Authors: Romanova E. B., Solomaykin E. I., Bakiev A. G., Gorelov R. A.

The results of our comparative analysis of parameters of the leukocyte blood system of underyearlings and mature specimens of the common viper Vipera berus are presented. The material was the blood of 36 females and 26 males caught in the Middle Volga basin, and 13 underyearlings born in captivity from 4 females of this sample. V. b.

COMPARATIVE DATA ON THE LEUKOCYTIC BLOOD FORMULA OF VIPERA BERUS AND VIPERA RENARDI

Authors: Romanova E. B., Solomaykin E. I., Bakiyev A. G., Gorelov R. A.

The leukocytic formulae of the peripheral blood of Vipera berus (Linnaeus, 1758) from the Samara region (Samara City) and Vipera renardi (Christoph, 1861) from the Saratov region (Khvalynsk district) were studied. Some features of the leukocytic blood composition of the species studied were revealed, manifested by the predominance of a specific component in the immune reactions of Vipera berus, in comparison with Vipera renardi.

DISTRIBUTION AND STATUS OF ADDER (VIPERA (PELIAS) BERUS) POPULATIONS IN THE VLADIMIR REGION

Authors: Solovyov V. A., Scopin A. E., Solovyov A. N.

The adder is a usual, locally-numerous species, occurring sporadically in most parts of the Vladimir Region: everywhere in the Meshchersky Lowland and Prinerlinski District, sporadically on the Kovrovsko-Kasimovskoe Plateau, Klin-Dmitrov Ridge, in the Opole. The largest adder populations are in Yuryev-Polsky District. The adder occurrence in different habitats varies from 0.01 to 1.33 individuals per 1 km route. The maximum adder occurrence is in Kovrov (1.33 ind. / km) Vyaznikovsky (0.83 ind. / km) and Kameshkovski (0.44 ind. / km) Districts.
