BACKGROUND Comparing patterns of terrestrial and marine defaunation helps to place
human impacts on marine fauna in context and to navigate toward recovery. Defaunation …

The three main energy-demanding events in the yearly cycles of birds—breeding, moult and
migration—tend to occur at different times of year from one another, with minimal overlap …

The exploration of animal migration has entered a new era with individual-based tracking
during multiple years. Here, we investigated repeated migratory journeys of a long-distance …

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