Specific Features of the Life Cycle of R. arvalis Nilss. at the Territory of East Ural Radioactive Trace

V. L. Vershinin
Pages: 677–682

Abstract

Data obtained on the reproductive features, life duration, specificity of morphogenesis and genetic structure, trophic links, some physiological indices, bioaccumulation of moor frog inhabiting the territory of East Ural radioactive trace are generalized. It is shown that the stability of R.arvalis population existing for a long time under the conditions of radionuclide contamination is sustained due to the selective survival probability of the individuals with high stability of morphpgenesis and inherent physiological features.
