Аннотация: At the beginning of August, 2 months after 20 000 t of diesel fuel spilled into the Bezymyanny Stream (which took it out to the Daldykan and Ambarnaya rivers), the large Norilsk expedition of the Siberian Branch, Russian Academy of Sciences, sampled net zooplankton at 13 stations located in both sections of these rivers and Lake Pyasino with the Pyasina River outflowing from it. A comparative analysis of the species composition, abundance, biomass, and saprobity index of zooplankton at these stations has been carried out. The productions of rotifer and crustacean zooplankton and potential production of planktivorous fish in Lake Pyasino have been calculated. Based on the state of zooplankton, a gradual improvement in water quality has been observed from river areas exposed to the oil products to the northern part of the lake and the River Pyasina outflow. The low abundance and biomass of zooplankton in the lake (43 800 +/- 17 550 ind./m(3), 112.8 +/- 26.2 mg/m(3), on average) due to the dominance of rotifers (Ploesoma truncatum (Levander), Bipalpus hudsoni (Imhof), and Conochilus unicornis Rousselet) resulted in low values of zooplankton production and the potential production of planktivorous fish (0.85 kg/ha per season).

Кл.слова (ненормированные):
zoobenthos -- species composition -- abundance -- biomass -- production -- fish -- productivity -- oil spills -- water quality
Аннотация: The species composition and quantitative characteristics of the zoobenthos in Lake Pyasino and rivers flowing into it after a diesel spill have been analyzed. The production of zoobenthos and potential production of benthivorous fish in Lake Pyasino have been calculated. A small number of zoobenthos species and low values of abundance and biomass are revealed. In the Bezymyanny Stream, the mouth of the Daldykan River, and the Ambarnaya River, oligochaetes Limnodrilus hoffmeisteri Claparede and Tubifex tubifex (O. F. Muller) dominate in the zoobenthos abundance and biomass. In Lake Pyasino and the Pyasina River outflow, larvae of caddis flies, chironomids, stoneflies, and amphipods prevail. In the area of the deepwater silted station of Lake Pyasino, oligochaetes L.hoffmeisteri develop, the proportion of which in the benthic fauna at this station (40 and 79% of the total biomass and abundance, respectively) is maximal. The amphipod Monoporeia affinis (Lindstrom) dominates in terms of biomass at this station. A decrease in the chironomid diversity, an increase in the proportion of polysaprobic oligochaetes, and lower values of the Shannon index in Lake Pyasino in 2020 when compared to 1992 are found. The low abundance (2181 +/- 2048 ind./m(2)) and biomass (2.01 +/- 1.85 g/m(2)) of zoobenthos in the lake results in low values of zoobenthos production and the potential production of benthivorous fish (3 kg/ha per season). Based on the state of zoobenthos, an improvement in water quality has been observed from river sections exposed to the oil spill to the lake and the source of the River Pyasina.

Аннотация: The paper considers a new approach to modeling the relationship between the increase in woody phytomass in the pine forest and satellite-derived Normalized Difference Vegetation Index (NDVI) and Land Surface Temperature (LST) (MODIS/AQUA) data. The developed model combines the phenological and forest growth processes. For the analysis, NDVI and LST (MODIS) satellite data were used together with the measurements of tree-ring widths (TRW). NDVI data contain features of each growing season. The models include parameters of parabolic approximation of NDVI and LST time series transformed using principal component analysis. The study shows that the current rate of TRW is determined by the total values of principal components of the satellite indices over the season and the rate of tree increment in the preceding year.

