Phytoplankton in the Littoral and Pelagial Zones in the Volga Reach of the Rybinsk Reservoir in Years With Different Temperature and Water Level Regimes.

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

e-mail: katya.sah@mail.ru

The features of the floristic composition and dynamics of biomass of phytoplankton in shallow and deep areas of the Volga reach in Rybinsk Reservoir have been studied during the years with different thermal and level regimes (2009–2011). The f loristic diversity and biomass of phytoplankton increased with the decrease in depth. The increase in water temperature at low water level stimulated phytoplankton vegetation in the pelagial zone, and the decrease in biomass in the littoral, while high diversity of algocenoses was recorded irrespective of a bitope. The contribution of filamentous algae and cyanoprokaryotes to the biomass increased in the shallow littoral, and in the open part of the reservoir the biomass of mixotrophic flagellates decreased. Their abundance as well as the the abundance of zignematales increased with a decreasing depth.

Keywords: phytoplankton, floristic and cenotic diversity, biomass, thermal and water level regimes, Rybinsk reservoir, shallow area.

Vertical distribution of phytoplankton (chlorophyll a, CHL) was investigated in August 2015 at 25 stations in Ivankovo, Uglich, and Rybinsk reservoirs (Upper Volga, Russia) using the submersible fluorometer Fluoroprob bbeMoldaenke. Three types of CHL vertical distribution were identified under homothermy. Gradual CHL decline in the water column at the upper part of reservoirs; a sharp decline at a certain depth in the majority of river sections; uniform distribution opposite the mouth of a small river (river Kashinka in Uglich Reservoir), as well as at the open lake-like sites of the Rybinsk reservoir under the wind mixing. Average CHL content in euphotic layer at the stations of the three groups made respectively 25.0 ± 6.3, 44.1 ± 4.0, and 20.8 ± 2.9 mg/L; CHL contribution to the PAR absorption made 47 ± 9% and 66 ± 4% and 38 ± 6%. Under thermal stratification the vertical distribution of CHL corresponds to the course of the temperature (r = 0.85).

Keywords: chlorophyll, vertical distribution, Upper Volga reservoirs.

Dynamics of Chlorophyll a Content in the Ob River and its Relationship with Abiotic Factors.

Institute for Water and Environmental Problems, Siberian Branch of the Russian Academy of Sciences, 656038 Barnaul, ul. Molodezhnaya, 1, Russia

e-mail: kotovschik@iwep.ru

Seasonal and interannual dynamics of phytoplankton content (by chlorophyll a), organic matter and nutrients, temperature and water transparency have been analyzed based on the results of weekly samplings from February to November, 2012–2015 in the Ob River. The period of intensive phytoplankton growth in average- and high-water years is 70–90 days due to the prolonged flooding. In dry years this period can be more than 110 days due to the June maximum. The chlorophyll a maximum is usually observed in July–August, and in September as well. Seasonal dynamics of chlorophyll a is closely related with the water temperature during the summer-autumn steady low water level, transparency during the flood and the autumn low water, BOD 5 during summer and with nitrate content in summer-autumn period. As for a long-time period, the average annual concentration of chlorophyll a is directly proportional to the annual average temperature of water. According to the annual average (5.7–11.1 mg/m 3 ) and maximum (19.2–35.0 mg/m 3 ) concentrations of chlorophyll a, the trophic status of the river at the given site corresponds to mesotrophic-eutrophic water, and water quality – to the second class, i.e. “clean water”.

Keywords: chlorophyll, seasonal and interannual dynamics, hydrochemical parameters, phases of hydrological cycle, Ob River.

Assessment of Categories of Macrophyte Rarity.

Institute for Evolutionary Ecology NAS Ukraine, 03143, Kiev, ul. Lebedeva, 37, Ukraine

e-mail: lesyazub2@gmail.com

According to the results of temporal and spatial analysis of the macrophyte flora in waterbodies within the city of Kiev (Ukraine), local protection criteria have been developed for 22 rare and protected species. These criteria differ greatly from the regional criteria due to significant transformation of the environment. Over the past 40–50 years, impoverishment of a rare component of the macrophyte flora in waterbodies of the city has been documented: two species disappeared from the urban flora, seven species are critically endangered taxa, five species are endangered, four species are vulnerable, at a high risk of extinction, and four species are taxa at a low risk of extinction.

Keywords: macrophytes, rare species, category of rarity, Ukraine.

Hydrochemical and hydrobiological characteristics of 13 sites in the Okhta river within the precincts of St. Petersburg area were investigated in 2010. The Water Pollution Index (WPI), calculated according to hydrochemical parameters, characterizes the river water quality as “very polluted” to “extremely polluted”. According to the Pantle–Buck–Sládeček Saprobity Index, obtained on the basis of characteristics of macrozoobenthos, polysaprobic and α-mesosaprobic zones can be distinguished in the watercourse. Species richness of river macrophytes is low (18 species). The Macrophyte Water Quality Index makes it possible to assess them in the range from “polluted” to “very polluted” water. Macrophyte trophic indices MTR, IBMR and TIM indicate high trophicity of the watercourse sites. The general tendency, based on the analysis of hydrochemical materials, data of macrozoobenthos and macrophytes, has similar trend, deterioration of water quality downstream. Macrophytes characteristics reflect changes in hydrochemical parameteres along the river course. А high correlation (r = –0.76) of the Macrophyte Water Quality Index with the WPI was found. The possibility of use the data on macrophytes of small rivers in assessment of water quality was demonstrated.

