Anisogamy
Divergence in size between male and female gametes

Fitness is limited by the available resources for males and by the number of assessable females for males
Behavioral ecology
The study of ecological and evolutionary basis for animal behavior, and the roles of behavior in enabling an animal to adapt to its environment
Behavioral polymorphism
Individuals of the same population show distinct behavior/strange patterns
Benefit and cost
Us economic approaches to analyze and show whether a certain behavior is adaptive when compared other alternatives
Brood parasitism

By-product mutualism
Cooperation in situations where there is no other alternative for their own benefit
Character displacement
Some characters show more dissimilar in the sympatric than the allopathic zones between two similar species

Cooperation
Two individuals behave beneficially to each other. It is the result of kin selection, reciprocal altruism, by-product mutualism, or group selection
