Delimiting and naming biodiversity is a vital step toward wildlife conservation and research.
However, species delimitation must be consistent across biota so that the limited resources …

The Sardinian grass snake, Natrix helvetica cetti, is an endangered endemic snake
subspecies with a restricted and highly fragmented geographic distribution. Information on …

Warm-adapted species survived the cold stages of the past glacial-interglacial cycles in
southern European peninsulas and recolonized major parts of Central and Northern Europe …

We used a dataset of georeferenced photos of 5,751 grass snakes from iNaturalist to
evaluate subspecific variation of Natrix natrix in coloration and pattern. Our results provide …

Using two mitochondrial DNA fragments and 13 microsatellite loci, we examined the
phylogeographic structure and taxonomy of two codistributed snake species (Natrix natrix …

This paper represents an update of the list of Italian amphibians and reptiles published 15
years ago by Razzettiet al.(2006) and of the checklist published in 1993 by the late …

An accurate species‐level taxonomy is paramount for biogeographical research, and
conversely, biogeographical data are of importance for species delimitation. We here review …

Genetic diversity feeds the evolutionary process and allows populations to adapt to
environmental changes. However, we still lack a thorough understanding of why hotspots of …

We scrutinize scientific names erected for or referred to Natrix astreptophora (Seoane,
1884), Natrix helvetica (Lacepède, 1789), and Natrix natrix (Linnaeus, 1758). As far as …

Over the past two decades, DNA barcoding has become the most popular exploration
approach in molecular taxonomy, whether for identification, discovery, delimitation, or …
