Sexual Selection's Effects on Male Life History and the Pattern of Male Mortality
Modifications of male life history due to sexual selection should be apparent in polygynous species such as elephant seals, in which sexual selection has produced a high degree of sexual dimorphism. In theory, male traits that confer a mating advantage bear survival disadvantage. The aim of this stu...
