Abstract
Bottom sediment records in Lake Oron accumulated in the recent two decades have been analyzed. Chironomid and palynological studies of 10-cm core samples of bottom sediments have been carried out. The effect of climate dynamics on the fauna of chironomid larvae in Lake Oron, as well as on its hydrological regime, the local and regional landscape, and vegetation has been identified. Swamping of the coastal zone of Lake Oron has been supposed to have an effect on the process of water acidification in the lake; this process was shown to have started about the 1940s.
