title: Molecular diversity of some species belonging to the genus Daphnia O. F. Müller, 1785 (Crustacea: Cladocera) in Turkey.
abstract: Daphnia is a freshwater zooplankton species with controversial taxonomy due to its high morphological variation linked to environmental factors and inter-specific hybridization and polyploidy in some groups. The aim of the present study is to examine molecular diversity of some Daphnia species in Turkey and to establish DNA barcodes of Turkish Daphnia species. Sequence analysis was performed using 540 bp region of cytochrome oxidase subunit I gene of mitochondrial DNA. A total of 34 haplotypes have been identified for Turkey. Daphnia pulex complex was divided into two clades with 16.1% sequence divergence according to molecular taxonomy based on Kimura 2-parameter. The clade which was molecularly diverged from Daphnia pulex with 16.1% sequence divergence was found to show 99% similarity with Daphnia cf. pulicaria (sensu Alonso 1996) instead of Daphnia pulicaria Forbes, 1893. Furthermore, this study has contributed to Turkish zoogeography by demonstrating the distribution of Daphnia species in Turkey.
