Dispersal is a key demographic process involving three stages: emigration, transience and
settlement; each of which is influenced by individual, social and environmental …

The evolution of cooperation among animals has posed a major problem for evolutionary
biologists, and despite decades of research into avian cooperative breeding systems, many …

The Migration Ecology of Birds, Second Edition covers all aspects of this absorbing subject,
including migratory processes, problems of navigation and vagrancy, timing and …

Some individuals (helpers) in cooperatively breeding species provide alloparental care and
often suppress their own reproduction. Kin selection is clearly an important explanation for …

To select their future breeding site, individuals usually have to assess local quality by using
environmental cues. One optimal cue may be 'public information', the local reproductive …

Partial migration is common in ungulates living in highly seasonal environments. Typically,
at higher latitudes, this involves movement between high elevation summer areas used …

The evolution of cooperative breeding has been traditionally attributed to the effect of kin
selection. While there is increasing empirical evidence that direct fitness benefits are …

Ecology is a fundamental driving force for the evolutionary transition from solitary living to
breeding cooperatively in groups. However, the fact that both benign and harsh, as well as …

Billions of vertebrates migrate to and from their breeding grounds annually, exhibiting
astonishing feats of endurance. Many such movements are energetically costly yet there is …

The relative roles of ecological constraints, the benefits of philopatry, and the role of life
history continue to be debated in the evolution of natal philopatry and cooperative breeding …
