Diatoms as biomarker in changes of the Lake Zapovednoye state (Evenkia, Russia)
AbstractAs part of a multidisciplinary study aimed at paleoclimatic reconstruction in March 2015 and June 2018 cores of bottom sediments of Lake Zapovednoye (Evenkia, Russia) were obtained. Analysis of samples of bottom sediments by the diatoms composition - one of the main biomarkers or proxy of changes in a state of the lake, showed that, in addition to short-term changes, long-term changes in the species composition of diatoms at least twice occurred. It may be associated with changes in water inflow and level of Lake Zapovednoye. It is most likely these events could occur due to climate change.
