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 Heavy metals in the objects of water ecosystems The influence of precipitation on the hydrochemical conditions of boundary water bodies The ecosystem of the river Shuya, the main tributary to Lake Onega 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 Karelian-Norwegian fish-breeding farm on the White Sea Ecologo-toxicological problems of heavy-metal pollution in fresh-water biocenosis in North-West Europe Salmon population monitoring in northern countries 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 Protected natural territories in Karelia Atlantic salmon (stock, reproduction, parasites) Ecosystems of the Friendship nature reserve Ecosystems of the Oulanka-Paanajarvi region Reindeer 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 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" 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 Introduction of new medicinal and forage plants in Karelia Effector functions of the organism immune system, in the process of adaptation to the habitat Ecosystem studies in the forests in the taiga zone Floristic studies in Karelia. Creation of a data base on "Flora in Karelia" Ecological safety of cities and districts of 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) Ecological requirements for technologies, equipment and forage used for aquaculture
