Behavioral ecology

Behavioral ecology is the study of the evolutionary basis for animal behavior due to ecological pressures. Behavioral ecology emerged from ethology after Niko Tinbergen outlined four questions to address when studying animal behavior which are the proximate causes, ontogeny, survival value, and phylogeny of behavior.If an organism has a trait which provides them with a selective advantage (i.e. has an adaptive significance) in a new environment natural selection will likely favor it. This was originally proposed as the theory of natural selection by Charles Darwin. Adaptive significance therefore refers to the beneficial qualities, in terms of increased survival and reproduction, a trait conveys. Genetic differences in individuals lead to behavioral differences that in turn drive differences in adaptation, reproductive success, and ultimately evolution.Individuals are always in competition with others for limited resources, including food, territories, and mates. Conflict will occur between predators and prey, between rivals for mates, between siblings, mates, and even between parents and their offspring.
