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 traitbased 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.

    Law of the Minimum paradoxes
[Text] : статья / A. N. Gorban [et al.] // Bulletin of Mathematical Biology. - 2011. - Vol. 73, Iss. 9. - p. 2013-2044DOI 10.1007/s11538-010-9597-1 . -

Аннотация: The “Law of the Minimum” states that growth is controlled by the scarcest resource (limiting factor). This concept was originally applied to plant or crop growth (Justus von Liebig, 1840, Salisbury, Plant physiology, 4th edn., Wadsworth, Belmont, 1992) and quantitatively supported by many experiments. Some generalizations based on more complicated “dose-response” curves were proposed. Violations of this law in natural and experimental ecosystems were also reported. We study models of adaptation in ensembles of similar organisms under load of environmental factors and prove that violation of Liebig’s law follows from adaptation effects. If the fitness of an organism in a fixed environment satisfies the Law of the Minimum then adaptation equalizes the pressure of essential factors and, therefore, acts against the Liebig’s law. This is the the Law of the Minimum paradox: if for a randomly chosen pair “organism–environment” the Law of the Minimum typically holds, then in a well-adapted system, we have to expect violations of this law. For the opposite interaction of factors (a synergistic system of factors which amplify each other), adaptation leads from factor equivalence to limitations by a smaller number of factors. For analysis of adaptation, we develop a system of models based on Selye’s idea of the universal adaptation resource (adaptation energy). These models predict that under the load of an environmental factor a population separates into two groups (phases): a less correlated, well adapted group and a highly correlated group with a larger variance of attributes, which experiences problems with adaptation. Some empirical data are presented and evidences of interdisciplinary applications to econometrics are discussed.

salt lake -- measuring hydro-values in situ -- ecological condition

Аннотация: To understand the mechanisms of formation of water quality it is necessary to study both biological and chemical properties of a lake as well as its hydro regime. For many years researchers have focused on the study of chemistry and biology of Lake Shira (situated in Siberia), but a detailed investigation of its hydro regime has become possible only recently with the development of modern measuring instruments. Using the latest generation of measuring devices we have obtained the hydrophysical characteristics of the stratified salt lake in situ (air and water temperature, wind strength and direction, water velocity). Relationships between the measured data have allowed us to analyze the flow in the lake as a whole, thus outlining the problem of determining lake ecological status in the period under observation.

    Peculiarities of the antioxidant activity of tissues of rheophilic zoobenthic species in accordance to the results of chemiluminescent analysis
/ G. V. Makarskaya, A. V. Andrianova, S. V. Tarskikh // Contemp. Probl. Ecol. - 2016. - Vol. 9, Is. 5. - P574-581, DOI 10.1134/S1995425516050103 . - ISSN 1995-4255
Аннотация: Adaptations of living organisms to the environment are formed and manifested at different levels, from molecular to biocoenotic. Nowadays, the metabolic antioxidant system (AOS) is considered the key part of the process of adaptation; its activation is considered a general response of biota to the negative effect of the environment. The usage of AOS components as biomarkers of the stress condition in hydrobionts has good prospects; it is actively applied in the monitoring of aquatic ecosystems. Here, the kinetics of the free radical formation in various zoobenthic species from the Yenisei River (amphipods, oligochaetes, leeches, and chironomids) and in the amphipods from the Us River (a small mountain river, the Yenisei tributary) is analyzed. The parameters of kinetics of radical formation were registered in vitro in the homogenates of hydrobionts tissues under the initiation of the oxidative stress by the hydrogen peroxide using luminol-dependent chemoluminescence. In amphipods, unlike other invertebrates, the antioxidative activity is characterized by two chemiluminescent peaks. In addition, the kinetics of free radical elaboration has interspecific and agerelated variability in amphipods. In Gmelinoides fasciatus Stebb., the peak of the free radical elaboration and their total number significantly exceeded these parameters for Gammarus sp. and Eulimnogammarus viridis Dybowsky in a 60-min period. The increase of the production of free radicals in E. viridis and Gammarus sp. and its decrease in G. fasciatus were age-dependent. A significantly higher production of free radicals has been registered in G. fasciatus and E. viridis inhabiting the zone of elevated anthropogenic load in the Yenisei River. © 2016, Pleiades Publishing, Ltd.

