Floristic composition of Holocene peat bogs in the Pur-Taz interfluve in the north of Western Siberia |
|
|
The species distribution of plants, phytocenoses, and biotopes in the peatlands of the southern tundra is necessary for the reconstruction of natural landscapes and ecological conditions in the Holocene. Changes in the floristic composition, degree of decomposition, ash content, and radiocarbon age of peat have been determined in the peat bogs of the Tazovsky district of the Yamal-Nenets Autonomous Okrug. It has been established that the diversity of vegetation during the period of peat formation depended both on global climatic fluctuations in the Holocene and on local environmental conditions that determine the type of plant nutrition in khasyreys - their hypsometric position, watering and dryness.
