Migratory species are widespread in terrestrial, aquatic and aerial environments, and are
important both ecologically and economically. Since migration is an adaptive response to …

Animal migration has been the subject of intensive research for more than a century, but
most research has focused on long‐distance rather than short‐distance migration. Altitudinal …

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 …

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

Animal migration has long intrigued scientists and wildlife managers alike, yet migratory
species face increasing challenges because of habitat fragmentation, climate change and …

Migratory animals are predicted to enhance lifetime fitness by obtaining higher quality
forage and/or reducing predation risk compared to non‐migratory conspecifics. Despite …

Human‐induced changes in the climate and environment that occur at an unprecedented
speed are challenging the existence of migratory species. Faced with these new challenges …

Partial migration is widespread in ungulates, yet few studies have assessed demographic
mechanisms for how these alternative strategies are maintained in populations. Over the …

Elevational gradients provide powerful natural systems for testing hypotheses regarding the
role of environmental variation in the evolution of life‐history strategies. Case studies have …

Altitudinal migration is the seasonal altitudinal movement of birds from breeding areas to
non‐breeding or wintering areas at different elevations. Although this type of migration is …
