Declines were greatest for Epidalea calamita, followed by Pelobates cultripes, Triturus pygmaeus, and Lissotriton boscai. The mean number of species per sampling unit (i.e., grid cell) dropped from 4.3 to 3.1. To preserve Doñana’s amphibian community, it is important to restore the park’s pond network, which implies reducing regional groundwater overexploitation. Leer más.
The analysis of mitochondrial DNA indicated that the maternal lineage was unequivocally M. mutica (pure or hybrid), but nuclear DNA revealed a heterozygote position at the C-mos gene, matching sequences for this gene in GenBank from both M. leprosa and M. mutica. These results highlight the negative impact of alien turtles, which can genetically contaminate vulnerable native turtle populations. Leer más.

The results showed that individuals within the experimental group who experienced increased temperatures had significantly elevated dGC levels compared to the control animals. 
In turn, they also suggest that population differentiation in phenotypic traits associations might be a legacy of past biogeographic dynamics, identifying an overlooked driver of the current phenotypic architecture of animal populations. Leer más.
