Morhometric correlates of host specificity in Dactylogyrus species (Monogenea) parasites of European Cyprinid fish

Popis výsledku v původním jazyce

We test the hypothesis that living on larger fish may impose constrains, i.e. the need to develop large attachment organs, related to the necessity to remain attached on large gills. For this, we compiled data on body size and morphometric maesurements of attachment organs of 44 Dactylogyrus species from 19 cyprinid fishes. Nineteen dactylogyrid species were considered as specialists and 25 as generalists. The lack of phylogenetic information lead us to perform comparative analyses using raw values andindependant contrast obtained by random phylogenies. Our results show that rich parasite communities are formed by specialists and generalists, whereas poor communities are composed mainly of generalit parasites. Moreover, specialists are found on largerhosts, which may reflect a specialization on a predictable resource, as larger fish love longer and offer large gills for parasite colonization. Parasite specialization is shown to be linked with adaptation of attachment organs to their
