Treefrogs of the genus Osteocephalus have been the focus of several taxonomic and phylogenetic studies, especially in the last two decades. These recent studies have shown that the diversity of this charismatic Amazonian genus is still largely underestimated. Through the evidence of morphological and molecular data, we describe a new species of the Osteocephalus alboguttatus species group from the Purus-Madeira Interfluve, southwestern Brazilian Amazonia.

Es el resultado de un proyecto a raíz de conocerse la presencia de dos hongos patógenos, conocidos como hongos quitridios (‘Batrachochytrium dendrobatidis’ y ‘Batrachochytrium salamandrivorans’), que puede provocar la extinción de numerosas especies de anfibios a nivel mundial, en esta zona pirenaica, en altitudes más elevadas, según ha informado la UAB este martes en un comunicado.

En un nou article liderat pel Dr. Hugues-Alexandre Blain, publicat a la revista Archaeological and Anthropolocial Sciences, l’equip de Paleoherpetologia del IPHES-CERCA i l’Institut Reial Belga de Ciències Naturals estudiem l’evolució de les comunitats d’amfibis i rèptils de Bèlgica. Leer más.
Herpetofauna from 18 caves are described for the first time. In total, 17 taxa (10 amphibians and seven reptiles) are identified, three of which correspond to their first fossil record for Belgium (Alytes obstetricans, Pelobates fuscus, and Hyla arborea). The thermophilic snake Zamenis longissimus is documented for the first time in the Holocene (Atlantic/Subboreal period) of Belgium. After marine isotope stage (MIS) 5, the Belgian herpetofauna was still reasonably diverse during MIS 3, but it seems to be represented only by the common frog Rana temporaria and a viper during MIS 2.

We report the first cases of mortality in anurans associated with the presence of the fungus Batrachochytrium dendrobatidis at four different localities from Catalonia (NE Iberian Peninsula, Spain). All cases were confirmed by both molecular techniques and histology. The infected individuals were two Mediterranean painted frogs (Discoglossus pictus) from Girona province found in 2018 and 2020, one Iberian waterfrog (Pelophylax perezi) from Tarragona province found in 2018, and one European common frog (Rana temporaria) from Barcelona province found in 2019. This is the first time that mortality associated with this pathogen has been confirmed in D. pictus and P. perezi. Leer más.
