Zoologica Scripta, Volume 49, Issue 4, Page 395-411, July 2020., 2020 Abstract 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 Italy, Natrix helvetica and N. natrix, and a contact zone between both taxa has been suggested for north‐eastern Italy.

Colour polymorphism and conspicuousness do not increase speciation rates in Lacertids
Peer Community Journal, 2023 Conspicuous body colours and colour polymorphism have been hypothesized to increase rates of speciation. Conspicuous colours are evolutionary labile, and often involved in intraspecific sexual signalling and thus may provide a raw material from which ...
