Biological Productivity of Oligotrophic and Eutrophic Mires in the Southern Taiga of Western Siberia
The results of long-term (1999-2007) investigations of Phytomass (above and below-ground living biomass), dynamics of phytomass and mortmass and net primary productivity of oligotrophic and eutrophic mire in southern taiga in Western Siberia (Tomskaya oblast) are presented. The storages of phytomass...

| Summary: | The results of long-term (1999-2007) investigations of Phytomass (above and below-ground living biomass), dynamics of phytomass and mortmass and net primary productivity of oligotrophic and eutrophic mire in southern taiga in Western Siberia (Tomskaya oblast) are presented. The storages of phytomass on different biogeocenoses of oligotrophic bog have similar values. Reserves of phytomass of eutrophic peatland are 2 times higher in comparision to oligotrophic bogs. Net primary production of different oligotrophic biogeocenosis has close values. NPP at eutrophic peatland is 1.7 times higher in comparision to oligotrophic bogs. The major part of production is provided by mosses and plant roots. The qualitative composition of phytomass depends on vegetation of the studied phytocenosis. The dynamics of phytomass and NPP depends on precipitation, air temperature, and water table level. The correlation between phytomass of herbs, shrubs and mosses and NPP peatland ecosystem are revealed. |
