Abstract
The study aimed to characterize the species composition and compare helminth populations and communities in samples of helminths collected from marsh frogs in 3 localities in the city of Kyiv. Twenty helminth species were recorded in total, of which 8 were found in all 3 localities: the nematodes Cosmocerca ornata and Icosiella neglecta, and the trematodes Diplodiscus subclavatus, Haematoloechus asper, Opisthioglyphe ranae, Pleurogenes claviger, Pleurogenoides medians and Prosotocus confusus. In helminth infracommunities, species richness and abundance were the highest in frogs from Olzhyn Island (median 7 and 98, respectively). Helminth species richness was the lowest in the infracommunities from Lake Tiahle (median 4), while the abundance was the lowest in the infracommunities from Lake Telbin (median 51.5). From 3 to 4 species predominated in separate helminth component communities based on their high prevalence and abundance in the studied samples: D. subclavatus, I. neglecta, P. medians and P. confusus in Lake Telbin; Codonocephalus urniger, I. neglecta, O. ranae and P. confusus in Lake Tiahle; C. urniger, O. ranae and Tylodelphys excavata in Olzhyn Island. According to our observations, intense urbanization of Lake Telbin affects rather the abundance than the species richness in helminth communities of the marsh frog. On the other hand, the relatively low abundance of helminths in the infrapopulations from Lake Telbin resulted in comparatively higher diversity indices for the helminth component community in this locality. Moderate urbanization, on the contrary, results in the strong predominance of some helminth species and low values of the diversity indices.
