A link between increased temperature and avian body condition in a logged tropical forest

open access: yesConservation Biology, Volume 40, Issue 3, June 2026.
Abstract The combined effects of anthropogenic disturbances, such as logging and climate change, remain poorly understood; yet, they are the main threats to tropical biodiversity. Most tropical African countries lack long‐term climate data, so climate impacts on biodiversity cannot be assessed.

Biodiversity‐driven spatial conservation planning to delineate temporally stable regions

open access: yesConservation Biology, Volume 40, Issue 3, June 2026.
Abstract The accelerating loss of biodiversity underscores the critical need for effective conservation strategies, particularly in the face of climate change and anthropogenic pressures. We devised a conservation planning framework that adopts a temporal stacking approach to species distribution models and landscape connectivity analyses. These models

Local climate and genetic influence on intraspecific variation in torpor physiology of a cave‐roosting bat

open access: yesFunctional Ecology, Volume 40, Issue 4, Page 857-867, April 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Many small endotherms employ torpor as a survival strategy to reduce energy expenditure during periods with low food availability and cold temperatures. The expression and physiology of torpor can vary substantially within species because of phenotypic plasticity and ...

Representativeness of the Natura 2000 network for preserving plant biodiversity in the European Union

open access: yesConservation Biology, Volume 40, Issue 2, April 2026.
Abstract The Natura 2000 (N2K) network of protected areas is one of the main tools for area‐based conservation in the European Union (EU), yet its role in preserving plant biodiversity requires better understanding. We examined data kept in the European Vegetation Archive from over 1.2 million vegetation plots and obtained over 14.2 million plant ...

Use of a Cytobrush for Sampling the Ear Canal of Dogs With Otitis Externa

open access: yesVeterinary Dermatology, Volume 37, Issue 2, Page 227-235, April 2026.
Cytological examination of the ear canal is essential for evaluating dogs with otitis externa (OE). The conventional sampling method uses a swab. However, the cytobrush (gynaecological cervical brush), already used for cytological collection from other anatomical sites, has not been adequately investigated for this purpose in dogs with OE.
