The effect of water extract from bentonite on embryonic and larval development of the green toad (bufoviridis) with different phenotypes

Ontogenesis is a complex process of morphophysiological transformations. Embryonic and postembryonic development continuously affected by both endogenous environmental factors, which lead to variability in morphometric parameters. The research was conducted the laboratory ecological embryology Federal State Budgetary Educational Institution Higher Education North Osetian University (Vladikavkaz). results showed that under influence bentonite extract, morphological parameters green toad larvae with brown phenotype are more variable than an olive control experimental groups. Thus, embryos stable had phenotype, natural circumstances clay extracts.