salt stratified lake -- mathematical modelling

Аннотация: Salt stratified Lake Shira is the subject of extensive research because of its central role in the Khakassia (Russia) resort area. Hydro regime influences both biological and chemical properties of a lake. Generally mathematical modelling of Lake Shira hydrophysics was based on assumption of a uniform horizontal initial distribution of salinity. It was believed that freshening had little effect on the lake hydrophysics because of the small Son River tributary. This work is an attempt to determine the effect of freshened lake area on the lake hydrophysics and its ecological condition. 3D mathematical modelling based on modern computer packages is used to study in detail the influence of non-uniform salinity due to the influx of the Son River on the flow structure in Lake Shira. Numerical simulation has shown that even a relatively small area of fresh water in shallow part of this lake has a significant impact on the wind currents in the lake if they are accompanied by internal waves

    Оценка экологического состояния водоемов Алтайского края с применением гидрооптических методов и биотестирования
[Текст] : статья / П. В. Постникова, В. С. Филимонов, С. Е. Медведева // Вода: химия и экология. - 2016. - № 4. - С. 56-62 . - ISSN 2072-8158
   Перевод заглавия: Assessment of ecological state of water bodies of Altai territory using hydro-optical methods and biotesting
Аннотация: Работа посвящена исследованию возможностей комбинации оптических методов и биотестирования для оценки экологического состояния природных водных экосистем. В качестве природных водоемов были выбраны 5 озер (оз. Горькое, Безымянное, Лапуниха, Большое Островное, Новенькое) из 4 районов Алтайского края (Мамонтовского, Угловского, Рубцовского и Локтевского). В ходе исследования определялись оптические параметры, которые дают экологическую оценку водного объекта: концентрация хлорофилла «а» (трофический статус водоема), фотосинтетическая активность водорослей (или их жизненный статус), содержание растворенных органических и взвешенных неорганических веществ. В данной работе применены методы биотестирования, основанные на изменении интенсивности свечения светящихся бактерий. Полученные в ходе обследования оптические и биологические характеристики позволили оценить состояние объектов, с одной стороны, по показателям, характеризующим среду (оптические показатели), с другой стороны, по показателям, характеризующим состояние биоты (методы биолюминесценции). Предлагаемая в работе комбинация методов контроля позволяет оперативно выделить наиболее неблагоприятные с экологической точки зрения объекты и решить вопрос о необходимости проведения других аналитических процедур.
The paper investigates the possibilities of a combination of optical methods and biotestingfor the assessment of ecological state of natural water ecosystems. As natural reservoirs, five lakes(Gorkoe, Bezymyannoe, Lapunikha, Bolshoe Ostrovnoe, Novenkoe) from 4 regions of Altai Krai (Mamontovskiy, Uglovskiy, Rubtsovskiy and Loktevskiy) were taken. The study determined the optical parameters that provideecological assessment of a water body: concentration of chlorophyll «a» (the trophic state of the reservoir), photosynthetic activity of algae (or their life status), dissolved organic and suspended inorganic matter. In this work, we applied methods of biotesting, based on the change in luminescence intensity of luminous bacteria. Optical and biological characteristics obtained in the research allowed us to assess the condition of the objects, on the one hand, by the parameters of condition of environment (optical parameters) and, on the other hand, by the indicators characterizing the state of the biota (bioluminescence methods). The combination of control methods offered in this paper allows to quickly identify the most unfavorable objects from the ecological point of view and solve the problem of the necessity of other analytical procedures.

