Abstract Animals have adapted behavioral and physiological strategies to conserve energy during periods of adverse conditions. Heterothermy is one such adaptation used by endotherms. While heterothermy—fluctuations in body temperature and metabolic

Abstract Background In highly seasonal environments, animals face critical decisions regarding time allocation, diet optimisation, and habitat use. In the Arctic, the short summers are crucial for replenishing body reserves, while low food availabili

Abstract For free-ranging animals living in seasonal environments, hypometabolism (lowered metabolic rate) and hypothermia (lowered body temperature) can be effective physiological strategies to conserve energy when forage resources are low. To what

Abstract Because of climate change, wildlife is facing altered environments, including profound shifts in temperature and precipitation regimes. In snow‐dominated ecosystems, winter warming and resulting changes in snowpack properties impact forage

Abstract Bio‐logging technology is now the golden standard for assessing how individual animals change their movement and behavior over time and space. Three‐dimensional accelerometer data, in particular, can provide extremely detailed informatio

The existence and persistence of rhythmicity in animal activity during phases of environmental change is of interest in ecology, evolution and chronobiology. A wide diversity of biological rhythms in response to exogenous conditions and internal stim

Instrumentation and sample collection for wildlife research and management may require chemical immobilisation of animals, which may entail physiological and behavioural effects on them. It is therefore important to evaluate the immobilisation protoc

Quantifying spatial and temporal variation in habitat suitability is crucial to understand changes in animal distribution and to inform conservation and management initiatives, especially for species occupying regions profoundly impacted by climatic

Hidden semi-Markov models generalise hidden Markov models by explicitly modelling the time spent in a given state, the so-called dwell time, using some distribution defined on the natural numbers. While the (shifted) Poisson and negative binomial dis

Snow and ice determine winter forage availability for Arctic herbivores. Winter precipitation is anticipated to increase, and icing following warm spells and rain-on-snow (ROS) are likely to become more frequent. While this may reduce herbivore survi
