The Allee effect describes a scenario in which populations at low numbers are affected by a
positive relationship between population growth rate and density, which increases their …

The evolution of group living remains an outstanding question in evolutionary ecology.
Among the most striking forms of group living are the enormous assemblages of breeders …

Allee effects are (broadly) defined as a decline in individual fitness at low population size or
density. They can result in critical population thresholds below which populations crash to …

In The Black-Tailed Prairie Dog, John L. Hoogland draws on sixteen years of research at
Wind Cave National Park, South Dakota, in the United States to provide this account of …

Habitat selection is a crucial process in the life cycle of animals because it can affect most
components of fitness. It has been proposed that some animals cue on the reproductive …

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 …

The quality of a bird's breeding site is a primary determinant of its success or failure to
reproduce there. We expect birds to devote considerable effort to acquiring accurate …

Classical models of breeding habitat selection rarely deal with the question of information
gathering for patch quality assessment. In this paper, we present two models comparing the …

The social environment is a critical determinant of fitness and, in many taxa, is shaped by an
individual's behavioral discrimination among social contexts, suggesting that animals can …

Seabirds comprise about 328 species in four orders, the Spenisciformes (penguins; 17
species in one family), Procellariiformes (albatrosses, shearwaters, petrels, diving petrels …
