Abstract
Investigation revealed 21 kinds of pathologies in the embryonal development of amphibia and more than 30 kinds in small mammals at the territories with radiation-chemical environmental pollution. Differences in embryonal mortality and pathologies of embryogenesis were demonstrated both for the representatives of amphibia and mammals and within one class at the regions with different technogenic load. Embryonаl death and pathologies of embryonal development are considered as important reasons of reproductive losses for different species.
