Abstract
Mayamaea arida (Bock) Lange-Bertalot is a rare species, previously recorded from four locations in Europe only. The aim of this study is to report additional molecular, phenotypic and geographic data on M. arida. The strain of this species was isolated from the soil sample collected on 04.08.2018 in Iturup Island (Sakhalin Region, Russia) in Haplic Cambisol. The strain was identified using light and scanning electron microscopy. Phylogenetic analysis revealed that the M. arida was a member of the strongly supported Mayamaea generic clade and resolved as a basal lineage in the subclade comprised by M. atomus and M. terrestris. New data on partial rbcL plastid gene, chloroplasts morphology and nucleus, lower limit of the cell length, higher number of striae in 10 urn, shape index (length/width), teratological forms and distribution of species are presented.
Ecological aspect of the development of soil-forming processes at the post-technogenic stage
Authors: Podurets O I , Osintseva M A 
Published: December 2021

Abstract
The relevance of the study is caused by the problem of the global anthropogenic transformation of natural landscapes in Kuzbass as a result of the development of mining. The rate of reclamation of disturbed lands lags behind the rate and scale of their formation, and most of the territory is self-recovering. This paper is aimed at studying the ecological conditions of the natural environment and technogenic factors affecting the dynamics of soil-forming processes and the formation of phytocenoses in disturbed territories, which differ in the way of formation at the technogenic stage. For the first time, some physicochemical parameters of technozems were obtained. Like ebriozems, they are formed in the post-technogenic phase of the development of a technogenic landscape under the conditions of its self-growth. The similarities and differences in the properties of technozems and ebriozems formed in the same natural and climatic conditions of the southern forest-steppe zone of Kuzbass have been revealed. It was found that the rate of their transformation, expressed in the formation of the soil profile, depends on the conditions of the relief and underlying rocks created at the technogenic stage. The presence of a preserved layer of potentially fertile rocks and the absence of slope surfaces led to the formation of the frontal soil and vegetation cover of the technozem; under other conditions, the formation of soils and plant groups occurs fragmentarily, which leads to the asynchronous development of the functions and modes of the technogenic landscape.

Published: December 2021

Abstract
This research is based on the multi-year data on the distribution of organochlorine pesticides of the DDT group in the water of the coastal Black Sea areas of Crimea, obtained in expeditions of the “Professor Vodyanitsky” research vessel from 1999 to 2020. Study of content of DDT and its metabolites (DDTs) in the blubber of three species of Black Sea cetaceans that were astrand on the Black Sea coast from the 1980s to the 2020s was grounded on own and literature data. While there was an overall significant variability in ∑DDT content during the study period, there was a significant downward trend in their concentrations in the water of coastal areas of Crimea. Despite the significantly decreased DDTs pollution of the habitat of the Black Sea marine mammals over the last 10 years, high concentrations of DDTs were accumulated in their blubber, the maximum value of the sum of DDTs concentrations reached (163 µg/g of lipids) in the blubber of adult depleted bottlenose dolphin. The minimum concentrations were determined in the blubber of a newborn harbour porpoise female. In blubber samples up to 70% was of DDE, DDD - from 21 to 24%, and the concentration of the initial DDT varied from 6 to 14%. Based on the analysis of own and literature data, it is assumed that in the modern period, as compared to the 1990s, there is a downward trend in the content of the DDTs in the blubber of Black Sea cetaceans.
A bioassay of the toxic effects of aluminum chloride and aluminum sulfate using Auloforus (Dero furcata)
Authors: Ivanova I , Popov A , Chukhno A , Kovalkova S 
Published: December 2021

Abstract
The analysis of the toxicity of aluminum salts is determined by the fact that aluminum cation is contained in drinking water, artificial dyes and additives, medicines, vaccines, aerosols, and there is also a correlation between the concentration of aluminum ion in brain tissues and clinical manifestations of Alzheimer’s disease. The article presents the results of biotesting the toxic effects of aluminum chloride and sulfate using Aulophorus (Dero furcata). Currently, the methods of bioassay do not have a generally recognized and standardized system of biological analysis, there are no unambiguous requirements that an indicator system should meet. These worms are a biotest object, because its reaction to the environment can be traced by its creation of conglomerates. The behavior of Auloforus in the experiment depends on the concentration, the time spent in aluminum solutions, as well as on the specific salt. When comparing the dynamics of the behavior of Auloforus in experimental samples of aluminum solutions, we established toxic concentrations. It was found that aluminum chloride salts have a less toxic effect than aluminum sulfate.

