Conference Paper
Climate change would considerably influence survival of a species, especially of ectotherm ones such are snakes. We suppose that, if climate becomes warmer, both the costs and benefits of at least, thermoregulation would change for temperate-zone snakes. In modeling of the suitable habitats for Vipera ammodytes in central Serbia, we found that the...
Article
Insular populations offer excellent opportunities to study the factors that influence phenotypes. We observed island dwarfism in a widespread snake, the nose-horned viper (Vipera ammodytes). Island vipers were ~20% smaller than mainland individuals. They also produced fewer and smaller offspring. In snakes, food availability has a positive influenc...
Article
The smooth snake Coronella austriaca (Laurenti, 1768) is distributed across the western Palearctic throughout north‐central, southern Europe and western Asia. So far, only few phylogenetic studies, based on mitochondrial DNA, have been carried out on this species focusing mainly on the Iberian Peninsula and northern Europe, leaving unstudied some o...

Folk beliefs, religion and mythology, created through various cultural influences in Serbia, shaped today's attitudes toward wildlife. In this study we evaluated different levels of ecological awareness and superstition extent related to Hermann's tortoise (Testudo hermanni) through a systematized face-to-face questionnaire. The study was conducted...
Chapter
In these times of aggressive and enormous anthropogenic alterations of freshwater aquatic habitats throughout the Western Balkans, including drying out, pollution or the introduction of invasive species, the value of small water bodies (SWB) as refugia for local amphibians is clearly increasing. A network of SWB could be crucial for the conservatio...
Article
The slow-worm lizards (Anguis) comprise five species occurring throughout most of the Western Palearctic. Although these species are relatively uniform morphologically – with the exception of A. cephallonica, which exhibits a quite unique morphology – they are genetically deeply divergent. Here, we provide detailed distribution maps for each species...

The contemporary biodiversity crisis strongly impacts two groups of vertebrates: amphibians and reptiles. Amphibians face 40% of assessed species being in threatened IUCN categories, while reptiles are doing little better (34% of selected reptiles, e.g., marine turtles, sea snakes, chameleons, crocodiles and alligators). Adequate population studies...
