Some aspects of the production formation and efficiency of the energy use in aquatic ecosystems are discussed. The ecosystem production is defined as the difference between the gross total primary production and total expenditures on metabolic processes by all organisms in the ecosystem. The equations of the dependence of the ecosystem production on the average depth of a waterbody and the share of the primary production of phytoplankton in the total production are derived. The average value of the coefficient of the ecosystem efficiency in some waterbodies (53%) indicates that aquatic ecosystems use efficiently energy. The efficiency of the energy use increases with the increase of the biomass turnover rate. High production in the ecosystem can be obtained in case of its structure simplification.

Keywords: ecosystem, production, efficiency of energy use, phytoplankton, macrophytes, periphyton.

The long-term dynamics of suspended matter in the Naroch lakes has been analyzed with the help of Autoregressive integrated moving average (ARIMA) models. Comparison of the models showed that apart from seasonal fluctuations all Naroch lakes were affected by dramatic impact, which resulted in a rapid decrease of absolute values and fluctuations decrease of seston concentration. The models indicate that, in contrast to the lakes Naroch and Myastro, dynamics of the seston concentration in Lake Batorino is characterized by longer period of stabilization after the impact which occurred in 1991.

Keywords: suspended matter (seston), long-term dynamics, ARIMA model, trend, intervention, eutrophication, benthification, phytoplankton, chlorophyll.

Content of the Total Free Nucleotides in Plankton in the Rybinsk Reservoirs (Upper Volga).

Institute for Biology of Inland Waters RAS, 152742 Borok, Russia

e-mail: mineeva@ibiw.yaroslavl.ru

Determination of the total free nucleotides (TFN) in plankton as a whole and its size fractions was carried out in 2006 at the Rybinsk Reservoir using the author's modification of the spectrophotometric method. TFN content that made 58.1 ± 5.4, 75.2 ± 4.6 and 64.1 ± 7.3 g/l during spring, summer, and autumn, respectively, is closely correlated to the total plankton biomass (r = 0.67), and the TFN/CHL ratio correlates with the ratio of heterotrophic biomass and autotrophic biomass (r = 0.96). The share of size fraction >3 m (microplankton and nanoplankton) in nucleotides stock makes 77 ± 4%, 74 ± 3%, and 47 ± 3% in spring, summer, and autumn, while the fraction with the size of 0.45–3 m (ultraplankton) makes 23 ± 4%, 26 ± 3%, and 53 ± 3% respectively. To estimate plankton biomass using TFN content, the regression equations were obtained.

Keywords: total free nucleotides (TFN), plankton, size fractions, Rybinsk reservoir.

The specific flora of temporary plant groupings in lakes coastal areas of lakes during periodic shallowing has been investigated. The structure of ecological groups in respect to humidification, life forms, phytocoenotic groups has been analyzed as the aggregate of various plant life strategies at sharp changes of environmental conditions. The dependence of spatial distribution species and long-term dynamics of the floristic complex on the soil type has been found.

Keywords: flora, taxonomic structure, ecological groups relative to the humidification, life forms, phytocoenotic groups, shallowing band, piedmont lake, Southern Urals.

Effect of Triiodothyronine on the Activity and Sensitivity of Glycosidase to Heavy Metals (Cu, Zn, Pb) in Juvenile Blue Bream Ballerus ballerus (L.).

Institute for Biology of Inland Waters, RAS, 152742 Borok, Russia

e-mail: golovanova5353@mail.ru

The influence of exogenous triiodothyronine (0.25 ng/ml) on the activity and sensitivity of glycosidase (maltase, amylolytic activity) to ions Cu, Zn and Pb (25 mg/l) was studied in the whole organism of juveniles of the blue bream Ballerus ballerus L. We found that treatment of fishes with triiodothyronine resulted in an increase of the amylolytic activity. On the contrary, maltase activity was not affected. The exposure to exogenous triiodothyronine also resulted in the decrease of the sensitivity of glycosidase to the in vitro action of the ions of biogenic metals Cu and Zn, and in an increase of the sensitivity of the maltase to the action of Cu, Zn and Pb ions.

Keywords: Cyprinidae, blue bream, digestive glycosidase, triiodothyronine, heavy metals, Cu, Zn, Pb.

The Effect of Nickel Chloride on Seeds Germination and Morphophysiological Parameters of Seedlings of Alisma plantago-aquatica L. and Sium latifolium L.

Institute for Biology of Inland Waters RAS, 152742 Borok, Russia

e-mail: lapir@ibiw. yaroslavl.ru

The effect of nickel chloride concentrations in the range from 1 to 1000 mg/l on seed germination development of organs and pigment system in seedlings of Alisma plantago-aquatica L. helophyte and Sium latifolium L. hygrohelophyte was studied. It is shown that nickel chloride has practically no effect on the germination of Alisma plantago-aquatica L., however it suppresses the germination of Sium latifolium L. It is demonstrated that the toxicant supressed the growth of seedlings and synthesis of photosynthetic pigments. The length of cotyledons and hypocotyl is less variable, with much stronger effect on roots and leaves. It is determined that the morphometric parameters are less sensitive to the toxicant, compared to physiological ones. In general Alisma plantago-aquatica L. is more resistant to the effect of nickel chloride than Sium latifolium.

Keywords: nickel chloride, Alisma plantago-aquatica, Sium latifolium, seed germination, seedlings development, chlorophyll, carotenoids.

The heavy metals content in oligochaetes of two small rivers flowing through the central part of a large industrial city was researched. It was established that the concentration of mobile (available for plants) forms of metals in the oligochaеtеs was higher than the concentration in the sediments. A similarity pattern between the accumulation of pollutants in the bodies of oligochaetes and the concentration of heavy metals in the river sediment organic matter was discovered in both urban watercourses.

Keywords: macrozoobenthos, oligochaetes, small rivers, urban areas, heavy metals.
