Аннотация: Using idealized models of the magnetosheath and magnetosphere magnetic fields, plasma densities, and plasma flow, we test for the steady state viability of processes mediating the interaction between the solar wind and the Jovian magnetosphere. The magnetopause is modeled as an asymmetric paraboloid with variable asymmetry. The subsolar standoff of the magnetopause has been shown to exhibit a bimodal probability distribution (Joy et al., 2002). Only the expanded magnetopause is considered, with a standoff of similar to 90 R-J. We test where on the magnetopause surface large-scale reconnection may be affected by either a shear flow or diamagnetic drift due to a pressure gradient across the magnetopause boundary. We also test for the onset of the Kelvin-Helmholtz instability. We find that reconnection is inhibited on the dawn flank due to the large shear flows in this region, regardless of magnetopause shape or interplanetary magnetic field orientation. The presence of a high energy plasma population in the magnetosphere may inhibit reconnection over much of the magnetopause area, except when the fields are antiparallel. Additionally, most of the dawn flank of the magnetopause is Kelvin-Helmholtz unstable, regardless of magnetopause asymmetry; and the dusk flank tailward of the planet is Kelvin-Helmholtz unstable when the magnetopause is highly oblate.

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.

Local Information Access May Cause a Chaos in Migration
[Текст] : статья / M. G. Sadovsky, M. Yu. Senashova // Journal of Siberian Federal University. Mathematics & Physics = Журнал Сибирского федерального университета. Математика и физика. - 2013. - Т. 6, № 1. - С. 105-113
Перевод заглавия: Локальная информированность может приводить к хаотической миграции
Аннотация: A novel model of the targeted migration of a population separated into two subpopulations is proposed. The model is implemented for the local information access. Migration is not random and yields the maximization of a net reproduction, in general; specific version of this general rule is proposed. The local information access means the total lack of knowledge on the environmental conditions and transfer cost at the immigration station, for beings occupying the given station. Various regimes for the models are studied. A reciprocal chaotic-like migrations may take place, for some reasonable parameters figures.

Аннотация: В работе описана модель динамики одновидового пространственно распределенного сообщества глобально информированных особей. Особи распределены по двум пространственно удаленным стациям. Проводится сравнение динамики численности популяции в зависимости от рефлексивного поведения особей данной популяции. Сравниваются популяция полностью нерефлексирующих особей и популяция, часть особей которой рефлексирует поведение остальной части популяции. Представлены два варианта вычисления численностей в следующем поколении: рефлексирующие и нерефлексирующие особи рассматриваются как один вид и как два подвида. Рефлексирующие и нерефлексирующие особи могут занимать одну из двух стаций и совершать перемещения из стации в стацию. Такие перемещения мы будем называть миграцией. В данной модели предполагается, что особи являются глобально информированными, то есть располагают полной информацией об условиях существования в стациях, численности субпопуляций и о цене перемещения из стации в стацию. Мы рассматриваем модель с оптимизационной миграцией, то есть перемещения особей из стации в стацию являются целенаправленными и совершаются при выполнении условий миграции. Проведены численные эксперименты, которые показали, что рефлексивное поведение для одновидовой популяции не имеет существенного влияния на динамику численности. Если рефлексирующие и нерефлексирующие особи рассматриваются как два отдельных подвида, тогда динамика численности в присутствии рефлексирующих особей отличается от динамики полностью нерефлексирующих особей.
A model of spatially distributed population is provided with global information access of the beings. These latter occupy two stations, and the migration is a transfer from station to station. Dynamics of a population is compared for two cases: reflexive vs. non-reflexive behavioural pattern. In particular, the dynamics of two subpopulations is compared where the former realizes reflexivity, and the latter does not. Two versions of the models are considered: once reflexive and non-reflexive subspecies are stipulate to comprise a population, and another version stipulates that reflexive beings comprise a discrete subspecies. Both reflexive and non-reflexive subspecies may occupy a station and transfer between them. These transfers are called migration. The model implies the global information access, i.e. the beings knows everything towards environmental conditions in both stations, subpopulations abundancies in both stations, and transfer cost. We study an optimal migration where the migration act is targeted; the migration starts if relevant constrains are met. Numerical simulations were carried out to show that reflexivity has no significant impact on the population dynamics. On the contrary, when rfeflexive and non-reflexive subpopulations are considered as two distinct species, the reflexivity affects the dynamics.

