Diversity, phylogeny, and phylogeography of Dactylogyrus (Monogenea) in the MiddleEast: what to expect from?

Popis výsledku v původním jazyce

In recent years, numerous studies have focused on exploring the diversity and phylogeny of Dactylogyrus (Monogenea) parasites found in cyprinoid fish within the peri-Mediterranean region. Despite the Middle East being recognized as a crucial crossroad in the historical dispersion of cyprinoid fish into the peri-Mediterranean, the diversity and phylogeny of their host-specific Dactylogyrus species in this region have been overlooked. The objective of the present study was to investigate the diversity, phylogeny, and host specificity of Dactylogyrus in the Middle East, aiming to reveal cyprinoid fish's historical dispersion through their Dactylogyrus species' phylogenetic relationships. Through extensive field data collection conducted in Iran, Iraq, and Turkey between 2018 and 2023, we examined the gills of 89 cyprinoid species for the presence of Dactylogyrus species. Seventy-two Dactylogyrus species were identified and used for the diversity analysis and phylogenetic reconstruction. Dactylogyrus vistulae, with 24 host species, has the widest host range in the Middle East. On the hosts, Squalius spp. harbored most Dactylogyrus species. For phylogenetic reconstruction, we used partial 18S rDNA, 28S rDNA, and the complete ITS1 region. Phylogenetic analyses, incorporating DNA sequences of Dactylogyrus obtained from GenBank and species collected from the Middle East, revealed the presence of seven major clades. Middle Eastern species were categorized into four clades alongside European, North African, and East Asian species, thus confirming the significant role of the Middle East in the diversification of Dactylogyrus and providing additional insights into the historical dispersion of cyprinoid fish. During this investigation, we uncovered 16 potentially new Dactylogyrus species for science originating from the Middle East. Surprisingly, several Dactylogyrus species (e.g., D. vistulae, D. goktschaicus, D. linstwoi) exhibited high genetic intraspecific variabilities. The genetic intraspecific variability associated with geographical distribution and host phylogeny, highlighted the underexplored diversity of Dactylogyrus in the Middle East.
