Intraspecies variability of fatty acid content and composition of a cosmopolitan benthic invertebrate, Gammarus lacustris / O. N. Makhutova [et al.] // Inland Waters. - 2018. - Vol. 8, Is. 3. - P356-367, DOI 10.1080/20442041.2018.1487157 . - ISSN 2044-2041

essential polyunsaturated fatty acids -- fish -- food quality -- salinity -- temperature
Аннотация: Aquatic invertebrates are valuable dietary sources of essential polyunsaturated fatty acids, eicosapentaenoic acid (EPA, 20:5n-3) and docosahexaenoic acid (DHA, 22:6n-3), for fish. Phylogeny, diet, and various ecological factors affect the fatty acid composition of aquatic invertebrates. We focused our study on the effect of ecological factors to a cosmopolitan species inhabiting lakes that differed in salinity, temperature, and presence/absence of predators (fish). To avoid the effect of phylogeny, which strongly influences the fatty acid composition of animals, we studied several populations of one cosmopolitan benthic species, Gammarus lacustris Sars. We found that differences in fatty acid percentages of G. lacustris were mainly affected by differences in their diets. Some populations preferred dinoflagellates, cryptophytes, green algae/cyanobacteria, and bacteria; other populations selected diatoms; and still other populations consumed zooplankton or allochthonous (terrestrial) organic matter. The salinity and presence/absence of fish affected the contents of EPA and DHA in G. lacustris. Populations from saline and fishless lakes had significantly higher contents of EPA and DHA. Thus, stocking of fishless lakes dominated by G. lacustris with fish could lead to a decrease in EPA and DHA contents in the gammarids. We propose that some saline and fishless lakes could be used as a source of gammarids for aquaculture fish feeding. © 2018, © 2018 International Society of Limnology (SIL).

agricultural crops -- phenology -- satellite data -- woody vegetation
Аннотация: The patterns of the phase portraits of vegetation (agrophytocenosis, woody vegetation) constructed using two-dimensional space radiation temperature values and Normalized Difference Vegetation Index were studied. An analysis of the phenological variability of vegetation in the south of the Krasnoyarsk Territory and the Republic of Khakassia during the growing seasons of 2003 and 2006 was carried out. Distinctive features of the phase portraits of agrophytocenosis and woody vegetation were revealed. The possibility of determining the boundaries of phenological states in the phytocenosis, and the transition range from one state into another was shown. Based on the complex analysis of the reflexive and radiative properties of the plant samples, an algorithm for calculating the start and end of the growing season was developed. © 2017, Pleiades Publishing, Inc.

Fatty acid composition and content in chironomid species at various life stages dominating in a saline Siberian lake / O. N. Makhutova [et al.] // Contemp. Probl. Ecol. - 2017. - Vol. 10, Is. 3. - P230-239, DOI 10.1134/S1995425517030064 . - ISSN 1995-4255

amphibiotic insect emergence -- Chironomidae -- fatty acids -- life stages -- saline lake -- Chironomidae -- Glyptotendipes barbipes -- Hexapoda
Аннотация: This paper studies the fatty acid (FA) composition and content of essential polyunsaturated fatty acids (PUFAs) in the biomass of larvae and adults of chironomids from the saline Shira Lake. Species of different genera significantly differ in their larvae FA composition and essential PUFA content, and they also occupy different ecological niches: Chironomus species with a low PUFA content (0.2–0.3 mg g–1 of wet weight) inhabit a deepwater zone of the lake, while Glyptotendipes barbipes species that were richer in PUFA (2.3 mg g–1 of wet weight) dwell in the littoral of the lake. The biochemical differences are likely related to different feeding spectra of these taxa and can also be explained by the phylogenetic factor. A comparison does not find differences in the PUFA content in larvae and adults in the samples of the same species G. barbipes; i.e., we do not confirm the data on an increase in the content of these acids during the metamorphosis of chironomids. Thus, the data on the PUFA content in larvae can be used in calculations of PUFA fluxes through chironomid emergence from water bodies; however, the taxonomic affiliation of the emerged chironomids should be taken into consideration due to the high variability in the PUFA content in Chironomidae species. © 2017, Pleiades Publishing, Ltd.

