In this paper, we assess the environmental impact of urbanization in three freshwater biotopes, using levels fluctuating asymmetry (FA) 10 meristic morphological traits Marsh Frog (Pelophylax ridibundus (Pallas, 1771)). Two studied biotopes are located boundaries city Plovdiv (one central part, other a suburban residential area), and third is vicinity village Orizare. Our working hypothesis bas...

The article presents the results of a study peripheral blood erythrocytes dominant animal species in Turkestan region. relevance this work is due to construction nuclear power plant on territory Uzbekistan (Jizzakh region, Lake Tuzkan), since areas region fall under potential influence plants and biota objects require monitoring at ‘zero stage’ before plant. data obtained are great importance a...

The anomaly P is a widespread morphological anomaly, which occurs in some groups of amphibians, caused by the trematode parasite Strigea robusta (Digenea: Strigeidae). This has been previously recorded water frogs genus Pelophylax and toads genera Bufo Bufotes . includes symmetrical polydactyly cases as mild attenuated form complex syndrome, severe strong deformations hindlimbs forelimbs. 3-hos...

The aim. aim of the work was to study indicators spermatogenesis in lake frog, Pelophylax ridibundus (Pallas, 1771), zone influence emissions from Burshtyn Thermal Power Plant (TPP).
 Materials and methods. Urinal sperm testes samples were taken male frogs under conditions anthropogenic pollution (Burshtyn industrial area). Such parameters as concentration ejaculate, number live spermatozo...
