During fieldwork, we discovered a new Rupirana species approximately 200 km beyond its known range. Previously, Rupirana had remained monotypic for over two decades, restricted to the campo rupestre ecosystem in the northern mountain ranges of Chapada Diamantina, Bahia. Leer más.
Ancient frog relatives survived the aftermath of the largest mass extinction of species by feeding on freshwater prey that evaded terrestrial predators, academics have found. Leer más.
C’est tout l’objet de la Stratégie nationale de gestion des amphibiens exotiques envahissants (SNG AEE) que la SHF a le plaisir de présenter aujourd’hui. Rédigée grâce à l’implication de nombreux experts, elle se concentre sur des problématiques émergentes connues en France hexagonale et concerne les quatre espèces les plus préoccupantes actuellement présentes sur ce territoire : la Grenouille taureau, le Xénope lisse, le Triton bourreau et le Sonneur à ventre de feu.

We discuss intrinsic and external mechanisms that may be contributing to fluorescence in the eggs, embryos, and larvae of salamanders. We also use previously published criteria to generate hypotheses about the potential ecological significance of fluorescence in the aquatic life history stages of salamanders. Leer más.
The species was identified phenotypically by the vertebral line of some individuals, which turned out to be an intrapopulationally polymorphic trait. A phylogenetic analysis with mitochondrial genes, including most of the species of the genus, showed that the discovered populations of A. vittatus are paraphyletic with respect to the only individual of A. neuquensis included.
