Wildlife diseases are contributing to the current Earth’s sixth mass extinction; one disease, chytridiomycosis, has caused mass amphibian die-offs. While global spread of a hypervirulent lineage of the fungus Batrachochytrium dendrobatidis (BdGPL) causes unprecedented loss of vertebrate diversity by decimating amphibian populations, its impact on amphibian communities is highly variable across regions. Here, we combine field data with in vitro and in vivo trials that demonstrate the presence of a markedly diverse variety of low virulence isolates of BdGPL in northern European amphibian communities.

Many ectotherms modify their phenotype seasonally as a response to variation in abiotic factors. Given the potential of seasonal acclimation to reduce the impact of climate change on the dynamics of ectotherm populations, the adaptive evolution of this reversible plasticity has received much attention. Nevertheless, the key assumption of selection on the magnitude of seasonal acclimation, consistent among‐individual variation (repeatability), remains unexplored. Leer más.

 

Corría o mes de setembro de 2016 cando o grupo de estudo da sección galega da «Asociación Herpetológica Española» (AHE-Galicia) estaban a realizar unha nova mostraxe da herpetofauna da serra da Groba. O que podería ser un día máis de datos transformouse nun día memorable ao atopar un exemplar xuvenil de escáncer ibérico (Chalcides bedriagai), primeiro rexistro para a zona e realizado xusto onde hoxe queren plantar unha estación metereolóxica de 80 metros, xermolo do que será unha serie de muiños de producción eólica (até 44) que destrozarán os cumios da serra baixo o nome de Proxecto Albariño.
