This article discusses the possibility of ascribing intrinsic value to ecological systems. One way of talking about the intrinsic value of something is through its inherent characteristics. The concept of closure of constraints, which plays a central role in the organizational theory of ecological functions, allows us to claim ecological systems have inherent characteristics, namely, an intrinsic teleology and normativity. In this sense, ecological systems can be considered as having intrinsic value. However, this type of value is attributed to ecological systems by us, moral agents, as it would not be possible for something to have value exclusively in itself or independently of the relation with a value-ascribing agent. Thus, by asserting ecological systems have intrinsic value, we are regarding these entities as moral patients. Accordingly, we should take them into account and our moral consideration should go far beyond an anthropocentric perspective, opening the doors to an ecocentric ethics.

The livelihoods of fishing communities are entangled with global socio-environmental challenges such as climate change, declining fishing stocks, and ocean pollution. While these problems are global, they have heterogeneous local materializations that require interventions attuned to local contexts. This chapter discusses the struggles of three Brazilian artisanal fishing communities that live in distinct socio-environmental contexts, and their relations with transdisciplinary projects that highlight the importance of interventions aligned to local circumstances and expertise. While outlining a transdisciplinary approach that emphasizes bottom-up collaboration with local communities instead of top-down environmental governance, this chapter also points out the connections between local struggles that require coordinated action at regional, national, and international scales. Navigating between local and global challenges leads to a perspective of ‘multi-level governance’ that emphasizes the agency of communities while connecting contexts through mutual learning and through social movements that challenge external drivers of local struggles.

Based on a mixed-methods study involving triad tasks and ethnobiological models, we analyze local categories and knowledge of key ethnospecies of fish exploring partial overlaps between artisanal fishers’ and academic knowledge in a fishing community in northeast Brazil. We argue that fishers’ and academic knowledge overlaps may provide common ground for transdisciplinary collaboration, while their partiality requires reflection on epistemological and ontological differences. Here, we show how knowledge of artisanal fishers can complement academic knowledge and bring about tensions that need to be addressed through intercultural dialogue. By integrating a general philosophical framework of partial overlaps with a mixed-methods study on fishers’ knowledge, we show how ethnobiology can contribute to reflective and empirically-grounded transdisciplinary practices.

The concept of regulation is used in biology to explain properties such as stability, robustness, and long-term persistence of biological systems. Regulation claims often focus, however, on the capabilities of these systems, rather than the mechanisms underlying them. In an attempt to produce a full-fledged theoretical account of regulation, a stricter concept has been proposed by Bich and colleagues based on the theory of biological autonomy. According to these authors, regulation is exerted by specialized subsystems that can change the constitutive regime of a system (enabling it to deal with a wider range of perturbations) but whose dynamics are not specified by the latter. In this paper, we present a brief survey on how regulation has been treated in biology and, more specifically, in ecology. We show how the ecological literature attributes regulatory powers either to organismic phenomena or to the propagation of perturbations through the network of relations in ecological systems. We were not able to find any study proposing a specialized subsystem dedicated to regulation in an ecological system. This raises doubts about the feasibility of a regulatory subsystem such as conceived by Bich and colleagues. Nonetheless, we argue that ecological systems may encompass more than just dynamic stability and feedback mechanisms, such that it can be worthy applying their concept to investigate regulation in these systems.

Terms loaded with informational connotations are often employed to refer to genes and their dynamics. Indeed, genes are usually perceived by biologists as basically ‘the carriers of hereditary information.’ Nevertheless, a number of researchers consider such talk as inadequate and ‘just metaphorical,’ thus expressing a skepticism about the use of the term ‘information’ and its derivatives in biology as a natural science. First, because the meaning of that term in biology is not as precise as it is, for instance, in the mathematical theory of communication. Second, because it seems to refer to a purported semantic property of genes without theoretically clarifying if any genuinely intrinsic semantics is involved. Biosemiotics, a field that attempts to analyze biological systems as semiotic systems, makes it possible to advance in the understanding of the concept of information in biology. From the perspective of Peircean biosemiotics, we develop here an account of genes as signs, including a detailed analysis of two fundamental processes in the genetic information system (transcription and protein synthesis) that have not been made so far in this field of research. Furthermore, we propose here an account of information based on Peircean semiotics and apply it to our analysis of transcription and protein synthesis.

