This volume contains a comprehensive synthesis of mire rearch concerning the palaeoecology and palaeogeography of Eastern Fennoscandia, i.e. Karelian republic and Murmansk region (Kola Peninsula), done during the last 60 years in the Karelian Research Centre of the Russian Academy of Sciences in Petrozavodsk. The main aim of publishing the book in English was to bring the knowledge, previously available mainly in Russian only, to the international specialist and scientific community in Nordic countries, in Central Europe, in North America and also elsewhere.
