[The biological indication of the radiation load in forest communities of small mammals]. / Bioindikatsiia radiatsionnoi nagruzki v lesnykh soobshchestvakh melkikh mleokipitaiushchikh.

The content of cesium-137 in the organisms of different species of small mammals in forests of Bryansk Province five years later the Chernobyl accident varies to a great extent within some modal value n.10(-6)-n.10(-7) Cu/kg. Gamma-radiation is about 200 mcR/h. The revealed radiation level results in increased mortality during embryonal and postnatal periods, as during these periods a very intensive process of radiocesium accumulation in the animal organism takes place. Statistically valid differences of young and old animals ratio with the asymmetrical deviation towards old age groups have been found on the polluted territory at the end of summer season.

Warble flies (Hypodermatidae, Oestridae) of some wild animals from Mongolia and Tuva.

Three species of warble flies Pallasiomyia antilopum, Oestromyia leporina and Cephalopina titilator from four species of wild animals were found. Hitherto unknown larva of the first instar of Pallasiomyia antilopum (Pallas, 1771) collected from the saiga (Saiga tatarica L.) is described.
