Using genome-scale molecular datasets, the extent of admixture across hybrid zones can now be effectively assessed and the evolutionary independence of lineages inferred, leading to more reliable and comparable species delimitation criteria. Leer más.

Conservation planning in freshwaters should consider the dynamic effects of climate change and the ability of species to cope with it. In this study, we developed a framework for incorporating climate-driven dispersal barriers into conservation planning taking into account the medium and long-term impacts of climate change and species with obligatory interactions.

We present a taxonomic review and systematic revision of the Eyelash Palmitviper Bothriechis schlegelii (Berthold, 1846) based on examination of 400 museum specimens, a phylogeographic analysis of 818 locality records, and 80 individuals sampled for molecular characters. Leer más.

We describe a new species of the Scinax cruentomma species group, with a red streak in the iris and a weakly bilobate vocal sac. It is known from oligotrophic soils in the sedimentary basin of the Ucayali River near Jenaro Herrera (province of Requena, Peru) and Río Blanco (buffer zone of the Matses Indigenous territory and reserve).

Cold-blooded species that live in more temperate climates might fare better than tropical species as the planet warms, researchers found. They hope these findings can inform conservation efforts in the midst of climate change. Leer más.
