Abstract

V originále

Four Ponto–Caspian goby fish are regarded as invasive because of their ability to establish abundant populations in non–native areas. Native populations of all species collected from Bulgarian section of the Danube River, non-native populations of N. kessleri and N. melanostomus from Austrian section of the Danube River and non-native populations of N. fluviatilis and N. gymnotrachelus from Vistula River, Poland, were examined for parasite infection and 15 polymorphic microsatellite loci. The low level of polymorphism of microsatellite loci was observed in the introduced populations of N. fluviatilis and N. gymnotrachelus comparing to the native populations, which could be explained as the consequences of invasive strategy and founder effect. The gene diversity was similar in native and introduced populations of N. kessleri and N. melanostomus. Parasitological examination revealed that introduced N. fluviatilis and N. gymnotrachelus had lower parasite diversity and species richness than native fish, whilst similar structure of parasite community was found in native and introduced N. kessleri and N. melanostomus. The similarity in parasite communities and microsatellites suggests the different way of distribution for N. fluviatilis and N. gymnotrachelus versus N. kessleri and N. melanostomus. The work was supported by projects No. MSM0021622416 and LC522.
