Document Summary
If selection favors males to mate with many females, how can monogamy evolve: h1 mate assistance. Males remain with one female because male parental care and protection of offspring are essential for reproductive success. Male-female partners become more efficient raising offspring with experience: h2 mate guarding. Males remain with one female because females are rare, receptive for only a short time, and/or widely dispersed: h3 mate enforced. Mates remain with one partner because the partner prevents him/her from mating with others: polygyny. What is the purpose of a lek: h1 female defense. Males defend multiple females by preventing access by other males. Effective only if females remain together and have reproductive synchrony: h2 resource defense. Males defend a rich patch of resources visited by multiple females. Effective only if nesting locations are limited and easily defended by a single male: h3 lek.
