metadata.name: dc.description.abstract
metadata.value: We studied diatom assemblages of the proglacial arctic lake Bolshoy Kharbey
  (Bolshezemelskaya tundra, Russian Arctic) from a short sediments core covering
  last ca. 200 years. In total, 121 taxa from 2 classes, 5 orders, 18 families,
  and 50 genera were identified. The diatom flora included species with mainly
  cosmopolitan distribution. The assemblages were dominated by alkaliphilic
  benthic diatoms preferring standing — flowing waters, indifferent to salinity
  and moderate temperature conditions. The main changes in diatom assemblages
  took place at ca. 1870 and 1980. After 1870, which can be attributed to
  the end of the Little Ice Age, the species richness rose, especially of planktonic
  centric and small penate diatoms. This rise of diatom diversity took place most
  probably in response to climate warming, related to prolongation of the growing
  season and period of open water. A negative trend in the evenness of the
  diatom assemblages during the last decades can be seen as an early-warning
  signal indicating a decrease of stability of the lake ecosystem.
