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 …

Hybridization as an evolutionary process has been studied in depth over the past few
decades. Research has focused on its role in shaping reproductive barriers, its adaptive …

Subdivided Pleistocene glacial refugia, best known as “refugia within refugia”, provided
opportunities for diverging populations to evolve into incipient species and/or to hybridize …

The radiation of Palearctic green toads (Bufotes) holds great potential to evaluate the role of
hybridization in phylogeography at multiple stages along the speciation continuum. With …

Identifying sources of genetic variation and reconstructing invasion routes for non‐native
introduced species is central to understanding the circumstances under which they may …

Despite increasing appreciation of the speciation continuum, delimiting and describing new
species is a major yet necessary challenge of modern phylogeography to help optimize …

The banded newt (genus Ommatotriton) is widely distributed in the Near East (Anatolia,
Caucasus and the Levant)–an understudied region from the perspective of phylogeography …

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 …

X chromosome was reported to be a major contributor to isolation between closely related
species—the 'large X'effect (LXE). The causes of LXE are not clear, but the leading theory is …

Species are fundamental units in many biological disciplines, but there is continuing
disagreement as to what species are, how to define them, and even whether the concept is …
