Metazoan parasites of freshwater cyprinid fish (Leuciscus cephalus): testing biogeographical hypotheses of species diversity

Popis výsledku v původním jazyce

The diversity and similarity of parasite communities is a result of many determinants widely considered in parasite ecology. In this study, the metazoan parasite communities of 15 chub populations (Leuciscus cephalus) were sampled across a wide geographical range. Three hypotheses of biogeographical gradients in species diversity were tested: (1) latitudinal gradient, (2) a favourable centre versus local oasis model, and (3) decay of similarity with distance. We found that the localities in marginal zones of chub distribution showed lower parasite species richness and diversity. A latitudinal gradient, with increasing abundance of larvae of Diplostomum species, was observed. There was a general trend for a negative relationship between relative prevalence or abundance and the distance from the locality with maximum prevalence or abundance was found for the majority of parasite species. However, statistical support for a favourable centre model was found only for total abundance of Mono
