Název v původním jazyce

Genetic diversity and parasitism in the hybrid zone of two cyprinid species: common and mediterranean barbels (genus Barbus) in France

Popis výsledku v původním jazyce

Sampling of both sympatric and allopatric barbel populations was performed in 2007-2012. Using 30 microsatellite markers, low level of admixture between B. barbus and B. meridionalis was detected revealing 17 hybrid individuals in four barbel populations. Values of genetic diversity based on nine polymorphic microsatellites found in B. meridionalis populations were lower compared with populations of B. barbus. However, no significant differences in genetic diversity were found nearly between all pairs of populations. Our fish examination for the presence of metazoan parasites revealed that Monogenea represent the most abundant group of parasites in all studied populations, except for three populations. Significant trend towards higher abundance of Monogenea parasites in B. barbus compared to B. meridionalis was detected. However, no relationship between the level of genetic variability in Barbus populations and abundance of these parasites was found.