The Restoration Dynamics of Fallow Vegetation in the Steppe Zone of the Khakassia Republic Based on Terrain and Satellite Data / I. Y. Botvich, T. M. Zorkina // Biophysics. - 2019. - Vol. 64, Is. 2. - P309-315, DOI 10.1134/S0006350919020039 . - ISSN 0006-3509

fallow lands -- long-term variability (structure -- MODIS -- NDVI -- phytomass) -- projective cover -- restoration of natural vegetation -- satellite and terrain research methods
Аннотация: Abstract: The dynamics and specific features of the restoration of forbs–grass–wormwood and wormwood–grass phytocoenoses on fallow lands in the Altai region, the Republic of Khakassia, were determined on the basis of terrain and satellite data. The species composition, structure, and phytomass of the phytocoenoses were revealed. A gradual formation of structural elements of steppe communities in the studied areas was determined. This work showed the usefulness of time series of satellite data on the NDVI (Normalized Difference Vegetation Index) obtained with the use of MODIS (Moderate Resolution Imaging Spectroradiometer) for the study of specific features of restored fallows. In general the biological parameters, projective cover, and phytomass determine the value of the NDVI. Interannual NDVI variability reflects the rate and time period of fallow restoration. From a certain point, the parameters increased and became close to the steppe (control variant). It has been revealed that not only abiotic factors (climate and soils), but also biotic parameters (grazing and recreational load) affect the NDVI. In this connection, the duration of restoration stages does not always correspond to the published data. They vary under different conditions. Climatic data of the Abakan meteorological station (index 29862 in the network of the World Meteorological Organization) for the period from 2000 to 2017 were statistically treated. The long-term annual average norms of temperatures and precipitation amounts (year and month) for the World Meteorological Organization base period of 1961–1990 were calculated. The dynamics of the temperature and precipitation, using long-term series of data, has been analyzed. © 2019, Pleiades Publishing, Inc.

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: The variability of the state of forest vegetation was studied basing on the analysis of NDVI time series (2003–2016) of coniferous and deciduous stands and climate in Krasnoyarsk Territory (Stolby Nature Reserve). The initial data were 8-day Modis satellite information (MOD09Q1 product) and meteorological information from terrestrial weather stations. It was revealed that the trends of the averaged NDVI of forest vegetation for the period May – September and the maximum NDVI were negative. An analysis of the relationship between the dynamics of NDVI forest vegetation and the hydrothermal factor on the territory of the reserve in the 14-year cycle revealed an insignificant correlation between these variables. The negative NDVI trends of coniferous and deciduous stands indicate degradation processes. Deterioration of the state of forest vegetation in the study area detected by satellite data is explained by a combination of factors: climate change, anthropogenic impact of Krasnoyarsk and presence of old-aged forest. © 2018 Space Research Institute of the Russian Academy of Sciences.

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

Climate shifts -- ENSO variability -- pause in global warming
Аннотация: In this study we used HadCRUT4 monthly mean near surface temperature anomalies for 1950–2014 years in order to investigate properties of recent warming. Our aim was to separate changes produced by short-term natural variations and to look on temporal and spatial dynamics of residual temperature anomalies. For this we subtract linear influence of El Nino Southern Oscillation from each grid box of surface temperature measurements. We found that residual global temperature dynamics looks like staircase function: linear trends for three quasi-stable periods 1950–1987, 1988–1997 and 1998–2014 are near zero and near all warming occurred during two shifts of 1987/1988 and 1997/1998 years. Examples of similar staircase behavior of some climate parameters were found in NCEP/NCAR and NASA MERRA reanalysis data. Staircase signal suggests the existence of some regulation mechanism in climate system. This mechanism should maintain global temperature adjusted for El Nino Southern Oscillation near stable in 1950–1987, 1988–1997 and 1998–2014 periods nevertheless all the time growing forcing due to anthropogenic greenhouse gases. © 2015, Korean Meteorological Society and Springer Science+Business Media Dordrecht.

Tracing the North Atlantic decadal-scale climate variability in a late Holocene pollen record from southern Siberia / S. Hildebrandt [et al.] // Palaeogeogr. Palaeoclimatol. Palaeoecol. - 2015. - Vol. 426. - P75-84, DOI 10.1016/j.palaeo.2015.02.037 . - ISSN 0031-0182

Atlantic Multidecadal Oscillation -- Human impact -- Lake level -- Late Holocene -- Non-pollen palynomorphs -- Pollen -- Siberia
Аннотация: This paper presents a new palynological record from a 146. cm long finely laminated sediment core obtained in 2009 from the deep-water meromictic Lake Shira (54°30'38'N, 90°12''09'E; ca. 353. m. a.s.l.) situated in the Khakassian steppe region of southern Siberia between the rivers Ob' and Yenisei. The area is rich in lakes and represents an exceptionally well preserved sequence of Bronze and Iron Age archeological cultures. Little is known about the changes in vegetation and climate of the region during the Holocene. The palynological analysis of the core allows us to partly fill up this gap in current knowledge. The record of pollen and non-pollen palynomorphs presented here covers the past 2450. year interval with an average resolution of 22. years. The results obtained support the interpretation that the late Holocene vegetation changes around Lake Shira are mainly associated with large-scale atmospheric circulation processes controlling the regional water balance rather than with human activities. An attempt to trace human impact in the pollen assemblages provides no clear evidence for anthropogenic activity, except for the last few decades since ca. 1955, though the region has a long history of mobile pastoralists. For explanation of decadal-scale changes in the regional vegetation cover, the Artemisia/Chenopodiaceae (A/C) pollen ratio proved to be a reliable indicator of effective moisture availability. Using available fossil and published instrumental data our study suggests a link between the North Atlantic warmer/colder temperatures and higher/lower atmospheric precipitation (or moisture availability) in southern Siberia at multi-decadal to centennial scales. © 2015 Elsevier B.V.