Keywords: small river, bioindication, quality assessment, ecological status, macrophytes, trophic indices.

Interannual Changes in Species Richness and Quantitative Characteristics of Macrozoobenthos in Floodplain Lakes of Khopersky Nature Reserve.

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

e-mail: prokina@mail.ru

Interannual changes in species diversity and quantitative characteristics of f loodplain lakes macrozobenthos in Khopersky Nature Reserve Reservewere investigated in order to determine the dependence of these parameters on the changes in the flood pulse and degree of vegetation. Species richness is maintained in each lake at a certain level in a number of years. The interannual changes in the characteristics of lakes, especially during the period of spring flood, determine changes in quantitative characteristics of macrozoobenthos. The degree of vegetation cover of macrophytes does not affect species richness and quantitative characteristics of macrozoobenthos, but determines its saprobiological structure. The period of spring flood in these lakes may have a threshold of 30 days, necessary for the development of the relatively abundant macrozoobenthos communities. For the lake, which has a permanent connection to the river through the natural canal, the period of spring flood is not a major factor in determining the level of quantitative development of macrozoobenthos. For the studied floodplain lakes the significance of drying or a sharp drop of the water level content as a trapping pointi – trigger mechanism for shallow lakes ecosystems changesis confirmed.

Keywords: floodplain lakes, macrozoobenthos, floodpulse, species richness, total number, total biomass, interannual changes.

e-mail: gu@ibiw.yaroslavl.ru

The prevalence of processes of the increase in abundance and changes in sex composition of prussian carp populations in waterbodies which differ dramatically in ecological properties and are located far from each other (Lake Sevan and Rybinsk Reservoir) evidences for global tendencies affecting whole climatic zones. The environmental temperature increase due to global warming may be such a factor. Therewith, high thermophilicity and thermal stability of Prussian carp as well as its low sensitivity to lack of oxygen are sure to provide certain advantages over many other fish species inhabiting the same waterbodies.

Keywords: global warming, prussian carp Carassius auratus gibelio, abundance, sex composition, temperature.

Proteinase Activity in the Intestine of the Ruff Gymnocephalus cernuus (L.) (Pisces) Depending on the Summary Length of Cestodes Proteocephalus cernuae (Gmelin) Parasitizing the Gut.

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

e-mail: izvekov@ibiw.yaroslavl.ru

It is shown that infection of ruff with cestodes P. cernuae affects the activity of its intestinal proteolytic enzymes. The influence of cestodes on the activity of intestinal proteinases depends on the summary length of the worms occupying the gut. Proteinase activity decreases at smaller total length of the worms and increases at larger total length with serine proteinases being mostly involved. The essential share of activity is presented with metalloproteinases that can indirectly evidence an important role of microbiota in digestion of ruff. The small share of cysteine proteinases both in uninfected and infected fish may indicate to some minor intestinal damages caused by the attachment structures of cestodes.

Keywords: fish, Cestoda, proteolytic enzymes, proteinase spectrum.

In vitro experiments have been conducted to estimate the effect of temperature on morphometric and physical properties of hemocytesin the Prussian carp Carassius gibelio by atomic-force microscopy. The results show that at a low temperature (5 °C) morphometric properties of erythrocytes change compared to room temperature (20 °C), a high temperature (40 °C) causes changes of the morphometric properties of polymorphonuclear leucocytes. The low temperature may reduce adhesion and elasticity of polymorphonuclear leukocytes, and erythrocytes in Carassius gibelio, whereas the high temperature of incubation results only in the reduction of adhesion of polymorphonuclear white blood cells.

Keywords: erythrocytes, leukocytes, adhesion, elasticity, temperature.

e-mail: Luneva100@yandex.ru

The specific/volumetric activity of radionuclides at the global background levels in surface waters, sediments and aquatic organisms in the area of the planned waterworks of the Baltic Nuclear Power Plant (NPP) in the Neman River has been determined. The presence of Sr 90 Cs 137 in water due to global processes of the formation of radioactivity of the environment and the content of 3 H are studied. It is found that background values of the specific/volumetric activity of radionuclides are much lower than admissible values of NRB‐99/2009 and are at the level of the previous years (2009–2014). The results of the studies will be the basis for precision tool estimates of the effect of the Baltic NPP operation on the environment and will also be used to establish background values of environmental parameters in the area of the nuclear power plant.

Keywords: Neman River, Baltic NPP, technogenic radionuclides, tritium, radioactivity, global background, surface waters, bottom sediments, hydrobionts.
