- Abstract
The composition of helminths and infestation indices of two frog species of living in Western Siberia ( Rana arvalis ( n = 1082) and Rana amurensis ( n = 33)) have been studied. Nine helminth species, including four nematodes and five trematodes, have been found. The following species were dominant and infected both frog species: nematodes Rhabdias bufonis, Oswaldocruzia filiformis, and Cosmocerca ornata and trematodes Haplometra cylindracea. The moor frog also hosted Dolichosaccus rastellus, Opisthioglyphe ranae, Pharingostomum cordatum (larvae), Parastrigea robusta (larvae), and Neyraplectana schneideri. The moor frog was characterized by higher species richness and diversity of helminths than the Siberian tree frog. The overall rates of helminth infestation have been the same in the moor frog and the Siberian tree frog. The invasion extensity was 85-100%; the index of abundance was 5.2-27.5. Differences in infestation rates of certain species by helminths were due to the biological peculiarities of the frog species.
