Biological productivity of bogs in West Siberia. // Tomsk State Pedagogical University Bulletin. 2008. Issue 4 (78). P. 53-57

New results of investigation of biological productivity of bog in West Siberia are presented. Production of bog ecosystem ranged from 150 to 600 g/m2 year and be conditioned of plan

PHYTOMASS, PRODUCTION AND DECOMPOSITION OF PLANT MATTER IN OLIGOTROPHIC BOGS OF THE MIDDLE TAIGA WESTERN SIBERIA // Tomsk State Pedagogical University Bulletin. 2009. Issue 3 (81). P. 63-69

Are given new experimental data on biological productivity and decomposition of plant matter in communities of oligotrophic bogs of the middle taiga. Are adduced quantitative assessments of phytomass, mortmass, production and decay rate of main peat plant species. The plants are divided on five groups by decay rate. It is found the dependence of the decay rate of plant matter and net primary production. It is shown that in the ecosystems of oligotrophic bog with increasing of the production, increases the rate of decomposition.

PRODUCTIVITY OF FEN IN GORNO-ALTAI // Tomsk State Pedagogical University Bulletin. 2010. Issue 3 (93). P. 87-91

A quantitative estimation of components of biological cycle is given. Identified reserves of phytomasse mortmass and net primary production of mountain fen Gorno-Altai in the Eshtykеl. Revealed the strong influence of permafrost on biological processes mountain fen. Stock vegetable substances either fen Altai close to stocks Tundra bogs. Reserve live phytomass is 4143 g/m2, and net primary production - 1285±142 g/m2 per year.

DECOMPOSITION DYNAMICS OF PLANTS OF BOGS (DATA: VASYUGAN BOG) // Tomsk State Pedagogical University Bulletin. 2012. Issue 7 (122). P. 87-93

The article describes decay dynamics of dominant plant species in bog complexes of the south taiga subzone in West Siberia. On bog plant material decomposition has taken place during warm time of year when water table was low and oxygen passed easily in upper part of peat. Plant fractions are divided into two types in accordance of the character decay. Plant fractions are grouped in three groups relatively of rate decay. The maximum decay rate belongs to Menyanthes trifoliate L., the leaves and rhizomes losses are 80 % mass relatively initial value after two years of experiments. The roots and rhizomes of Eriophorum vaginatum L. decomposed slowly then other fractions; the losses were 20 % after two years of experiments. Sphagnum mosses were lost from 20 to 40 % of mass.
