Winter conditions impose dramatic constraints on temperate, boreal, and polar ecosystems,
and shape the abiotic and biotic interactions underpinning these systems. At high latitudes …

The decision of when to breed is an important determinant of individual fitness. However,
despite a multitude of studies investigating the intraspecific relationship between timing of …

Microclimates play a prominent role in efforts to conserve species in the face of climate
change. However, climate-change research often relies on macroclimate data to predict …

Accurately determining the diet of wild animals can be challenging if food items are small,
visible only briefly, or rendered visually unidentifiable in the digestive system. In some food …

Climate change is having substantial impacts on organism fitness and ability to deliver
critical ecosystem services, but these effects are often examined only in response to current …

Weather conditions experienced by birds can influence their migration decision‐making and
strategy both within and across seasons. Additionally, decision‐making during migration …

Arctic and subarctic wildlife are among the most vulnerable species to climate change.
Canada Jays (Perisoreus canadensis (Linnaeus, 1776)) are generalist residents of northern …

The non-breeding distribution and ecology of many migratory songbirds are often poorly
studied, but very relevant for their conservation in a changing climate. The Snow Bunting is …

Breeding dispersal can influence fitness as well as the dynamics and genetic architecture of
populations, but the patterns and causes of dispersal in most species are still poorly …

High-elevation insectivorous birds are currently confronted with the reality of a changing
climate, land use shifts, and the decline of many prey groups. The diet dynamics among …
