Diatoms of Holocene Sediments of Lake Bolshoy Kharbei (Bolshezemelskaya Tundra, Russia)
Arctic lakes, which are not affected by direct human impact, are excellent objects for paleoclimatic reconstructions. Diatoms can be a source of information about the changes that occurred in lakes. The recent Holocene sediments from deep glacial arctic Lake Bolshoy Kharbei of Bolshezemelskaya tundr...

Arctic lakes, which are not affected by direct human impact, are excellent objects for paleoclimatic reconstructions. Diatoms can be a source of information about the changes that occurred in lakes.

In total, 122 taxa of 2 classes, 5 orders, 18 families, 45 genus of cosmopolitan forms with a predominance of alkaliphilic benthic species of diatoms preferring a standing – flowing waters, indifferent to salinity and moderate temperature conditions were revealed.
