Studying the active layer of oligotrophic bogs in the Taiga zone of Western Siberia
In this paper, we identify and describe the active and inert horizons of oligotrophic bogs. These often appear to be a fire risk to oil and gas extraction industries, but these bogs are a complex biological system also. We describe three structural layers for the active horizon.

| Summary: | In this paper, we identify and describe the active and inert horizons of oligotrophic bogs. These often appear to be a fire risk to oil and gas extraction industries, but these bogs are a complex biological system also. We describe three structural layers for the active horizon. These are the turf layer, the porous layer, the intermediate layer. We have investigated the morphological characteristics of these layers. For each layer, we gave the measurement of physical parameters – pH, general mineralisation, conductivity, coefficient of ash and moisture. In each selected layer we study microbiological parameters – microbial biomass, the carbon of microbial biomass, basal respiration and microbial metabolic quotient. Microbiological studies have established the boundary between the aerobic and anaerobic conditions in active layer of oligotrophic bogs. In each layer, we have established the biochemical characteristics of layers studying enzymes catalase and invertase. The obtained data make it possible to assess the functional processes in the active horizon of the wetland’s ecosystem. |
