Behavioral ecology is a branch of ecology that deals with the study of behaviors of animals on the basis of evolution. The behaviors studied in this are due to ecological pressures. Natural selection favors such a trait or characteristic of an organism that provides it with a selective advantage within its environment.
The selective advantage is also known as the adaptive significance and it refers to the expression of that particular trait which influences the fitness and it is measured by the success of an individual’s reproduction. The individuals of a population are always in competition with each other for resources such as food, mates, habitat, etc.