Ballast quarries -- Environmental efficiency -- Geographical orientation of nonworking pit walls -- Road metal production -- Siberia
Аннотация: Slow-rate development of mineral resources in Siberia is connected with remoteness of mineral fields and deficiency in hard-surface roads. The approval of the government transport system program in Siberia requires boosting road metal production and quarrying expansion. Mined-out voids of depleted quarries disturb lands and remain bare for a long time. The situation in the Krasnoyarsk Territory is of particular concern. It is urgently required to find planting methods for mined-out ballast quarries. The obstacle is the traditional geometry of mined-out open pits, with steep walls and vast bottom flooded with atmospheric precipitations. Ecological monitoring of mined-out surface mines in the Krasnoyarsk Territory and most effective vegetation of mined-out voids shows that, given the local climate (long cold winter and short hot summer), population of trees is higher on the southern and eastern pit walls, where moisture content is higher and trees are less dehumidified under the sun in simmer; of no less significance is flatness of slopes and weak inclination (3-5°) of roads towards pit walls, as well as presence of fertile soil layer in the walls. On special purpose plots of land 0.2 ha in area, trees have been counted per each element of a quarry, which makes the basis to develop recommendations on environmentally optimal shape of quarries: maximum area of the southern and eastern pitwalls to be slightly sloping (15-24°), minimum technologically reasoned area of bottom is shifted northwestward. The study is in accordance with the Fundamental Research Program of the National Academies of Sciences for 2013-2020 and the research plan of the Nauka Design and Engineering Center, ICT SB RAS for 2013-2017, under the project "Information Support Models and Technologies for Evaluation, Forecasting and Management of Regional Eco-Systems, Territorial Infrastructure and Natural and Industrial Safety".

Model of Prey-Predator Dynamics with Reflexive Spatial Behaviour of Species Based on Optimal Migration
[Text] / M. Sadovsky, M. Senashova // Bull. Math. Biol. - 2016. - Vol. 78, Is. 4. - P736-753, DOI 10.1007/s11538-016-0159-z. - Cited References:58

Аннотация: We consider the model of spatially distributed community consisting of two species with "predator-prey" interaction; each of the species occupies two stations. Transfer of individuals between the stations (migration) is not random, and migration stipulates the maximization of net reproduction of each species. The spatial distribution pattern is provided by discrete stations, and the dynamics runs in discrete time. For each time moment, firstly a redistribution of individuals between the stations is carried out to maximize the net reproduction, and then the reproduction takes place, with the upgraded abundances. Besides, three versions of the basic model are implemented where each species implements reflexive behaviour strategy to determine the optimal migration flow. It was found that reflexivity gives an advantage to the species realizing such strategy, for some specific sets of parameters. Nevertheless, the regular scanning of the parameters area shows that non-reflexive behaviour yields an advantage in the great majority of parameters combinations.

Relationships between the biomass and production of bacterio- and phytoplanktonic communities
/ A. D. Aponasenko, L. A. Shchur // Microbiology. - 2016. - Vol. 85, Is. 2. - P243-248, DOI 10.1134/S0026261716020028