Winter atmospheric nutrient and pollutant deposition on Western Sayan Mountain lakes (Siberia) / D. Diaz-De-Quijano, A. Vladimirovich Ageev, E. Anatolevna Ivanova, O. Valerevna Anishchenko // Biogeosciences. - 2021. - Vol. 18, Is. 5. - P1601-1618, DOI 10.5194/bg-18-1601-2021 . - ISSN 1726-4170
Аннотация: The world map of anthropogenic atmospheric nitrogen deposition and its effects on natural ecosystems is not described with equal precision everywhere. In this paper, we report atmospheric nutrient, sulfate and spheroidal carbonaceous particle (SCP) deposition rates, based on snowpack analyses of a formerly unexplored Siberian mountain region. Then, we discuss their potential effects on lake phytoplankton biomass limitation. We estimate that the nutrient depositions observed in the late-season snowpack (4016 mgNO3-Nm2 and 0.580.13 mg TP-Pm2; TP for total phosphorous) would correspond to yearly depositions lower than 11971 mgNO3-Nm2 yr1 and higher than 1.710.91 mg TP-Pm2 yr1. These yearly deposition estimates would approximately fit the predictions of global deposition models and correspond to the very low nutrient deposition range, although they are still higher than world background values. In spite of the fact that such a low atmospheric nitrogen deposition rate would be enough to induce nitrogen limitation in unproductive mountain lakes, phosphorus deposition was also extremely low, and the resulting lake water N: P ratio was unaffected by atmospheric nutrient deposition. In the end, the studied lakes' phytoplankton appeared to be split between phosphorus and nitrogen limitation. We conclude that these pristine lakes are fragile sensitive systems exposed to the predicted climate warming, increased winter precipitation, enhanced forest fires and shifts in anthropogenic nitrogen emissions that could finally couple their water chemistry to that of atmospheric nutrient deposition and unlock temperature-inhibited responses of phytoplankton to nutrient shifts. © Author(s) 2021.

The use of the data derived from the PlanetScope satellite and unmanned aerial vehicles to estimate crop yield as dependent on the amount of nitrogen fertilizer applied / N. O. Malchikov, T. I. Pisman, I. Y. Botvich [et al.] // 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. 2. - Ст. 022004, DOI 10.1088/1755-1315/839/2/022004
Аннотация: The purpose of the present study is to show the usefulness of the satellite data and the data derived from unmanned aerial vehicles (UAVs) for estimating the relationship between cereal grain crop yield and the amount of nitrogen fertilizer applied. The study was conducted on the land of the Kuraginskoye Research Farm. The study material was spring barley cv. Biom. Three test plots were studied; mineral fertilizer, urea, was used in different quantities for foliar application in June; applications were performed at equal intervals. Multispectral images were based on PlanetScope satellite data, with the 3 m spatial resolution, and the data derived from the DJI Phantom 4 Multispectral UAV, with the 10 cm resolution. The satellite and UAV data were used to calculate spectral vegetation index (NDVI) (Normalized Difference Vegetation Index). A high correlation was obtained between the NDVI values calculated using satellite data and UAV data. The satellite data provided the basis for assessing barley crop yield as dependent on the amount of foliar-applied urea during the growing season. Maps of the spatial distribution of barley NDVI were constructed using the Phantom UAV data; they showed that the third foliar application of the fertilizer was not economically justified. © Published under licence by IOP Publishing Ltd.

Аннотация: This paper presents the results of a study assessing the degree of weed infestation of wheat crops. They are obtained using optical ground-based and satellite spectral data with a 3-m spatial resolution from PlanetScope Dove satellites for 2019. The vegetation indices, including the normalized difference vegetation index (NDVI), the relative chlorophyll index (Chlorophyll Index Green-ClGreen or GCI), the modified soil-adjusted vegetation index (MSAVI2), and the visible atmospherically resistant index (VARI) are used in the interpretation of ground-based spectrometric and space images. This paper indicates the possibility of assessing the degree of weed infestation of agricultural fields. The higher the weed infestation, the lower the index values. The dynamics of VARI is found to be different from the dynamics of NDVI, ClGreen, and MSAVI2 during the growing season. The strong correlation between NDVI, ClGreen, and MSAVI2 and the weak correlation between VARI and other indices are observed. The possibility of identifying weedy sites in the agricultural fields is shown using the spatial distribution map of ClGreen dated August 2, 2019.

