Thermokarst as a short-term permafrost disturbance, Central Yakutia

Permafrost and Periglacial Processes, 2004
AbstractThe widespread occurrence of alas depressions in Central Yakutia is not necessarily evidence of modern thermokarst activity. Typically, a near‐surface ‘shielding layer’, formed as the result of deep thaw in exceptionally warm years, protects underlying icy sediment from thaw. In spite of current climatic warming, there is no noticeable increase

Segetal vegetation of Central Yakutia

Folia geobotanica & phytotaxonomica, 1988
Seven associations of segetal vegetation are distinguished for the vast arable lands of Central Yakutia. Low species richness and the prevalence of annual weeds are the main features of these communities. Only two dominant speciesSphallerocarpus gracilis andSaussurea amara represent Asian types of areals.

Microorganisms in forest soils of central Yakutia

Eurasian Soil Science, 2006
The population of saprotrophic, oligotrophic, and nitrogen-fixing microorganisms was determined in cryogenic forest soils of central Yakutia. The number of saprotrophic bacteria ranged between 108 and 1010 cell/g of soil. In the soils of Buryatia, this parameter (108) was 4 orders of magnitude as high as in the soils of European Russia (106). According

THERMOKARST AND ITS MANIFESTATIONS IN CENTRAL YAKUTIA

Естественные и технические науки, 2020
Территория Центральной Якутии это район распространения многолетнемерзлых горных пород, здесь повсеместно развит, такой мерзлотный геологический процесс как термокарст. В статье рассмотрен термокарст и его проявления, выражающиеся в формировании ярковыраженного полигонального микрорельефа и развития подземного (повторно-жильного) льда.

Cold adaptation in insects of Central Yakutia

Biophysics, 2007
The mode of cold hardening was for the first time assessed for 20 insect species living in the extremely cold climate of Yakutia. All insects tested were found to adapt through freeze tolerance, producing ice-nucleating agents that cause the hemolymph to freeze at high subzero temperatures.

Classification of ultracontinental boreal forests in central Yakutia

Folia Geobotanica, 2002
Using the Braun-Blanquet approach, five associations of boreal forests were distinguished in central Yakutia, the most continental part of eastern Siberia. Ecological features of the syntaxa were explained with the use of the DCA ordination of 50 releves.

Multifunctional machinery for soil cultivation in the Central Yakutia

Кормопроизводство, 2018
В статье приведены результаты полевых исследований по применению многофункционального почвообрабатывающего комплекса «Обь-4-3Т» для предпосевной обработки мерзлотных почв в условиях Центральной Якутии. По экспериментальным данным установлено, что суммарное водопотребление на единицу урожая при ресурсосберегающей технологии составляет 105,5 мм, при ...
