Spatial distribution-patterns on the Northern Dobrogean mainland () of the species belonging to ”green lizards” group of the Lacerta genus

Based on the results of field investigations carried out in 1994 – 2008 period, the author established the general distributional patterns in the northern part of the Dobrogean mainland of three lizard species. The Sand Lizards (Lacerta agilis) populates habitats with linear shape, the species being present along river valleys and some roads. The Balkan Green Lizards (L. trilineata) and the Green Lizards (L. viridis) were recorded mostly nearby or inside the forests (or plantations). In case of L. trilineata and L. viridis there is quite obvious the spatial segregation: in areas where the two species were present, the Balkan Green Lizard (L. trilineata) occurs mostly at lower altitudes, meanwhile the Green Lizard (L. viridis) was more frequently present at higher altitudes
