Calotriton arnoldi is an endemic amphibian inhabiting Montseny Natural Park and Biosphere Reserve (PNRBM), listed as “critically endangered (CR)” by IUCN. At the end of 2016, the Life Tritó del Montseny (LIFETM) project (LIFE15 NAT/ES/000757) was launched. The aim of the project was to promote around fifty actions to ensure the conservation of C. arnoldi and its natural habitat, and this entailed five strategic lines: Leer más.
Un estudio liderado por la Estación Biológica de Doñana del CSIC, ubicada en Sevilla, ha demostrado por primera vez que los cambios que realizan los organismos para ajustar su comportamiento, morfología y estrategia de vida a los cambios ambientales conllevan costes fisiológicos relacionados con el estrés oxidativo.

La contaminación del suelo por metales pesados contribuye a aumentar el estrés fisiológico de la culebrilla mora (Trogonophis wiegmanni), una especie de reptil adaptada a la vida subterránea, según un estudio científico. Leer más.
The fungal pathogen Batrachochytrium dendrobatidis (Bd) threatens amphibian biodiversity and ecosystem stability worldwide. Amphibian skin microbial community structure has been linked to the clinical outcome of Bd infections, yet its overall functional importance is poorly understood. Leer más.
Long-term maintenance of colour polymorphisms often depends on the interplay of multiple selective forces. In the common wall lizard (Podarcis muralis), up to three pure and two mosaic ventral colour morphs co-exist across most of its range. Available evidence suggests that colour morphs in this species are maintained through the interaction between sexual and environment-dependent selection. Leer más.
