The distribution of crested newts in Serbia: an overview and update

Abstract

Four, morphologically similar species of crested newts (genus Triturus) meet and hybridize in Serbia, making a complex system with several hybrid zones. The puzzling and rapidly changing taxonomic status of crested newts has been a major issue in getting hold of their distribution. We provide an overview of the current knowledge on Triturus taxonomy and compile available faunistic data into a distribution map, highlighting the species contact and hybrid zones. At the present state of faunistic and genetic research, the north-western, north-eastern, eastern and south-eastern parts of Serbia transpire as areas that are exceptionally important for the diversity of crested newts.
