male–male competition

in species in which the operational sex ratio leads to more reproductively active males than females, the rivalry that ensues as males compete over which will be able to mate with receptive females. In some species, such as cooperative-breeding mammals, male parental care is a limiting resource to female reproduction, and there is extensive female–female competition.
