The functions of sleep remain elusive. Extensive evidence suggests that sleep performs
restorative processes that sustain waking brain performance. An alternative view proposes …

Recent advances in spring arrival dates have been reported in many migratory species but
the mechanism driving these advances is unknown. As population declines are most widely …

In seasonal environments, breeding events must be synchronized with resource peaks to
ensure production and growth of offspring. As changes in climate may affect trophic levels …

Under climate warming, migratory birds should align reproduction dates with advancing
plant and arthropod phenology. To arrive on the breeding grounds earlier, migrants may …

The ecological consequences of climate change have been recognized in numerous
species, with perhaps phenology being the most well‐documented change. Phenological …

Responses to climate change can vary across functional groups and trophic levels, leading
to a temporal decoupling of trophic interactions or “phenological mismatches.” Despite a …

Climate change may influence the phenology of organisms unequally across trophic levels
and thus lead to phenological mismatches between predators and prey. In cases where prey …

Intensification of agricultural use of grassland habitats has been linked to the declines of
many farmland bird species, several of whom have been in decline for multiple decades …

Abstract In environments such as arctic tundra, where bird densities are low and habitats are
comparatively homogeneous, suitable nest sites likely are not limited. Under these …

Previous studies have documented advancement in clutch initiation dates (CIDs) in
response to climate change, most notably for temperate-breeding passerines. Despite …
