There is a long history of controversy in ecology over the role of competition in determining patterns of distribution and abundance, and over the significance of the mathematical modeling of competitive interactions. This paper examines the controversy. Three kinds of considerations have been involved at one time or another during the history of this debate. There has been dispute about the kinds of regularities ecologists can expect to find, about the significance of evolutionary considerations for ecological inquiry, and about the (...) empirical credentials of theoretical studies of competition. Each of these elements is examined with an eye toward gaining philosophical clarification of the issues involved. In the process, certain shortcomings of contemporary philosophical theories are revealed. In particular, I argue that plausibility arguments based on background considerations are an important part of the model building tradition, but that current accounts of the structure and evaluation of scientific theories do little to illuminate this side of theoretical ecology.

Philosophical analysis of ecological theories has lagged behind the study of evolutionary theory. The semantic conception of scientific theories, which has been employed successfully in the analysis of evolutionary theory, is adopted here to analyse ecological theory. Two general problems in ecology are discussed. One arises from the continued use of covering law models in ecology, and the other concerns the applicability of ecological theory in conservation biology. The semantic conception of ecological theories is used to resolve these problems.

El objetivo principal de este artículo se encuentra orientado a elucidar, desde una perspectiva histórica, cierta influencia que la problemática ambiental tuvo sobre la ecología disciplinar. Para ello, se analizó el periodo que va de la década de 1960 hasta la actualidad. Dos resultados centrales se desprendieron del análisis propuesto y ambos se encontraron mediados por un saber ambiental que emergió junto a la problemática ambiental. El primero, constata una serie de transformaciones fenomenológicas (con el establecimiento de nuevos patrones ecológicos), (...) epistemológicas (con la incorporación de la noción de escala y de la teoría jerárquica) y metodológicas (con la consolidación de los experimentos de mensuración) sobre la matriz de la ecología. El segundo, se vinculó con una continuidad sincrónica entre la problemática ambiental y la ecología disciplinar. Continuidad rastreada por el reconocimiento de una problemática ambiental de orden global. The main objective of this article is to elucidate, from a historical perspective, the influence that environmental issues have had on the discipline of ecology. To this end, the period from the 1960s to the present was examined. The proposed analysis revealed two main results; both were found to be mediated by environmental knowledge that emerged along with environmental issues. The first refers to a series of phenomenological (establishing new ecological patterns), epistemological (incorporating the notion of scale and hierarchical theory) and methodological (consolidating of experiments involving measurements) transformations over the ecology matrix. The second was linked with a synchronic continuity between environmental issues and the discipline of ecology. This continuity was traced by the recognition that environmental issues have global impact. (shrink)

A key challenge in conceptualizing ecological complexity is to allow simultaneously for particularity, contingency, and structure, and for such structure to be internally differentiated,dynamically tied to its context, and subject torestructuring. Because all organisms live insuch dynamic ecological circumstances, philosophy of ecology could become the leading site for addressing difficult conceptual questions concerning the situatedness or positionality of organisms –humans included – in their changing and intersecting worlds.

This paper uses structural analogies to competing political philosophies of human society as a heuristic tool to differentiate between ecological theories and to bring out new aspects of apparently well-known classics of ecological scholarship. These two different areas of knowledge have in common that their objects are ‘societies’, i.e. units composed of individuals, and that contradictory and competing theories about these supra-individual units exist. The benefit of discussing ecological theories in terms of their analogies to political philosophies, in this case (...) liberalism, democratism and conservatism, consists in the fact that political philosophies show clear differences and particularities as regards their approach to the concepts of individuality and intentional action. The method therefore helps to expose peculiarities of ecological theories that are usually considered canonical, as well as hybrid forms, and to differentiate between two different types of theories about functional wholes. The basis of this method is the constitutional-theoretical premise that modern paradigms of socialization structure the ecological discourse. (shrink)
