Physical-chemical method for desalting organic waste for agricultural cycles / S. V. Trifonov, A. V. Murygin, A. A. Tikhomirov // IOP Conference Series: Earth and Environmental Science : IOP Publishing Ltd, 2021. - Vol. 839: 5th International Scientific Conference on Agribusiness, Environmental Engineering and Biotechnologies, AGRITECH-V 2021 (16 June 2021 through 19 June 2021, ) Conference code: 172484, Is. 4. - Ст. 042062, DOI 10.1088/1755-1315/839/4/042062
Аннотация: The problem of developing a technology for the removal or drastic reduction of NaCl from organic waste, including human exometabolites and plant waste and intended for disposal in closed agricultural cycles, is very relevant, especially for Northern regions with risky agriculture. Without its solution, it becomes almost impossible to create a long-term functioning ecosystem due to the danger of accumulation of NaCl in irrigation solutions and soil with subsequent poisoning of plants. It is obvious that the development of the technology for extracting NaCl is most rational to perform in combination with the technology for processing human exometabolites, since they are the main source of NaCl. © Published under licence by IOP Publishing Ltd.

Ciliates -- Meromictic lakes -- Chemocline -- Meromixis breakdown
Аннотация: The study deals with the vertical distribution and seasonal dynamics of planktonic ciliates in the pelagic and littoral zones of a saline meromictic Lake Shira. Fourteen species of free-living ciliates have been found in the Lake, seven of them inhabiting the pelagic zone. The richness of ciliates is higher both in terms of the number of species and biomass in the littoral zone compared to the pelagic zone. Although the ciliate species diversity is low in the pelagic zone, in certain seasons, the biomass of some of the species may reach considerable values, up to 3.4 g m(-2) in the water column. The biomass of ciliates in Lake Shira is generally comparable to the average values for other mesotrophic lakes. The abundance and composition of ciliate populations in Lake Shira vary considerably with depth. Changes in the Lake ecosystem caused by meromixis breakdown in 2015-2016, which induced considerable variations in many Lake components, affected the vertical distribution of planktonic ciliates. However, the annual average biomass of the species that inhabited the Lake before meromixis breakdown remained unchanged. The total ciliate biomass increased due to the presence of the new species.

Transfer efficiency of carbon, nutrients, and polyunsaturated fatty acids in planktonic food webs under different environmental conditions / M. Karpowicz, I. Feniova, M. I. Gladyshev [et al.] // Ecology and Evolution. - 2021, DOI 10.1002/ece3.7651 . - Article in press. - ISSN 2045-7758

Аннотация: The trophic transfer efficiency (TTE) is an important indicator of ecosystem functioning. However, TTE data from freshwater food webs are ambiguous due to differences in time scales and methods. We investigated the transfer of essential substances (carbon, nutrients, and polyunsaturated fatty acids) through plankton communities in 30 Polish lakes with different trophic status in the middle of summer. The results of our study revealed that different essential substances were transferred from phytoplankton to zooplankton with varying efficiencies. The average TTE of C, N, P, and the sum of ?-3 PUFA were 6.55%, 9.82%, 15.82%, and 20.90%, respectively. Our results also show a large mismatch between the elemental and biochemical compositions of zooplankton and their food during the peak of the summer stagnation, which may further promote the accumulation of essential substances. There were also large differences in TTEs between trophic conditions, with the highest efficiencies in oligotrophic lakes and the lowest in dystrophic and eutrophic lakes. Therefore, our study indicates that disturbances like eutrophication and dystrophication similarly decrease the TTE of essential substances between phytoplankton and zooplankton in freshwater food webs. © 2021 The Authors.

