Аннотация: Zooplankton carcasses are ubiquitous in marine and freshwater systems, implicating the importance of non-predatory mortality, but both are often overlooked in ecological studies compared with predatory mortality. The development of several microscopic methods allows the distinction between live and dead zooplankton in field samples, and the reported percentages of dead zooplankton average 11.6 (minimum) to 59.8 (maximum) in marine environments, and 7.4 (minimum) to 47.6 (maximum) in fresh and inland waters. Common causes of non-predatory mortality among zooplankton include senescence, temperature change, physical and chemical stresses, parasitism and food-related factors. Carcasses resulting from non-predatory mortality may undergo decomposition leading to an increase in microbial production and a shift in microbial composition in the water column. Alternatively, sinking carcasses may contribute significantly to vertical carbon flux especially outside the phytoplankton growth seasons, and become a food source for the benthos. Global climate change is already altering freshwater ecosystems on multiple levels, and likely will have significant positive or negative effects on zooplankton non-predatory mortality. Better spatial and temporal studies of zooplankton carcasses and non-predatory mortality rates will improve our understanding of this important but under-appreciated topic.

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.

Volatile metabolites of higher plant crops as a photosynthesizing life support system component under temperature stress at different light intensities / I. I. Gitelson [et al.] // Advances in Space Research. - 2003. - Vol. 31, Is. 7. - P1781-1786, DOI 10.1016/S0273-1177(03)00121-2 . - ISSN 0273-1177

Аннотация: The effect of elevated temperatures of 35 and 45В°C (at the intensities of photosynthetically active radiation 322, 690 and 1104 ?mol-m-2-s-1) on the photosynthesis, respiration, and qualitative and quantitative composition of the volatiles emitted by wheat (Triticum aestuvi L., cultivar 232) crops was investigated in growth chambers. Identification and quantification of more than 20 volatile compounds (terpenoids - ?-pinene, ?3 carene, limonene, benzene, ?-and transcaryophyllene, ?- and ?-terpinene, their derivatives, aromatic hydrocarbons, etc.) were conducted by gas chromatograph/mass spectrometry. Under light intensity of 1104 ?mol-m-2-s-1, heat resistance of photosynthesis and respiration increased at 35В°C and decreased at 45В°C. The action of elevated temperatures brought about variations in the rate and direction of the synthesis of volatile metabolites. The emission of volatile compounds was the greatest under a reduced irradiation of 322 ?mol-m-2-s-1 and the smallest under 1104 ?mol-m-2-s-1 at 35В°C. During the repair period, the contents and proportions of volatile compounds were different from their initial values, too. The degree of disruption and the following recovery of the functional state depended on the light intensity during the exposure to elevated temperatures. The investigation of the atmosphere of the growth chamber without plants has revaled the substances that were definitely technogenic in origin: tetramethylurea, dimethylsulfide, dibutylsulfide, dibutylphthalate, and a number of components of furan and silane nature.

Аннотация: The effects of elevated temperature (35 and 45degreesC) on photosynthesis, respiration, and both the qualitative and quantitative compositions of volatile emissions (VE) of wheat (Triticum aestuvum L. cultivar 232) cenoses at light intensities of 70, 150, or 240 W/m(2) of photosynthetically available radiation (PAR) were studied. At a PAR of 240 W/m(2), the thermal stabilities of photosynthesis and respiration increased at 35degreesC and decreased at 45degreesC. Elevated temperatures nonuniformly changed the rates and direction of VE syntheses. In this process, the highest increase in VE evolution was observed at 70 W/m(2) and 35degreesC; the lowest, at 240 W/m(2). In addition, the concentrations and composition of VE during the repair period differed from the initial values.

Variability of fluorescence spectra of coelenteramide-containing proteins as a basis for toxicity monitoring / R. R. Alieva, N. S. Kudryasheva // Talanta. - 2017. - Vol. 170. - P425-431, DOI 10.1016/j.talanta.2017.04.043 . - ISSN 0039-9140

Аннотация: Nowadays, physicochemical approach to understanding toxic effects remains underdeveloped. A proper development of such mode would be concerned with simplest bioassay systems. Coelenteramide-Containing Fluorescent Proteins (CLM-CFPs) can serve as proper tools for study primary physicochemical processes in organisms under external exposures. CLM-CFPs are products of bioluminescent reactions of marine coelenterates. As opposed to Green Fluorescent Proteins, the CLM-CFPs are not widely applied in biomedical research, and their potential as colored biomarkers is undervalued now. Coelenteramide, fluorophore of CLM-CFPs, is a photochemically active molecule; it acts as a proton donor in its electron-excited states, generating several forms of different fluorescent state energy and, hence, different fluorescence color, from violet to green. Contributions of the forms to the visible fluorescence depend on the coelenteramide microenvironment in proteins. Hence, CLM-CFPs can serve as fluorescence biomarkers with color differentiation to monitor results of destructive biomolecule exposures. The paper reviews experimental and theoretical studies of spectral-luminescent and photochemical properties of CLM-CFPs, as well as their variation under different exposures – chemicals, temperature, and ionizing radiation. Application of CLM-CFPs as toxicity bioassays of a new type is justified. © 2017