Аннотация: Адаптации живых организмов к условиям окружающей среды формируются и проявляются на самых различных уровнях - от молекулярного до биоценотического. В настоящее время метаболическая антиоксидантная система (АОС) считается ключевым звеном адаптационных процессов, а ее активация рассматривается как универсальный отклик биоты на негативное воздействие окружающей среды. Использование компонентов АОС в качестве биомаркеров стрессовых воздействий на гидробионтов активно внедряется и имеет большие перспективы в системе мониторинга водных экосистем. В данной работе проанализирована кинетика образования свободных радикалов у различных представителей зообентоса из р. Енисей (амфиподы, олигохеты, пиявки, хирономиды) и амфипод из р. Ус (малая горная река, приток Енисея). Параметры кинетики радикалообразования регистрировали методом люминолзависимой хемилюминесценции при инициировании оксидативного стресса перекисью водорода in vitro в гомогенатах тканей гидробионтов. Выявлено, что у амфипод, в отличие от других беспозвоночных, процесс антиокислительной активности характеризуется двумя вспышками хемилюминесценции. Кроме того, у амфипод наблюдались межвидовые и возрастные отличия по параметрам кинетики генерации свободных радикалов. У Gmelinoides fasciatus Stebb. пик интенсивности генерации свободных радикалов и их общее количество за 60-минутный период регистрации достоверно превосходили данные показатели для Gammarus sp. и Eulimnogammarus viridis Dybowsky. С возрастом наблюдалось увеличение объема продукции свободных радикалов у E. viridis и Gammarus sp. и снижение у G. fasciatus. Отмечено достоверно более высокое значение объема генерации свободных радикалов у G. fasciatus и E. viridis, обитающих в зоне р. Енисей с повышенной антропогенной нагрузкой.

Nowadays, the metabolic antioxidant system (AOS) is considered to be the key part of adaptive processes, and its activation is regarded as a general response of biota to the negative impact of the environment. The usage of AOS components as biomarkers of stressful influence on hydrobionts has good prospects and is actively applied in the monitoring system of aquatic ecosystems. In this paper the kinetics of free radical formation in various zoobenthos representatives from the Yenisei River (amphipods, oligochaetes, leeches, chironomids) and in amphipods from the Us River (a small mountain river, the Yenisei tributary) is analyzed. Parameters of kinetics of radical formation were registered using the method of luminoldepended chemoluminescence under the initiation of oxidative stress with hydric dioxide in vitro in homogenates of hydrobionts tissues. It was revealed that in amphipodes, as opposed to other invertebrates, the process of antioxidative activity is characterized by two chemiluminescent flashes. What is more, interspecies and age-related differences in parameters of the kinetics of free radicals formation were noticed in amphipodes. In Gmelinoides fasciatus Stebb. the intension peak of the formation of free radicals and their total number during the 60-minute registration period authentically exceeded these parameters for Gammarus sp. and Eulimnogammarus viridis Dybowsky. With age, the increase in volume of production of free radicals in E. viridis and Gammarus sp. and its decrease in G. fasciatus were observed. The authentically higher value of volume of production of free radicals in G. fasciatus and E. viridis inhabiting the zone of the Yenisei River with heightened anthropogenic load was marked.

Аннотация: Forecasting response of the biosphere and regional ecosystems to observed and expected climate change is the fundamental problem with obvious practical significance. Fundamental non-linearity of the climate system and biosphere makes feasible implementing multiple states and threshold processes in the biosphere-climate system (BCS) in response to gradually increasing influence factor (greenhouse gas concentrations growth). Really time series analysis of global temperature and other global and local parameters indicates the presence of abrupt transitions between stationary states. Identification of the switching mechanisms using general circulation models of the atmosphere and the ocean is associated with the obvious difficulties due to their complexity. Understanding the nature of such switches at qualitative level can be achieved by using a conceptual small-scale models. Some variants of possible mechanisms capable of generating these shifts and simultaneously supporting quasi-stationary periods between them are discussed.

