Аннотация: There is considerable data on molecular evolution, but there remains no approach to systematizing them within the framework of the key problems of biology. To search for the most common properties of evolving systems, the heuristic method has been proposed. Artificial networks of formal neurons were chosen as the heuristic model object. The paper examines the divergent component of evolutionary trajectory formation. As a result of the simulation, the dependence of the potential variability parameter on the position of the fitness function landscape was obtained. The simulation results are in agreement with the real data of molecular evolution experiments.

Аннотация: The problem of how a gradual development of ecological and morphological adaptations combines with large genome rearrangements, which have been found to occur in the phylogeny of many groups of organisms, is a matter of discussion in the literature. The objective of this work was to study the problem with the example of salmonids, whose evolution included at least six events of multiple chromosome fusions. Large karyotype rearrangements are associated with a decrease in ecological and morphological diversity in salmonids. In the above example, genome rearrangements seem to distort the function of the genetic systems that are responsible for the occurrence of certain ecological forms in salmonids. © 2017 by the authors; Licensee MDPI, Basel, Switzerland.

Аннотация: This paper is an introduction to a special issue of the journal. A brief historical delineation of the question of studying interfaces between adjacent ecosystems (ecotones) is presented. High biodiversity of ecotones and their vulnerability to natural and anthropogenic impacts, including invasions of alien species, are noted. It is supposed that there is no contradiction between the ecotone and river continuum concepts. The important ecological role of amphibiotic animals and plants in interactions and functioning of the adjacent ecosystems is emphasized. The issue of studying the quantitative parameters of fluxes of matter and energy between ecosystems in conjunction with their qualitative parameters (chemical elemental and biochemical compositions) is considered in the present paper. © 2016, Pleiades Publishing, Ltd.

Comparative analysis of the evolution of Eigen hypercycles and populations of microorganisms in open systems / N. S. Pechurkin, N. V. Nikiforova, A. G. Degermendzhi // Biophysics. - 1982. - Vol. 27, Is. 2. - P304-311 . - ISSN 0006-3509
Аннотация: Models of the evolution of Eigen's hypercycles and microbial flow populations are compared. It is shown that these model descriptions of microevolution completely agree in the case of maintenance of constant organization. In the case of constant flows in the Eigen model it is necessary to make additional allowance for the dynamics of the concentrations of the energy monomers. The results of the experiments on the micro-evolution of microbes in these and other conditions are presented. В© 1982.

Аннотация: Seasonal dynamics of contents of essential polyunsaturated fatty acids (PUFA) in dominant groups of benthic invertebrates: gammarids (Gammaridae, Amphipoda), oligochaetes (Oligochaeta), chironomid larvae (Chironomidae, Diptera) and caddisfly larvae (Trichoptera), and dominant benthivorous fish, Siberian grayling Thymallus arcticus, have been studied in ecosystem of the large Siberian river. During the year of the study most benthic invertebrate taxa showed significant variations in the contents of both C-18 and long chain C-20-22 PUFAs. In contrast, the fish, which consumed the zoobenthos, had no significant seasonal variations in long chain PUFAs' contents. Thereby, the fish, as organisms of relatively higher evolution level than invertebrates, was supposed to have more strict metabolic control of long chain PUFAs' contents. Evidence was obtained that the studied fish species, grayling, may be capable to convert dietary EPA into DHA. В© 2006 Elsevier Inc. All rights reserved.

Аннотация: The process of biotic turnover in a closed ecological system (CES) with an external energy flow was analyzed by mathematical modeling of the biotic cycle formation. The formation of hierarchical structure in model CESs is governed by energy criteria. Energy flow through the ecosystem increases when a predator is introduced into a "producer-reducer" system at steady state. Analysis of the model shows that under certain conditions the presence of the primary predator with its high mineralization ability accelerates the biotic turnover measured by primary production. We, therefore, conclude that for every system it is possible to find a suitable predator able to provide the system with a higher biotic turnover rate and energy consumption. В© 2001 COSPAR.

