QUANTITATIVE CHARACTERISTICS OF SEASONAL ASPECTS OF THE BIRD POPULATION IN KEMEROVO CITY AND ITS VICINITIES

Authors: Klimova N. V., Toropov K. V.

On the basis of the data of year-round accounts in the city of Kemerovo and its vicinities in 1999 - 2001 a quantitative assessment of seasonal aspects of the bird population is given. Seasonal changes of the total number of birds, the specific diversity, the dominating species, the total biomass, the amount of the energy transformed by birds, their multistage distribution and faunistic composition are characterized and compared for all habitats surveyed.

GENETIC DIVERSITY IN POPULATIONS OF THE SILVER CRUCIAN CARP CARASSIUS AURATUS GIBELIO (CYPRINIDAE, CYPRINIFORMES) AS DEPENDS ON REPRODUCTION TYPE AND RESERVOIR SIZE

Authors: Zhigileva O. N., Kultysheva M. E., Svatov A. Y., Urupina M. V.

The paper presents data on the polymorphism of the interior simple sequence repeats of DNA in the silver crucian carp Carassius auratus gibelio from waterbodies in the Western Siberia. The proportion of the polymorphic ISSR-PCR bands in the silver crucian carp populations from different lakes varied from 40 to 70%, the rate of Nei’s gene diversity being 0.16 – 0.25. Genetic diversity indicators were lower in the populations primarily presented by females, as compared with bisexual ones.