La idea según la cual el gen es una unidad estructural y funcional se ha visto cada vez más cuestionada a causa de descubrimientos realizados en investigaciones con eucariotas. Podemos clasificar los desafíos planteados a dicha idea en tres tipos: correspondencias uno-a-muchos entre segmentos de ADN y ARN/polipéptidos ; correspondencias muchos-a-uno entre segmentos de ADN y ARN/polipéptidos ; falta de correspondencia entre segmentos del ADN y ARN/polipéptidos . Sin embargo, incluso si, por estas razones , no sería realista buscar una definición única de gen, es de capital importancia que seamos capaces de formular diferentes definiciones conectadas entre sí teórica y operacional mente

Ethnobiology has become increasingly concerned with applied and normative issues, such as climate change adaptation, forest management, and sustainable agriculture. Applied ethnobiology emphasizes the practical importance of local and traditional knowledge in tackling these issues but thereby also raises complex theoretical questions about the integration of heterogeneous knowledge systems. The aim of this article is to develop a framework for addressing questions of integration through four core domains of philosophy - epistemology, ontology, value theory, and political theory. In each of these dimensions, we argue for a model of "partial overlaps" that acknowledges both substantial similarities and differences between knowledge systems. While overlaps can ground successful collaboration, their partiality requires reflectivity about the limitations of collaboration and co-creation. By outlining such a general and programmatic framework, the article aims to contribute to developing "philosophy of ethnobiology" as a field of interdisciplinary exchange that provides new resources for addressing foundational issues in ethnobiology and also expands the agenda of philosophy of biology.

No presente artigo, analisamos as abordagens de António Damásio e Gerald Edelman sobre a consciência e fazemos um paralelo com as teses apresentadas pelo filósofo John Searle. Recorremos também às críticas dos filósofos Bennett e Hacker como pedras de toque da viabilidade de algumas teses. Desse modo, apresentamos uma revisão sistemática da obra de Damásio, Edelman e Searle, a fim de promover um diálogo produtivo entre as ideias defendidas por estes autores, os quais, segundo nossa interpretação, assumem uma teoria do campo unificado da consciência

O discurso funcional é tanto ubíquo quanto central na ecologia contemporânea, principalmente no contexto das pesquisas sobre biodiversidade e funcionamento ecossistêmico, que emergiram nos anos 1990 em meio à crise da biodiversidade. Entretanto, a despeito dessa forte presença na ecologia, o discurso funcional ainda não tem sido investigado de maneira adequada nesta ciência, na medida em que muitos problemas fundamentais a respeito do tema ainda permanecem sem respostas claras. Por um lado, os ecólogos que lançam mão de explicações funcionais parecem simplesmente tomar como dado ou autoevidente o conceito de função. Contudo, ele nada tem de trivial, tendo em vista os problemas filosóficos suscitados pela linguagem funcional ou teleológica nas explicações biológicas, pelo menos desde Aristóteles. Por outro lado, poucos filósofos da ciência têm se mostrado especialmente interessados nos problemas epistemológicos associados ao discurso funcional em ecologia. Tomando essa situação como ponto de partida, nossa abordagem neste artigo se dá em três etapas. Inicialmente, procedemos a uma análise conceitual de função na ecologia atual, com ênfase nos estudos que relacionam a biodiversidade às propriedades ecossistêmicas. Esboçamos três significados principais do conceito, mostrando os pressupostos e as implicações associados a cada um deles. Num segundo momento, procedemos a uma análise das razões que levam a suspeitas ou objeções contra a linguagem funcional na ecologia. Por fim, num terceiro momento, lançamos algumas sugestões sobre como fundamentar ou dar mais clareza ao discurso funcional na ecologia contemporânea.

