Understanding the mechanisms that link ornamental displays and individual condition is key
to understanding the evolution and function of ornaments. Immune function is an aspect of …

Colourful ornaments often communicate salient information to mates, and theory predicts
covariance between signal expression and individual quality. This has borne out among …

Traditional models for female extra‐pair matings assume that females benefit indirectly from
extra‐pair mating behaviour. Under these so‐called adaptive models, extra‐pair males are …

Sexually selected traits are shaped by an interaction between sexual selection and other
natural selection pressures in the environment. However, there is little understanding of how …

Large structural variants in the genome, such as inversions, may play an important role in
producing population structure and local adaptation to the environment through suppression …

Improvement in reproductive performance with age, up to the point of senescence, is a
predominant pattern among vertebrates. Predictions from life‐history theory provide a …

Many species possess multiple sexual signals that are produced in different modalities.
Signals from different modalities may convey different or similar (redundant) information, or …

Male traits that signal health and vigour are used by females to choose better quality mates,
but in some cases the male trait selected by females differs among populations. Multiple …

In socially monogamous species, extra‐pair paternity may increase the strength of
intersexual selection by allowing males with preferred phenotypes to monopolize matings …

Hybrids with different combinations of traits can be used to identify genomic regions that
underlie phenotypic characters important to species identity and recognition. Here, we …