Аннотация: The present study investigates, for the first time, the structure of the microbial community of cryogenic soils in the subarctic region of Siberia and the ability of the soil microbial community to metabolize degradable microbial bioplastic – poly-3-hydroxybutyrate [P(3HB)]. When the soil thawed, with the soil temperature between 5-7 and 9–11 °C, the total biomass of microorganisms at a 10-20-cm depth was 226–234 mg g?1 soil and CO2 production was 20–46 mg g?1 day?1. The total abundance of microscopic fungi varied between (7.4 ± 2.3) ? 103 and (18.3 ± 2.2) ? 103 CFU/g soil depending on temperature; the abundance of bacteria was several orders of magnitude greater: (1.6 ± 0.1) ? 106 CFU g?1 soil. The microbial community in the biofilm formed on the surface of P(3HB) films differed from the background soil in concentrations and composition of microorganisms. The activity of microorganisms caused changes in the surface microstructure of polymer films, a decrease in molecular weight, and an increase in the degree of crystallinity of P(3HB), indicating polymer biodegradation due to metabolic activity of microorganisms. The clear-zone technique – plating of isolates on the mineral agar with polymer as sole carbon source – was used to identify P(3HB)-degrading microorganisms inhabiting cryogenic soil in Evenkia. Analysis of nucleotide sequences of rRNA genes was performed to identify the following P(3HB)-degrading species: Bacillus pumilus, Paraburkholderia sp., Pseudomonas sp., Rhodococcus sp., Stenotrophomonas rhizophila, Streptomyces prunicolor, and Variovorax paradoxus bacteria and the Penicillium thomii, P. arenicola, P. lanosum, Aspergillus fumigatus, and A. niger fungi. © 2020 Elsevier Ltd

Аннотация: This article presents the history of large oil spills in freshwaters, considering the processes of physicochemical and biological degradation of oil. It discusses the toxicity of oil for hydrobionts and effects of oil pollution on communities of plankton, benthos, and ichthyofauna, as well as challenges in mitigating the environmental impact of oil spills. The discussion is concerned with the state of the ecosystem in Lake Pyasino before the incidental spill of 2020, specifically, hydrochemical indicators; species composition; and abundance and biomass of plankton, benthos, and fish. Candidate technologies for restoring the Lake Pyasino ecosystem are reviewed, including "bottom-up" biomanipulation.

Аннотация: An assessment of the species composition, abundance, biomass, and pigment characteristics of phytoperiphyton and phytoplankton of Lake Pyasino, its tributaries (Bezymyannyi Stream, Daldykan, Ambarnaya, and Norilskaya rivers), and the head of the Pyasina River has been carried out after a manmade accident (a diesel-fuel spill near the city of Norilsk in May 2020). A significant decline in the biomass and changes in the species composition of phytoperiphyton after the water was contaminated by fuel is revealed only near the spillage site (in the Daldykan River and the Ambarnaya River downstream the mouth of the Daldykan). Downstream, in the Ambarnaya mouth zone, as a response to the release of a large amount of nutrients during the decomposition of fuel products and dead organisms, as well as the mechanical cleaning of the bank line, there has been a massive growth of diatom and green algae (Tabularia tabulata, Spirogyra sp.) in the water column and the appearance of indicators of organic pollution (Euglenophyceae and Cryptophyceae). No significant changes in the plankton of Lake Pyasino and the Pyasina River in comparison with the data obtained in the second half of the 20th century (i.e., long before the accident) are found. Species composition and quantitative features, as well as amount and ratio of pigments, characterized the phytoplankton and phytoperiphyton of Lake Pyasino and the Pyasina River as a normally functioning freshwater community of oligotrophic waters. All this indicates the absence of a negative impact of the accidental fuel spill on the ecosystem of Lake Pyasino and the Pyasina River.

