Here we provide a synthesis on the extent of Bd infection across South America based on 21 648 molecular diagnostic assays, roles of certain species in the epidemiology of Bd and explore its association with the reported amphibian catastrophic declines in the region. We show that Bd is widespread, with a continental prevalence of 23.2%.  Leer más.

Despite uncertainties in the absolute values of estimated abundance, the striking regional-scale decline of newts is evident. Among the major determinants of population dynamics, fish and crayfish presence increased their prevalence in the study area, while other factors remained more stable. Leer más.

Since the description of Charles Darwin’s frog as Rana charlesdarwini in 1998, its generic placement has been a taxonomic enigma. Subsequent studies first transferred this species to the dicroglossid genus Limnonectes, and then considered it as a ceratobatrachid of the genus Ingerana, which has since been moved to the family Dicroglossidae. However, recent works have doubted this generic placement and also suggested the possibility of its sister relationship with the genus Liurana, within Ceratobatrachidae. Leer más.

Una de les imatges més emblemàtiques de la natura al Montseny, és una salamandra fotografiada a la fageda de Santa Fe un dia plujós de primavera. Aquesta és l’espècie d’amfibi més abundant i àmpliament distribuïda al massís gràcies a l’abundant combinació de torrents i masses forestals que l’hi ofereixen ambients humits i temperats. Leer más.

The Filfil Slippery Frog lives amongst the rivers, streams, and large pools above 800 to 2500 meters above sea level. Not much is known about the frogs life history. Clusters of the eggs have been found at the end of the rainy season (August). Leer más.