bacterioplankton -- biomass ratios -- dissolved organic matter -- equilibrium density of bacteria -- phytoplankton -- specific bacterial production -- specific primary production
Аннотация: Quantitative ratios of the biomasses of bacterio- and phytoplankton, interrelation of their production characteristics, and association of the functional characteristics with environmental factors were studied for Lake Khanka, the Yenisei River, and the Krasnoyarsk Reservoir. The ratio between the biomasses of bacterioplankton (Bb) and phytoplankton (Bp) in these water bodies was shown to vary within the range exceeding three orders of magnitude. Bacterioplankton biomass was relatively stable and varied from sample to sample by an order of magnitude. In more than 50% of the samples (total sample number, 495), bacterioplankton biomass exceeded that of the phytoplankton. The average Bb/Bp ratios for Lake Khanka, Yenisei River, and Krasnoyarsk Reservoir were 5.1, 2, and 1.4, respectively. Increased Bb/Bp ratios were found to correlate with elevated specific (per unit biomass) phytoplankton production. This finding indicated additional supply of biogenic elements to phytoplankton due to their recycling by bacterial communities. The ratio between bacterioplankton and phytoplankton production for Lake Khanka varied from year to year (0.07 to 0.76). For the Yenisei River and the Krasnoyarsk Reservoir these ratios were on average 0.19 and 0.27, respectively. According to the literature data for other water bodies, bacterial production may reach from 10 to over 100% of the primary production. The equilibrium density of bacterioplankton (maximal density of the population) in Lake Khanka was ~1.5 times higher than in the Yenisei River and the Krasnoyarsk Reservoir due to higher content of suspended mineral matter and associated organo-mineral detritus in the lake. The interaction between dissolved organic compounds sorbed on the surface of mineral particles results in chemical alteration of biochemically stable substrate into compounds which may be assimilated by aquatic microorganisms. © 2016, Pleiades Publishing, Ltd.

Global kinetic hybrid simulation for radially expanding solar wind
/ S. Dyadechkin [et al.] // J. Geophys. Res. Space Phys. - 2017. - Vol. 122, Is. 8. - P7854-7864, DOI 10.1002/2017JA023992
. - ISSN 2169-9380
Аннотация: We present the results of a 1-D global kinetic simulation of the solar wind in spherical coordinates without a magnetic field in the region from the Sun to the Earth's orbit. Protons are considered as particles while electrons are considered as a massless fluid, with a constant temperature, in order to study the relation between the hybrid and hydrodynamic solutions. It is shown that the strong electric field in the hybrid model accelerates the protons. Since the electric field in the model is related to electron pressure, each proton in the initial Maxwellian velocity distribution function moves under the same forces as in the classical Parker Solar wind model. The study shows that the hybrid model results in very similar velocity and number density distributions along the radial distance as in the Parker model. In the hybrid simulations, the proton temperature is decreased with distance in 1 order of magnitude. The effective polytropic index of the proton population slightly exceeds 1 at larger distances with the maximum value ?1.15 in the region near the Sun. A highly non-Maxwellian type of distribution function is initially formed. Further from the Sun, a narrow beam of the escaping protons is created which does not change much in later expansion. The results of our study indicates that already a nonmagnetized global hybrid model is capable of reproducing some fundamental features of the expanding solar wind shown in the Parker model and additional kinetic effects in the solar wind. ©2017.

