AbstractEcology as a field produces philosophical anxiety, largely because it differs in scientific structure from classical physics. The hypothetical deductive models of classical physics are simple and predictive; general ecological models are predictably limited, as they refer to complex, multi-causal processes. Inattention to the conceptual structure of ecology usually imposes difficulties for the application of ecological models. Imprecise descriptions of ecological niche have obstructed the development of collective definitions, causing confusion in the literature and complicating communication between theoretical ecologists, conservationists and decision and policy-makers. Intense, unprecedented erosion of biodiversity is typical of the Anthropocene, and knowledge of ecology may provide solutions to lessen the intensification of species losses. Concerned philosophers and ecologists have characterised ecological niche theory as less useful in practice; however, some theorists maintain that is has relevant applications for conservation. Species niche modelling, for instance, has gained traction in the literature; however, there are few examples of its successful application. Philosophical analysis of the structure, precision and constraints upon the definition of a ‘niche’ may minimise the anxiety surrounding ecology, potentially facilitating communication between policy-makers and scientists within the various ecological subcultures. The results may enhance the success of conservation applications at both small and large scales.
