choice and intrasexual competition for mating opportunities—the standard forms of sexual …

For sexual selection to act on a given sex, there must exist variation in the reproductive
success of that sex as a result of differential access to mates or fertilisations. The …

Explaining the “prior-residence effect”(automatic owner status of individuals who arrived first
in an area) was one of the very first applications of game theory in animal behavior. These …

Kin selection can explain the evolution of cooperative breeding and the distribution of
relatives within a population may influence the benefits of cooperative behaviour. We …

Many studies have attempted to explain the evolution of cooperation, yet little attention has
been paid to what factors control the amount or kind of cooperation performed. Kin selection …

This study develops and tests an integrative model to better understand the mechanisms by
