P.R. Makarevich and D.G. Ishkulov (MMBI) consider the impact of regional climatic factors on the intra-, inter-annual and long-term variability of zooplankton communities, marine fish and benthos in the Barents Sea. The seasonal development of phytoplankton in waters of Franz Victoria trough and adjoining water areas of the Franz Josef Land archipelago is described in the article by A.A. Oleynik (MMBI). A team of specialists from the MMBI (E.A. Frolova, O.S. Lyubina et al.) conducted the study of benthic communities near coasts of the Spitsbergen, the Franz Josef Land and the Novaya Zemlya and submitted a large body of the initial data.
Two articles by S.E. Belikov (the Research Institute for Environmental Protection, Moscow region), the recognized leader in research of Arctic mammals, are devoted to results of the study of changes in population and habitat of polar bears and marine mammals of the Russian Arctic under the impact of anthropogenic and natural factors. The all year round population nonitoring accomplished by expedition groups onboard atomic icebreakers on the Northern Sea Route has become an important methodical innovation in the Arctic fauna researches. Methods and results of the polare bear researches performed in the MMBI expeditions are represented in the paper of G.G. Matishov, A.A. Kondakov and N.N. Kavtsevich.
L.A. Kolpashchikov (the Extreme North Agricultural Research Institute, Noril’sk) has been studying the unique world’s largest Taimyr population of the wild reindeer on the Taimyr Peninsula during almost 40 years. In the joint article with V.V. Mikhaylov (Institute of Automatics and Informatization, St-Petersburg) he describes the current population state, its spatial distribution, peculiarities of the population dynamics and migration, which have significantly changed over the past decade in connection with the increased economic activity on the peninsula and climate changes.
It is known that one of the longest series of long-term study of population dynamics of the Norwegian lemming is available in the Lapland reserve on the Kola Peninsula. Its scientific employee G.E. Kataev has continued the research of the population dynamics of Norwegian lemmings, started here by A.A. Nasimovich, G.A. Novikov, O.I. Semenov-Tian-Shansky, T.V. Koshkina etc. in 1930 and then compiled them. The article is of a great interest to predict the dynamics of this rodent species and to define trends in a changing climate.
