- W2765562664 abstract "Recent theoretical models predict that the evolutionary diversification of the weapons and ornaments of pre-mating sexual selection should be influenced by trade-offs with male expenditure on ejaculates. However, the patterns of association between secondary sexual traits and ejaculate expenditure are frequently inconsistent in their support of this prediction. We show why consideration of additional life-history, ecological, and mating-system variables is crucial for the interpretation of associations between secondary sexual traits and ejaculate production. Incorporation of these ‘missing variables’ provides evidence that interactions between pre- and post-mating sexual selection can underlie broad patterns of diversification in male weapons and ornaments. We call for more experimental and genetic approaches to uncover trade-offs, as well as for studies that consider the costs of mate-searching.

We call for more experimental and genetic approaches to uncover trade-offs, as well as for studies that consider the costs of mate-searching. Competition among males for access to mating opportunities is now widely recognized to drive the evolution of exaggerated secondary sexual traits. However, the role of post-mating competition for fertilizations in the evolution of weapons and ornaments has only recently been questioned. Male expenditure on both weapons and ejaculates is costly, and allocation trade-offs between secondary sexual traits and ejaculates are predicted to govern their joint evolution. Empirical support for this expected trade-off remains ambiguous. Consideration of additional ecological, life-history, and mating-system variables can reconcile inconsistent patterns of covariation between secondary sexual traits and ejaculate expenditure, and demonstrate that this trade-off can underlie broad patterns of divergence in weapons and ornaments.

Testes size is used as a shorthand for relative testes mass throughout the text. traits that bias mating success because their expression influences the outcome of male–male contests over access to females (weapons) or renders males more attractive to females (ornaments). differential reproduction arising from competition for mates and their gametes. competition between the sperm of two or more males over the fertilization of the ova of a female." @default.
