Understanding speciation is one of the cornerstones of biological diversity research.
Currently, speciation is often understood as a continuous process of divergence that …

Understanding the processes and mechanisms that promote lineage divergence is a central
goal in evolutionary biology. For instance, studies investigating the spatial distribution of …

As DNA sequencing technologies and methods for delimiting species with genomic data
become more accessible and numerous, researchers have more tools than ever to …

We present genome assemblies for 18 snake species representing 18 families (Serpentes:
Caenophidia): Acrochordus granulatus, Aparallactus werneri, Boaedon fuliginosus …

Many phylogeographic studies on species with large ranges have found genetic–
geographic structure associated with changes in habitat and physical barriers preventing or …

The southeastern Nearctic is a biodiversity hotspot that is also rich in cryptic species.
Numerous hypotheses (eg, vicariance, local adaptation, and Pleistocene speciation in …

Recent studies found major conflicts between traditional taxonomy and genetic
differentiation of grass snakes and identified previously unknown secondary contact zones …

Using 12 microsatellite loci, mitochondrial DNA sequences and previously published
morphological evidence, we examined the phylogeographic and taxonomic structure of …

Abstract Aim The Nearctic is a complex patchwork of habitats and geologic features that form
barriers to gene flow resulting in phylogeographic structure and speciation in many …

Grass snakes are widely distributed across the Western Palearctic. Recent phylogeographic
studies provided evidence that three distinct parapatric species exist. Two of these occur in …
