Аннотация

In this study, we analysed a 64 cm long sediment record from Lake Aunakit located on the Kropotkin Range (East Siberia, Russia) for subfossil diatoms and chironomids to provide an improved reconstruction of the environmental changes in the area for the past 4.2 ka. Diatom record is divided into four zones (0-0.84, 0.95-1.25, 1.3-2.0 and 2.0-4.2 ka BP). Duration of chironomid record is 1.8 ka, and this record is divided into five zones 1.8-1.5, 1.5-1.4, 1.4-1.25, 1.25-0.6, and 0.6-0 ka BP.
