How individuals interact with their environment and respond to changes is a key area of
research in evolutionary biology. A physiological parameter that provides an instant proxy …

In this mini-review, we discuss how biologging technology can be used to detect,
understand, and forecast species' responses to climate change. We review studies of …

The first comprehensive review of all aspects of the biology of moult, drawing information
from across the literature and in all birds, from penguins to passerines. Feathers are …

Movement is energetically costly, requiring muscle activity to support and propel the animal
as it walks, runs, climbs, swims or flies. In this Review, I examine the metabolic impact of …

Background Optimal management of voluntary energy expenditure is crucial to the survival
and reproductive success of wild animals. Nevertheless, a growing appreciation of inter …

Ruminants living in seasonal environments face a two-fold challenge during winter. The
energetic cost of maintaining a high body temperature is higher at lower ambient …

Animals are expected to be judicious in the use of the energy they gain due to the costs and
limits associated with its intake. The management of energy expenditure (EE) exhibited by …

In a seasonal world, organisms are continuously adjusting physiological processes relative
to local environmental conditions. Owing to their limited heat and fat storage capacities …

Background The timing of autumn migration in ducks is influenced by a range of
environmental conditions that may elicit individual experiences and responses from …

Site fidelity is driven by predictable resource distributions in time and space. However,
intrinsic factors related to an individual's physiology and life-history traits can contribute to …
