Аннотация: A large number and wide variety of lake ecosystem models have been developed and published during the past four decades. We identify two challenges for making further progress in this field. One such challenge is to avoid developing more models largely following the concept of others ('reinventing the wheel'). The other challenge is to avoid focusing on only one type of model, while ignoring new and diverse approaches that have become available ('having tunnel vision'). In this paper, we aim at improving the awareness of existing models and knowledge of concurrent approaches in lake ecosystem modelling, without covering all possible model tools and avenues. First, we present a broad variety of modelling approaches. To illustrate these approaches, we give brief descriptions of rather arbitrarily selected sets of specific models. We deal with static models (steady state and regression models), complex dynamic models (CAEDYM, CE-QUAL-W2, Delft 3D-ECO, LakeMab, LakeWeb, MyLake, PCLake, PROTECH, SALMO), structurally dynamic models and minimal dynamic models. We also discuss a group of approaches that could all be classified as individual based: super-individual models (Piscator, Charisma), physiologically structured models, stage-structured models and trait-based models. We briefly mention genetic algorithms, neural networks, Kalman filters and fuzzy logic. Thereafter, we zoom in, as an in-depth example, on the multi-decadal development and application of the lake ecosystem model PCLake and related models (PCLake Metamodel, Lake Shira Model, IPH-TRIM3D-PCLake). In the discussion, we argue that while the historical development of each approach and model is understandable given its 'leading principle', there are many opportunities for combining approaches. We take the point of view that a single 'right' approach does not exist and should not be strived for. Instead, multiple modelling approaches, applied concurrently to a given problem, can help develop an integrative view on the functioning of lake ecosystems. We end with a set of specific recommendations that may be of help in the further development of lake ecosystem models. В© 2010 The Author(s).

Аннотация: The database "BiolumBase" is designed for the selection and systematization of available world information on microorganisms containing bioluminescent systems; it includes two sections: "natural" and "transgenic" luminous microorganisms. At present, logic schemes of divisions, classification of the objects, presentation of characteristics, and the inputs of relative information, as well as the necessary program modules including links to the database, are developed. The database is constructed on the basis of published data and our own experimental results; the subsequent linkage of the database to the Internet is envisaged. Users will be able to obtain not only the catalogues of strains but also information concerning the properties and functions of the known species of luminous bacteria, the structure, regulatory mechanisms, and application of bioluminescent systems and genetically engineered constructions with live genes, as well as to find references and to search strains by using any set of attributes. The database will provide information that is of interest for the development of microbial ecology and biotechnology, in particular, for the prediction of biological hazard from the application of transgenic strains.

Coupled large earthquakes in the Baikal rift system: Response to bifurcations in nonlinear resonance hysteresis / A. V. Klyuchevskii, R. G. Khlebopros // Geoscience Frontiers. - 2013, DOI 10.1016/j.gsf.2013.01.008 . - ISSN 1674-9871

Baikal rift system -- Bifurcation -- Coupled large earthquakes -- Hysteresis -- Nonlinear geodynamics -- Nonlinear oscillator with dissipation -- Phase portrait
Аннотация: The current lithospheric geodynamics and tectonophysics in the Baikal rift are discussed in terms of a nonlinear oscillator with dissipation. The nonlinear oscillator model is applicable to the area because stress change shows up as quasi-periodic inharmonic oscillations at rifting attractor structures (RAS). The model is consistent with the space-time patterns of regional seismicity in which coupled large earthquakes, proximal in time but distant in space, may be a response to bifurcations in nonlinear resonance hysteresis in a system of three oscillators corresponding to the rifting attractors. The space-time distribution of coupled MLHВ >В 5.5 events has been stable for the period of instrumental seismicity, with the largest events occurring in pairs, one shortly after another, on two ends of the rift system and with couples of smaller events in the central part of the rift. The event couples appear as peaks of earthquake 'migration' rate with an approximately decadal periodicity. Thus the energy accumulated at RAS is released in coupled large events by the mechanism of nonlinear oscillators with dissipation. The new knowledge, with special focus on space-time rifting attractors and bifurcations in a system of nonlinear resonance hysteresis, may be of theoretical and practical value for earthquake prediction issues. Extrapolation of the results into the nearest future indicates the probability of such a bifurcation in the region, i.e., there is growing risk of a pending MВ ?В 7 coupled event to happen within a few years.

Аннотация: The crystal structure of the photoprotein obelin (22.2 kDa) from Obelia longissima has been determined and refined to 1.7 Angstrom resolution. Contrary to the prediction of a peroxide, the noncovalently bound substrate, coelenterazine, has only a single oxygen atom bound at the C2-position. The protein-coelenterazine 2-oxy complex observed in the crystals is photo-active because, in the presence of calcium ion, bioluminescence emission within the crystal is observed. This structure represents only the second de novo protein structure determined using the anomalous scattering signal of the sulfur substructure in the crystal. The method used here is theoretically different from that used for crambin in 1981 (4.72 kDa) and represents a significant advancement in protein crystal structure determination.

