Dynamics of Vegetation and Soil Cover of Pyrogenically Disturbed Areas of the Northern Taiga under Conditions of Thermokarst Development and Climate Warming
Vegetation and soils of the North Taiga zone were studied in natural and thermokarst-disturbed areas of Yana-Adycha interfluve (northeastern Yakutia). Soil research includes a description and physicochemical analysis of samples. The objects of study were selected taking into account the landscape di...
