projects related to biological monitoring of Polish watercourses. Among the ethical concepts discussed, only the evolutionary inclusive one allows for a coherent classification of all animals according to the innate values assigned to individuals, and only this concept provides us with convincing arguments enabling the incorporation of individual invertebrates within the scope of ethical considerations.

The world’s oceans cover more than 70 per cent of the planet’s surface and contain 97 per cent of the water on planet Earth. Saltwater connects with freshwater with the outflow of every river and creek or from the drift of thunderstorms across islands to form new oceans. With a shared theme of water, recent projects are discussed as case studies for their focus on ecosystem awareness, cultural knowledge, arts and science and working collaboratively. Water is an essential element (...) and connector of ecosystems, species and spirituality – of life. The ability of water to change forms from liquid to solid to gas offers insights into acknowledging that changeability and adaptability are core to species survival on the planet Earth. It is proposed that by respecting the knowledge that is embedded in the element of water that greater wisdom can be shared which can benefit all life on this planet. With this aspiration in mind, the term OneWater is used to explore the relational aspect of water to consider its connective quality, between watersheds and species. This concept is used to shift views of anthropogenic impacts and embrace a fuller recognition of Indigenous knowledge systems and the role they play in evolving our understanding of the OneWater.

This article explores the early biogeographical debates that shaped the beginning of limnology, focusing on the differences of opinion concerning the origins of pelagic fauna between two pioneering scientists: Pietro Pavesi and François-Alphonse Forel. The study examines how Pavesi’s hypothesis of a marine origin for pelagic fauna contrasts with Forel’s theory of passive distribution, situating their arguments within a broader Darwinian framework. The first part of the paper provides a historical overview of Italian limnology, highlighting Pavesi’s contributions and interpreting Forel’s (...) writings to underscore the significance of discovering pelagic fauna in conceptualizing lakes as microcosms. The second part compares Pavesi’s and Forel’s hypotheses, emphasizing their impact on the scientific understanding of freshwater ecosystems. The importance of this discovery, in both historical and scientific contexts, lies in recognizing the presence of plankton in lakes as a crucial element for the mature formulation of ecological concepts, such as the ecosystem.

Predation and escaping from predation through hiding are two fundamental phenomena in ecology. The most common approach to reducing the chance of predation is to use a refuge. Here, we consider a three species fishery model system with prey refuge induced by a Holling type-II functional response. These three species of fish populations are named prey, middle predator, and top predator. Harvesting is employed in most fishery models to achieve both ecological and commercial benefits. Research proves that non-linear harvesting (Michaelis–Menten (...) type) returns more realistic outcomes. So, we have combined the Michaelis–Menten type of harvesting efforts for all populations. Uniform boundedness conditions for the solutions of the model are discussed. The existence conditions for possible equilibrium points with stability are presented. We explain the dynamical behavior at each equilibrium point through bifurcation analysis. The persistent criteria of the system are examined. Bionomic equilibrium and optimal harvesting control using Pontryagin’s maximum principle are calculated. For validation of the model in the real world, we have implemented this in the freshwater ecosystem of Lake Victoria. Extraction of native fish species and ecological balances are the foremost solicitude of Lake Victoria. We may resolve this concern partially by implementing prey refuge, since it may sustain the ecology of Lake Victoria, and therefore also its economical importance. Lake Victoria is acclaimed worldwide for the trade of fishing. Also, it provides the largest employment in east-central Africa and is beneficial to fishing equipment manufacturers. So, the bionomic equilibrium and harvesting control have significant applications in the fisheries. All the analytical studies are verified by numerical simulations. We have plotted phase portraits, bifurcation diagrams, Lyapunov exponents to explore the dynamics of the proposed model. (shrink)

The article discusses research conducted in a valuable biocoenosis in the Gnieźnieńskie Lakeland in central Poland. Protected within the Natura 2000 network, the area is simultaneously affected by climate change and anthropogenic pressures. The article suggests reconsidering the conservation site as engineered by the underwater stonewort meadows, rather than understanding it as an object managed by external experts. It is argued that a broader recognition of how the site is co-created and sustained through ecological processes, rather than solely through human (...) investments, fosters a sense of belonging and responsibility towards the environments that people share with others.