Аннотация: The efficiency of the transfer of carbon, polyunsaturated fatty acids (PUFA), nitrogen and phosphorus from phytoplankton to zooplankton determines the functioning of the entire ecosystem. However, this parameter depends on environmental conditions. Fish as a very important factor to regulate planktonic communities are very likely to affect the efficiency of the transfer of basic elements and substances from phytoplankton to zoo plankton. In experimental mesocosms filled with water from an eutrophic lake and containing phyto- and zooplankton, we investigated how fish affect both primary and secondary production and the efficiency of transfer of carbon, nitrogen, phosphorus, PUFA and fatty acids (FA) from phytoplankton to zooplankton. Two treatments (control and fish treatment) were repeated in three replicates. The transfer efficiency of substances from phytoplankton to zooplankton was measured as the ratio of secondary to primary production, expressed in liters and per biomass unit in percent. The efficiency expressed per liter characterizes the productivity of the water body, while the efficiency expressed per biomass unit indicates the effectiveness of aquatic species to transfer biologically valuable substances from one trophic level to another. We found that phytoplankton-zooplankton-fish interactions are determined not only by predator-prey relationships, but also are affected by the quality of both phytoplankton and zooplankton, measured as the contents of phosphorus, nitrogen, PUFA and FA in their biomass. We showed that, in the presence of fish, the transfer efficiency of carbon, phosphorus, nitrogen, eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), FA per biomass unit from phytoplankton to zooplankton was increased two-fold, 12.4-fold, 2,5-fold, 12.4-fold, 7.4-fold, and 10-fold, respectively, relative to control. This provides the sustainability of the functioning of the ecosystem under fish pressure. Such a mechanism prevents zooplankton over-exploitation by fish and enables to prolong the food chain.

Аннотация: Long-term research has revealed layers with abnormally high concentrations of Cs-137 in bottom sediments and alluvial soils in the floodplain of the Yenisei River at various distances (as far as 820 km) downstream from the radioactive discharge point of the Mining-and-Chemical Combine (MCC) of Rosatom. The highest activity concentration of Cs-137 in these layers reached 26 000 Bq/kg, which was higher than the Cs-137 maximum at the well-known radioactive anomaly in the Yeniseisk riparian zone (330 km downstream from the MCC), which was formed during the 1966 extreme flood event. The radionuclide composition and the Cs-137/Eu-152 and Cs-137/Co-60 ratios in the anomalous layers studied were the same as those at the Yeniseisk anomalous site, suggesting that they had the same origin by the transport of sediments from the MCC area during the 1966 extreme flood event. The transport of radioactive bottom sediments over long distances from the MCC discharge point downstream along the Yenisei River during the 1966 extreme flood event may continue to pose a possible radiation hazard to the river ecosystem and residents of riverside villages.

Global data set of long-term summertime vertical temperature profiles in 153 lakes / R. M. Pilla, E. M. Mette, C. E. Williamson [et al.] // Sci. Data. - 2021. - Vol. 8, Is. 1. - Ст. 200, DOI 10.1038/s41597-021-00983-y . - ISSN 2052-4463
Аннотация: Climate change and other anthropogenic stressors have led to long-term changes in the thermal structure, including surface temperatures, deepwater temperatures, and vertical thermal gradients, in many lakes around the world. Though many studies highlight warming of surface water temperatures in lakes worldwide, less is known about long-term trends in full vertical thermal structure and deepwater temperatures, which have been changing less consistently in both direction and magnitude. Here, we present a globally-expansive data set of summertime in-situ vertical temperature profiles from 153 lakes, with one time series beginning as early as 1894. We also compiled lake geographic, morphometric, and water quality variables that can influence vertical thermal structure through a variety of potential mechanisms in these lakes. These long-term time series of vertical temperature profiles and corresponding lake characteristics serve as valuable data to help understand changes and drivers of lake thermal structure in a time of rapid global and ecological change. © 2021, The Author(s).

Аннотация: The efficiency of the transfer of carbon, polyunsaturated fatty acids (PUFA), nitrogen, and phosphorus from phytoplankton to zooplankton determines the functioning of the entire ecosystem. However, this parameter depends on environmental conditions. Fish as a very important factor regulating planktonic communities very likely affect the efficiency of the transfer of basic elements and substances from phytoplankton to zooplankton. In experimental mesocosms filled with water from a eutrophic lake and containing phyto- and zooplankton, we investigated how fish affect both primary and secondary production and the efficiency of transfer of carbon, nitrogen, phosphorus, PUFA, and fatty acids (FAs) from phytoplankton to zooplankton. Two treatments (control and fish treatment) were repeated in three replicates. The transfer efficiency of substances from phytoplankton to zooplankton was measured as the ratio of secondary production to primary production expressed per L and per unit of biomass. The efficiency expressed per L characterizes the productivity of the water body, while the efficiency expressed per unit of biomass indicates the effectiveness of aquatic species to transfer biologically valuable substances from one trophic level to another. We found that phytoplankton-zooplankton-fish interface is determined not only by predator-prey relationships, but are also affected by the quality of both phytoplankton and zooplankton in terms of contents of phosphorus, nitrogen, PUFA, and FAs in their biomass. We showed that, in the presence of fish, the transfer efficiency of carbon, phosphorus, nitrogen, eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and FAs per unit of biomass from phytoplankton to zooplankton was increased twofold, 12.4-fold, 2.5-fold, 12.4-fold, 7.4-fold, and tenfold, respectively, relative to the control. This facilitates sustainable functioning of the ecosystem under fish pressure. Such a mechanism prevents zooplankton over-exploitation by fish and enlarges the food chain.

