Abstract: A capture-mark-recapture investigations on two sympatric populations of Lacerta viridis and L. agilis has been carried out for a period of two years. Niche segregation has been studied from three main points of view: microhabitat, daily activity pattern and food selection. Schoener's measure of niche overlap was used in clarifying the roles of various factors. Food niche breadths of the two species has been described by an analysis of resource utilization curves. The following approximately equal in weight three factors are considered to be of greatest importance in the ecological segregation: 1. Microclimatic and activity pattern differences, 2. Prey taxa, and 3. Prey size.
