Evaluation of developmental stability and cytogenetic homeostasis in populations of Rana ridibunda Pall. in Ul'yanovsk region

The status of Rana ridibunda Pall. in populations subjected to anthropogenic influence of various intensity has been evaluated. The status of the specimens in populations was evaluated by morphological (developmental stability as the level of fluctuating asymmetry) and cytogenetic (micronucleus test) methods. Disturbed developmental stability and cytogenetic homeostasis which indicate the changed status of the organism have been observed in populations affected by anthropogenic factors.
