Species richness of parasite assemblages in the Chinese slipper Perccottus glenii Dybowski, 1877 (Actinopterygii) in the host's native and non-native ranges.
Species richness of parasite communities in the Chinese sleeper Perсcottus glenii was studied in its natural habitats and regions where this host had been introduced. Species richness of parasite infracommunities in both the native and acquired parts of the host's range is sufficiently described by Gamma distribution except for the introduced populations with species-poor (≤ 2) infracommunities. The resampling method was applied to estimate the statistical significance of differences in coefficients of the power-law equation s = anb, where a is the expected species richness in the first host individual examined, and b is the rate of species accumulation in parasite component communities (s) related to the increase in the number of examined host individuals (n). The species richness of infra- and component parasite communities in the Chinese sleeper was found to be significantly higher in native than in introduced habitats. Nevertheless, the rates of species accumulation in component parasite communities did not differ between the native and non-native ranges in spite of the differences in the taxonomic composition of parasites.