Aquatic ecosystems are vital to the structure and function of all environments on earth. Worldwide, approximately 95 million metric tons of fishery products are harvested from marine and freshwater habitats. A major problem in fisheries around the world is the bioethics of overfishing. A wide range of management techniques exists for fishery, managers and policy-makers to improve fishery production in the future. The best approach to limit overfishing is to have an effective, federally regulated fishery, based on environmental (...) standards and fishery carrying capacity. Soon, overfishing is more likely to cause fish scarcity than fossil fuel shortages and high energy prices for fish harvesting. However, oil and other fuel shortages are projected to influence future fishery policies and the productive capacity of the fishery industry. Overall, small-scale fishing systems are more energy efficient than large-scale systems. Aquaculture is not the solution to wild fishery production. The energy input/output ratio of aquacultural fish is much higher than that of the harvest of wild populations. In addition, the energy ratios for aquaculture systems are higher than those for most livestock systems. (shrink)

Recent data have provided evidence for an unrecognised ancient lineage of green plants that persists in marine deep-water environments. The green plants are a major group of photosynthetic eukaryotes that have played a prominent role in the global ecosystem for millions of years. A schism early in their evolution gave rise to two major lineages, one of which diversified in the world's oceans and gave rise to a large diversity of marine and freshwater green algae (Chlorophyta) while the other (...) gave rise to a diverse array of freshwater green algae and the land plants (Streptophyta). It is generally believed that the earliest-diverging Chlorophyta were motile planktonic unicellular organisms, but the discovery of an ancient group of deep-water seaweeds has challenged our understanding of the basal branches of the green plant phylogeny. In this review, we discuss current insights into the origin and diversification of the green plant lineage. (shrink)

Bioassessment is the process of using living organisms to assess the ecological health of a particular ecosystem. It typically relies on identifying specific organisms that are sensitive to changes in environmental conditions. Benthic macroinvertebrates are widely used for examining the ecological status of freshwaters. However, a time-consuming process of species identification that requires high expertise represents one of the key obstacles to more precise bioassessment of aquatic ecosystems. Partial automation of this process using deep learning-based image classification is the (...) goal of an ongoing project AIAQUAMI we are participating in. One of the project goals is to develop software support for image classification with visualization and reporting. For that purpose, we developed desktop and web applications that we open-sourced as Imagelytics Suite. Both desktop and web applications rely on a convolutional neural network (CNN) to classify images and the Grad-CAM algorithm to produce heatmaps of the image areas that mostly influenced the network decision. Along with the source code of the applications, we also open-sourced scripts that can be used to train CNN on an arbitrary dataset and produce required metadata, so it can be used with Imagelytics applications. In this article, we presented technical details regarding the design of the applications and the training method that will enable their general use for image classification tasks. As a part of the evaluation, we will show a use case related to species identification of non-biting midges (Diptera: Chironomidae). (shrink)

In this article, we will consider how the regulation of populations is not just a feature of prisons, but of all institutions and organisations that control members though hierarchies, divisions and norms. While nurses and other allied health professionals are considered to be predominantly self‐regulatory, practice is guided by a code of conduct and codes of ethics that act as rules that serve to uphold the safety of the patient, whether they are a sick person in a hospital bed or (...) an inmate in a prison. The codes of conduct espouse a number of rules that to a certain extent govern the behaviour of individual and groups of practitioners through reciprocal rewards and punishments. Supervision is one method of monitoring the effectiveness of the codes of conduct and ethics while regulating both the minimum standard of individual practice and of training organisations. It is posited that one of the possible effects of clinical supervision is to make the person effectively self‐regulatory as, an autonomous practitioner. We take the view that professional autonomy is a highly problematic concept requiring closer examination. (shrink)

Discourses of interdisciplinary health‐care are becoming more centralised in the context of global healthcare practices, which are increasingly based on multisystem interventions. As with all dominant discourses that are narrated into being, many others have been silenced and decentralised in the process. While questions of the nature and constituents of interdisciplinary practices continue to be debated and rehearsed, this paper focuses on the discourse of interdisciplinary collaboration using psychiatry as an example, with the aim of highlighting competing and alternative discourses. (...) The fundamental premise of this paper is that collaborative relationships form the basis of interdisciplinary practices in psychiatry. Through a critical engagement and a deconstructive reading of the pretext, context and subtexts of interdisciplinarity, we interrogate the concept of interdisciplinary practice within psychiatry. We contend that an important part of understanding and further conceptualising the discourse is through fracturing it. This process is illustrated in the successive stages of our conceptual map of discourse development: establishing, maintaining and developing discourses. An understanding of interdisciplinary practice is not only critical for psychiatry, but also offers important insights into the performance of collaborative failures and indeed successes across nursing and allied health professions.

