Definition of Evolutionary ecology

Evolutionary ecology lies at the intersection of ecology and evolutionary biology. It approaches the study of ecology in a way that explicitly considers the evolutionary histories of species and the interactions between them. Conversely, it can be seen as an approach to the study of evolution that incorporates an understanding of the interactions between the species under consideration. The main subfields of evolutionary ecology are life history evolution, sociobiology (the evolution of behavior), the evolution of interspecific relations (cooperation, predator-prey interactions, parasitism, mutualism) and the evolution of biodiversity and of communities.
