Comparative analysis of the parasitocenoses of amphibians from the family Ranidae (Anura) in the urbanization gradient

详细

The parasitofauna of frogs from the fam. Ranidae (R. arvalis, R. temporaria, and P. ridibundus) has been studied in the urbanization gradient. A total of 22 parasitic species belonging to the following four taxonomic groups have been found: Protozoa, Trematoda, Monogenoidea, and Nematoda. The transformation of parasitocenoses with the growth of urbanization along with the preservation of specifics typical for the adaptive subzone in each amphibian species is accompanied with their depletion as well as with an increase in the proportion of trematodes, which results in a decrease in the system stability and increases the probability of parasitic pollution of the environment.