This paper examines the distinction that is sometimes drawn between analysis and interpretation in the context of qualitative research, and the processes of critical analysis that underpin reflective practice. The authors consider the complementary logical processes involved in analysis and interpretation, and propose a cycle of reductive, inductive and hypothetico-deductive testing that is both rational and creative. The authors argue that the goal of critical reflection and qualitative data analysis is not to produce knowledge that can be justified in terms (...) of ‘correspondence’ to ‘reality’. Instead we propose a pragmatic, coherence view of knowledge that emphasizes the centrality of dialogue with texts, evidence, beliefs and practice. We conclude that evidence and belief are inextricably linked and that combined processes of reductive, inductive and hypothetico-deductive logic need to be used in a transparent manner to establish the credibility of an interpretation. Although there is no clear demarcation between what is found and what is constructed, a commitment to coherence is the basis of a pragmatic theory of knowledge. (shrink)

The concept of emotional intelligence has grown in popularity over the last two decades, generating interest both at a social and a professional level. Concurrent developments in nursing relate to the recognition of the impact of self‐awareness and reflexive practice on the quality of the patient experience and the drive toward evidence‐based patient centred models of care. The move of nurse training into higher education heralded many changes and indeed challenges for the profession as a whole. Traditionally, nurse education has (...) been viewed as an essentialist education, the main emphasis being on fitness for practice and the statutory competencies. However, the transfer into the academy confronts the very notion of what constitutes this fitness for practice.Many curricula now make reference in some way to the notion of an emotionally intelligent practitioner, one for whom theory, practice and research are inextricably bound up with tacit and experiential knowledge. In this paper we argue that much of what is described within curriculum documentation is little more than rhetoric when the surface is scratched. Further, we propose that some educationalists and practitioners have embraced the concept of emotional intelligence uncritically, and without fully grasping the entirety of its meaning and application. We attempt to make explicit the manner in which emotional intelligence can be more realistically and appropriately integrated into the profession and conclude by suggesting a model of transformatory learning for nurse education.

Our aim was to employ a critical analytic lens to explicate the role of nursing research in supporting the notion of caring realities. To do this, we used case exemplars to illustrate the infusion of such discourses. The first exemplar examines the fundamental concept of caring: using Florence Nightingale's Notes on Nursing, the case study surfaces caring as originally grounded in ritualized practice and subsequently describes its transmutation, via competing discourses, to a more holistic concept. It is argued that in (...) the many and varied attempts to define the dynamic concept of care, caring has now become paradoxically, a more fragmented concept despite attempts to render it more holistic and inclusive. In the second exemplar, one of the authors draws on her personal experience of the gap between theory and practice, so pronounced that it pushed the author to revisit the concept of evidence‐based practice and nursing education. In our third and final exemplar, we refer to the absence of knowledge and practice generated through natural enquiry and curiosity, an absence which has led to production of corporate led rhetoric. Drawing together the central arguments of the three exemplars, we reflect on the influential role of nursing research in enabling the deconstruction of taken for granted assumptions such as caring, evidence‐based practice and empowerment; assumptions which have been generated by discourses riddled with confusion and alienation from the reality of practice and the natural spirit of professional enquiry.

Many notions of interprofessional collaboration appear to aim for the ideal of trouble‐free co‐operative communication between healthcare professionals. This study challenges such an ideal as too far removed from the complex and contested relations of power that characterise the albeit skilful everyday social interactions which take place within healthcare practice, along with the associated pragmatic compromises made by disempowered practitioners. It is noted that these may be facilitated by modes of comforting myth and denial. To underline this point, psychiatric illness (...) diagnosis is used as an illustrative example of how a historically powerful societal discourse can become thoroughly entrenched. The influence of a paradigmatically dominant discourse is shown to extend beyond the repetition of narrative within open dialogue and debate and to continue as tacitly reflected patterns within unconsciously habituated behaviour and durable artefacts that crystallise future affordances and limitations on action. However, the authors conclude by introducing optimistic theoretical speculation around the dynamic social mechanics of reflexive awareness and creativity, as these emerge within moments of significant dissonance between dialectically interacting layers of individually internalised and contextually embedded discourse, conversation and direct experience.