Аннотация: The proposed approach allows us to evaluate the response of forest stands to local weather changes and resistance to insect attack without using data from weather stations, sometimes located far from experimental forest areas. All raw data were obtained during the season using remote sensing data (MODIS / AQUA). The ability to pre-determine decrease and loss of forest stands resistance to possible insect attacks can be extremely important for solving the tasks of forest-entomological monitoring and calculating the risk of forest insect's outbreaks. © Published under licence by IOP Publishing Ltd.

Аннотация: Accumulation of essential/beneficial and non-essential chemical elements by submerged (Stuckenia pectinata (L.) Borner) and emergent (Phragmites australis (Cay.) Trin. ex Steud.) rooted macrophytes in three water bodies was studied as dependent on water salinity (specific conductivity) and main environmental factors (temperature, pH of water, growing period, element contents in water and sediments). Inductively coupled plasma optical emission spectrometry (ICP - OES) was used for the element detection in the plants, sediments, and water. Multivariate statistics redundancy analysis (RDA) showed that investigated factors together explained 37.8 44.7% and 29.9 - 42.6% of the essential/beneficial and non-essential elements variability, respectively, whereas salinity was one of the main factors determining the accumulation of a number of elements (Mg, S, Na, Li, Sr, Sb) by the macrophytes. A decrease in the essential element contents (K, P, N, Cu, Zn) was observed in both species of the macrophytes during the growing season. Environmental factors (salinity, growing period, and pH) were more significant than the element contents in water and the sediments for the essential/beneficial element accumulation by two species of the macrophytes. The element contents in the sediments to a greater extent determined non-essential element accumulation by P. australis than by S. pectinata. The study showed that the efficiency of using P. australis and S. pectinata for remediation of aquatic ecosystems contaminated by heavy metals should not decrease with a salinity increase.

Аннотация: Successful incorporation of soil-like substrate (SLS) into biotechnical life support systems is often complicated by the necessity to maintain the balance between flows of mineral elements taken up from the substrate by growing plants and mineral elements added to the SLS as components of mineralized plant inedible biomass. An imbalance between these two flows can be caused by the addition of recalcitrant plant waste such as wheat straw. The purpose of this study was to determine whether the availability of essential nutrients to be taken up by the roots of the wheat plants grown on the SLS could be enhanced by supplementing the SLS with the products derived from wheat straw subjected to different levels of physicochemical mineralization in the aqueous solution of hydrogen peroxide. Different degrees of straw mineralization were achieved by using different ratios of the aqueous solution of hydrogen peroxide to straw. The study showed that supplementation of the SLS with insufficiently oxidized products of physicochemical mineralization of straw resulted in a decrease in the grain yields. The inhibitory effect of the straw subjected to physicochemical oxidation increased with a decrease in the degree to which the straw had been oxidized. Only supplementation with the straw mineralized to the highest possible degree did not inhibit plant growth and development, and the crop yield in that treatment was higher than in the other treatments. © 2020

bare fallows -- Keywords: sod fields -- NDSI -- NDVI -- Sentinel-2
Аннотация: Abstract—The results of satellite monitoring of vegetation on unused agricultural lands during the growing season of 2018 are presented. Sod fields of different ages (2, 7, and 20 years) and bare fallows on the land used by the Krasnoyarsk Research Institute of Agriculture were the objects of the study. Satellite data with high spatial resolution (Sentinel-2 Earth remote sensing satellites) at the pre-processing Level-1C (https://earthexplorer.usgs.gov/) were used for the interpretation of sod field and fallow images. These data were used to calculate the Normalized Difference Vegetation Index (NDVI) and the Normalized Difference Soil Index (NDSI). Algorithms and software for the processing of Sentinel-2 satellite data were developed. The possibility of using NDVI dynamics for assessment and monitoring of the condition of sod fields and bare fallows has been demonstrated. The applicability of the NDSI soil index for assessment of the status of arable land has been demonstrated. © 2019, Pleiades Publishing, Inc.

