Changes in community composition and functional diversity of European bats under climate change

Conservation Biology, Volume 39, Issue 4, August 2025.
Abstract Climate change is predicted to drive geographical range shifts that will result in changes in species diversity and functional composition and have potential repercussions for ecosystem functioning. However, the effect of these changes on species composition and functional diversity (FD) remains unclear, especially for mammals, specifically ...

Habitat dynamics of flagship species for conservation prioritization in southern Europe

Conservation Biology, Volume 39, Issue 4, August 2025.
Abstract Biodiversity loss is accelerating due to human actions, and decision‐making for conservation needs to be streamlined. Ex situ biodiversity modeling and monitoring based on satellite time‐series data could be an affordable and cost‐efficient tool for improving the prioritization of conservation areas.

Intraspecific variation and detectability of iridescence in the dorsal coloration of a wall lizard

Journal of Zoology, Volume 326, Issue 3, Page 239-255, July 2025.
Wall lizards (genus Podarcis) show substantial intraspecific colour variation and iridescence, which may interact and affect overall colour appearance. Here, we set out to study iridescence in Podarcis liolepis in two localities in which lizards are known to differ in dorsal coloration. Our results show that P.