Direct and indirect impacts of fish on crustacean zooplankton in experimental mesocosms / I. Feniova [et al.] // Water. - 2019. - Vol. 11, Is. 10. - Ст. 2090, DOI 10.3390/w11102090 . - ISSN 2073-4441

Аннотация: Understanding the factors that regulate phytoplankton and zooplankton is an important goal of aquatic ecologists; however, much remains unknown because of complex interactions between phytoplankton, zooplankton, and fish. Zooplankton, in particular cladocerans, can be regulated by bottom-up factors either via food quantity or food quality in terms of polyunsaturated fatty acids (PUFA) or phosphorus (P) contents in phytoplankton. Fish can recycle nutrients and in turn change the PUFA and P contents of algal resources, thus modifying bottom-up regulation. Furthermore, fish can change phytoplankton structure through consumption of cladocerans which selectively graze phytoplankton. We conducted a mesocosm (300 L) experiment to determine how trophic state and fish affected crustacean dynamics. The mesocosms were filled with water containing natural plankton from the eutrophic Lake Jorzec and mesotrophic Lake Majcz (Northeastern Poland), and we manipulated fish presence/absence. We also conducted a complementary life-table experiment to determine how trophic state and fish nonconsumptively affected demographic parameters of the dominant cladocerans in the mesocosms. Small and large cladoceran species responded differently to food quantity and quality. Small-bodied Ceriodaphnia were regulated mainly by resource concentrations (i.e., food quantity), while large species were limited by PUFAs (i.e., food quality). Fish likely increased food quality in terms of PUFA, primarily eicosapentaenoic acids (EPA), thus providing conditions for more successful development of Daphnia than in the fish-free treatments. Phosphorus in the seston was likely limiting for zooplankton. However, food quality in terms of phosphorus was likely less important than PUFA because zooplankton can accumulate nutrients in their body. © 2019 by the authors.

Effect of way of cooking on content of essential polyunsaturated fatty acids in muscle tissue of humpback salmon (Oncorhynchus gorbuscha) / M. I. Gladyshev [et al.] // Food Chemistry. - 2006. - Vol. 96, Is. 3. - P446-451, DOI 10.1016/j.foodchem.2005.02.034 . - ISSN 0308-8146

Аннотация: Contents of fatty acids in filets of unfrozen (control), boiled, fried, roasted and boiled in a small amount of water humpback salmon, collected from a wholesale market in Krasnoyarsk city (Siberia, Russia) were analyzed. Special attention was paid to essential polyunsaturated fatty acids of ?3 family: eicosapentaenoic, 20:5?3 (EPA) and docosahexaenoic, 22:6?3 (DHA). Heat treatment in general did not decrease content of EPA and DHA in humpback, except a modest reduction during frying. Cooked humpback appeared to be the valuable source of essential ?3 PUFAs, namely EPA and DHA. It was hypothesized that the absence of significant reduction of PUFAs' contents in red flesh of fishes of Salmonidae family during heat treatment may be due to a high level of natural antioxidants which formed in the course of evolution as adaptation to their ecological niche.

Effects of zebra mussels on cladoceran communities under eutrophic conditions / I. Feniova [et al.] // Hydrobiologia. - 2018. - P1-18, DOI 10.1007/s10750-018-3699-4 . - ISSN 0018-8158

Аннотация: The purpose of this study was to determine how zebra mussels affected cladoceran community structure under eutrophic conditions. We conducted a mesocosm study where we manipulated the presence of zebra mussels and the presence of large-bodied Daphnia (Daphnia magna and Daphnia pulicaria). We also conducted a complimentary life-table experiment to determine how water from the zebra mussel treatment affected the life history characteristics of the cladoceran species. We anticipated that small- and large-bodied cladoceran species would respond differently to changes in algal quality and quantity under the effects of zebra mussels. Large-bodied Daphnia successfully established in the zebra mussel treatment but failed to grow in the control. We did not observe positive relationships between food concentrations and cladoceran abundances. However, the phosphorus content in the seston indicated that food quality was below the threshold level for large-bodied cladocerans at the beginning of the experiment. We believe that zebra mussels quickly enhanced the phosphorus content in the seston due to the excretion of inorganic phosphorus, thus facilitating the development of large-bodied Daphnia. In conclusion, our results suggest that zebra mussels can alter the phosphorus content of seston in lakes and this can affect the dynamics of crustacean zooplankton. © 2018 Springer International Publishing AG, part of Springer Nature

Efficiency of Transfer of Essential Substances from Phytoplankton to Planktonic Crustaceans in Mesotrophic Conditions / I. Y. Feniova, E. G. Sakharova, Z. F. Buseva [et al.] // Inland Water Biol. - 2021. - Vol. 14, Is. 1. - P49-59, DOI 10.1134/S1995082920040033 . - ISSN 1995-0829