Аннотация: The trophic transfer efficiency (TTE) is an important indicator of ecosystem functioning. However, TTE data from freshwater food webs are ambiguous due to differences in time scales and methods. We investigated the transfer of essential substances (carbon, nutrients, and polyunsaturated fatty acids) through plankton communities in 30 Polish lakes with different trophic status in the middle of summer. The results of our study revealed that different essential substances were transferred from phytoplankton to zooplankton with varying efficiencies. The average TTE of C, N, P, and the sum of omega-3 PUFA were 6.55%, 9.82%, 15.82%, and 20.90%, respectively. Our results also show a large mismatch between the elemental and biochemical compositions of zooplankton and their food during the peak of the summer stagnation, which may further promote the accumulation of essential substances. There were also large differences in TTEs between trophic conditions, with the highest efficiencies in oligotrophic lakes and the lowest in dystrophic and eutrophic lakes. Therefore, our study indicates that disturbances like eutrophication and dystrophication similarly decrease the TTE of essential substances between phytoplankton and zooplankton in freshwater food webs.

Аннотация: This review of trends in inland saline lakes of Europe and Central Asia is based on the relevant section of the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) Regional Assessment Report for Europe and Central Asia (ECA). We assessed the present status of ECA saline lakes and the effects of direct drivers (climate change, land use, pollution, resource exploitation, invasive species) on ecosystem health and biodiversity. We also assessed past, current and future trends using habitat area and degradation, species richness, and endangered species as indicators. No uniform scenario is applicable to saline lakes in the region. The desiccation of the Aral Sea is caused mainly by land use change and water extraction. In the Caspian Sea, river modifications, water pollution, overfishing and poaching, and species invasions have led to a decrease in species richness and have threatened endemic species. Although trends for smaller saline lakes vary, our analysis demonstrates that land use change, over-exploitation, and pollution are more important direct drivers of ecosystem health and biodiversity than climate change. The establishment of baseline biodiversity values for saline lakes is, however, complicated because biodiversity and the food-web structure are variable and depend strongly on salinity. Thus, there is a need to classify the ecological quality, biodiversity and ecosystem services of saline lakes along a salinity gradient. The improvement of water management and reuse of water, conservation measures, and introduction of climate-smart agriculture are basic conditions for the sustainable use of saline lakes in the region.

