Migratory birds regularly perform impressive long-distance flights, which are timed relative to
the anticipated environmental resources at destination areas that can be several thousand …

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 …

Differentiation between ecotypes is usually presumed to be complex and polygenic.
Seasonal patterns of life history in salmon are used to categorize them into ecotypes, which …

Although the migration ecology of birds breeding in the Neotropics is still poorly studied
relative to that of their counterparts breeding at north-temperate latitudes, studies conducted …

Species that hibernate generally live longer than would be expected based solely on their
body size. Hibernation is characterized by long periods of metabolic suppression (torpor) …

Timing is a crucial aspect for survival and reproduction in seasonal environments leading to
carefully scheduled annual programs of migration in many species. But what are the exact …

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 …

Bird migration has long been a subject of fascination for humankind and is a behavior that is
both intricate and multifaceted. In recent years, advances in technology, particularly in the …

Avian long-distance migration requires refined programming to orchestrate the birds'
movements on annual temporal and continental spatial scales. Programming is particularly …

Twice-a-year, large-scale movement of billions of birds across latitudinal gradients is one of
the most fascinating behavioral phenomena seen among animals. These seasonal voyages …
