TL;DR: Across the radiation of Palearctic green toads, a stepwise progression of reproductive isolation through time is pinpointed, with a threshold below which hybridizability is irrespective of divergence, above which species barely admix and eventually evolve different mating calls, or can successfully cross-breed through allopolyploidization.

A new species of Leptopelis (Anura, Arthroleptidae) from the south-eastern slope of the Ethiopian Highlands, with notes on the Leptopelis gramineus species complex and the revalidation of a previously synonymised species.
TL;DR: A new ground-dwelling species of treefrog in the genus Leptopelis is described from the Harenna Forest in south-eastern Ethiopia as discussed by the authors.

TL;DR: This work analysed published mitochondrial and nuclear DNA sequences for this group of viperid snakes to reconstruct phylogenetic relationships among currently recognized viper species and compiled information on external morphology to assess their morphological distinctiveness.

Mitochondrial phylogeny shows multiple independent ecological transitions and northern dispersion despite of Pleistocene glaciations in meadow and steppe vipers (Vipera ursinii and Vipera renardi).

TL;DR: The phylogeny and historical demography of small Eurasian vipers of the Vipera ursinii and V. renardi complexes were studied and the high diversity of closely related haplotypes in the Caucasus and Tien-Shan could have resulted from repetitive expansion-constriction-isolation events in montane regions during Pleistocene climate fluctuations.

TL;DR: Based on the data gathered, and considering real and potential threats, global IUCN category Near Threatened is proposed for H. medicinalis, H. verbana, and H. orientalis, while H. troctina can only be assigned to category Data Deficient.
