Occurrence and morphological anomalies varietyof populations of marsh frog (Anura, Amphibia) of the Middle Volga

In the Middle Volga region in 4 lake frog populations are marked morphological abnormalities of 10 types of external structure: polydactyly, polimeliya, ectromelia, ectrodactyly, absence of eyelids, eyes, the aberrations of pigmentation of the iris. We assessed abnormalities diversity in phenotypic diversity parameters μ and h. 1.65 times-increase in diversity index of anomalies spectrum (μ ± Sμ) in high antropopress (2,50 ± 0,021) compared to the controls (1,49 ± 0,004) was found.
