INTRASPECIFIC WING VARIATIONS IN ORTHETRUM BRUNNEUM (INSECTA: ODONATA): EFFECTS OF ANATOLIAN DIAGONAL

Abstract

Geographical and ecological diversity positively leads to variations in different populations of a species. In Turkey, researches on the effect of Anatolian diagonal with dozens of ecological barriers in terms of biodiversity, have been increased in recent years. The aim of this study is to determine the variations of wing morphologies of Orthetrum brunneum populations by using biometric characters. For this purpose, intra-species wing variations of three different Orthetrum brunneum populations were investigated where collected from Tunceli province located in east, Yozgat province located in west and Western Mediterranean Region located in south of Anatolian diagonal. Statistical analysis (Tukey HSD) showed that various biometric characteristics differed statistically among these taxon (P<0.05). According to Principal Component Analysis (PCA), four components with total variance Eigen value greater than 1 can be explained among these groups. Tunceli population were divergent from other populations by Discriminant Function Analysis (DFA). These findings support the idea that Anatolian diagonal is a barrier for populations of O. brunneum.
