Behavioral Ecology

Behavioral ecology is the study of the evolutionary basis for animal behavior due to ecological pressures. It investigates how natural selection shapes behaviors—such as foraging for food, choosing mates, avoiding predators, and living in social groups—to maximize an organism's fitness, which is its ability to survive and reproduce. By examining the adaptive advantages of specific actions within an animal's physical and social environment, this field seeks to understand the ultimate, evolutionary reasons why animals behave the way they do, linking their actions to their success in a given ecosystem.