Аннотация: Abstract: We assessed the efficiency of the transfer of essential substances (carbon, phosphorus, nitrogen, and fatty acids (FA), including polyunsaturated fatty acids (PUFAs)) from phytoplankton to planktonic crustaceans in experimental mesocosms in the presence and absence of fish. The experiments were conducted under mesotrophic conditions in 300 L mesocosms. We have found that transfer efficiencies from producers to consumers are different for different substances. In particular, FA, including PUFAs, are transferred less efficiently than carbon. In contrast, the efficiency of nutrient transfer, especially phosphorus, is higher than that of carbon. This evidences that zooplankton can accumulate nutrients, increasing their quality as a resource for higher trophic levels. Fish significantly reduced the efficiency of carbon transfer from phytoplankton to zooplankton per unit of water volume, but did not affect the transfer of substances per unit of biomass. Thus, the quality of zooplankton as a food resource for higher trophic levels did not decrease in the presence of fish, despite the decline in the efficiency of the transfer of the essential substances per unit of water volume under their influence. Since the efficiency of essential substances transfered from phytoplankton to zooplankton determines the functioning of the entire trophic web, we should seek ways to increase it. © 2021, Pleiades Publishing, Ltd.

Аннотация: The question on the essence of life as phenomenon is the key one for astrobiology, since the answer to this question determines "breadth of our outlook". Taking Earth's version of life as the pattern extremely under-estimates our estimation of the probability of life origin and respectively expected probability of extraterrestrial life discovery. In the paper the hypothetical key attribute of life in general is selected on the base of comparative analyses and deductive inference. Simulation conducted on the base of neural network model shows that the same function could be realized by means of great variety of structures, which originated in the course of an evolutionary process. So multiplicity of evolutionary outcomes essentially increases the probability of final result - realization of an integrated function providing fitness to environment. Life as the integrated function can be realized via great variety of development ways and structures. A logical consequence of definitions for life as phenomenon is suggested. Final one is "Life is specific organization of informational and energetic processes coupling, enabling choice-making, and displayed as anomalies of different kinds". Anomalies of visible form, mechanical movement, chemical composition and noticeable response are considered. Presented in the paper sweeping generalization is not rigorously proven, however it can play heuristic role in increasing the level of specificity of searching for extraterrestrial life.

Аннотация: The use of relative variable fluorescence (RVF) of chlorophyll, as measured in the presence of Diuron, an inhibitor of electron transfer, for the estimation of the photosynthetic activity of plankton microalgae was analyzed under a wide range of light intensities in the PAR region. Oxygen evolution rates (estimated by the method of light and dark bottles and the amperometric method), RVF, and chlorophyll a concentration were measured in parallel in natural algal cenoses and microecosystems. When the previously used regression equation, in the form A = b(DeltaF/F-d)CchlI, where A is O-2 evolution rate (g/(m(3) h), DeltaF/F-d is RVF (relative units), C-chl is chlorophyll a concentration (mg/m(3)), and I is light intensity (W/m(2)), was verified in the PAR region, we observed a nonlinear dependence of the correction coefficient b on I, which can be described by the formula b = 6.227 x 10(3)rootI. This result agrees with the hypothesis that chlorophyll a fluorescence quenching comprises photochemical (qQ) and energy (qE) components. On the basis of the energy model, we determined the upper limit b(max) = 0.003 for light intensity range I < 4.4 W/m(2) and the lower limit b(min) = 0.0003 for I = 400 W/m(2).

Аннотация: Closed ecological systems are of two-fold interest - as models of the Earth's biosphere explorable in experiments and as a facility for long-term autonomous human life support beyond the Earth. Theoretical analysis and experimental implementation of highly closed manned systems has been the subject of studies at the Institute of Biophysics (Russian Academy of Sciences, Siberian Branch) for many years. BIOS systems of increasing complexity with complete regeneration of atmosphere, water and partially food have been realized. In BIOS-3 experiments the system inhabited by 2-3 researchers for 4-6 months maintained its metabolic equilibrium without any negative physiological effect on the crew, which proves its sustainable condition. Specific for BIOS-3 is internal control by the people inhabiting the system. So, BIOS-3 is the first experimental implementation of V.l. Vernadsky's idea about the noosphere - habitable Biosphere controlled by human intelligence. Contrary to predictions of many environmentalists the closedness of the ecosystem is a factor that does not reduce, but increases its sustainability and makes its use for reliable life support outside the Earth realistic. The system is sustainable owing to permanent feedback between the monitoring of few key parameters of the system and automatic corrective actions on them. Main object of control is photo-biosynthesis regenerating parameters of human habitat disturbed by his vital activities. This principle has been realized in BIOS system and proved its reliability in long-term experiments. A new challenge is specified-optimal increase of trophic closedness of the system by reproduction within it essential proteins (peptides and amino acids), lipids, vitamins and other essential compounds. Alternative lines of attack on this problem by state-of-the-art biotechnological methods, GMO including, are under analysis. Reduced BIOS version - without complete closure - can be a breakthrough instrument to improve the quality of life of people living under extreme conditions on the Earth - in polar latitudes (Arctic, Antarctic), in deserts, in high mountains.

