Spatial Structure and Organization of the Bird Communities in the Altay and West-Siberian Plain

Yu. S. Ravkin, S. M. Tsybulin, L. G. Vartapetov, S. G. Livanov, K. V. Toropov, V. S. Zhukov, V. A. Yudkin
Pages: 877–884

Abstract >>
Classification of the bird population of the West-Siberian plain and the Altay is carried out; the structure of the spatial variability of ornithocomplexes is revealed. With the help of qualitative linear approximation (a qualitative analogue of the regression model), the informative content of the obtained classification and structural representations is calculated.

Effect of Fires on Carbon Emission in the Pine Forests of Middle Siberia

G. A. Ivanova, V. A. Ivanov, E. A. Kukavskaya, S. G. Konrad, D. D. Makrey
Pages: 885–895

Abstract >>
Fires in the pine forests of Middle Siberia make a substantial contribution into carbon resources. The emission value is essentially affected by the intensity of forest fires, types of vegetation, and the conditions existing at the grow sites. During extremal fire-risk seasons, emissions from forest fires can increase several times. The duration of an average interval between fires decreases from the north to the south and is determined by the latitude and by the degree of landscape apartness, as well as by the anthropogenic load.

Latitudinal and Longitudinal Variations in the Ratio of Life Forms of Vascular Plants in the Coenofloras of Yamal and Taymyr

M. Yu. Telyatnikov
Pages: 897–912

Abstract >>
The comparison between the coenofloras of Yamal and Taymyr for three subzones is carried out: southern, typical and Arctic tundras. The parameters of activity and richness of species of the life-forms in coenofloras were used. The an

Pollution of Plant Organisms with Pathogenic and Opportunistic Pathogenic Bacteria

Yu. A. Markova, A. S. Romanenko, O. N. Tabarova, A. V. Dukhanina*
Pages: 927–931

Abstract >>
Bacteria of Enterobacteriaceae family were isolated from the soil, tissues and surface of a number of wild and cultivated plants. All the isolated cultures exhibited a wide range of stability against 11 antibiotics and high adhesiveness to human erythrocytes. Investigation showed the possibility of concentrating the microorganisms that are pathogenic for humans in plant tissues.

Ecological Features of Blooming and Bearing of the Siberian Species of Myricaria Desv. Genus

E. M. Lyakh
Pages: 945–949

Abstract >>
Results of the investigation of the siberian species of Myricaria Desv. genus are reported. Myricaria is a shrub the biology and ecology of which are still poorly investigated. It grows on pebble and rocky banks of the mountainous rivers in the southern regions of Siberia. The ecological features of blooming, bearing, ri

Weed Plant Associations in Leached Chernozems of Areas Near the Ob River

V. E. Sineshchekov, A. G. Krasnoperov, E. M. Krasnoperova
Pages: 981–986

Abstract >>
As a result of 17-year investigations, eight associations of weed vegetation in cereal-fallow rotation and unchangeable wheat in leached chernozems of the areas near the Ob River were singled out. Three of them are analyzed in the paper. The main effect on the formation of the weed community association was caused by long-term permanent agrocenosis factor.

Diploid Parthenogenesis Induction in Fragaria vesca L.

S. O. Baturin
Pages: 987–991

Abstract >>
The paper presents the results of unreduced egg-cell parthenogenetic development induction by intergeneric pollination in different ecotypes of  Fragaria vesca L. (2n = 2x = 14). Parthenogenetic seedlings had the same chromosome number as the mother plant did. We revealed various levels of tendency to pseudogamic diploid parthenogenesis among the specimens of F. vesca. Wild specimens less tend to the phenomenon of parthenogenesis than cultural ones (Alexandria variety) do. For F. vesca under the climatic conditions of West Siberia, diploid parthenogenesis is the facultative additive insuring mechanism of seed-forming which is realized in case of problems with pollination or fertilization.