Аннотация: Yenisei River is the main Siberian river, it is one of the seven largest rivers in the world and it is the most high-water river in Russia. It is known that the emergence of large hydraulic structures causes a prolonged, and sometimes irreversible, destabilization of aquatic ecosystems. The construction of Krasnoyarsk hydroelectric power station (HPS) caused global changes in hydrological, hydrochemical and hydrobiological regimes in the Yenisei River. The Yenisei River in the downstream of the HPS does not freeze in winter over 100-300 km from the dam. Hydropower engineering has caused global changes in Yenisei’s zoobenthos, especially in the HPS downstream. The stoneflies and blackflies have almost disappeared from the benthic fauna, the density and number of caddisflies and mayflies species have significantly decreased. Quantitative characteristics of zoobenthos in the area from the dam to the Angara’s estuary have greatly increased: quantity – by more than 2 times, biomass – by 5 times. The growth of indicators is determined, firstly, by the spread of Gammaridae from Lake Baikal through the Angara river upstream of the Yenisei, while their proportion in the total zoobenthos biomass increased by 10 times. This work is devoted to the spatial dynamics of Baikal endemic amphipods in the Yenisei, which spread far beyond the Baikal not only downstream, but also upstream. The results of expedition hydrobiological studies, conducted in 2015-2016 in several zones of the Yenisei River from its head to the mouth, are presented. Throughout the river, Gmelinoides fasciatus quantitatively dominated among the Gammaridae, Philolimnogammarus viridis took the second place. Only in the lower reaches and in the delta of the Yenisei the leading positions were transferred to Pontoporeia affinis-a representative of the estuary-relic complex of organisms. Baikal endemics actively populated the Upper Yenisei section below the Sayano-Shushensky hydroelectric power station, especially in the areas of massive macrophyte distribution. There is a divergence of ecological niches in G. fasciatus and Ph. viridis in the Yenisei: the dominant prefers silty sand-and-shingle biotopes with a calm speed rate; the subdominant tends to prefer stony-pebble bottom washed by a rapid current. Over the past 15 years, the density and proportion of crustaceans in the zoobenthos have increased in the Angara-Podkamennaya Tunguska section. © SGEM2018 All Rights Reserved.

    The use of satellite information (MODIS/Aqua) for phenological and classification analysis of plant communities
/ Y. Ivanova [et al.] // Forests. - 2019. - Vol. 10, Is. 7, DOI 10.3390/f10070561 . - ISSN 1999-4907
Аннотация: Vegetation indices derived from remote sensing measurements are commonly used to describe and monitor vegetation. However, the same plant community can have a different NDVI (normalized difference vegetation index) depending on weather conditions, and this complicates classification of plant communities. The present study develops methods of classifying the types of plant communities based on long-term NDVI data (MODIS/Aqua). The number of variables is reduced by introducing two integrated parameters of the NDVI seasonal series, facilitating classification of the meadow, steppe, and forest plant communities in Siberia using linear discriminant analysis. The quality of classification conducted by using the markers characterizing NDVI dynamics during 2003-2017 varies between 94% (forest and steppe) and 68% (meadow and forest). In addition to determining phenological markers, canonical correlations have been calculated between the time series of the proposed markers and the time series of monthly average air temperatures. Based on this, each pixel with a definite plant composition can be characterized by only four values of canonical correlation coefficients over the entire period analyzed. By using canonical correlations between NDVI and weather parameters and employing linear discriminant analysis, one can obtain a highly accurate classification of the study plant communities. © 2019 by the authors.

Аннотация: Monitoring of animals in the wild using camera traps is one of the promising ways for monitoring animal behaviour and estimation of dynamic of changes in natural systems over the large areas. The installation of camera traps in a predefined place such as animal shelters, trails, watering places provides unique information that is not available by applying other monitoring methods. Present, a lot of methods and algorithms have been developed that allow us to recognize the natural images taking into account the variability of shooting conditions, illumination, location and posture of the animal, as well as a complex textural background, representing various states of the forest, steppe, mountain and tundra landscapes. This paper presents the results of analysis and systematization of monitoring data from images obtained on the protected natural territories in the Krasnoyarsk region. The authors propose the special structure of a centralized data warehouse for an intelligent ecosystem monitoring system. The structure of the data warehouse combines historical, operational and reference data. The content of structural elements of the data warehouse is described in detail. The developed data warehouse combines monitoring data from different sources and makes up a united informational resource for further data processing and solving analytical tasks of environmental monitoring. © 42nd International Convention on Information and Communication Technology, Electronics and Microelectronics, MIPRO 2019 - Proceedings.