Cold and hot extracts -- culture liquid -- enzymatic system -- hispidin -- luminous fungi -- substrate of luminescent reaction
Аннотация: The luminescent response of the enzymatic system of Armillaria borealis on the cold and hot extracts from cell-free culture liquids of Inonotus obliquus, Pholiota sp. and A. borealis was examined. The greatest influence on the light emission produced by the luminescent system of A. borealis was provided by the temperature at which the probes were prepared for assay. Boiling a culture liquid on water bath for a few minutes promoted a multifold increase in the luminescence. The results of luminescence assay suggest that the substance involved in the bioluminescent reaction in higher fungi is presented in culture liquids and mycelia in two forms. In one form, it is ready to interact with the enzymatic system and in the second form, it becomes accessible for the reaction after heat treatment. The pool of thermoactivated substance was found to be much large than the amount of the ready accessible one. We suggest that predecessors of hispidin, which is fungal luciferin precursor, are responsible for this phenomenon. They are not involved in bioluminescence at their original state and are converted into the substrate under the influence of high temperature. © 2019, © 2019 The Author(s).

Аннотация: The paper describes the fields of transformation of soil and land resources of the Middle Siberia as the result of long-term climatic changes. The description of soil and land resources is given. The climatic changes have been evaluated for the period from 1919 to 2018, and increase of the annual mean air temperature and amount of precipitation in natural zones of the region has been established on the basis of the analysis of linear trends. Under the impact of these factors, shifting of zone borders occurs, which leads to replacement of the soil cover structure at the species, generic and subtype levels. Changing regimes and soil properties cause the necessity to use new sorts and adapted technologies for crop growing. © 2019 IOP Publishing Ltd. All rights reserved.

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.

Tolerance of wheat and lettuce plants grown on human mineralized waste to high temperature stress / S. A. Ushakova [et al.] // Advances in Space Research. - 2013. - Vol. 51, Is. 11. - P2075-2083, DOI 10.1016/j.asr.2013.01.017 . - ISSN 0273-1177

Аннотация: The main objective of a life support system for space missions is to supply a crew with food, water and oxygen, and to eliminate their wastes. The ultimate goal is to achieve the highest degree of closure of the system using controlled processes offering a high level of reliability and flexibility. Enhancement of closure of a biological life support system (BLSS) that includes plants relies on increased regeneration of plant waste, and utilization of solid and liquid human wastes. Clearly, the robustness of a BLSS subjected to stress will be substantially determined by the robustness of the plant components of the phototrophic unit. The aim of the present work was to estimate the heat resistance of two plants (wheat and lettuce) grown on human wastes. Human exometabolites mineralized by hydrogen peroxide in an electromagnetic field were used to make a nutrient solution for the plants. We looked for a possible increase in the heat tolerance of the wheat plants using changes in photosynthetically active radiation (PAR) intensity during heat stress. At age 15 days, plants were subjected to a rise in air temperature (from 23 В± 1 В°C to 44 В± 1 В°) under different PAR intensities for 4 h. The status of the photosynthetic apparatus of the plants was assessed by external 2 gas exchange and fluorescence measurements. The increased irradiance of the plants during the high temperature period demonstrated its protective action for both the photosynthetic apparatus of the leaves and subsequent plant growth and development. The productivity of the plants subjected to temperature changes at 250 W m-2 of PAR did not differ from that of controls, whereas the productivity of the plants subjected to the same heat stress but in darkness was halved.