Ecosystems services are provisions that humans derive from nature. Ecologists trying to value ecosystems have proposed five categories of these services: preserving, supporting, provisioning, regulating and cultural. While this ecosystem services framework attributes 'material' value to nature, sacred natural sites are areas of 'non-material' spiritual significance to people. Can we reconcile the material and non-material values? Ancient classical traditions recognise five elements of nature: earth, water, air, fire and ether. This commentary demonstrates that the perceived properties of these (...) elements correspond with the ecosystem services framework. Whilst the two can be reconciled, the 'elements of nature' framework is argued to be more suitable to make a case for conservation of sacred natural sites because it can be attractive to traditional societies whilst being acceptable to Western science.

Biologists employ a suggestive metaphor to describe the complexities of molecular interactions within cells and embryos: cytological components are said to be part of “ecosystems” that integrate them in a complex network of relations with many other entities. The aim of this essay is to scrutinize the molecular ecosystem, a metaphor that, despite its longstanding history, has seldom be articulated in detail. I begin by analyzing some relevant analogies between the cellular environment and the biosphere. Next, I discuss the (...) applicability of the molecular ecosystem concept in actual scientific practice. (shrink)

Some ecologists, philosophers, and policy analysts believe that ecosystem health can be defined in a rigorous way and employed as a management goal in environmental policy. The idea of ecosystem health may have something to recommend it as part of a rhetorical strategy, but I am dubious about its utility as a technical term in environmental policy. I develop several objections to this latest version of scientism in environmental policy, and conclude that our environmental problems fundamentally involve problems in our (...) institutions of governance, our systems of value, and our ways of knowing. These are the problems that most need to be addressed. (shrink)

The effects of climate change and increasing environmental pollution have clearly shown the vulnerability of individuals, local communities, and the natural environment, even in the Western context. However, despite such unquestionable data, International Law is still struggling to find adequate, unambiguous, effective solutions to the issue. Even the ‘human right to a healthy environment’, recognised by the UN General Assembly in 2022, is permeated by an anthropocentric idea of the world, which prevents it from fully dealing with ecosystem issues so (...) as to protect any living and non-living being. The paper starts by exploring the historical relevance of the concept of limit and the lack of boundaries in contemporary society, aiming to show that new semantics are needed, in order to overcome contemporary extractivism. An analysis of international legislation and jurisprudence will investigate the role that the concept of ecosystem vulnerability might play in the implementation of both human rights and the rights of nature.

Ecosystem services are the benefits people obtain from ecosystems. Many of these services are provided outside the borders of the land where they are produced. This article investigates who is entitled to these non-excludable ecosystem services from a libertarian perspective. Taking a right-libertarian perspective, it is concluded that the beneficiaries generally hold the right to use non-excludable ecosystem services and the right to landowners not converting ecosystems. Landowners are only at liberty to convert ecosystems if they appropriated (...) their land before any beneficiary used the services and converted the ecosystems before or shortly after the beneficiaries started using the services. This means that the beneficiaries generally hold the right to compensation payments by the landowners in the event of service losses, instead of the landowners holding the right to payments for ecosystem services by the beneficiaries. Taking a left-libertarian perspective, it is concluded that landowners ought to pay for the non-excludable ecosystem services lost as a result of their activities as well as beneficiaries paying for the non-excludable ecosystem services they use. These payments are not made mutually, however, but to a central authority that distributes the returns to the community on an equal per capita basis. (shrink)

The paper focuses on the semiotic principles of the organisation of ecosystems, attempting to find concepts that point to relations and not to elements. (1) Consortium (the term introduced by Johannes Reinke around 1873) can be defined as a group of organisms connected via (sign) relations, or groups of interspecific semiosic links in biocoenosis. The consortial relations include trophic and topic relations, both implying a recognition (identification) of the object by an organism involved (these, i.e., are sign relations). These (...) relations are ecologically inheritable. (2) Umwelt (the term introduced by Jakob von Uexküll around 1909) can be defined as a set of relations an organism has in an ecosystem (as in a semiosphere). The formation of an umwelt is dependent on the modelling system of the organism. (3) Biophony (the term introduced by Bernie Krause around 2000) denotes the coordination of inter- and intra-species relations in a soundscape of a biological community. This can be seen as a special case of Komposition as defined by Jakob and Thure von Uexküll. (4) Ecological code (as introduced, e.g. by Alexander Levich around 1977) can be defined as the set of (sign) relations (regular irreducible correspondences) characteristic to an entire ecosystem. We also mention the concepts of ecomones and coactones (introduced by Marcel Florkin in 1965) as the substances which are responsible for mediation of ecological inter-individual relations. All the relations as sign-relations evidently imply both a static or structuralist description (in terms of codes), and a processual description (in terms of semiosis carried on by interpretation). We conclude that all the above mentioned concepts can be viewed as conceptually connected and are suitable for semiotic description of biological communities. (shrink)

The article is devoted to the study of the history of the "innovation ecosystem" concept formation and provides a simplified schematic representation of the system as five interacting modules.

