From the red grouse to the Ethiopian bush-crow, bird populations around the world can
provide us with vital insights into the effects of climate change on species and ecosystems …

In the current era of rapid climate change, populations are facing environments in which
food availability can quickly decline or become highly unpredictable. These conditions may …

Biomedical researchers have long appreciated that maternal stressors can induce
preparative and adaptive programming in offspring via exposure to maternal Glucocorticoids …

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 …

The seasonal timing of lifecycle events is closely linked to individual fitness and hence,
maladaptation in phenological traits may impact population dynamics. However, few studies …

Aerial drones are increasingly being used as tools for ecological research and wildlife
monitoring in hard-to-access study systems, such as in studies of colonial-nesting birds …

Optimality theory predicts that both timing of arrival and arrival state on the breeding area
will determine reproductive timing and investment in migratory organisms. We tested this …

Although physiological traits and phenology are thought to be evolved traits, they often show
marked variation within populations, which may be related to extrinsic factors. For example …

Seasonal declines in breeding performance are widespread in wild animals, resulting from
temporal changes in environmental conditions or from individual variation. Seasonal …

Animals must balance various costs and benefits when deciding when to breed. The costs
and benefits of breeding at different times have received much attention, but most studies …
