Winter is a key driver of individual performance, community composition, and ecological
interactions in terrestrial habitats. Although climate change research tends to focus on …

Insect performance is limited by the temperature of the environment, and in temperate, polar,
and alpine regions, the majority of insects must face the challenge of exposure to low …

Freeze tolerance–the ability to survive internal ice formation–has evolved repeatedly in
insects, facilitating survival in environments with low temperatures and/or high risk of …

Freeze tolerance is an amazing winter survival strategy used by various amphibians and
reptiles living in seasonally cold environments. These animals may spend weeks or months …

Overwintering insects cannot feed, and energy they take into winter must therefore fuel
energy demands during autumn, overwintering, warm periods prior to resumption of …

Many environmental conditions can constrain the ability of animals to obtain sufficient food
energy, or transform that food energy into useful chemical forms. To survive extended …

For many terrestrial organisms in the Northern Hemisphere, winter is a period of resource
scarcity and energy deficits, survivable only because a seasonal refugium–the “subnivium” …

Temperate, polar and alpine insects generally do not feed over winter and hence must
manage their energy stores to fuel their metabolism over winter and to meet the energetic …

Thermal performance curves enable physiological constraints to be incorporated in
predictions of biological responses to shifts in mean temperature. But do thermal …

We investigated hibernation physiology and freeze tolerance in a population of the wood
frog, Rana sylvatica, indigenous to Interior Alaska, USA, near the northernmost limit of the …
