Consulta de Difusion Veterinaria. 30(287):45-51. En la naturaleza, los cambios en el medio ambiente pueden modificar las dinámicas existentes entre huéspedes y patógenos, dando lugar a la aparición de enfermedades. En las últimas décadas, ha habido cambios ambientales que están afectando a los anfibios y la presencia y persistencia de ciertos patógenos. Leer más.
In this work, I tested these hypotheses on natterjack toads (Epidalea calamita). Specifically, I gauged activity time, exploratory behaviour and boldness in standard laboratory conditions, and assessed whether they correlated with body size and antipredator strategies, namely sprint speed, parotoid gland area and parotoid gland colour contrast.

Due to their assumed costs, simultaneous antipredator strategies are expected to face trade-offs, which, however, could be milder in individuals subjected to a more intense predator pressure. In this work, I studied the relationship between locomotion and parotoid glands in the natterjack toad, Epidalea calamita. Specifically, I predicted that individuals with reduced sprint speed would rely more on their chemical defences, having larger and more aposematically coloured parotoid glands. Leer más.
Emys orbicularis is a semi-aquatic turtle with great longevity being able to reach 50 years. In this study, we estimated the growth rates (in carapace length and body mass) in a population of E. orbicularis from the northeastern Iberian Peninsula over a period of 23 years. Leer más.
The slow-worm lizards (Anguis) comprise five species occurring throughout most of the Western Palearctic. Although these species are relatively uniform morphologically – with the exception of A. cephallonica, which exhibits a quite unique morphology – they are genetically deeply divergent. Leer más.
