The Impact of the Anatolian Diagonal on Biodiversity in Turkey: A Geometric Morphometric Study on the Wing Morphology of Platycnemis dealbata (Insecta: Odonata)

Present research has shown that zoogeographic barriers can have a significant impact on biodiversity. Türkiye has numerous ecobiological barriers and there has been an increase in research on the impact of the Anatolian diagonal on biodiversity. The objective of this study is to examine the variations in wing morphology of Platycnemis dealbata (Selys and Hagen, 1850) in different populations separated by the Anatolian Diagonal. To achieve this objective, the intraspecies wing variation of three different P. dealbata populations collected from the provinces of Iğdır and Hatay in the east of the Anatolian diagonal and Mersin in the west were investigated using geometric morphometry method. The findings of this study support the idea that the Anatolian diagonal acts as a barrier for P. dealbata populations.
