Repeatability (more precisely the common measure of repeatability, the intra‐class
correlation coefficient, ICC) is an important index for quantifying the accuracy of …

Sexual selection plays several intricate and complex roles in the related processes of local
adaptation and speciation. In some cases sexual selection can promote these processes …

Research on mate choice has primarily focused on preferences for quality indicators,
assuming that all individuals show consensus about who is the most attractive. However, in …

Numerous studies have reported associations between heterozygosity in microsatellite
markers and fitness‐related traits (heterozygosity–fitness correlations, HFCs). However, it …

Female mate choice acts as an important evolutionary force, yet the influence of the
environment on both its expression and the selective pressures acting upon it remains …

The performance of courtship signals provides information about the behavioural state and
quality of the signaller, and females can use such information for social decision-making (eg …

Study of the genetic and developmental architecture of mate preferences lags behind the
study of sexual ornaments. This is in part because of the challenges involved in describing …

Birds are a particularly good group with which to examine the importance of maternal effects,
as parental contributions can be relatively easily quantified compared with other groups …

The maintenance of variation in sexually selected traits is a puzzle that has received
increasing attention in the past several decades. Traits that are related to fitness, such as life …

Animals are faced with many choices and a very important one is the choice of a mating
partner. Inter-individual differences in mating preferences have been studied for some time …
