The female reproductive tract is where competition between the sperm of different males
takes place, aided and abetted by the female herself. Intense postcopulatory sexual …

The handicap hypothesis of sexual selection predicts that sexual ornaments have evolved
heightened condition–dependent expression. The prediction has only recently been subject …

Why are most animal signals reliable? This is the central problem for evolutionary biologists
interested in signals. A number of theoretical answers have been proposed and empirical …

The last decade has witnessed considerable theoretical and empirical investigation of how
male sexual ornaments evolve. This strong male-biased perspective has resulted in the …

The genic capture hypothesis offers a resolution to the question of how genetic variation in
male sexually selected traits is maintained in the face of strong female preferences. The …

Mate choice is favored by indirect selection if choosy females mate with males of high
genetic quality. We believe, however, that testing hypotheses about indirect selection has …

META-ANALYSIS USES SUMMARY STATISTICS like effect sizes to combine information
from multiple studies. Yet a common problem encountered when collecting information for …

The elaboration and diversification of sexually selected weapons remain poorly understood.
We argue that progress in this topic has been hindered by a strong bias in sexual selection …

Theory suggests that the net benefit of allocating resources to a sexual trait depends both on
the strength of sexual selection on that trait and on individual condition. This predicts a tight …
