:a branch of ecology concerned with the relationship between an animal's behavior and the conditions of its environment
- The more we came to know the behavioral ecology and vocalizations of one population of galago and moved on to the next, the more we realized that different species have been lumped together under the same name.

- Called behavioral ecology, it starts from the premise that social and environmental forces select for various behaviors that optimize people's fitness in a given environment.

- Finally, to complete this link between behavioral ecology and sociobiology, competitive interactions with other species are capable of constraining the social evolution of populations.