In the book The Insect Societies, Wilson proposed categories of sociality that were presented as a landmark unification of terminology in the study of social behavior. Since then, many new behavioral patterns have been described, but they could not be fitted into any of the available categories, undermining the consensus around that well-established classification. New general classifications tried to circumvent the limitations shown by Wilson’s categorization, but with little success. Among the proposals, some maintain the form of discrete categorization, while others advance a quantitative model to characterize sociality. These proposals have failed to clarify the use of the categories of sociality, and none of them has become widely accepted or overcome the problems faced by the classification of social behaviors. Here we explore whether an analysis of types of concepts proposed by Carnap can help to move forward in this discussion. His distinction between qualitative concepts and quantitative concepts is used here as an epistemological basis for analyzing the development of the proposed conceptual changes and classifications of sociality. Recently, social behavior has come to be considered a complex phenomenon, and quantitative concepts could bring a lot of informative data to understanding its development and perhaps its evolution. We conclude that a new metric of sociality should be built, using characteristics that are nonarbitrary, evolutionarily meaningful, and amenable to comparing all social animals. Finally, we advocate for an integrative view of social complexity based on individuals’ interactions as a useful metric of sociality. This approach still needs further development.

This article intends to show that the defense of “understanding” as one of the major goals of science education can be grounded on an anti-reductionist perspective on testimony as a source of knowledge. To do so, we critically revisit the discussion between Harvey Siegel and Alvin Goldman about the goals of science education, especially where it involves arguments based on the epistemology of testimony. Subsequently, we come back to a discussion between Charbel N. El-Hani and Eduardo Mortimer, on the one hand, and Michael Hoffmann, on the other, striving to strengthen the claim that rather than students’ belief change, understanding should have epistemic priority as a goal of science education. Based on these two lines of discussion, we conclude that the reliance on testimony as a source of knowledge is necessary to the development of a more large and comprehensive scientific understanding by science students.

Currently there are persistent doubts about the meaning and contributions of the gene concept, mostly related to its interpretation as a stretch of DNA encoding a single functional product, i.e., the classical molecular gene concept. There is, however, much conceptual variation around genes, leading to important difficulties in genetics teaching. We investigated whether and how conceptual variation related to the gene concept and gene function models is present in school science and what potential problems it may bring to genetics teaching and learning. Here, we report results on how ideas about genes and gene function are treated in textbooks and appear in students’ views and, also, about a teaching strategy for improving higher education students’ understanding of scientific models and conceptual variation around genes and their functions.

Cualquier descripción de la emergencia de significado en sistemas biológicos y artificiales debe apoyarse en un marco teórico que haga posible entender la naturaleza y la dinámica de tales procesos. En este artículo se toma la filosofía pragmática del signo de Charles S. Peirce, que asociamos aquí con el estructuralismo jerárquico de Stanley Salthe, como la base correcta para desarrollar ese marco conceptual. Se formulan algunas preguntas que consideramos fundamentales para asegurar una aplicación precisa de la noción de emergencia en el contexto de las investigaciones acerca de sistemas semióticos

This article addresses the contributions of the literature on the new mechanistic philosophy of science for the scientific practice of model building in ecology. This is reflected in a one-to-one interdisciplinary collaboration between an ecologist and a philosopher of science during science-in-the-making. We argue that the identification, reconstruction and understanding of mechanisms is context-sensitive, and for this case study mechanistic modeling did not present a normative role but a heuristic one. We expect our study to provides useful epistemic tools for the improvement of empirically-riven work in the debates about mechanistic explanation of ecological phenomena.

Transdisciplinary research challenges the divide between Indigenous and academic knowledge by bringing together epistemic resources of heterogeneous stakeholders. The aim of this article is to explore causal explanations in a traditional fishing community in Brazil that provide resources for transdisciplinary collaboration, without neglecting differences between Indigenous and academic experts. Semi-structured interviews were carried out in a fishing village in the North shore of Bahia and our findings show that community members often rely on causal explanations for local ecological phenomena with different degrees of complexity. While these results demonstrate the ecological expertise of local community members, we also argue that recognition of local expertise needs to reflect on differences between epistemic communities by developing a culturally sensitive model of transdisciplinary knowledge negotiation.