Published: December 2021

Abstract
Climate change is one of the greatest environmental issues of our time and involves complex interactions and changing likelihoods of diverse impacts. Individuals, communities and organizations have, through time, developed adaptive capacities to climate change impacts. This paper assesses by reviewing existing literature on the adaptation of the low carbon model to climate change by rural farming households in developing countries. It has identified the social, economic and environmental impacts of climate change from a vast review of the literature. The commonly used low carbon assessment models, from rural farming household’s point of view, have been identified as agricultural and economic models. It was found that farming practices were common and easy used adaptation models to low carbon situations. It was further indicated that complex economic models – partial equilibrium and general equilibrium - were used to assess the efficiency of adaptation options. Marker failures, policy failures and climate uncertainties were the main barriers to the low carbon adaption model. Although not easy, some remedies for adaptation barriers have been identified as policy reforms, government intervention, introducing various adaptation approaches such as early warning systems, disaster risk management, climate-smart agriculture and insurance systems.

Abstract
In the complex of socio-economic and environmental problems, infrastructure provision is becoming a cornerstone. A feature of remote areas is the inconsistency in understanding the vital need for access to modern infrastructure (primarily, to transport opportunities) and the costs associated with this access. On the one hand, the transport infrastructure in the region contributes to the efficient use of the economic potential of the region. On the other hand, isolation from the outside world with restricting existing traffic flows and rejecting new transport projects may be the local population’s own choice. Industrial development is the main driving force in the development of the transport infrastructure of the territories. In this work, the following study areas were selected as model areas for the study of the mutual influence of mining enterprises and the development of transport infrastructure - Todzhinsky Kozhuun of the Republic of Tyva and Okinsky District of the Republic of Buryatia. Methods of comparative geographical and statistical analysis and data generalization, network and problem approaches, in-depth and group interviews of local residents were used. The results of the analysis of publicly available data on the development and maintenance of specific transport arteries and materials of original field studies are presented.
Environmental assessment of the estimated dredging volumes on the Ob River
Authors: Bik Y , Buchelnikov M , Kofeeva V 
Published: December 2021

Abstract
The object of the study is the impact of dredging in the Ob riverbed on individual components of the environment, in particular, ichthyofauna. The volumes of transit and capital dredging in the river channel on the crossing sections that are difficult for navigation have been determined and substantiated. To calculate the damage, a method to determine the loss of ichthyofauna was used, taking into account the death of benthic and planktonic organisms in turbidity plumes and on the bottom areas subjected to development by dredgers and buried under dumped fills. It has been established that the greatest losses of ichthyomass will occur in the sections of the Upper Ob (up to the Novosibirsk reservoir) and the Middle Ob (up to the mouth of the Tom River), which is explained by the presence of numerous crossovers that impede navigation and require constant dredging. In the Lower Ob, the negative impact on benthos, plankton and ichthyofauna will be insignificant due to the small number of small crossovers. The volumes of dredging in the fairway required to maintain guaranteed depths and dimensions have a certain environmental load, the level of which is not critical for the ecosystems of a large river. However, when creating large-scale capital bypass channels, it can increase sharply in certain years. By reducing the load, a stable shipping lane can be created and the frequency of dredging operations at each of the crossover sections can be reduced. The advantages and disadvantages of the used damage assessment method are noted.

