Starting in 2010, rapid fire salamander (Salamandra salamandra) population declines in northwestern Europe heralded the emergence of Batrachochytrium salamandrivorans (Bsal), a salamander-pathogenic chytrid fungus. Bsal poses an imminent threat to global salamander diversity owing to its wide host range, high pathogenicity, and long-term persistence in ecosystems.  Leer más.


A disease that causes mass die-offs in frogs has been found in captive UK populations for the first time, scientists have warned. Severe perkinsea infection (SPI) has caused large tadpole mortality events across the US, and this is the first proof that its geographic range is spreading. Researchers also found the disease-causing microbe in wild and seemingly healthy populations in Panama, where some of the most rapid declines in frog populations globally have occurred. Leer más.


The Príncipe giant tree frog Leptopelis palmatus is endemic to the small oceanic island of Príncipe in the Gulf of Guinea. For several decades, this charismatic but poorly known species was confused with another large tree frog species from continental Africa, L. rufus. Phylogenetic relationships within the African genus Leptopelis are poorly understood and consequently the evolutionary history of L. palmatus and its affinity to L. rufus remain unclear. In this study, we combined mitochondrial DNA (mtDNA), morphological, and acoustic data for L. palmatus and L. rufus to assess different axes of divergence between the species. Leer más.
