USGS Changing Arctic Ecosystems: Response of Arctic breeding birds to climate-mediated changes on season length and food resources
This research will assess the effect of earlier springs on hatch date and food availability, and how this impacts growth and survival of juvenile birds.Abstract
Bird migration, breeding, and nesting are timed every spring to coincide with peak availability of critical food resources in a delicate balance that spans continents and diverse habitats. Birds that migrate to Arctic nesting grounds are predicted to be especially vulnerable to a phenological mismatch, which occurs when the timing of avian life events such as breeding no longer match peak food availability due to changes in climate. We will assess the vulnerability of Arctic-breeding migratory birds to mismatch scenarios by measuring variation in reproductive success, growth, and survival of young across the breeding season.
