Species‐level taxonomy derives from empirical sources (data and techniques) that assess
the existence of spatiotemporal evolutionary lineages via various species “concepts.” These …

Biodiversity analyses can greatly benefit from coherent species delimitation schemes and up-
to-date distribution data. In this article, we have made the daring attempt to delimit and map …

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 …

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

Palearctic water frogs (genus Pelophylax) are an outstanding model in ecology and
evolution, being widespread, speciose, either threatened or threatening to other species …

Species are the fundamental units of life and evolution. Their recognition is essential for
science and society. Molecular methods have been increasingly used for the identification of …

The advent of genomic methods allows us to revisit the evolutionary history of organismal
groups for which robust phylogenies are still lacking, particularly in species complexes that …

Chromosomal rearrangements can lead to the coupling of reproductive barriers, but whether
and how they contribute to the completion of speciation remains unclear. Marine snails of …

Animal translocations provide striking examples of the human footprint on biodiversity.
Combining continental-wide genomic and DNA-barcoding analyses, we reconstructed the …

As reflected by the two rules of speciation (Haldane's rule and the large X-/Z-effect), sex
chromosomes are expected to behave like supergenes of speciation: they recombine only in …