This paper offers a contribution to debates around integrative aspects of systems biology and engages with issues related to the circumstances under which physicists look at biological problems. We use oral history as one of the methodological tools to gather the empirical material, conducting interviews with physicists working in systems biology. The interviews were conducted at several institutions in Brazil, Germany, Israel and the U.S. Biological research has been increasingly dependent on computational methods, high-throughput technologies, and multidisciplinary skills. Quantitative scientists are joining biological departments and collaborations between physicists and biologists are particularly vigorous. This state of affairs raises a number of questions, such as: What are the circumstances under which physicists approach biological problems in systems biology? What kind of interdisciplinary challenges must be tackled? The paper suggests that, concerning physicists’ move to work on biological systems, there are common reasons to move, the transition must be understood in terms of degrees, physicists have a rationale for simplifying systems, and distinct conceptions of model and modeling strategies are recurrent. We identified problems regarding linguistic clarity and integration of epistemological aims. We conclude that cultural unconformities within the systems biology community have important consequences to the flow of scientific knowledge.

In this article, we draw upon the Conceptual Profile Theory to discuss the negotiation of meanings related to the energy concept in an 11th grade physics classroom. This theory is based on the heterogeneity of verbal thinking, that is, on the idea that any individual or society does not represent concepts in a single way. According to this perspective, the processes of conceptualization consist of the use of a repertoire of different socially stabilized signifiers, adjusted to the context in which they occur. We start by proposing zones of a conceptual profile model for energy, each zone being characterized by its own commitments and identifiable by certain modes of talking about energy. Based on classroom evidence, we claim that teachers and students negotiate meanings that interpenetrate the domains of everyday and scientific knowledge. Being inevitable and necessary, this heterogeneity of conceptual thinking needs to be considered in teaching design in order to allow its awareness on the part of the students. We argue that students’ conceptual development goals should be considered in terms of general goals of science education, which points to the need of overcoming the encapsulation of scientific school knowledge. We show that the Conceptual Profile Theory provides a basis for science education that can promote the crossing of cultural boundaries, seeking relations between science and the spheres of everyday life.

In many experimental sciences, like particle physics or molecular biology, the proper place for establishing facts is the laboratory. In the sciences of population biology, however, the laboratory is often seen as a poor approximation of what occurs in nature. Results obtained in the field are usually more convincing. This raises special problems: it is much more difficult to obtain stable, repeatable results in the field, where environmental conditions vary out of the experimenter’s control, than in the laboratory. We examine here how this problem affected an influential experimental research tradition in community ecology, the study of the ecology of the rocky seashores. In the 1960s, a handful of North-American ecologists, most notably Joseph Connell, Robert Paine and Paul Dayton, made the rocky seashores a model study system for experimenting in the field. Their experiments were deceptively simple: they removed species living on the seashore and described the resulting effects on the local ecology. These experiments exerted a deep influence on community ecology. They provided evidence for speculative developments concerning the theory of interspecific competition, the factors responsible for species richness and the ecology of food webs. They also stimulated novel conceptual developments. In particular, Paine developed the predation hypothesis, which states that the presence of predators can favour species richness, before introducing the keystone species concept, according to which some species exert disproportionate effects on ecological systems. More broadly, these experiments gave support to a methodological trend in favour of field experimentation. Only controlled perturbations in the field, it seemed, provided a reliable method to get insights into the structure of ecological communities. However, as experiments were continued in time and repeated in different sites, divergent results appeared. We analyse here how intertidal researchers coped with the variability of environmental conditions and tried to stabilize their results. In the process, they reconsidered not only their early conclusions, but also the exclusive status given to field experiments. Expanding on this case study, we discuss some significant differences between laboratory and field experiments.
