Hotspots in Cold Climates: Mapping and Evaluating the Conservation of Winter Biodiversity Across the United States

open access: yesDiversity and Distributions, Volume 32, Issue 6, June 2026.
ABSTRACT Aim To identify hotspots and conservation priorities of biodiversity based on winter‐informed species distribution models for cold‐adapted mammals and birds, and their taxonomic, phylogenetic, and functional richness. Location The United States of America.

Beyond Temperature: Relative Humidity Systematically Shifts Juvenile Thermal Performance and Projected Population Growth in a Malaria Vector

open access: yesEcology Letters, Volume 29, Issue 6, June 2026.
Understanding how ectotherms respond to environmental change requires accounting for multiple interacting climatic factors; yet relative humidity is rarely integrated with temperature in trait‐based performance frameworks. Using laboratory experiments and an analytic population growth model, we show that humidity systematically modifies juvenile life ...

Beyond Bergmann and Allen: A Unified Framework for Thermoregulatory Morphology

open access: yesGlobal Ecology and Biogeography, Volume 35, Issue 6, June 2026.
ABSTRACT Context Ecogeographical rules such as Bergmann's and Allen's have long guided expectations about how organismal size and shape vary across temperature gradients. Yet these rules are typically tested independently despite sharing a common thermoregulatory basis.

Dehnel's Phenomenon in Mammals

open access: yesMammal Review, Volume 56, Issue 2, June 2026.
Some small mammals, which remain active year‐round, undergo reversible reductions in body size, braincase height, and the mass of internal organs, including the brain, from summer to winter. It is called Dehnel's phenomenon. In this review, we summarise knowledge of the mechanisms, adaptive value, and genetic basis of the phenomenon, and show how new ...

The Importance of Individual Body Condition in Mammalian Behavioural Responses to Disturbance

open access: yesMammal Review, Volume 56, Issue 2, June 2026.
Body condition, shaped by the balance between energy demands and reserves, predictably shapes mammalian disturbance responses. Poor‐condition individuals adopt needs‐based strategies, accepting greater risks to meet immediate energetic needs, while good‐condition individuals follow asset‐protection strategies, minimizing risks to protect their survival

Seasonal shifts in mitochondrial and reactive oxygen species metabolism are linked to ultrastructural remodelling in honey bees (Apis mellifera)

open access: yesThe Journal of Physiology, Volume 604, Issue 12, Page 4745-4770, 15 June 2026.
Abstract figure legend Seasonal changes profoundly reshape honey bee mitochondrial metabolism. In winter, bees shift from complex I (CI)‐ to mitochondrial glycerol‐3‐phosphate dehydrogenase (mG3PDH)‐ and complex II (CII)‐linked respiration. Despite lower CI‐linked respiration ATP production is maintained, suggesting increased energetic efficiency in ...

Annual assessment of Echinococcus multilocularis surveillance reports submitted in 2026 in the context of Commission Delegated Regulation (EU) 2018/772

open access: yesEFSA Journal, Volume 24, Issue 6, June 2026.
Abstract This report comprises the 16th assessment of the Echinococcus multilocularis surveillance scientific reports, provided by Finland, Ireland, United Kingdom (Northern Ireland) and Norway on their respective surveillance programmes. Every year since 2012, EFSA presents the assessment to the European Commission (EC) in which the sampling strategy,
