Environmental Heterogeneity Generates Fluctuating Selection on a Secondary Sexual Trait

Robinson, Matthew R.; Pilkington, Jill G.; Clutton-Brock, Tim H; Pemberton, Josephine M; Kruuk, Loeske


In any population in which resources are limiting, the allocation of resources toward increased reproductive success may generate costs to survival [1-8]. The relationship between a sexually selected trait and fitness will therefore represent a balance between its relative associations with fecundity versus viability [3, 6, 7]. Because the risk of mortality in a population is likely to be heavily determined by ecological conditions, survival costs may vary as a function of the prevailing...[Show more]
