Work in Progress in the fields of Biology and Ecology: Finnish and Russian Karelia. Its environment Assessment of the immune status of an organism under the effect of a pollutant of a pulp and-paper plant Ecomonitoring of the World's Great Lakes: Onega, Ladoga Ecological safety in the regions of Karelia near the Finnish border Biological productivity of lakes of various trophic status The ecosystem of the river Shuya, the main tributary to Lake Onega The effect of some chemical components (selenium, iodine etc.) on fish populations Probems of the Ecology of the White Sea Adaptation of the "Baltic Environment" project within the International Programme called "The Baltic University" for Petrozavodsk University Biogeochemical studies of trace elements in natural products in Karelia Development of the system of Continued Environmental Education in Karelia Protection of Climate and Energy Saving Ecology of the White Sea Ecological education History of nature use by different ethnical groups of Karelia Dendrochronological study of the dynamics of nature processes Perception properties of selga landscapes in Karelia Ecological education at the primary school level Ecological education for teachers Water dynamics and thermal regime in lakes of different types Large Lakes: Onego, Ladoga  Biodiversity of terrestrial and aquatic ecosystems in eastern Fennoscandia (within the biosphere reserve "Northern Karelia") Parasites of salmonidae Ecosystems of the Friendship nature reserve Inventory and monitoring of terrestrial ecosystems of flora and fauna in the reserve "Kostomukshsky" Ecosystems of the Oulanka-Paanajarvi region Seasonal migrations of large mammals between the Republic of Karelia and Finland Ecological bases for the management of elk populations in the adjoining Karelian and Finnish territories Dynamics of game number in eastern Fennoscandia Structure and vegetation of marsh ecosystems in eastern Fennoscandia and their protection Assessment of condition of lake and river ecosystems in Finland and nothern European Russia Optimizing physiological state of animals under northern conditions Function of pine forests and effect of industrial discharges on growth and development of pine stands Organizing the catchment area for integral monitoring of north taiga ecosystems in the territory of the reserve "Kostomukshsky" Forest entomological monitoring: structure of en tomofauna in the forests of different ages and conditions Carine- biotopes of Baltic states and the Republic of Karelia "The Ladoga ringed seal" Investigation of biology of long- and wide-clawed crayfish in reservoirs of Karelia Studies of the population structure of lake salmon and of salmon trout in the basins of the near-boundary rivers, the Pista and the Olansa Projects proposed to be implemented in cooperation with other universities:  Aquatic and terrestrial ecosystems of the North. Their use and protection The state of the lake-river systems of the North Ladoga basin perspectives for their use Biological resources and use of the lake-river systems of the White Sea basin Heavy metals in fish food-webs Introduction of new medicinal and forage plants in Karelia Effector functions of the organism immune system, in the process of adaptation to environment Ecosystem studies in the forests in the taiga zone Floristic studies in Karelia. Creation of a data base on "Florain Karelia" Peculiarities of the dynamics of the edible mytilus population in the White Sea Anthropogenic transformation of flora on urbanized Northern territories Bryoflora and lichenoflora in the territory of the Botanical Garden of PetrSU as a unique natural complex Genetic and phenetic peculiarities of insular populations of adder Transformation of zoocenosis on the island Kizhi due to a change in the vector of anthropogenic loads Symbiotic and unsybiotic nitrogen fixation Introduction of coniferous plants in Karelia Selection of new decorative trees and shrubs for landscaping in Karelian towns The Barents Sea bottom fauna data bank Population structure of deep-water prawn Pandalus borealis Kr. in the N-E Atlantic Seas Amphipoda (Crustacea) of the Arctic Seas North-European Seas (educational ecological course) Interaction of society and nature Monitoring of heavy metals in the territory of eastern Fennoskandia Territorial structures of brown bear population in the mid-taiga Global climatic change and dynamics of ecosystems Interaction of immune system cells in the lymphocytic differentiation processes Analysis and coordination of control of conditions, for small passerine bird population Development of a scheme for water supply for the settlements in Karelia using subsurface sources (Priazha region) Studies of the fauna of fish parasites and of lake ecosystem topology
