Every fall, millions of North American monarch butterflies undergo a stunning long-distance
migration to reach their overwintering grounds in Mexico. Migration allows the butterflies to …

Behavioral changes, such as those involved in mating, foraging, and migration, can
generate reproductive barriers between populations. Birds, in particular, are known for their …

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

Behavioral variation abounds in nature. This variation is important for adaptation and
speciation, but its molecular basis remains elusive. Here, we use a hybrid zone between two …

Seasonal migration is a taxonomically widespread behaviour that integrates across many
traits. The European blackcap exhibits enormous variation in migration and is renowned for …

Migration is a complex behavioural adaptation for survival that has evolved across the
animal kingdom from invertebrates to mammals. In some taxa, closely related migratory …

Seasonal journeys between breeding and non-breeding habitat are undertaken by a diverse
array of animals. Parallel developments in tracking and genomic methods are enabling finer …

The genetic architecture and neurogenetics of animal migration remain poorly understood.
With a sequenced genome and the establishment of reverse genetic tools, the monarch …

Structural variants (SVs) are a major source of genetic variation; and descriptions in natural
populations and connections with phenotypic traits are beginning to accumulate in the …

Wide-ranging animals, including migratory species, are significantly threatened by the
effects of habitat fragmentation and habitat loss. In the case of terrestrial mammals, this …
