Abstract: Population dispersion of two sympatric lizard species, Lacerta viridis (Laur.) and L. agilis L., was calculated by Morista's index, indicating aggregated populations. Association values have been computed by three methods for the interrelationship between the two species, which has corroborated the distinctness between the lizard populations. Examining the relative growth of individuals, 2-variable discriminant analysis was performed for the quotiens tail length to total length and the tail length data. Generalized distance (D2) between the two populations was 0.4932. Of the various data collected in 1981, a morphological and a microclimatic variable group have been identified by principal component analysis. As a result of discriminant analysis performed for seven environmental variables, the measure of niche overlap between the two lizard species was found to be 34 percent.
