Male-Male Competition: Competition between males for access to females.
Introduction
Contest competition in males (male-male competition) is a driving force in sexual selection (Puts 2010). For males, successful competitive displays increase access to valuable resources (e.g., territory, food), mates, and an increase in status. Some mechanisms favor success in male-male competition, such as aggressive behavior and physical characteristics that increase the facilitation of aggressiveness (i.e., size, strength, weaponry). For instance, sea lions establish their dominance through threats and fights, and this has important repercussions to their reproductive success. In a single breeding season, dominant males perform most of the copulations and sire a majority of pups (Daly and Wilson 1983). This intense competition between males was noted in Bateman’s classic 1948 study on sex differences in reproductive strategies using Drosophila...