Аннотация: The main purpose of the work is to investigate the frontal temperature zones using the mathematical model of the oceanic temperature field. The forecast of the frontal temperature zone variability is based on satellite data. The model calculates the temperature under different starting conditions and allows for the mean monthly intensity of solar radiation, components of current velocities, and turbulent diffusion. The input data are the mean monthly current velocities and the radiation heat flows. The model is used to calculate the dynamics of the frontal temperature zones in separate parts of the ocean. Based on the results of numerical experiments presented in the paper we estimated the spatial and temporal ranges of the frontal zone variation affected by the advection of currents, horizontal turbulent heat exchange, and the radiation heat flow in separate parts of the ocean. As examples we consider the basic frontal zones in the Atlantic and the Pacific Oceans. The work also shows possible applications of parametrization of spatial horizontal components of the frontal zones functionally related to the processes of heat advection and diffusion in the absence of exact information about the magnitudes of the current velocities and turbulent mixing.

Аннотация: 1. Aquatic systems are considered to be a main source of essential long-chain n-3 polyunsaturated fatty acids (PUFA), which are preferentially synthesized by microalgae and transferred along food chains to terrestrial consumers. Emerging aquatic insects comprise a significant part of this transfer of the essential PUFA from water to land. Quantitative data on PUFA content and composition are available mainly for rheophilic insects while taxa that are characteristic of wetlands and stagnant water bodies, such as aquatic Heteroptera, remain relatively unstudied. 2. We investigated the role of various waterbug taxa (Heteroptera: Nepomorpha and Gerromorpha) inhabiting different ecoregions in temperate Central Siberia (Russia) as potential sources of PUFA. The ecoregions were steppe, forest-steppe, hemiboreal forest and montane coniferous forest. Although these waterbugs insects are aquatic in both larval and adult stages, they can disperse through the landscape and transfer essential PUFAs from water to land so making them potentially available to terrestrial consumers. 3. Species of Naucoridae, Notonectidae and Corixidae were generally dominant in all ecoregions, attaining maximum biomass in the steppe. We showed that habitat or ecoregion played a major role in the variability of fatty acid composition of Notonectidae and Gerridae but not Corixidae. In contrast, the biochemical composition of the only naucoridae, Ilyocoris cimicoides, was largely affected by life stage. 4. Both the dominant families and species within them differed with respect to their mass-specific contents of essential long-chain PUFA of the n-3 family, namely eicosapentaenoic and docosahexaenoic acids. Corixid species had the highest content of these two essential PUFAs among the waterbug studies, and relative to literature reports for other aquatic insects. Corixids thus appear to be a potentially important vector for transfer of the essential biochemical compounds from water to land, especially in steppe ecoregions with numerous ephemeral water bodies.

Аннотация: Long-term monitoring of the abundance and spatial distribution of 18 widespread species of Odonata has made it possible to assess their contribution to the export of aquatic productivity that entered the Barabinsk forest-steppe ecosystem. The annual emergence of Odonata varies from 0.8 to 4.9 g/m2 of the land area and from 2.3 to 13.3 g/m2 of the water area, which is 4–5 times larger than that in Diptera. The total flux of organic matter from water to terrestrial ecosystems remains relatively stable (sixfold interannual variability) irrespective of large interannual variations in the abundance of separate species (e.g., 42-fold interannual variability in Libellula quadrimaculata). The metal content was determined in nine Odonata species. Export of metals by dragonflies decreases in the series K > Na > Mg > Ca > Fe > Zn > Cu > Mn > Pb > Ni > Cr > Cd. Therefore, odonates appear to be quantitatively and qualitatively important providers of aquatic resources to the forest-steppe landscape of Western Siberia. © 2016, Pleiades Publishing, Ltd.

