A research of intra-species wing variations in Orthetrum brunneum (Fonscolombe, 1837) (Insecta: Odonata)

ABSTRACT Geographical and ecological diversity positively affect in-species diversity in different populations of the same species. Dozens of a ecological barrier, especially in Turkey to investigate the effect of Anatolia Diagonale terms of biodiversity has increased in recent years. The aim of this study is to determine the variations of wing morphology of Orthetrum brunneum species in different populations by using geometric morphometry method. For this purpose, intra-species wing variations of three different Orthetrum brunneum populations collected from Tunceli province to the east of Anatolia Diagonale and Yozgat province to the west of Anatolia Diagonale and Western Mediterranean Region were investigated. Statistical analysis (Tukey HSD) showed that a large number of biometric characteristics differed statistically among these taxa (P <0.05). According to Principal Component Analysis (PCA), 4 components with total variance Eigen value over 1 can be explained among these groups and samples of Tunceli population are separated from other populations by Discriminant Function Analysis (DFA). These findings support the idea that Anatolian Diagonale may be a barrier for populations of O. brunneum. Therefore, it is necessary to study and take into account the variational situations of Anatolian samples.
