Understanding the factors that affect hybridization is an important issue in the study of
species evolution. In this work, we analyse the genetic structure of two lizard species …

When recently diverged taxa come into contact, the extent of introgression between them is
related to the degree of differentiation that they have achieved. Studying contact zones is …

Climate may play important roles in speciation, such as causing the range fragmentation that
underlies allopatric speciation (through niche conservatism) or driving divergence of …

Aim Diversification and rapid radiation are well documented in lacertid lizards. Niche
conservation is frequently observed among related taxa, whereby niches will not change …

Caucasian rock lizards (Darevskia) are a speciose group with 42 described species from the
Caucasus Mountain region. We selected 11 species from Georgia and adjacent territories to …

Aim The ocellated lizards of the genus Timon, comprising six species that are distributed
across continental Asia, Europe and Africa, offer an interesting model to study the evolution …

Population divergence and speciation are often explained by geographical isolation, but
may also be possible under high gene flow due to strong ecology‐related differences in …

We investigated two critical aspects of an animal invasion: the possibility of a genetic
bottleneck upon introduction, and microhabitat choice during the spread into a novel …
