Sexual selection can explain major micro‐and macro‐evolutionary patterns. Much of current
theory predicts that the strength of sexual selection (i) is driven by the relative abundance of …

Data from avian species have played a prominent role in develo** and testing theories of
female mate choice. One of the most prominent models of sexual selection, the “good …

The study of sexual selection has traditionally focused on events and behaviours
immediately surrounding copulation. In this study, we examine whether carry-over effects …

In many species that form socially monogamous pair bonds, a considerable proportion of the
offspring is sired by extrapair males. This observation has remained a puzzle for …

Extra‐pair paternity (EPP) is a key aspect of the mating behaviour of birds and its frequency
varies widely among populations and species. Several hypotheses predict patterns of …

Many socially monogamous species paradoxically show signs of strong sexual selection,
suggesting cryptic sources of sexual competition among males. Darwin argued that sexual …

770—PeRSPectiveS in oRnitHology— auK, vol. 125 (2001: 39) stated that “while extra-pair
mating systems are the norm for temperate zone passerines, this is not true for tropical …

Comprehensive, accurate paternity assignment is critical to answering numerous questions
in evolutionary ecology. Yet, most studies of species with extra‐pair paternity (EPP) fail to …

Sexual selection is a fundamental evolutionary process but remains debated, particularly in
the complexity of polyandrous populations where females mate with multiple males. This …

Although sexual ornamentation mediates reproductive isolation, comparative evidence does
not support the hypothesis that stronger sexual selection promotes speciation. Prior …
