Male contest competition and the coevolution of weaponry and testes in pinnipeds.

Evolution; international journal of organic evolution - 1 Nov 2012

Fitzpatrick John L, Almbro Maria, Gonzalez-Voyer Alejandro, Kolm Niclas, Simmons Leigh W

Abstract excerpt

Male reproductive success is influenced by competitive interactions during precopulatory and postcopulatory selective episodes. Consequently, males can gain reproductive advantages during precopulatory contest competition by investing in weaponry and during postcopulatory sperm competition by investing in ejaculates. However, recent theory predicts male expenditure on weaponry and ejaculates should be subject to...
