THE SOIL AS A SUBSTRATUM FOR DEVELOPMENT OF ASCARIS LUMBRICOIDES L., 1758 ^{[№ 12 ' 2008]}
In the Bashkir Trans-Urals, the ascarid eggs development on the surface in the steppe zone during spring and summer period is more 15-25 days; during autumn and winter period more 90-110; in the forest-and-steppe zone is more 20-40 and 110-130; in the mountain-and-forest zone is more 25-50 and 125-150; at the depth of 20 cm is more 25-40 and 100-120; 30-50 and 130-140; 35-60 and 140-170 days accordingly. The conditions for the ascarid eggs development on the surface in the steppe zone are formed since the 2-nd decade of April until the 1-nd decade of October; in the forest-and-steppe zone – since the 3-d decade of April until the 3-d decade of September; in the mountain-and-forest zone – since 1-nd decade of May until the 2-nd decade of September.

HELMINTHOFAUNA OF THE AMPHIBIAN SPECIES IN THE BASHKIR TRANS-URALS ^{[№ 12 ' 2008]}
It was found that 3 amphibian species (R. arvalis, R. temporaria, B. viridis) from Uchalinsky District, Bashkortostan, have 6 species of helminthes pertaining to the Class Cestoda – 1 species, Trematoda – 3 species, Nematoda – 2 species. The composition of helminthes directly depends on the host lifestyles: the semiaquatic groups have more diverse parasitofauna compared with the terrestrial groups.