Аннотация: The main objective of an LSS is to supply a crew with food, water and oxygen, and to eliminate its waste. The ultimate goal is to achieve the highest degree of closure of the system using controlled processes offering a high level of reliability and flexibility. Enhancement of closedness of biological life support systems (BLSS) including plants relies on increased regeneration of gas, water and plant waste, and utilization of solid and liquid human wastes. Clearly, the robustness of an LSS subjected to stress will be substantially determined by the robustness of the plant components of the phototrophic unit. The aim of the present work was to estimate the heat resistance of plants grown on human wastes. Human exometabolites mineralized by hydrogen peroxide in an alternating electromagnetic field were used to make a nutrient solution for the plants. We looked for a possible increase in the heat resistance of the plants using changes in photosynthetically active radiation (PAR) intensity during heat stress. At ages 15 and 25 days, plants were subjected to a rise in air temperature (from 22-24В°C to 44В°C) under different PAR intensities for 4 hours. The status of the photosynthetic apparatus of the plants was assessed by external CO2 gas exchange and fluorescence measurements. The increased irradiance of the plants during the high temperature period demonstrated its protective action for both the photosynthetic apparatus of the leaves and subsequent plant growth and development. The productivity of the plants subjected to temperature changes at 250 W/m2 of PAR did not differ from that of controls, whereas the productivity of the plants subjected to the same heat stress but in darkness was halved. The heat resistance of the reproductive organs of 25-day-old plants was significantly lower than that of 15-day-old plants subjected to similar light and temperature conditions.

Tolerance of LSS plant component to elevated temperatures / S. A. Ushakova, A. A. Tikhomirov // Acta Astronautica. - 2002. - Vol. 50, Is. 12. - P759-764, DOI 10.1016/S0094-5765(02)00010-3 . - ISSN 0094-5765

Аннотация: Stability of LSS based on biological regeneration of water, air and food subject to damaging factors is largely dependent on the behavior of the photosynthesizing component represented, mainly, by higher plants. The purpose of this study is to evaluate the tolerance of uneven-aged wheat and radish cenoses to temperature effects different in time and value. Estimation of thermal tolerance of plants demonstrated that exposure for 20 h to the temperature increasing to 45В°C brought about irreversible damage both in photosynthetic processes (up to 80% of initial value) and the processes of growth and development. Kinetics of visible photosynthesis during exposure to elevated temperatures can be used to evaluate critical exposure time within the range of which the damage of metabolic processes is reversible. With varying light intensity and air temperature it is possible to find a time period admissible for the plants to stay under adverse conditions without considerable damage of metabolic processes.

Time-space structure and variability of surface temperature frontal zones in the ocean (based on AVHRR satellite data) / A. V. Kartushinsky // Advances in Space Research. - 2000. - Vol. 25, Is. 5. - P1107-1110, DOI 10.1016/S0273-1177(99)00871-6 . - ISSN 0273-1177

Аннотация: Satellite monitoring of large-scale ocean fields allows collection and analyse of information on dynamics processes in various areas of the ocean. Investigation of the World Ocean processes involves the determination of space-time changes of sea surface temperature (SST). Water temperature of the ocean is one of major characteristics of surface water masses. Distribution of water temperature depends not only on regional climate peculiarities but also on formation of high gradient temperature zones. These zones emerge due to interaction of different current structure, circulation and eddies. Some more important characteristics of such zones are space dimensions and time of existence (lifetime). Space-time scales of the above structure have not been investigated in detail. The aim of the paper is to study space-time changes of the surface temperature frontal zones and frontal partitions in the ocean by AVHRR satellite information.

Аннотация: The age-related changes in the temperature dependence curves (TDC) of chlorophyll fluorescence were studied in leaf segments of wheat (Triticum aestivum L.), tomato (Lycopersicum esculentum Mill.), and cucumber (Cucumis sativum L.) plants grown under controlled photoculture conditions. Three major TDC patterns of chlorophyll fluorescence were identified within the temperature range of 25-70В°C, with each of the patterns corresponding to a certain phase of leaf development. The transition from one type of thermogram to another was a gradual and ordered process. The magnitude of the low-temperature TDC peak increased until leaves completely expanded and declined with leaf senescence. In the course of leaf senescence, the thermograms exhibited an additional shoulder, which further changed into a peak at 55-65В°C with increasing magnitude. Our data provide the basis for assessing leaf age from the type of chlorophyll fluorescence thermogram and the changes in the particular indices characteristic of TDC of chlorophyll fluorescence.

Аннотация: The thermal conductivity, k, of diamond/carbon composites with different ratios of sp(2)/sp(3)-bonded carbon is measured by the laser flash technique. The thermal conductivity of nanocomposites containing 6 nm diamond particles falls within the range of k = 0.003-0.017 W/cmK; at room temperature. The thermal conductivity increases while nanopores are gradually filled with pyrolytic carbon (pyrocarbon/diamond mass ratio variation of 0.0-0.5). Transmission electron microscopy data reveal a fairly uniform mixture of two carbon phases, the diamond and matrix having similar grain sizes. Estimates show that the phonon free path is limited by dimensions of carbon matrix layer. Thermal data for coarse-grain (1-2 mu m) composites are also given for comparison.
