In this work, we provide an overview of the age determination methods of amphibians and reptiles, critically evaluating their methodological principles, utility (including range of applicability), as well as experimental and biological limitations. Leer más.
This study presents the first comprehensive atlas of the distribution of amphibians and reptiles within the Moroccan section of the Intercontinental Biosphere Reserve of the Mediterranean (IBRM). Data were gathered from literature reviews, museum collections, and extensive field surveys conducted between 2008 and 2019. Leer más.
El biólogo asturiano David Martínez Viejo emprende en los próximos años una investigación que puede esclarecer mucho la huella que el cambio climático deja realmente en la naturaleza. Ha empezado a desarrollar su tesis doctoral en la Universidad de Oviedo estudiando la vulnerabilidad de los anfibios ibéricos frente al cambio climático mediante trabajo de campo, laboratorio y modelos predictivos.
