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.

Journal of Fish Biology, EarlyView.Abstract Fewer than 50 of the over 30,000 extant species of fishes have developed anatomical specializations facilitating endothermy in specific body regions. The plankton‐feeding basking shark (Cetorhinus maximus), traditionally classified as an ectotherm, was recently shown to have regionally endothermic traits such as centralized red muscle (RM ...

Ecology and Evolution, Volume 16, Issue 8, August 2026.We evaluated adaptation to torpor and hibernation in the genus Dromiciops by comparing it with both torpid and non‐torpid marsupials, and investigated divergent selection signals between its two species. For the ancestral node, we identified positive selection in the genes PFKFB2, LAMP3, OTX1, and RAPSN, alongside an enrichment of pathways potentially ...

Heterothermy, and the Energetic Consequences of Huddling in Small Migrating Passerine Birds [PDF]
Integrative and Comparative Biology, 2011 The success of migration of small passerine birds depends largely on effective refueling at stopover sites. In our previous studies, we found that hypothermia facilitates accumulation of fuel at the beginning of a stopover. Later we found that blackcaps, Sylvia atricapilla, might further reduce their energy expenditure by huddling while at rest.

Global Change Biology, Volume 32, Issue 8, August 2026.Climate change is increasingly impacting arboreal mammals, yet these effects vary across regions and taxa, and global syntheses to inform conservation priorities remain limited. This study presents the first global synthesis of climate change impacts on arboreal mammals using a systematic review, meta‐analysis, and bibliometric analysis.

Migratory nightjars roost on asphalt to reduce thermoregulatory costs and increase fuel accumulation
Journal of Avian Biology, Volume 2026, Issue 4, July 2026.Migration is an energetically expensive event in the annual cycle of birds, requiring substantial fuel stores for successful completion. Optimizing fuel deposition rates benefits migrants, as faster fueling reduces the time required to store the necessary energy, maximizing overall migration speed.

Functional Ecology, Volume 40, Issue 7, Page 1960-1978, July 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Heatwaves are becoming increasingly frequent across the Mediterranean and pose critical challenges for small passerines, yet the physiological and morphological limits to their resilience remain poorly understood.

Biotropica, Volume 58, Issue 4, July 2026.ABSTRACT Species distributions are shaped by complex biotic and abiotic interactions, which are often not fully understood. We investigated the ecological basis of co‐occurrence and distribution of four partially sympatric and allopatric cryptic mouse lemur species (Microcebus spp.) in the Ambatosoa and Analanjirofo region of northeastern Madagascar ...

Locomotor Activity and Body Temperature Patterns over a Temperature Gradient in the Highveld Mole-Rat (Cryptomys hottentotus pretoriae). [PDF]
PLoS ONE, 2017 African mole-rats are strictly subterranean mammals that live in extensive burrow systems. High humidity levels in the burrows prevent mole-rats from thermoregulating using evaporative cooling.

Wildlife Letters, Volume 4, Issue 2, Page 66-72, June 2026.Tracking with GPS and accelerometers shows that great evening bats in subtropical China use two overwintering strategies: some remain in continuous hibernation, while others switch between torpor and activity as temperatures change. This behavioral flexibility, shaped by climate, underscores the importance of protecting diverse roosting habitats for ...
