Global satellite-observed daily vertical migrations of ocean animals
Satellite-derived analysis of daily vertical migrations of ocean animals shows that the relative abundance and total biomass of these animals differ between different regions globally, depending on the availability of food and necessity to avoid predators.

Global spatial risk assessment of sharks under the footprint of fisheries
A global dataset of the satellite-tracked movements of pelagic sharks and fishing fleets show that sharks—and, in particular, commercially important species—have limited spatial refuge from fishing effort.

Breeding site sampling across the Arctic by individual males of a polygynous shorebird
Nomadic movement across the breeding range enables male pectoral sandpipers to display and sire offspring at multiple sites within a single breeding season, with tenure depending on breeding female numbers at each site.

The genetics of monarch butterfly migration and warning colouration
The monarch butterfly, well known for its spectacular annual migration across North America, is shown by genome sequencing of monarchs from around the world to have been ancestrally migratory and to have dispersed out of North America to occupy its current broad distribution; the authors also discovered signatures of selection associated with migration within loci implicated in flight muscle function, leading to greater flight efficiency.

Individual improvements and selective mortality shape lifelong migratory performance
A cross-sectional study of migrating raptors aged from 1 to 27 years old shows that migratory performance gradually improves with age and is driven both by selective mortality and individual improvement, with younger birds leaving progressively earlier as they age and becoming more proficient at coping with adverse environmental conditions, such as unfavourable winds.

Catching the wave
Observations of the migration patterns of Norwegian red deer show that some animals ride waves of greener vegetation as spring spreads across the landscape, whereas others jump ahead in anticipation of this higher-quality food.