Аннотация: The biodiversity of bacterial communities along the Yenisei River at section c. 1800 km was studied using next-generation sequencing of 16S rRNA genes and common biodiversity indices. Overall, 3022 unique operational taxonomic units were identified. Actinobacteria and Proteobacteria were the dominant phyla at all sampling sites. The highest alpha-diversity values were found in the middle section of the studied river. The beta-diversity of bacterial assemblages in the river was related to the surrounding landscape (biome): three distinctly different bacterial assemblages occurred in sections of the river, situated in mountain taiga, plain taiga and in a region of permafrost, covered by forest-tundra and tundra. Tributaries arising from these different landscapes likely contributed substantially to the variations of Yenisei bacterial communities. In contrast to a prediction of the river continuum concept, the proportion of photoautotrophic Cyanobacteria in bacterial assemblages did not increase downstream, but peaked at the middle section. © 2014 Federation of European Microbiological Societies.

Аннотация: To develop and design Life Support Systems it is necessary to evaluate their reliability. However direct experiments take much time, are very expensive, and therefore are practically impossible. Promising way is to use approximate estimates of reliability, which need essentially fewer amounts of experimental data. Two types of estimates of Life Support System reliability - additive and multiplicative ones are considered in the paper. Additive estimate is based on the assumption that total system failure probability is low and therefore it can be considered as the sum of failure probability of separate units. Additive approach allows obtaining near lower-bounded estimate of failure probability. Multiplicative estimate allows evaluating the possibility of system catastrophe due to simultaneous effect of several factors when each of them separately is not dangerous. Evaluation shows that the possible error of reliability forecast increases with the increasing of number of external factors faster than exponential function. An illustration of the ecological similarity approach as promising tool for providing estimation of full-scale system reliability by means the set of small similar experimental models.

A distribution of those sites of the length 3 among 16 viral genomes and I I bacteriophages genomes has been studied. It is shown that some tripletes with high information capacity occur in a family of relatively close genomes with the increased frequency. The molecular evolution aspects of a persistence of highly scored sites with respect to their information capacity among various genomes are discussed.

Dynamics of purple sulfur bacteria in a meromictic saline Lake Shunet (Khakassia, Siberia) in 2007–2013 / D. Y. Rogozin, V. V. Zykov, M. O. Tarnovskii // Microbiology. - 2016. - Vol. 85, Is. 1. - P93-101, DOI 10.1134/S0026261716010100 . - ISSN 0026-2617
Кл.слова (ненормированные):
long-term dynamics -- meromictic lake -- purple sulfur bacteria -- stratification
Аннотация: According to the results of seasonal monitoring, in 2007–2013 purple sulfur bacteria morphologically similar to Thiocapsa sp. Shira_1 (AJ633676 in EMBL/GenBank) predominated in the anoxygenic phototrophic community of the water column of the meromictic Lake Shira (Khakassia, Siberia). No pronounced seasonal periodicity in the total cell number in the water column was revealed during the period of observation. In some years cell number during the period when the lake was covered with ice was reliably higher than in summer. The absence of seasonal periodicity was probably due to the low amplitude of seasonal variations in temperature and illumination in the redox zone, resulting from its relatively deep location (12–16 m). The year-to-year dynamics was characterized by a reliable decrease of the total cell number in 2009–2010 and maxima in 2007 and 2011–2012. Canonical correlation analysis revealed that water temperature in the redox zone was the best predictor of the PSB abundance in Lake Shira. Water temperature, in turn, depended on the depth of mixing of the water column. Intense mixing in 2009–2011 was probably responsible for decreased PSB abundance in the lake. On the other hand, the absence of deep winter mixing, resulting in stable conditions in the chemocline, favored the preservation of relatively high PSB biomass. Prediction of circulation depth, which depends mainly on the weather conditions and dynamics of the water level, is required for prediction of PSB abundance in Lake Shira. These results may be useful for paleolimnological reconstructions of the history of the lake based on the remnants of purple sulfur bacteria in bottom sediments. © 2016, Pleiades Publishing, Ltd.

