Production Hydrobiology: State and Development (for the 100 Year Anniversary of Georgii Georgievich Winberg)

A. F. ALIMOV

Abstract >>
The role of G. G. Winberg in the genesis and development of production hydrobiology, and the modern state of this scientific discipline which is the basis of the theory of functioning of aquatic ecosystems are characterized. It is noted that for further development a study of information flows and networks in ecosystems are necessary.

Evaluation of Possible Causes of Non-Predatory Mortality of Crustacean Zooplankton in a Small Siberian Reservoir

O. P. DUBOVSKAYA

Abstract >>
Non-predatory specific mortality (NPSM) of two dominant zooplankton species - Daphnia longispina (in one year Daphnia cucullata) and Cyclops vicinus was estimated in 1997-2000 sampling seasons with the help of a new direct method - live/dead sorting and sediment trap measurements. Simultaneously measured ecological factors such as water temperature, pH, dissolved oxygen, biomass of cyanobacteria, diatoms, green algae and euglen

Zooplankton and Sedimentation of Suspended Substances in Lakes

R. A. DERENGOVSKAYA , A. P. OSTAPENIA

Abstract >>
Results of long-term (1989-2003) studies of sedimentation processes and participation of zooplankton in them are shown on the example of two lakes of Belarus (Naroch and Sviatskoye). Despite the fact that the lakes studied differ considerably in a series of hydrological and production parameters, their values of sedimentation flows are surprisingly close - (1,11

"Top-Down" Biomanipulations in a Small Siberian Reservoir

M .I. GLADYSHEV, S. M. CHUPROV, V. I. KOLMAKOV, O. P. DUBOVSKAYA, E. S. KRAVCHUK, E. A. IVANOVA, M. Yu. TRUSOVA, N. N. SUSHCHIK, G. S. KALACHEVA, V. G. GUBANOV, I. G. PROKOPKIN, I. V. ZUYEV, O. N. MAKHUTOVA

Abstract >>
In a small water body where daphniae had been absent for two years, a "top-down" manipulation was carried out by means of introducing pike and removing the main planktophage - crucian. After the bio manipulation, water blooming by the cyanobacterium Microcystis in late summer ceased. The effect observed evidently was attained due to cessation of direct stimulation of blooming by planktophagous fishes, but not by the trophic cascade. At the same time, the water blooming by An

On the Possibility of Application of Hypophthalmichthys molitrix for Prevention of Water "Blooming" in Siberian Cooling Water Dodies

V. I. KOLMAKOV

Abstract >>
Analysis of literature dedicated to application of silver carp Hypophthalmichthys molitrix (Valenciennes, 1844) for prevention of mass development of blue-green algae and experimental studies of the feeding spectrum of the silver carp was carried out. Conditions under which introduction of H. molitrix can result in a perceptible decrease of the blooming level are considered. Practical and theoretical recommendations on introduction of silver carp into warmed waters of Siberian cooling water bodies are made.

On Conceptions of Biochemical Ecology and Hydrobiology: Ecological Chemomediators

S. A. OSTROUMOV

Abstract >>
Earlier, the author published two books and some papers in which he described conceptual foundations of new scientific disciplines - biochemical ecology and biochemical hydrobiology. These trends in research include studies of the role of chemical substances in interorganismal interactions, in communication and regulation of supraorganismal systems. Another part of biochemical ecology concerns studies of the destiny and transformation of chemical substances that are external with respect to the organism, when they in

Role of Macrophages in the Variability of Zooplankton Community Structure in the Litoral Zone of Shallow Lakes

V. P. SEMENCHENKO

Abstract >>
Distribution, daily variability and zooplankton aggregation in the litoral zone of lakes, and the influence of various macrophyte species on its community structure were considered. It is demonstrated that both direct and reverse horizontal migrations of zooplankton are caused mainly by the pressure of fishes. The influence of predatory zooplankton is of smaller importance and is directed mainly onto small-size species. The expression of horizontal migrations of zooplankton decreases with the depth, and the effect of "shore avoidance" is observed in large-sized zooplankton species and is caused not only by fishes pressure, but also by other, most probably abiotic, factors. The problem of interaction between macrophytes and zooplankton cannot be reduced only to the role of macrophytes as a refuge. Unclear remain the allelopathic properties of macrophytes, the competitive relations between separate zooplankton species in macrophyte thickets, and the influence of predatory invertebrates associated with macrophytes. Obscure is also the role of macrophytes as a factor changing hydrodynamic processes in the littoral zone of lakes.

On Topical Reationships and Consortive Associations in Communities

A. A. PROTASOV

Abstract >>
A system of biocenotic associations in communities and the conception of consortium are considered. Distinction of cenotic consortium in addition to the individual one is proposed. Questions of application of the conception of cenotic consortium to the study of the structure of communities in connection with their localization in the biocenotic gradient are considered.

The Role of Litoral of Reservoir in the Initiation of Water "Blooming" by Blue-Green Algae

E. A. IVANOVA

Abstract >>
On the example of upper Yenisei shallow and deep reservoirs, the influence of the shallow-water zone on the initiation of water "blooming" by blue-green algae is considered. It is demonstrated that deep-water canion reservoirs with poorly developed littoral zone are nor affected by water "blooming", or it happens only in shallow parts of the reservoirs.