The effect of deicing salt solutes on Moina macrocopa and Allium cepa in a toxicity test experiment / T. S. Lopatina, Y. V. Aleksandrova, O. V. Anishchenko [и др.] // Vestn. Tomsk. Gos. Univ. Biol. - 2020. - Is. 51. - С. 162-178, DOI 10.17223/19988591/51/9 . - ISSN 1998-8591
Кл.слова (ненормированные):
Aquatic ecosystems -- Cladocera, Allium-test -- Salinity -- Toxicity test
Аннотация: Chloride salts are the most commonly used deicing materials for winter maintenance of roads. Numerous studies indicate a significant increase in the salinity of aquatic ecosystems associated with the long-term use of deicing materials in countries located in cold climates. The functioning of ecosystems largely depends on salinity, since salinity is one of the key factors determining the species composition, the structure of food webs and the productivity of aquatic communities. Given the growing threat of salinization of groundwater and surface waters, it is extremely important to study the effect of deicing materials on the biota and functioning of aquatic ecosystems. The aim of this research is to determine the threshold concentrations of solutions of the deicing salt mixture “Bionord” containing sodium and calcium chlorides, at which negative effects on the development of animal and plant test objects are observed. In this study, we used the salt-containing mixture “Bionord” as a model deicer. Similarly, with the most commonly used ice melting chemicals, the «Bionord» salt mixture contains a large amount of sodium and calcium chlorides (about 85% of the total weight). To evaluate the toxicity of the deicer solutions, we used acute and chronic toxicity tests with cladoceran Moina macrocopa (Straus, 1820) (Cladocera: Moinidae) and standard onion-based test with Allium cepa L. (Liliopsida: Amaryllidaceae) (Allium-test). In acute and chronic toxicity tests with Cladocera, the females on the first day of their life (body size 0.5-0.6 mm) were placed individually in jars with aged (not less than for 72 h) tap water with a volume of 20 ml with the addition of a deicer at a certain concentration. A group of animals that was placed in the medium without the deicer was used as a control. In the acute toxicity tests, we used the following concentration of the deicer: 1.3; 2.5; 4.0, 5.0; 6.0; 8.0; 10.0 g/l. The mortality of animals was recorded 24 and 48 hours after the start of the experiment. The concentration of the deicer (LC50) at which 50% of animals was observed to die, compared to the control, was determined in the acute toxicity test. In a chronic toxicity test, animals were tested in the following range of concentrations of the deicer: 0.3; 0.6; 1.3; 2.5; 5.0; 6.0 and 8.0 g/l. The chronic toxicity test was conducted until the death of all test animals. Based on the data obtained in the chronic toxicity test, the specific growth rate of juvenile females, average fecundity, and average life span of M. macrocopa were calculated for each concentration of the deicer. Bulbs of onions of the Stuttgartenrisen variety with a diameter of 1.8 ± 0.1 cm and a weight of 2.27 ± 0.17 g were used in the onion test. Bulbs with their bottoms were placed in test tubes containing 20 ml of a solute of the deicer or tap water for 48 hours. Three bulbs were tested for each concentration and for the control. The following concentrations of the deicer were used in the onion test: 1.0; 2.5; 5.0; 7.0; 10.0; 15.0; 20.0; 50.0 g/l. The general toxic and cytotoxic effects were evaluated in the onion test. The average root length and the total root length on each bulb were used as indicators of the total toxicity of the solutions of deicer. To evaluate proliferative activity, we calculated the mitotic index as the fraction of dividing cells in the apical root meristem to the total number of cells. Based on the results of the experiments, we determined median effective mixture concentrations (EC50) at which there is a 50% decrease, compared to the control, in the values of root growth indicators: average root length, sum of root lengths on each bulb and mitotic index. Median lethal concentration (LC50) of the deicing salt determined in the 48-hour acute toxicity test with females of M. macrocopa was equal to 5.1 g/l. In the chronic test, we showed that the exposure to the solutions of the deicing salt in the range of concentrations from 0.3 to 5.0 g/l does not affect the life span, specific growth rate of juveniles and fecundity of females of M. macrocopa. The median effective concentration (EC50) of the deicing salt determined in the Allium-tests were 6.3, 5.2 and 10.4 g/l for the sum of root lengths, average root length on each bulb and proliferative activity at the tips of roots (mitotic index), respectively (See Table 1 and 2). Complete inhibition of onion root growth was observed at the concentration of the decider equal to 20 g/l, while the death of all test animals in the acute toxicity test occurred at the concentration of the deicer equal to 8,0 g/l (See Fig. 1). Thus, we demonstrated that similar concentrations of the deicer induced 50% inhibition of the growth of onion roots and 50% mortality of cladocerans. These values, in general, corresponded to a critical salinity of 5-8 % above which qualitative changes occur both in the external and internal condition of aquatic animals. The electrical conductivity of the deicer solutions, which had a negative effect on the selected test species, coincides with the previously obtained values of the electrical conductivity of sodium chloride solutions harmful to cladocerans. We can assume that the main mechanism of the effect of the deicing material that we study is associated with the biological effect of its chlorine and sodium salts. Taking this into account, the value of electrical conductivity measured for solutions of deicing salt can be used to assess its negative potential effects. We estimated that in the absence of timely cleaning, regulated by the rules for using the material, the runoff from each square meter of the treated surface can lead to the pollution of 8-13 liters of fresh water. Thus, the basic requirement for the use of deicing salts on roads is the need to comply with the cleaning regime of the treated surfaces. Otherwise, the gradual accumulation of sodium and calcium chlorides in water bodies can cause an increase in salinity which will affect the survival of freshwater aquatic organisms and lead to serious disturbances in the functioning of aquatic ecosystems. © 2020 Tomsk State University.

