Host-specific monogeneans: ecology, evolution and host-parasite associations

Popis výsledku v původním jazyce

Highly diversified host taxa usually exhibit high parasite diversity. Speciation and diversification of parasites especially those exhibiting high host specificity is closely related to the history and ecology of their hosts. Monogenea (Platyhelminthes), mainly gill and fin ectoparasites, are often recognized as specific to a single host species, congeneric hosts, or monophyletic assemblage of hosts. These parasites often exhibit high species diversity at the level of host species (and even et the level of individual fish). Monogenean species show microhabitat specificity expressed by restricted positions on fish gills to facilitate the mating contacts. These specific positions are closely linked with morphological adaptation, i.e., sclerotized structures of haptor. Host-specific monogeneans may reflect the biogeographical history and/or contemporarily contacts of their fish hosts exhibiting disjunctive distribution. We focused on several systems of the gill monogeneans of Dactylogyridae and their freshwater fish hosts. Using case studies, the current knowledge on ecology and evolution of congeneric gill monogeneans will be presented, i.e., processes of speciation and diversification highlighting the role of duplication and host switch revealed by cophylogenetic studies in highly diversified congeneric monogeneans, evolution of host specificity, evolution of microhabitat specificity and evolution of morphological adaptation. The role of host-specific monogeneans to reveal the historical intercontinental and intracontinental contacts between freshwater fish exhibiting disjunctive distribution was highlighted.