The attention of the academic and business communities representatives to the innovation ecosystems underlines the (...) fact that it is ecosystems and IT platforms that implement them that are the most promising candidates for the role of an organizational structure for the accumulation and scaling of new knowledge in the era of the industrial revolution.

The notion of entorno is discussed and its mutual dependence upon the organism is emphasised. Both the etymology and meaning of ethos, oikos, entorno and ecotomo are discussed. The intimate relation between Ethology and Ecology is also shown.

It is argued that the integrated concepts that originated the notion of ecosystem have been set aside. The term ecotomo (...) is proposed, which refers to any territorial unit that, considered at a local, regional or global level, emerges from the society-nature relationship. (shrink)

This paper argues that philosophers should pay more attention to the idea of ecosystem engineering and to the scientific literature surrounding it. Ecosystem engineering is a broad but clearly delimited concept that is less subject to many of the “it encompasses too much” criticisms that philosophers have directed at niche construction . The limitations placed on the idea of ecosystem engineering point the way to a narrower idea of niche construction. Moreover, experimental studies in the ecosystem engineering literature provide detailed (...) accounts of particular empirical situations in which we cannot neglect the O term in dE /dt = g (O, E), which helps us get beyond verbal arguments and simple models purporting to show that niche construction must not be ignored as a factor in evolution. Finally, this literature demonstrates that while ecosystem engineering studies may not require us to embrace a new evolutionary process, as niche construction advocates have claimed, they do teach us that the myriad abiotic factors concealed by the abstract term ‘environment’ are often controlled in large part by organisms.

I propose an ecologically attuned criterion for genuine virtue, namely, the criterion of ecosustainable virtue: a genuine virtue includes the goal of ensuring ecosystem sustainability. I show how this criterion emerges from environmental practice and how it can be supported by syllogistic reasoning.

In the US Environmental Protection Agency, the World Wide Fund for Nature and many other environmental organisations, it is standard practice to evaluate particular woods, wetlands and other such places on the basis of the ‘ecosystem services’ they are thought to provide. I argue that this practice cannot account for one important way in which places are of value to human beings. When they play integral roles in our lives, particular places have a kind of value which cannot be adequately (...) conceived in terms of service provision. Since it is in this respect limited, the ecosystem services framework can, I suggest, be criticised on grounds of justice. (shrink)

Arthur Tansley first defined the term ecosystem in his seminal work “Use and Abuse of Vegetational Concepts,” as an improved way of viewing the relationships between plants and their physical environments. However, his definition, while widely influential, privileges the living components over nonliving components of ecosystems, and has thus been unable to fully overcome the biocentrism of early plant ecologists. Moreover, the binary between life and nonlife is untenable, and serves only as a marker of the underlying biocentric values (...) of a researcher. Drawing from Donna Haraway’s argument for situated knowledges, one can critically examine the biocentrism implicit in much of ecology, and reconsider our definition of ecosystem in order to highlight our devaluation of the nonliving, and expand our normative universe.

Appeals to science as a help in constructing policy on complex issues often assume that science has relatively clear-cut, univocal answers. That is not so today in the environmentally crucial fields of ecology and evolutionary biology.

However, other more conscientious perspectives are now appearing within science, and we provide an example (...) here in rebuttal to the claim that there is no warrant from within ecology for ecosystem moral considerability.

