Project objectives

Studying of the biological diversity of the ╬b River basin and ╬b-Irtish interfluvial area aquatic ecosystems at genetic, species, population and ecosystem levels. The ecotoxicological estimation of water objects by methods of bioindication and biotesting on the basis of biochemical, cytogenetical, physiological and ecological characteristics of biological systems of various organisation levels.

Background and significance of objectives

The choice of scientific goals in studying of the Siberian aquatic ecosystem is determined by the necessity of solving the fundamental scientific problem on establishment of a relative role of different natural and anthropogenic factors of time and space under the formation of structure, functioning and succession of large river ecosystems.

Practically all types of water ecosystems, water flows of various size, small and large reservoirs, steppe and mountain lakes, bogs are presented in the Ob basin. The typisation on hydrophysical, hydrochemical and hydrobiological parameters of different types of lakes of the Upper Ob basin and Ob-Irtysh interfluvial area was made: Lake Teletskoye, Lake Gorkoye-Peresheechnoye, Lake Kulundinskoye, Lake Kuchuk and channels adjacent to them; the natural and anthropogenic factors determining water quality of ecologically different sites of large Ob river system with Aley and Barnaulka inflows have been characterised.

The research of spatial - temporal non-uniformity of taxonomic structure, phyto- and zooplankton development level, contents of chlorophyll "Ó" simultaneously with vertical profiling by means of hydrologic STD-12 and SBE 25-01 SEALOGGER CTD probes allowed us to support the hypothesis on a prevailing role of hydrodynamic and hydrothermal factors in limiting plankton communities development in Lake Teletskoye.

A determining role of morphometry, altitude arrangement of water body and intensity of external water exchange in the formation of composition and structure of phyto- and zooplankton, zoobenthos and high water plants was established in the Novosibirsk reservoir. To estimate the degree of alive organisms participation in self-purification processes of water body the coefficients of heavy metals accumulation in hydrobionts of Novosibirsk reservoir were determined. The coefficients of accumulation in zooplankton can be arranged in the following order: Hg > Co > Mn > Be > Cd > Pb > Zn > Ni > Cu > Ba > V > As.

For estimation of factors of the formation and functioning of aquatic ecosystems the estimation of acute and chronic toxicity with the use of Daphnia, luminous bacteria and genotoxicity using barley root tissue, various objects of the environment surface water of rivers, lakes and reservoirs; some pollutants (pesticides, surface-active substances) was made.

Cytogenetic research of the Upper Ob basin water bodies and streams allowed us to expand the species lists of benthic animals to establish some seasonal dynamics laws of benthos organisms number and biomass.

The project includes the investigations of the biological diversity of the ╬b River basin and ╬b-Irtish interfluvial area at various levels of biosystem organisation and ecological water objects state estimation (Fig. 1). It is proposed to investigate the following objects: river ecosystems of various types (Ob with inflows, Aley, Chulym, Tom, Inya), Lakes (Teletskoye, the lakes of Ob-Irtysh interfluvial area and Upper-Chulym), Novosibirsk reservoir and cooling-reservoirs of thermal power stations.

The institutes possess research stations on Lake Teletskoye, Novosibirsk reservoir and Lake Chany, low Ob (Karym-Kary) (Fig. 2).

Research plan: approaches and methods

The methodological basis is a system analysis. The methodical approaches include long-term observations, comparative analysis, experiments and modelling of processes. The use of standard field and laboratory hydrophysical, hydrochemical, hydrobiological, biochemical, cytogenetic, karyological, physiological and paleological methods is proposed. Analysis of the results obtained using standard and special mathematical methods application as well as geographical analysis.
