Before dinosaurs walked the Earth, there was a meat-loving beast called Dimetrodon, which researchers just determined had the first known serrated “steak knife” teeth. Leer más.
We have updated the list of the lizard species present in Qatar and produced the first distribution maps based on two field surveys in 2012 and 2013. We used the QND95/Qatar National Grid with a grid of 10 × 10 km squares for mapping. Our results show the occurrence of 21 lizard species in Qatar, from the 15 species indicated in the last biodiversity report conducted in 2004. Leer más.
We investigated the herpetofauna of four forests, designated as Globally Significant Biodiversity Areas in the Western Region, Ghana. We recorded a total of 47 amphibian species, among them the first country records for the genera Acanthixalus andPhlyctimantis, as well as new taxa within the genera Arthroleptis and Astylosternus.

Higher-level systematics in amphibians is relatively stable. However, recent phylogenetic studies of African torrent-frogs have uncovered high divergence in these phenotypically and ecologically similar frogs, in particular between West African torrent-frogs versus Central (Petropedetes) and East African (Arthroleptides and Ericabatrachus) lineages.

In the present study, we use mtDNA sequence data (cyt b gene) in combination with nuclear DNA sequences (C-mos, Rag2 genes, R35 intron), nuclear genomic fingerprints (ISSR) and morphological data to reveal species diversity within the Southeast Asian leaf turtle genus Cyclemys, a morphologically difficult group comprising cryptic species.
