Ecological niche models based on occurrence records of the amphibian chytrid fungus overestimate lethal chytridiomycosis risk

open access: yesJournal of Applied Ecology, Volume 62, Issue 4, Page 995-1006, April 2025.
Ecological niche models (ENMs) based on the presence data of Batrachochytrium dendrobatidis (Bd) can overestimate the mortality risk of chytridiomycosis because the environmental conditions suitable for Bd presence do not always correspond to those conducive to significant host mortality.

Environmental determinants of West Nile virus vector abundance at the wildlife–livestock interface Determinantes ambientales de la abundancia de vectores del virus del Nilo Occidental en la interfaz fauna‐ganado

open access: yesMedical and Veterinary Entomology, Volume 39, Issue 1, Page 200-215, March 2025.
Mosquito communities in southern inland Iberia are dominated by highly competent vectors of West Nile virus. The coexistence of Culex pipiens and Culex theileri in southern inland Iberia indicates that both species should be involved in West Nile virus transmission.

Reptile responses to fire across the western Mediterranean Basin

open access: yesConservation Biology, Volume 39, Issue 1, February 2025.
Abstract Effects of anthropogenic activities, including climate change, are modifying fire regimes, and the dynamic nature of these modifications requires identification of general patterns of organisms’ responses to fire. This is a challenging task because of the high complexity of factors involved (including climate, geography, land use, and species ...
