Holocene environmental change in Kamchatka: A synopsis

A major ecosystem driver was the Siberian dwarf pine Pinus pumila, which spread northward during the Holocene in response to increasing winter snow, and caused water chemistry changes on arrival in the catchments of our study lakes and a response in diatom and chironomid assemblages. We also detect short-term responses, especially in diatom assemblages, to water chemistry changes following volcanic ash deposits.
