Aggregations (e.g. group basking) by snakes are usually limited to specific life cycle phases mating) or a consequence of drastic environmental changes habitat destruction), high prey densities highly resources within an environment basking sites, wintering dens). Here, we report intra- and interspecific observations four reptile species (primarily Natrix natrix Vipera berus ) sharing sites at ...

This work examined the enzymatic (superoxide dismutase-CuZn SOD, catalase-CAT, glutathione peroxidase-GSHPx, glutathione reductase-GR, and the biotransformation phase II enzyme glutathione-S-transferase-GST) and nonenzymatic (total glutathione-GSH and lipid peroxides-TBARS concentrations) biomarkers of oxidative stress and acetylcholinesterase (AChE) activity in the blood of the grass snake (Na...

The ongoing climate change and the unprecedented rate of biodiversity loss render need to accurately project future species distributional patterns more critical than ever. Mounting evidence suggests that not only abiotic factors, but also biotic interactions drive broad-scale patterns. Here, we explored effect predator-prey interaction on predator distribution, using as target widespread gener...
