The results indicate that cloacal temperature depends on the water temperature, corroborating the idea that C. asper is mainly a thermoconformer, as it corresponds to an aquatic ectotherm. However, the cloacal temperature of newts was slightly higher than water temperature. In individuals in amplexus, cloacal temperature was significantly higher than in specimens that are not in amplexus, and in July, females showed much greater dispersion in cloacal temperature than males, which is probably related to spawning behaviour.

While blood samples have been traditionally used, practical and ethical concerns have spurred exploration into minimally invasive media like saliva, feces, milk, hair, and feathers. Leer más.

We measured thermal heterogeneity in one of these ponds and discussed its relationship with development time and thermal tolerance in three observed species. Leer más.

Un equipo del CSIC consigue por primera vez tratar la quitidriomicosis, afección que diezma las poblaciones de anfibios, sin necesidad de retirar los animales del agua. Los investigadores aplicaron un fungicida agrario en el agua donde se reproducen los anfibios sin observar trazas del producto ni efectos significativos en la química y biología del agua. Leer más.

In this study, we used ecological niche models to evaluate which regions are more vulnerable to colonization by alien turtles and tortoises and which alien chelonians show substantial environmental overlap with native species.  Leer más.