The concept of ecosystem health is problematic. Do ecosystems as such exist? Is health an objective condition of organisms or is it socially constructed? Can 'health' be unequivocally predicated of ecosystems? Is ecosystem health both objective and valuative? Are ecosystem health and biological integrity identical? How do these concepts interface with the concept of biodiversity? Ecosystems exist, although they are turning out to be nested sets of linked process-functions with temporal boundaries, not tangible superorganisms with spatial boundaries. (...) Ecosystem health – or normal occurrence of ecological processes and functions – is an objective condition of ecosystems, although the concept of ecosystem health allows some room for personal and social determination or construction. Ecosystem health is prudentially, aesthetically, and intrinsically valuable, although the value of ecosystem health is subjectively conferred. Biodiversity and biological integrity are different from, but not unrelated to, ecosystem health. Together these three normative concepts represent complementary conservation goals. (shrink)

The notion of a spontaneous order has a long history in the philosophy of economics, where it has been used to advance a view of markets as complex networks of information that no single mind can apprehend. Traditionally, the impossibility of grasping all of the information present in the spontaneous order of the market has been invoked as grounds for not subjecting markets to central planning. A less noted feature of the spontaneous order concept is that when it is applied (...) to ecosystems it yields a reasonably strong environmental ethic. Thinking of ecosystems as spontaneous orders generates a presumption against interfering with their natural functioning in a manner that results in anthropogenic species loss. Such a presumption will permit some interventions in nature while precluding others. Environmental ethics could potentially make valuable use of the spontaneous order idea, without necessarily endorsing its traditional application to markets. (shrink)

This paper is a preliminary treatment of the categories of agency and dependence in the context of ecosystem services discourse. These categories are discussed in terms of critical categorial ontology in order to articulate adequately the nature of humankind’s dependence upon the nonhuman natural world, inadequately captured by ecosystem services discourse. Following Val Plumwood, this essay takes ecosystems services discourse as an example of one type of failure to discern various forms of agency as well as dependence, and it (...) goes on to define diffuse dependence as the relation that corresponds to the form of agency expressed through ecosystem services.

In France, the newly designed life and earth sciences programs for the Première Générale (second year of lycée) now include a segment dedicated to ecosystem services. The primary objective is to transition from an anthropocentric approach to an ecocentric approach, integrating the notion of ecosystem services (ES).

The analysis was (...) conducted using a corpus comprising life and earth sciences curricula, textbooks, and online resources, which unveiled diverse examples and materials pertaining to ES. The ensuing discussion emphasizes the need to embrace uncertainty and complexity in order to transcend a positivist rationalization of the human-nature relationship. (shrink)

In this article, I will discuss possible differences between ecosystems and organisms on the basis of their intrinsic complexity. As the concept of complexity still remains highly debated, I propose here a practical and original way to measure the complexity of an ecosystem or an organism. For this purpose, I suggest using the concept of logical depth (LD) in a specific manner, in order to take into account the difficulty as well as the time needed to generate the studied (...) object. I illustrate this method with fully controlled Daisyworld simulations (i.e., simulations based on the Gaia hypothesis) that have often been proposed to mimic living systems. The method consists of the following sequential stages: (1) identification of the shortest program able to numerically model the studied system (also called the Kolmogorov–Solomonoff complexity); (2) running the program, once if there are no stochastic components in the system, several times if stochastic components are there; and (3) computing the time needed to generate the system with LD complexity. This measure is supposed to estimate the system complexity. It appears in this study that LD estimations fit well with the intuition we have of complex systems, with higher complexities being found for more realistic Daisyworlds. With such a method of capturing the time needed to build a system, we expect to detect in future studies any quantified differences between complex ecosystems and organisms. (shrink)

Conflicts between science and religion revolve about fundamental assumptions more often than they do facts or theories. The key postulates that have guided science since the Enlightenment appear to be wholly inadequate to describe properly the development of ecosystems. An emended set of tenets adequate to the ecological narrative also significantly ameliorates the adversarial nature of the dialogue between scientists and theists.

Building upon a non-standard understanding of evolutionary process focusing on variation and persistence, I will argue that communities and ecosystems can evolve by natural selection as emergent individuals. Evolutionary biology has relied ever increasingly on the modeling of population dynamics. Most have taken for granted that we all agree on what is a population. Recent work has reexamined this perceived consensus. I will argue that there are good reasons to restrict the term “population” to collections of monophyletically related replicators (...) and interactors, which explains why many existing models in population biology exclude by definition many genuine evolving biological individuals such as communities and ecosystems. By studying a case of community evolution (a symbiotic termite–fungus community), we will see that it is variation that is important to evolutionary processes, not populations. Variation within a population is only one of many types of variation that can lead to evolution by natural selection. The upshot of focusing on variation is that cases of community and ecosystem adaptive change become tractable in evolutionary terms. I will show that complex emergent individuals such as communities and ecosystems cannot be fully accommodated by conventional population/reproduction models but can be accommodated by variation/persistence models.