Fatty acid composition of fish species with different feeding habits from an Arctic Lake / M. I. Gladyshev [et al.] // Doklad. Biochem. Biophys. - 2017. - Vol. 474, Is. 1. - P220-223, DOI 10.1134/S1607672917030164 . - ISSN 1607-6729
Аннотация: We compared the composition and content of fatty acids (FAs) in fish with different feeding habits (sardine (least) cisco Coregonus sardinella, goggle-eyed charr (pucheglazka) form of Salvelinus alpinus complex, humpback whitefish Coregonus pidschian, broad whitefish Coregonus nasus, boganid charr Salvelinus boganidae, and northern pike Esox lucius from an Arctic Lake. Feeding habits of the studied fish (planktivore, benthivore, or piscivore) significantly affected the composition of biomarker fatty acids and the ratio of stable isotopes of carbon and nitrogen in their biomass. The hypothesis on a higher content of eicosapentaenoic and docosahexaenoic acids in the fish of higher trophic level (piscivores) when compared within the same taxonomic group (order Salmoniformes) was confirmed. © 2017, Pleiades Publishing, Ltd.

Аннотация: In luminous bacteria NAD(P)H:flavin-oxidoreductases LuxG and Fre, there are homologous enzymes that could provide a luciferase with reduced flavin. Although Fre functions as a housekeeping enzyme, LuxG appears to be a source of reduced flavin for bioluminescence as it is transcribed together with luciferase. This study is aimed at providing the basic conception of Fre and LuxG evolution and revealing the peculiarities of the active site structure resulted from a functional variation within the oxidoreductase family. A phylogenetic analysis has demonstrated that Fre and LuxG oxidoreductases have evolved separately after the gene duplication event, and consequently, they have acquired changes in the conservation of functionally related sites. Namely, different evolutionary rates have been observed at the site responsible for specificity to flavin substrate (Arg 46). Also, Tyr 72 forming a part of a mobile loop involved in FAD binding has been found to be conserved among Fre in contrast to LuxG oxidoreductases. The conservation of different amino acid types in NAD(P)H binding site has been defined for Fre (arginine) and LuxG (proline) oxidoreductases.

Bioluminescence -- Fungal luciferase -- Fungal luciferin biosynthesis
Аннотация: Bioluminescence is found across the entire tree of life, conferring a spectacular set of visually oriented functions from attracting mates to scaring off predators. Half a dozen different luciferins, molecules that emit light when enzymatically oxidized, are known. However, just one biochemical pathway for luciferin biosynthesis has been described in full, which is found only in bacteria. Here, we report identification of the fungal luciferase and three other key enzymes that together form the biosynthetic cycle of the fungal luciferin from caffeic acid, a simple and widespread metabolite. Introduction of the identified genes into the genome of the yeast Pichia pastoris along with caffeic acid biosynthesis genes resulted in a strain that is autoluminescent in standard media. We analyzed evolution of the enzymes of the luciferin biosynthesis cycle and found that fungal bioluminescence emerged through a series of events that included two independent gene duplications. The retention of the duplicated enzymes of the luciferin pathway in nonluminescent fungi shows that the gene duplication was followed by functional sequence divergence of enzymes of at least one gene in the biosynthetic pathway and suggests that the evolution of fungal bioluminescence proceeded through several closely related stepping stone nonluminescent biochemical reactions with adaptive roles. The availability of a complete eukaryotic luciferin biosynthesis pathway provides several applications in biomedicine and bioengineering. © 2018 National Academy of Sciences. All Rights Reserved.

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).

Influence of biota on global climate / D. A. Semenov, R. G. Khlebopros // Biophysics. - 2005. - Vol. 50, Is. 4. - P659-662 . - ISSN 0006-3509
Кл.слова (ненормированные):
Biosphere -- Climate -- CO2 balance -- Energy balance -- Modeling
Аннотация: A model consisting of two blocks (equations) is proposed for the analytical study of the biosphere-climate system over great periods of time. The first equation describes the balance of carbon dioxide in the atmosphere and represents the biological block of the model. The second equation is the equation of energy balance or the physical block of the system. The model is based on the most general concepts of living matter and the evolution process. A possible interpretation of some events and phenomena in the Earth history is given in terms of the model. Copyright В© 2005 by MAIK "Nauka/ Interperiodica".