В частности, структуру экосистемы озера (в летний сезон), выраженную отношением граничных поверхностей дисперсных компонентов, для ряда зоопланктон - простейшие - фитопланктон - бактерии - органический детрит - органо-минеральный детрит (ОМД) можно представить соотношением 1:1:10:30:60:1400. Полевые исследования дополнены лабораторными экспериментами по выявлению роли минерального взвешенного вещества в функционировании экосистем. Большая величина поверхности минеральной взвеси ($100\div200 м. /м. $), значительное количество АОВ (60-90%) и прикрепленной бактериальной микрофлоры (около 40%) определяет активную минерализацию органики через поверхностные взаимодействия. Из этого следует более высокая продуктивность фитопланктона и последующих звеньев пищевой цепи, что играет значительную pоль в функциониpовании экосистемы лессовых водоемов, pегулиpуя потоки трансфоpмации веществ и их концентpаций в сpеде чеpез pазветвленную гpаничную повеpхность. Предложена схема трофометаболических связей планктонного сообщества с включением органо-минерального детрита как важного функционального звена. Оценены адсорбция (прикрепление) бактерий на ОМД в зависимости от массы адсорбированного органического вещества и численности бактериопланктона, а также активность прикрепленного (и агрегированного) бактериопланктона по сравнению со "свободно живущим" в толще воды. Выявлена зависимость удельной первичной продукции от удельной площади поверхности клеток водорослей (S/V) и показана связь S/V с сапробностью водной среды для озера. На основе экспериментальных данных по светорассеянию вод озера Ханка и модельных сред теоретически в приближении Релея-Ганса-Дебая выяснена структура хориона (минеральное ядро+органическая оболочка). Показано влияние минеральной взвеси на активность биохимических процессов, снижение токсичности среды и повышение выживаемости водных организмов.
The new lead of investigation related to the presence in water bodies of internal active phase boundaries and their role to forming of the ecosystems functional structure has been enunciated. The methods for studying the functional structure of the water ecosystems, on the basis of investigating phase boundary areas, were developed. On the basis of this methods the common content of suspended matter, number of suspended particles, its sizies, the content of dissolved organic matter (DOM), part of adsorbed DOM (AOM), the areas of dispersed phase boundaries for mineral and biotic suspended matter were investigated in waters of Khanka lake. The spatial dispersed structure of lake ecosystem attributed with the suspended matter-water phases boundary for main suspended components has been studyed. In particular case the ecosystem structure (in summer season) pronounced with ratio dispersed boundary surfases for sequence zooplankton - protozoa - phytoplankton - bacteria - organic detritus - organo-mineral detritus is 1:1:10:30:60:1400. The field researches are supplemented by laboratory experiments on detection of a role of mineral suspended matter in ecosystems functioning. The great size of surfase of mineral suspended matter ($100\div200 m. /m. ), high amount of DOM adsorbed on huge surface (60-90%) and adsorbed bacterioplankton (about 40%) supposes the active mineralization of DOM by attached microorganisms through the intermediary of surface coupling. Hence more high productivity of the phytoplankton and the subsequent links of the food chain follows play the great part in ecosystem functioning of loess water bodies regulating fluxes of substances transformation and its concentrations in a medium through the intermediary of ramified boundary surface. The scheme of trophometabolic bonding of the planktonic community with incorporating of organo-mineral detritus as important functional link was proposed. The adsorption of bacteria to organo-mineral detritus is appreciated in dependence from mass of adsorbed organic matter and of bacterioplankton numbers. The activity of attached (and aggregated) bacterioplankton is evaluated on a comparison with " freely living " in water mass. Connection of a specific primary production with specific area of algae cells surface (S/V) and connection S/V with saprobity of a water medium are shown. Theoretically in Rayleigh-Gans-Debye approximation on the basis the experimental data on a scattering of light of Khanka lake waters and model mediums the chorion structure (mineral core + organic envelope) on level of separate particle is clarified. The influence of mineral suspended matter for the decrease of toxicity of a medium and for the increase of the survival of water organisms is appreciated.

Аннотация: The paper presents the first steps towards an authorial integration methodology for heterogeneous data. Exposing information from multiple heterogeneous data sources demands a global (mediated) schema. We need a model to couple with the mismatches between schemata of different sources and to provide uniform access to the data. The virtual global schema is apparently more convenient for assembling big data sources because of useless time consumption during the processes of materialization and synchronization. Thus, an integral analytical model has been proposed as the global schema of heterogeneous data sources. The suggested model provides virtual integration of complex and diverse information for further analytical processing. It combines the original multidimensional design and lattice structure according to the formal conceptual analysis. The main goal of the paper is to suggest an approach to automatic mapping between the schemata of the disparate data sources and virtual integral analytical model with human moderation. © 2019 Copyright is held by the owner/author(s).
