Why wolves walk – drivers of daily movement in a social large carnivore
Wildlife Biology, EarlyView.Animal movement patterns are influenced by a range of extrinsic and intrinsic factors, including the distribution of resources, human disturbance, landscape connectivity, species interactions, and individual traits. We examined factors associated with daily movement distance (DMD) and linearity in 20 territorial Scandinavian wolves Canis lupus during ...

Are ground squirrels sleep deprived during hibernation?
, 1991 Hibernation is an adaptation for energy conservation, which probably evolved as an extension of non-rapid-eye-movement sleep mechanisms. Yet, during periodic arousals from bouts of deep hibernation, ground squirrels (Spermophilus lateralis) spend most ...

Alternative seed trait strategies are linked to a trade‐off between spatial and temporal dispersal
Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Seed dispersal allows plants to seek favourable conditions or spread the risk of unfavourable conditions through space and time. While theory predicts a trade‐off between spatial and temporal dispersal, empirical tests have been stymied by the difficulty of measuring ...

Convergent accelerated evolution of mammal-specific conserved non-coding elements in hibernators
Scientific ReportsMammals maintain their body temperature, yet hibernators can temporarily lower their metabolic rate as an energy-saving strategy. It has been proposed that hibernators evolved independently from homeotherms, and it is possible that the convergent ...

Biomolecules, 2019 Many studies have focused on how autophagy plays an important role in intestinal homeostasis under pathological conditions. However, its role in the intestine during hibernation remains unclear.

Elevated plasma phospholipid n-3 docosapentaenoic acid concentrations during hibernation.
PLoS ONE, 2023 Factors for initiating hibernation are unknown, but the condition shares some metabolic similarities with consciousness/sleep, which has been associated with n-3 fatty acids in humans.

Fungal Batrachochytrium dendrobatidis infections proliferate during amphibian terrestrial dormancy
Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract The spread and impact of wildlife pathogens is often seasonal, and identifying the season(s) of highest impact can be critical to biodiversity and public health management.

iScienceSummary: Amphibians, like the paddy frog (Fejervarya multistriata), have played a critical role in the transition from water to land. Hibernation is a vital survival adaptation in cold environments with limited food resources.

Journal of Animal Ecology, EarlyView.Migrating songbirds regularly use shallow torpor (up to 98% of birds for some species) to save energy (up to 42%) during inactive periods. This Ruby‐crowned Kinglet Corthylio calendula that was captured after a spring snowstorm highlights the value of being able to save energy when encountering unfavourable conditions.

H2S Induced Animation/hibernation–the Existence of Two Eukaryotic Metabolic States.
, 2017 Hibernation is a common metabolic state among many different groups of mammalians characterized by slow heart rate, decreased body temperature and reduced metabolic ...
