Sexual conflict occurs when the evolutionary interests of the sexes differ and it broadly
applies to decisions over mating, fertilization and parental investment. Recently, a narrower …

Understanding the role of multiple colour signals during sexual signalling is a central theme
in animal communication. We quantified the role of multiple colour signals (including …

Female mate choice is often based on exaggerated sexual traits, signals of male qualities
that females cannot assess directly. Two such key qualities are male immune and/or sexual …

Endocrine disrupting chemicals (EDCs) are chemicals that interfere with proper hormonal
functioning in exposed animals. They enter the natural environment through multiple …

Postcopulatory processes might play an important role in sexual selection. In theory,
fertilization success could be controlled by females via selection of particular sperm within …

Allocation trade-offs between the immune system and sexual traits are central to current
sexual selection hypotheses but remain contentious. Such trade-offs could be brought about …

Male mating signals, including ornaments and courtship displays, and other sexually
selected traits, like male-male aggression, are largely controlled by sex hormones …

Whether males can inseminate uncooperative females is a central determinant of mating
system evolution that profoundly affects the interpretation of phenomena such as multiple …

North Carolina, USA, represents the southern extent of the American black duck's (Anas
rubripes) breeding range. Mallards (A. platyrhynchos) are present on the breeding grounds …

Forced copulation is common, presumably because it can increase male reproductive
success. Forced extra-pair copulation (FEPC) occurs in birds, even though most species …