Spatial and temporal variation in Arctic freshwater chemistry—Reflecting climate-induced landscape alterations and a changing template for biodiversity / B. J. Huser, M. N. Futter, D. Bogan [et al.] // Freshw. Biol. - 2020, DOI 10.1111/fwb.13645 . - Article in press. - ISSN 0046-5070

biogeochemistry -- eutrophication -- lakes -- oligotrophication -- rivers
Аннотация: Freshwater chemistry across the circumpolar region was characterised using a pan-Arctic data set from 1,032 lake and 482 river stations. Temporal trends were estimated for Early (1970–1985), Middle (1986–2000), and Late (2001–2015) periods. Spatial patterns were assessed using data collected since 2001. Alkalinity, pH, conductivity, sulfate, chloride, sodium, calcium, and magnesium (major ions) were generally higher in the northern-most Arctic regions than in the Near Arctic (southern-most) region. In particular, spatial patterns in pH, alkalinity, calcium, and magnesium appeared to reflect underlying geology, with more alkaline waters in the High Arctic and Sub Arctic, where sedimentary bedrock dominated. Carbon and nutrients displayed latitudinal trends, with lower levels of dissolved organic carbon (DOC), total nitrogen, and (to a lesser extent) total phosphorus (TP) in the High and Low Arctic than at lower latitudes. Significantly higher nutrient levels were observed in systems impacted by permafrost thaw slumps. Bulk temporal trends indicated that TP was higher during the Late period in the High Arctic, whereas it was lower in the Near Arctic. In contrast, DOC and total nitrogen were both lower during the Late period in the High Arctic sites. Major ion concentrations were higher in the Near, Sub, and Low Arctic during the Late period, but the opposite bulk trend was found in the High Arctic. Significant pan-Arctic temporal trends were detected for all variables, with the most prevalent being negative TP trends in the Near and Sub Arctic, and positive trends in the High and Low Arctic (mean trends ranged from +0.57%/year in the High/Low Arctic to ?2.2%/year in the Near Arctic), indicating widespread nutrient enrichment at higher latitudes and oligotrophication at lower latitudes. The divergent P trends across regions may be explained by changes in deposition and climate, causing decreased catchment transport of P in the south (e.g. increased soil binding and trapping in terrestrial vegetation) and increased P availability in the north (deepening of the active layer of the permafrost and soil/sediment sloughing). Other changes in concentrations of major ions and DOC were consistent with projected effects of ongoing climate change. Given the ongoing warming across the Arctic, these region-specific changes are likely to have even greater effects on Arctic water quality, biota, ecosystem function and services, and human well-being in the future. © 2020 The Authors.

Experimental model of the closed ecosystem -- Oxidation of human and plant -- wastes -- Plant productivity -- Cycling
Аннотация: The purpose of this study was to investigate mass exchange processes in the experimental model of a closed ecological system intended for an estimated portion of a human in the long-duration (several-month) experiment. The diversity of the vegetable crop community in the system was increased, human wastes were involved in mass exchange processes, and human respiration was periodically connected to the system. The system has been designed to test different prospective technologies for future closed life support systems intended for prolonged autonomous operation in space and terrestrial applications. Three methods of plant cultivation in the conveyer mode have been used: hydroponics on expanded clay aggregate, growing plants on the soil-like substrate, and plant cultivation in aquaculture. The technology of more effective oxidation of organic wastes in a physicochemical processing reactor has been developed. A human exhaled the air into the system and consumed the air from the system. O-2 concentration did not drop below 20.8% and did not rise above 22.6%. CO2 concentration varied between 800 ppm and 2500 ppm. Plants growing under this CO2 range at a preset light irradiance showed optimal photosynthetic activity. The closure coefficients for Ca, Mg, S, N, K and P were above 90%. However, compared with the inflow, only 55% Ca, about 80% Mg, and 75% Na and P were removed from the system. The technological processes developed in this study will need to be modified and improved before they can be used in a full-scale closed biotechnical life support system intended for prolonged operation.

