Between primers, there were no significant differences in the diversity and richness of prey detected. We observed differences in the prevalence of prey identified between sampling regions both in our study and in other studies of S. salamandra diet. This COI metabarcoding study provides recommendations and resources for subsequent research using DNA metabarcoding to study amphibian diets. Leer más.
Un estudio realizado por investigadores de la UMA, del Museo Nacional de Ciencias Naturales (MNCN-CSIC) y de la Universidad Complutense de Madrid (UCM) muestra que la exposición de las larvas de rana verde común, Pelophylax perezi, al amonio, presente en muchos fertilizantes utilizados en agricultura, reduce la capacidad del sistema inmune de los machos adultos para responder a las infecciones.

Our results show that artificial sites are preferentially used as breeding sites in the region compared to natural aquatic habitats, providing key habitat for the species and hosting much larger numbers and densities of larvae than natural sites. At local scale, populations of A. obstetricans in artificial sites were abundant and characterized by high male breeding success. Leer más.
The Iberian northwest was predicted to capture adaptive range for most species. My study offers analytical guidelines for managers and decision makers to undertake systematic assessments on where and when to intervene to maximize the persistence of amphibian species and the functionality of the ecosystems that depend on them.

Our data allow hypothesizing that the Iberian Peninsula might harbor the ancestral population of CMTVs that could have spread into the rest of Europe. In addition, we found that climate warming could be triggering the CMTV outbreaks, supporting its endemic status in the Iberian Peninsula. Leer más.