Аннотация: Исследованы сообщества донных беспозвоночных р. Чулым в верхнем и среднем течении. Зообентос исследованного участка Чулыма весной состоял из поденок, олигохет, хирономид и представителей группы «прочие». Осенью выросла доля по численности хирономид и ручейников, а доля олигохет и «прочих» снизилась. Биомасса складывалась в основном из поденок и «прочих». Весенняя численность составила 1,1 тыс. экз./м2, биомасса 8,2 г/м2. Осенью количественные показатели практически не изменились (1.4 тыс.экз./м2, 10,6 г/м2). Минимальная плотность зообентоса (0,6 тыс. экз./м2 и 1,3 г/м2) зафиксирована в районе осетрово-нельмового Заказника «Чулымский», что подтверждается и более ранними исследованиями. Наибольшая биомасса характерна для заиленных биотопов при слабом течении (14-16 г/м2 весной). Осенью существенно увеличилась плотность бентоса среди высшей водной растительности (2,4 тыс.экз./м2 и 17 г/м2). По сравнению с 1970-ми гг. в донных сообществах выросла доля гетеротопных насекомых, при этом доля олигохет, моллюсков и хирономид в биомассе снизилась в 4-5 раз; отмечается тенденция увеличения общей биомассы бентоса.
The benthic invertebrate communities in the river Chulym were studied in the upper and middle reaches. The zoobenthos of the investigated area of the Chulym river in the spring consisted of mayflies, oligochaetes, chironomids, and representatives of the group «other». In the fall the proportion of the numbers of chironomids and caddisflies increased, whereas the proportion of oligochaetes and «other» decreased. Biomass was composed mainly of mayflies and «other». The spring population was 1,1 thous. ind/m2, biomass - 8,2 g/m2. In the fall quantitative indicators remained almost unchanged (1,4 thous. ind/m2, 10,6 g/m2). The minimum density of zoobenthos (0,6 thous. ind./m2 and 1,3 g/m2) was recorded in the area of sturgeon-nelmous Reserve «Chulymskiy», which is confirmed by earlier studies. The greatest biomass is typical for silted habitats at low flow (14 - 16 g/m2 in spring). In autumn the density of benthos among the higher aquatic vegetation increased significantly (2.4 thous. ind/m2 and 17 g/m2). Compared to the 1970-ies in sediment communities the percent of heterotopic insects increased, while the percent of oligochaeta, mollusca, and chironomids in the biomass decreased by 4-5 times; there is a trend of increase in total biomass of benthos.

Аннотация: В результате многолетних натурных наблюдений определены факты влияния повышенной скорости сброса воды через шлюзы плотины Красноярской ГЭС на динамику фитопланктона р. Енисей ниже плотины. Высказано предположение, что механизм влияния данного фактора заключается в следующем: повышенный сброс воды изменяет температуру воды реки в нижнем бьефе, что в свою очередь влияет на динамику численности фитопланктона. Справедливость данного предположения подтверждается данными 2008-2016 гг. Полученные результаты могут быть применены для составления прогнозов динамики фитопланктона в нижнем бьефе в следующие временные периоды.
Using multiyear measurements, we investigated the influence of high flow rates at Krasnoyarsk hydropower station (Krasnoyarsk HPS) on the phytoplankton population of Yenisei River downstream the dam. We propose the hypothesis that flow rate variations change water temperature, which is influencing the phytoplankton dynamics. This hypothesis is verified by measurements conducted in 2008-2016. The results obtained can be used for the forecast of phytoplankton dynamics downstream the dam.

