The ecosystem of public parks often includes humans feeding the wildlife.
Functional ecology is the branch of ecology that focuses on the roles, or functions, that species play in the community or ecosystem in which they occur. In this approach, physiological, anatomical, and life history characteristics of the species are emphasized. It represents the true crossroads between ecological patterns and the processes and mechanisms that underlie them.
Functional ecology sits at the nexus of several disparate disciplines and serves as the unifying principle between evolutionary biology, genetics and genomics, and traditional ecological studies.
The scientific journal Functional Ecology is published by the British Ecological Society since 1987.
