Investigadores del Museo Nacional de Ciencias Naturales (MNCN-CSIC) han analizado cómo la Sierra de Guadarrama condiciona la conectividad entre las poblaciones de cuatro anfibios ibéricos: la ranita de San Antonio, Hyla molleri, el sapo corredor, Epidalea calamita, la rana verde común, Pelophylax perezi, y el sapo de espuelas, Pelobates cultripes. El estudio, publicado en Journal of Biogeography, muestra que para el sapo de espuelas la sierra de Guadarrama supone una barrera difícil de superar, pero para el resto de especies actúa como un filtro semipermeable.

Following a request from EFSA, the Panel on Plant Protection Products and their Residues developed an opinion on the science to support the potential development of a risk assessment scheme of plant protection products for amphibians and reptiles. The coverage of the risk to amphibians and reptiles by current risk assessments for other vertebrate groups was investigated. Available test methods and exposure models were reviewed with regard to their applicability to amphibians and reptiles. Proposals were made for specific protection goals aiming to protect important ecosystem services and taking into consideration the regulatory framework and existing protection goals for other vertebrates. Uncertainties, knowledge gaps and research needs were highlighted. Ir al enlace.