Аннотация: Humans who eat fish are exposed to mixtures of healthful nutrients and harmful contaminants that are influenced by environmental and ecological factors. Marine fisheries are composed of a multitude of species with varying life histories, and harvested in oceans, coastal waters and estuaries where environmental and ecological conditions determine fish exposure to both nutrients and contaminants. Many of these nutrients and contaminants are thought to influence similar health outcomes (i.e., neurological, cardiovascular, immunological systems). Therefore, our understanding of the risks and benefits of consuming seafood require balanced assessments of contaminants and nutrients found in fish and shellfish. In this paper, we review some of the reported benefits of fish consumption with a focus on the potential hazards of mercury exposure, and compare the environmental variability of fish oils, selenium and mercury in fish. A major scientific gap identified is that fish tissue concentrations are rarely measured for both contaminants and nutrients across a range of species and geographic regions. Interpreting the implications of seafood for human health will require a better understanding of these multiple exposures, particularly as environmental conditions in the oceans change. © Marine Biological Association of the United Kingdom, 2015.

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. © Published under licence by IOP Publishing 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.

tundra -- Holdridge -- vegetation -- biotemperature -- precipitation -- NDVI
Аннотация: The tundra was divided into different classes depending on the temperature and precipitation in accordance with the Holdridge classification. Dry, moist, wet, and rainy tundras were distinguished. Datasets on climate variability were obtained from the Climatic Research Unit website () for the period from 2001 to 2017. The long-term (2001-2016) dynamics of phytomass for different tundra classes was studied on the basis of the Normalized Differential Vegetation Index (NDVI). The positive long-term dynamics of NDVI-vegetation for the tundra classes studied was revealed. This trend correlates with the positive dynamics of the mean annual biotemperature. It was shown that the impact of global climate change on vegetation of different tundra classes is ambiguous. For the dry tundra, the increase in NDVI in May and June was higher than for the rainy tundra. This correlates with the fact that the increase in the mean monthly temperatures in May and June on the territory of the dry tundra is greater than on the territory of the rainy tundra.

Аннотация: The relevance of the work is caused by the need to study seasonal variations in the volume and composition of sedimentation flows in modern lakes and their relationship with weather and climatic factors, which can serve as a basis for reconstructing climatic changes in the past. The main aim: to assess seasonal changes in the mass, velocity and chemical composition of sedimentary material entering Lake Shira on the basis of generalization and analysis of the results of multiyear annual monitoring of the material of sedimentation traps incubated in the lake. Object of the study was the drainless, slightly saline meromictic lake Shira, located in the steppe intermontane depression on the territory of the Republic of Khakassia. Methods: long-term seasonal monitoring of sedimentary material forming bottom sediments using sedimentation traps incubated in the lake; study of the obtained material for a wide range of parameters (biological, hydrochemical, lithological-geochemical, granulometric, etc.) by various conventional methods, including the method of X-ray fluorescence microanalysis on synchrotron radiation beams (XRF-SI), adapted for the study of bottom samples; computer statistical analysis of the data obtained (multiple regression method, cross-correlation analysis, etc.) in order to identify the relationship between regional temperatures and the chemical composition of the deposited material with the construction of a regression model. Results. Based on the study of the amount and elemental composition of the sedimentary material of the seasonal bottom traps of Lake Shira, collected for 2012-2017, a dynamic model of the seasonal influx of sedimentary flows in lakes of this landscape-geochemical type was formulated. It has been established that the most intensive sedimentation of the material occurs in the summer-autumn period, less - in the winter-spring period. At the same time, in spring, the accumulation of allochthonous (terrigenous) aleurite material, supplied with flood waters, predominates; in the summer-autumn period, simultaneously with the deposition of clastogenic pelitic material, biogenic and chemogenic materials are accumulated in sediments in large quantities. In winter, clastogenic and biogenic processes of sedimentation practically stop, only chemogenic sedimentation of carbonates is observed. It was established that the sedimentation of allochthonous material entering the reservoir occurs during two-three months, which indicates a certain inertness of sedimentation. The presence of a stable relationship between the mass and chemical composition of terrigenous material entering the lake with the regional temperature of the near-surface air, which is one of the main regulators of the water balance of the reservoir, is shown.

Аннотация: The variability of craniological characters has been studied for anadromous and lacustrine forms of whitefish Coregonus lavaretus (Linnaeus, 1758) from waterbodies of the Karelian coast of the White Sea. The significant phenotypic plasticity of craniological characters of the whitefish depends on the environmental conditions. Moreover, there is a correlation between indexes of the craniological traits (except for the index of the snout length) and the body and/or head length (allometric effect). These results suggest that it is unreasonable to separate anadromous and lacustrine forms of C. lavaretus as distinct taxonomical units and argues for the invalidity of C. pidschian and C. oxyrinchus species.
