In Central Yakutia (Siberia) livelihoods of local communities depend on alaas (thermokarst depression) landscapes and the lakes within. Development and dynamics of these alaas lakes are closely connected to climate change, permafrost thawing, catchment conditions, and land use. To reconstruct lake development throughout the Holocene we analyze sedi...

Diatom analysis is one of the methods of paleolimnological research, with the help of which it is possible to determine the state and development of aquatic ecosystems in the past and present. Assessment of the current state of reservoirs is of great importance in paleolimnology, it will allow to obtain results about temperature regime, mineralizat...

The review shows the definition of morphometric characteristics, water chemical parameters and diatom assemblages of lakes located in the Arctic zone of Yakutia, in catchments of Anabar, Olenek, Lena, Indigirka and Kolyma Rivers. Main amount of these lakes has small water areas and low depth. The lakes are ultra fresh and mainly with neutral pH, ch...

This paper provides information about diatomic flora of 42 lakes located in the basin of the Indigirka River. The research material was sampled from surface sediments of lakes of various origin. The field material was collected during expeditions (in 2004, 2006, 2011, and 2017) using standard methods and a set of field equipment. Obtained data can...