Barley -- Crop yield -- Growing season -- PlanetScope -- Precision farming -- Spectroradiometer -- Types of tillage
Аннотация: The paper presents a method for estimating the spatial distribution of spring barley yield, implemented based on the use of optical ground and satellite spectral data (PlanetScope with a spatial resolution of 3 meters). This approach is highly relevant for the development of precision farming technologies. Yield mapping is carried out on the basis of the data on spatial distribution of actual yield and spatial distribution of spectral optical characteristics. A feature of the method is the use of the integral values of vegetation indices (NDVI, MSAVI2, ClGreen) at various stages of crop development. Testing of the method was performed on the basis of stationary field experience, when traditional agriculture (deep plowing) was compared with resource-saving technologies (flat-cut, surface treatments and direct seeding at zero tillage). As a result, a method for estimating the spatial distribution of spring barley yield, implemented using optical ground and satellite spectral data (PlanetScope with a spatial resolution of 3 meters) was developed. The prediction of barley yields at the end of July on the basis of a linear regression model was performed, the values of the integral under the NDVI curve in different periods of time were used as parameters. The type of a multiple linear model for predicting barley with 7 variables was established (the coefficient of determination is 0.73; the root-mean-square error is 1.5). The spatial distribution of barley yield by satellite (PlanetScope) and ground data was mapped. The resulting yield maps will be used when planning work for the next year. © 2019 Space Research Institute of the Russian Academy of Sciences. All rights reserved.

Аннотация: The present study proves the presence of seasonal variability of LWRs of Arctic grayling and Siberian dace inhabiting the middle reaches of the Yenisei River. LWRs were estimated using total length (cm) and total body weight (g). The literature data on LWRs of dace and grayling from different regions were compared using log a over b plot. The comparison revealed that seasonal variability of LWRs was wider than the geographic variability for these species. The position of points on the plot can be used to predict the season of sample collection and vice versa.

Аннотация: Laboratory experiments were conducted in a hermetically sealed growth chamber with two soil samples obtained from the arctic tundra zone with different levels of moisture. Samples were maintained at a growing season typical of the region from which they were taken, and for the sample with a high level of moisture it was made twice: with the temperature in accord with natural conditions and one increased by 2 degrees C. It has been shown that heating of the overmoistened tundra soil by 2 degrees C can increased the average carbon dioxide emissions by almost two times (from 75 to 100-150 mg m(-2) h(-1)). Upon the application of heat, no significant increase in methane emission was observed.

A model study of the effect of weather forcing on the ecology of a meromictic Siberian lake / I. G. Prokopkin, E. S. Zadereev // J. Oceanology Limnology. - 2018, DOI 10.1007/s00343-018-7329-9 . - Article in press. - ISSN 2096-5508

food web -- meromictic lake -- numerical model -- sensitivity analysis -- stratification -- weather forcing
Аннотация: We used a Lake Shira numerical model to estimate the response of the ecosystem of a saline meromictic lake to variations in weather parameters during the growing season. The sensitivity analysis of the model suggests that compared to other external (nutrient inflows) and internal (spring biomasses of food-web components) factors, weather parameters are among the most influential for both mixolimnetic (phyto- and zooplankton) and monimolimnetic (purple sulfur bacteria, sulfur reducing bacteria and hydrogen sulfide) food-web components. Calculations with different weather scenarios shows how changes in the water temperature and mixing depth affect mixolimnetic and monimolimnetic food-web components and the depth of the oxic-anoxic interface in a meromictic lake. When weather forcing stimulates an increase in the biomass of food-web components in the mixolimnion, it produces cascading effects that lead to three results: 1) a higher content of detritus in the water column; 2) a higher content of hydrogen sulfide in the monimolimnion; 3) raising of the oxic-anoxic interface closer to the water-air surface. This cascading effect is complicated by the negative correlation between two light dependent primary producers located at different depths—phytoplankton in the mixolimnion and purple sulfur bacteria at the oxic-anoxic interface. Thus, weather conditions that stimulate higher phytoplankton biomass are associated with a higher detritus content and lower biomass of purple sulfur bacteria, a higher content of hydrogen sulfide and a shallower oxic-anoxic interface. The same weather conditions (higher wind, lower cloud cover, and lower air temperature) promote a scenario of less stable thermal stratification. Thus, our calculations suggest that weather parameters during the summer season strongly control the mixing depth, water temperature and the mixolimnetic food web. An effect of biogeochemical and physical interactions on the depth of the oxicanoxic interface is also detectable. However, intra- and interannual climate and weather effects will be more important for the control of meromixis stability. © 2018, Chinese Society for Oceanology and Limnology, Science Press and Springer-Verlag GmbH Germany, part of Springer Nature.

