Males and females often exhibit different behaviours during mate acquisition, pair‐bonding
and parenting, and a convenient label to characterize these behaviours is sex role. The …

Maternal effects, or the influence of maternal environment and phenotype on offspring
phenotype, may allow mothers to fine‐tune their offspring's developmental trajectory and …

The behavioural rhythms of organisms are thought to be under strong selection, influenced
by the rhythmicity of the environment,,,. Such behavioural rhythms are well studied in …

Seasonal declines in breeding performance are widespread in wild animals, resulting from
temporal changes in environmental conditions or from individual variation. Seasonal …

It is often claimed that pair bonds preferentially form between individuals that resemble one
another. Such assortative mating appears to be widespread throughout the animal kingdom …

King rails experience a wide range of temperatures during the course of the breeding
season throughout their rapidly contracting geographic range. Incubating parent birds are …

Chronobiological research has seen a continuous development of novel approaches and
techniques to measure rhythmicity at different levels of biological organization from …

Most birds incubate their eggs to allow embryo development. This behaviour limits the ability
of adults to perform other activities. Hence, incubating adults trade off incubation and nest …

In biparental species, conflict between the sexes is expected when optimal levels of parental
care differ between males and females. We studied food provisioning in house wrens …