Аннотация: The contents of isotopes of plutonium (Pu-238 and(239, 240)Pu) and(137)Cs in samples of bottom sediments and hydrobionts (water moss, amphipods, and caddisfly larvae with casings) taken in the Yenisei River in the vicinity of the radioactive discharge from the Mining and Chemical Combine in 2012 and 2018 were comparatively estimated. It is shown that the content and ratios between the specific activities of plutonium isotopes (238/239 and 240) in samples of BSs and hydrobionts increased after the recommencing of plutonium discharges into the Yenisei due to the beginning of MOX fuel production. The background content and the ratio between plutonium isotopes in BSs of the Yenisei were estimated for the first time. Hydrobionts and BSs were ranged differently according to the content of plutonium and(137)Cs: we recorded the highest content of(137)Cs in BSs and that of plutonium in water moss. The plutonium content in hydrobionts of the Yenisei River varies considerably, which permits specification of representatives of biota (water moss and caddisfly larvae with casings) that, along with BSs, can be used as effective indicators of ecosystem pollution with plutonium.

Community structure and vertical distribution of planktonic ciliates in the saline meromictic lake Shira during breakdown of meromixis / E. B. Khromechek, Y. V. Barkhatov, D. Y. Rogozin // Ecohydrol. Hydrobiol. - 2020, DOI 10.1016/j.ecohyd.2020.08.001 . - Article in press. - ISSN 1642-3593

Chemocline -- Ciliates -- Meromictic lakes -- Meromixis breakdown
Аннотация: The study deals with the vertical distribution and seasonal dynamics of planktonic ciliates in the pelagic and littoral zones of a saline meromictic Lake Shira. Fourteen species of free-living ciliates have been found in the Lake, seven of them inhabiting the pelagic zone. The richness of ciliates is higher both in terms of the number of species and biomass in the littoral zone compared to the pelagic zone. Although the ciliate species diversity is low in the pelagic zone, in certain seasons, the biomass of some of the species may reach considerable values, up to 3.4 g m?2 in the water column. The biomass of ciliates in Lake Shira is generally comparable to the average values for other mesotrophic lakes. The abundance and composition of ciliate populations in Lake Shira vary considerably with depth. Changes in the Lake ecosystem caused by meromixis breakdown in 2015-2016, which induced considerable variations in many Lake components, affected the vertical distribution of planktonic ciliates. However, the annual average biomass of the species that inhabited the Lake before meromixis breakdown remained unchanged. The total ciliate biomass increased due to the presence of the new species. © 2020 Elsevier Ltd

Аннотация: Globally, lake surface water temperatures have warmed rapidly relative to air temperatures, but changes in deepwater temperatures and vertical thermal structure are still largely unknown. We have compiled the most comprehensive data set to date of long-term (1970-2009) summertime vertical temperature profiles in lakes across the world to examine trends and drivers of whole-lake vertical thermal structure. We found significant increases in surface water temperatures across lakes at an average rate of+0.37 degrees C decade(-1), comparable to changes reported previously for other lakes, and similarly consistent trends of increasing water column stability (+0.08 kg m(-3) decade(-1)). In contrast, however, deepwater temperature trends showed little change on average (+0.06 degrees C decade(-1)), but had high variability across lakes, with trends in individual lakes ranging from -0.68 degrees C decade(-1) to+0.65 degrees C decade(-1). The variability in deepwater temperature trends was not explained by trends in either surface water temperatures or thermal stability within lakes, and only 8.4% was explained by lake thermal region or local lake characteristics in a random forest analysis. These findings suggest that external drivers beyond our tested lake characteristics are important in explaining long-term trends in thermal structure, such as local to regional climate patterns or additional external anthropogenic influences.