Diverse impacts of semiaquatic bird colonies on biochemical composition of seston, plankton, and fish fry in a plain reservoir / A. V. Krylov [и др.] // Zhurnal Obshchei Biol. - 2018. - Vol. 79, Is. 6. - С. 449-460, DOI 10.1134/S0044459618060052. - Cited References:47 . - ISSN 0044-4596

Аннотация: Diverse, multidirectional changes in biochemical composition of seston, plankton, and fish fry are detected in the coastal zone of a plain reservoir in the vicinity of a semiaquatic bird colony during vegetation season with extra high water level. Under these conditions, specific patterns of phyto- and zooplankton structure and quantitative characteristics, that, as was found out earlier, result from the vital activity of birds belonging to the family Ardeidae (namely, raising the share of mixotrophic phytoflagellates and copepods in plankton species composition) are leveled out. The main role in this process belongs to decomposition of immersed vegetation in the coastal zone, development of littoral macrophytes, and trophic relationships between algae and invertebrates. However, increase in atmospheric precipitation leads to increase in copepods abundance, which seems to be related to fast and intensive inflow of nitrogen-rich products of birds' vital activity. Due to this, during the whole period of observations, the following tendencies are revealed in biochemical composition of seston, plankton, and fish fry in the vicinity of the bird colony: 1) concentrations of carbon, nitrogen, and phosphorus and their ratios turn out to be auspicious for predominance of diatoms and mixotrophic phytoflagellates, rich in docosahexaenoic acid (DSA); 2) the abundance of phytoplankton, rich in polyunsaturated essential fatty acids (PEFA), favors propagation of those planktonic crustaceans which contain significantly more DSA and are more valuable food items for fish; 3) predominance of zooplankters, rich in PEFA, leads to higher concentration of PEFA in fry fish tissues, which, in certain periods, turns out to be advantageous for successful development and growth of dominant species of fish fry,such as roach, bream, white bream, and perch, by comparison with the test site.

Estimation of chlorophyll content and yield of wheat crops from reflectance spectra obtained by ground-based remote measurements / A. F. Sid'ko [et al.] // Field Crops Res. - 2017. - Vol. 207. - P24-29, DOI 10.1016/j.fcr.2016.10.023 . - ISSN 0378-4290

Chlorophyll potential -- Optical remote method -- Wheat -- Triticum aestivum
Аннотация: This study aimed to analyze the relationship between chlorophyll potential, chlorophyll content, and grain yield of different wheat cultivars by using ground remote sensing and laboratory data. Chlorophyll potential is the difference between the reflectance factor integrals with and without chlorophyll absorption (in the 550–730 nm wavelength range). Ground-truth data were obtained at the experimental fields located in the Krasnoyarsk region, Russia (2002–2012). Experiments were conducted in different seasons under various lighting conditions by controlling plants states and soil types. Spectral measurements were obtained using a double-beam spectroradiometer, which was installed on a mobile work platform at a height of 5–18 m. The photometric area varied from 0.5 to 2 m2. The study showed good correlation (R2 = 0.9) between chlorophyll potential and chlorophyll content for different wheat cultivars. However, the correlation between chlorophyll potential and grain yield was less (R2 = 0.8). The values of chlorophyll potentials depended on the type of wheat during the growing season. The novelty of the approach is that it calculates the chlorophyll potential with additional spectral regions when compared with normalized difference vegetation index. We used a spectroradiometer with high spectral resolution. This increased the accuracy and stability of measurements in rapidly changing conditions. © 2016
