Diversity, phylogeny, and phylogeography of Dactylogyrus (Monogenea) in the Middle East

Original language description

In recent years, several studies focusing on the diversity and phylogeny of Dactylogyrus (Monogenea) parasitizing cyprinoid fish were conducted in the peri-Mediterranean. The Middle East is considered as the important crossroad in the historical dispersion of cyprinoid fish into the peri-Mediterranean, however, the diversity and phylogeny of their host-specific Dactylogyrus species in the Middle East have been neglected. Hence, we aimed to investigate the diversity, phylogeny and host specificity of Dactylogyrus in the Middle East to explore cyprinoid historical dispersion through phylogenetic relationships of their Dactylogyrus species. In an extensive field data collection in Iran, Iraq and Turkey (2018-2022), the gills of 67 cyprinoid species were investigated for the presence of Dactylogyrus species. Seventy Dactylogyrus species were identified, their diversity and phylogeny were studied, for phylogenetic reconstruction partial 18S rDNA, 28S rDNA, and complete ITS1 region were used. Using DNA sequences of Dactylogyrus retrieved from GenBank and those of the Dactylogyrus collected from Middle East, phylogenetic analyses revealed seven major clades. The Middle Eastern species were positioned in four clades with European, North African, and East Asian species, confirming the role of the Middle East in Dactylogyrus diversification and shedding more light on cyprinoid historical dispersion. From the Middle East, seven potentially new Dactylogyrus species for science were revealed. Unexpectedly, high genetic intraspecific variabilities were documented in several Dactylogyrus species (D. lenkorani, D. goktschaicus, and D. linstowi). The genetic intraspecific variability associated with geographical distribution and the host phylogeny indicated the underexplored diversity of Dactylogyrus in the Middle East. This study was supported Czech Science Foundation, project no. GA20-13539S.