Аннотация: Представлены результаты экспедиционных гидробиологических исследований, проведённых в 2015-2016 гг. в нескольких зонах русла р. Енисей от истока до устья. Данная работа посвящена про- странственной динамике сообщества амфипод, в котором лидирующие позиции занимают виды - вселенцы из оз. Байкал, распространившиеся через р. Ангару не только вниз, но и вверх по течению р. Енисей. Выявлено 8 видов амфипод, среди них два представителя нативной фауны ( Pontoporeia affinis и Gammarus sp. ) и 6 байкальских эндемиков. На всём протяжении реки среди гаммарид коли- чественно доминировал Gmelinoides fasciatus, второе место занял Philolimnogammarus viridis. Лишь в низовье и дельте Енисея лидирующие позиции перешли к P. affinis - представителю эстуарно- реликтового комплекса организмов, эндемику дельты Енисея. Байкальские эндемики активно засе- лили участок ниже Саяно-Шушенского водохранилища, особенно в зонах массового распростране- ния макрофитов. Основным вектором распространения байкальских эндемиков в Енисее является саморасселение через р. Ангару, замеченное исследователями еще в XIX в. Для G. fasciatus дополни- тельным стимулом роста численности ниже и выше Красноярской ГЭС стала его преднамеренная интродукция в Красноярское водохранилище в конце 1960-х гг. с целью обогащения кормовой базы. Натурализации Ph. viridis на участке Верхнего Енисея способствовала, вероятно, случайная интро- дукция. Наблюдается дивергенция экологических ниш у G. fasciatus и Ph. viridis в Енисее: доминант предпочитает заиленные песчано-галечные биотопы со спокойным скоростным режимом; субдоми- нант склонен к каменисто-галечным грунтам, омываемым быстрым течением. За последние 15 лет возросла плотность и доля амфипод в зообентосе на участке Ангара - Подкаменная Тунгуска. Ре- зультаты гидробиологических исследований оформлены в виде геопространственной базы данных на геопортале, который предоставляет возможности визуализации информации в виде интерактив- ных тематических карт и обеспечивает возможность прямого доступа к данным через картографи- ческие веб-сервисы из современных ГИС.
The results of hydrobiological studies of expeditions, conducted in 2015-2016 in several zones of the Yenisei River from its head to the mouth, are presented. This work deals with the spatial dynamics of the amphipod community, in which the leading positions are occupied by invaders from Baikal. The invaders spread through the river Angara not only downstream, but also upstream the Yenisei. Eight species of amphipods were identified, and there were two representatives of native fauna ( Pontoporeia affinis and Gammarus sp.) and six Baikal endemics among them. Throughout the river, Gmelinoides fasciatus dominated quantitatively among the gammarids, Philolimnogammarus viridis took the second place. Only in the lower reaches and in the delta of the Yenisei the leading positions were surrendered to Pontoporeia affinis - a representative of the estuary-relic complex of organisms. Baikal endemics populated actively the Upper Yenisei section below the Sayano-Shushensky hydroelectric power station (HPS), especially in the areas of massive macrophyte distribution. The main vector of Baikal endemics spreading in the Yenisei is self- colonization through the river Angara, noticed by researchers in the 19th century. For G. fasciatus, its intentional introduction into the Krasnoyarsk Reservoir in the late 1960s with the aim of increasing the food supply was an additional stimulus for the growth of the population below and above the Krasnoyarsk HPS. Naturalization of Ph. viridis in the Upper Yenisei section was probably contributed by an accidental introduction. 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 last 15 years, the density and proportion of crustaceans in the zoobenthos have increased in the Angara - Podkamennaya Tunguska section. The results of hydrobiological studies have been designed in the form of geospatial database in the geoportal, which gives the possibility to visualize information as interactive thematic maps and which provides the direct access to data via web mapping services from the modern GIS software.

Аннотация: В результате многолетних натурных наблюдений определены факты влияния повышенной скорости сброса воды через шлюзы плотины Красноярской ГЭС на динамику фитопланктона р. Енисей ниже плотины. Высказано предположение, что механизм влияния данного фактора заключается в следующем: повышенный сброс воды изменяет температуру воды реки в нижнем бьефе, что в свою очередь влияет на динамику численности фитопланктона. Справедливость данного предположения подтверждается данными 2008-2016 гг. Установлено, что во все рассматриваемые годы, пики численности и биомассы фитопланктона приходятся на июнь за счет диатомовых водорослей, попадающих в нижний бьеф со стоком из верхнего бьефа. Полученные результаты могут быть применены для составления прогнозов динамики фитопланктона в нижнем бьефе в следующие временные периоды.
Using multiyear measurements, we investigated the influence of high flow rates at Krasnoyarsk hydropower station (Krasnoyarsk HPS) on the phytoplankton population of Yenisei River downstream of the dam. We propose the hypothesis that flow rate variations are changing water temperature, which is influencing on phytoplankton dynamics. This hypothesis is verified by measurements of 2008-2016 years. The peaks of number and biomass of phytoplankton were recorded in June in all years in question due to the flow of diatoms from the upstream of the dam. Found relationships could be used for preparation of prognosis of the phytoplankton dynamics downstream of the dam.
