Populations of migratory birds are usually considered to be limited by conditions in breeding
or wintering areas, but some might be limited by conditions encountered on migration. This …

Unlike resident bird species, the population sizes of migratory species can be influenced by
conditions in more than one part of the world. Changes in the numbers of migrant birds …

Partial migration, where populations of animals are composed of a mixture of resident and
migratory individuals, is a widespread phenomenon in nature. It has been reported to occur …

This book meets the demand for a comprehensive introduction to understanding the
processes of population limitation. Recognized world-wide as a respected biologist and …

Identifying the factors that control population dynamics in migratory animals has been
constrained by our inability to track individuals throughout the annual cycle. Using stable …

The date when a landbird migrant arrives on its breeding grounds may have reproductive
consequences. Generally, early arriving individuals begin breeding earlier and …

Experimental estimates of the effects of selection on genes determining adaptive traits add
to our understanding of the mechanisms of evolution. We measured selection on genotypes …

In migratory birds, early arrival on breeding sites is typically associated with greater
breeding success, but the mechanisms driving these benefits are rarely known. One …

The phenomenon of bird migration has fascinated people from time immemorial. The
arrivals and departures of different species marked the seasons, heralding spring and …

Migratory birds are exposed to a diverse pathogen fauna by virtue of their long-distance
travels. Although the immune system is an organism's primary defense against pathogenic …
