Previous research has suggested that owners’ attitude to their family dogs may contribute to
a variety of behaviour problems in the dog, and authors assume that dogs with separation-…

The behavioural rhythms of organisms are thought to be under strong selection, influenced
by the rhythmicity of the environment 1 , 2 , 3 , 4 . Such behavioural rhythms are well studied …

Many shorebird species have widespread geographic distributions comprising several
continents. Because shorebirds are excellent flyers and can migrate large distances, it is often …

Background Parental care often increases offspring survival, but is costly to the parents. A
trade-off between the cost and benefit of care is expected, so that when care provisioning by …

The adult sex ratio (ASR) is a fundamental concept in population biology, sexual selection,
and social evolution. However, it remains unclear which demographic processes generate …

One of the most apparent examples of cooperation between unrelated individuals is
biparental care whereby the male and the female parent share the rearing of the offspring. …

Aim Parental care improves the survival of offspring and therefore has a major impact on
reproductive success. It is increasingly recognized that coordinated biparental care is …

Accurate estimates of annual survival are necessary for conservation of threatened species
of migratory birds. We studied a large, stable population of Kentish Plovers (Charadrius …

Gene flow promotes genetic homogeneity of species in time and space. Gene flow can be
modulated by sex‐biased dispersal that links population genetics to mating systems. We …

One of the fundamental insights of behavioural ecology is that resources influence breeding
systems. For instance, when food resources are plenty, one parent is able to care for the …