Аннотация: The structure and the first step of hydrolysis of hydrated Pu(IV) ion in aqueous medium were studied using relativistic density functional theory and the polarizable continuum model (PCM). According to calculations, the Pu(IV) ion was mainly coordinated with eight water molecules. The calculated distance Pu-O of 238-241 pm was in good agreement with the experimental value ((239 +/- 2) pm). It was demonstrated that for the correct replication of constants log K-1(0) of the first hydrolysis step, it was important to use scaling multipliers adequate to the charge of the hydrated complex when constructing the density that included the solvated complex in PCM model. The calculated values of log K-1(0) of -1.1...-0.2 were close to the experimentally defined range (-0.6-0.6). The correct replication of hydrolysis constants allowed considering the calculated range of the hydratation free energies of the Pu(IV) ion of 6070-6157 kJ/mol as a reasonable prediction of experimental values.

Estimation of the spatial distribution of spring barley yield (Krasnoyarsk Territory) from ground and satellite spectrophotometric data / I. Yu. Botvich [и др.] // Sovrem. Probl. Distancionnogo Zondirovania Zemli kosm. - 2019. - Vol. 16, Is. 5. - С. 183-193, DOI 10.21046/2070-7401-2019-16-5-183-193 . - ISSN 2070-7401

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: Calcium-regulated photoproteins are found in at least five phyla of organisms. The light emitted by those photoproteins can be tuned by mutating the photoprotein and/or by modifying the substrate coelenterazine (CTZ). Thirty years ago, Shimomura observed that the luminescence activity of aequorin was dramatically reduced when the substrate CTZ was replaced by its analogv-CTZ. The latter is formed by adding a phenyl ring to the pi-conjugated moiety of CTZ. The decrease in luminescence activity has not been understood until now. In this paper, through combined quantum mechanics and molecular mechanics calculations as well as molecular dynamics simulations, we discovered the reason for this observation. Modification of the substrate changes the conformation of nearby aromatic residues and enhances the pi-pi stacking interactions between the conjugated moiety ofv-CTZ and the residues, which weakens the charge transfer to form light emitter and leads to a lower luminescence activity. The microenvironments of CTZ in obelin and in aequorin are very similar, so we predicted that the luminescence activity of obelin will also dramatically decrease when CTZ is replaced byv-CTZ. This prediction has received strong evidence from currently theoretical calculations and has been verified by experiments.

Lake Uchum -- bacterial community -- meromictic lake -- purple sulfur bacteria
Аннотация: Lake Uchum is a newly defined meromictic lake in Siberia with clear seasonal changes in its mixolimnion. This study characterized the temporal dynamics and vertical profile of bacterial communities in oxic and anoxic zones of the lake across all four seasons: October (autumn), March (winter), May (spring), and August (summer). Bacterial richness and diversity in the anoxic zone varied widely between time points.Proteobacteriawas the dominant bacterial phylum throughout the oxic and anoxic zones across all four seasons.Alphaproteobacteria(Loktanella) andGammaproteobacteria(Aliidiomarina) exhibited the highest abundance in the oxic and anoxic zone, respectively. Furthermore, there was a successional shift in sulfate-reducing bacteria (SRB) and sulfur-oxidizing bacteria in the anoxic zone across the seasons. The most dominant SRB,Desulfonatronovibriosp., is likely one of the main producers of hydrogen sulfide (H2S) and typically accumulates the most H2S in winter. The representative anoxygenic phototrophic bacterial group in Lake Uchum was purple sulfur bacteria (PSB). PSB were dominant (60.76%) in summer, but only had 0.2-1.5% relative abundance from autumn to spring. Multivariate analysis revealed that the abundance of these SRB and PSB correlated to the concentration of H2S in Lake Uchum. Taken together, this study provides insights into the relationships between changes in bacterial community and environmental features in Lake Uchum.

Аннотация: There is a need for rapid simple and informative environmental assessment methods. The present investigation is aimed at assessing the possibility of using the combined enzyme system of luminescent bacteria: NAD(P)H:FMN-oxidoreductase + luciferase (Red + Luc) for predicting the potential toxicity of industrial urbostratozems sampled in the city of Krasnoyarsk. Three groups of urbostratozems polluted with fluorine, arsenic and lead, were tested by the methods of chemical analysis and enzymatic bioassay. Only the assessment of the arsenic-contaminated soil samples showed the dependence between the reduced activity of the enzyme system and the arsenic concentration variations. The results reveal that the sensitivity of the Red + Luc enzyme system to the soil pollutants depends on the properties of the studied soil samples. Moreover, the solubility of lead in the soil samples affects the accuracy of the enzymatic bioassays for soil toxicity testing. The results of the enzymatic bioassay of the fluoride-contaminated soil samples are ambiguous. The obtained data show the relevance of the sample preparation during integral bioassays. In addition, soil properties should be taken into account as well. The current study emphasizes the importance of conducting chemical and biological testing as a combined set to obtain comprehensive information about the anthropogenic load. © 2021 Elsevier B.V.