Authors: Lukin S V , Zhuykov D V 
Published: December 2021

Abstract
Studies were carried out on the territory of the steppe and forest-steppe zones of the Central Black Earth Region of the Russian Federation. The objects of research were the soil of nature reserves and arable chernozems that were not touched by agricultural activity, typical and common, the vegetation cover of natural biocenoses and agroecosystems, and organic fertilizers. The studies found that the background content of mobile sulfur in virgin soils is at a low level: 2.31 mg/kg - in a typical chernozem and 1.83 mg/kg - in an ordinary chernozem. According to agrochemical monitoring of arable soils carried out during 2015-2018, an increase in the weighted average content of mobile sulfur by 0.7 mg/kg to 3.3 mg/kg was established, compared to 2005-2009. However, the proportion of soils low on this element remains quite high - 90.3%. The main source of sulfur supply to the soils of agroecosystems (7.52 kg/ha) are organic fertilizers, the doses of which in 2015-2018 increased to 8.1 tons/ha. The average sulfur content in the steppe mixture of herbs of reserves is 0.3-0.4 mg/kg. The highest sulfur content among perennial legumes is clover (0.61%) and alfalfa (0.60%), and among legumes - soybeans, containing 0.34% of the element in grain and 0.21% - in straw.

Published: December 2021

Abstract
The main way to understand variability of any spatial data using remote sensing is calculating spectral indices. For now, some difficulties have receiving water surface temperature due to specific properties for satellite sensors and low spatial resolution. The main sources of receiving salinity data are remote sensing data from ESA SMOS, NASA Aquarius and SMAP satellites. Using different machine learning algorithms, we can get models or equations, representing dependency between studied environmental variable and different spectral channels of remote monitoring data. After receiving and collecting remote sensing data in database this system uses machine learning algorithms to find dependency between collected field data and different spectral bands of the remote sensing data. Our goal was to form an analytical system based on remote sensors and machine learning algorithm to analyse, predict and evaluate water ecosystems for fisheries and environmental protection.

Abstract
In the article, the authors consider the features of the studied territory of traditional nature management in order to develop recommendations for optimizing the system of local environmental monitoring. The existing local regulations and requirements for the development and maintenance of local environmental monitoring systems are analyzed using the example of the Khanty-Mansiysk Autonomous Okrug. The ecological efficiency of the local ecological monitoring systems has been proved and recommendations have been developed for the unification of this system. The information obtained in the course of the study showed that monitoring in territories of traditional nature use is a necessary procedure for the purposes of effective management of these territories. Finding a balance between the economic activities of industrial companies and the traditional use of natural resources by the indigenous small-numbered peoples of the North constantly arouses interest in the scientific community, since the territories of traditional nature use are quite vulnerable and require special measures for their use and protection.

Authors: Derevenskaya O Y 
Published: December 2021

Abstract
Ponds rehabilitation projects for the purpose of eco - rehabilitation following significant anthropogenic impacts or degradation are becoming more frequent but not always successful. Therefore, the experience of the restoration of the Lebyazhye system lakes in Kazan city (Russia) is interesting. Previously, the lake system used to consist of four ponds, but due to water catchment area reduction, the area of the lake system also decreased, and only one lake remained. The restoration of the Lebyazhye system lakes was carried out in 2017 and included the deepening of the basin of the Bolshoe and Svetloe Lebyazhye lakes to 4 m, the sealing of the bed of future ponds with bentonite mats, supplying water from Izumrudnoye lake through a pressure water conduit and filling the basin of the lakes with water. The research is devoted to the study of the restoration of zooplankton communities in the Lebyazhye system lakes. For this purpose, the indicators of zooplankton communities before and after eco-rehabilitation measures were compared. After the implementation of eco-rehabilitation measures, significant changes in environmental parameters were observed: the salinity of water decreased, the oxygen content in the water, pH increased. In zooplankton communities, the species richness and diversity increased, new species appeared, as well as those that lived in the lake system earlier before eco-rehabilitation measures were taken.
Ecological aspects of bivalve adaptation to salinity fluctuations on the example of Anadara Kagoshimensis
Authors: Kladchenko E , Andreyeva A , Rychkova V 
Published: December 2021

AbstractImpact of salinity stress on the ark clam (Anadara kagoshimensis (Tokunaga, 1906)) hemocyte functions were investigated using flow cytometry and light scattering technique. In control group water salinity was 18 ppm and experimental groups were carried at 14 ppm, 8 ppm, 35 ppm and 45 ppm. Hemolymph osmolarity decreased at hypoosmotic conditions and increased after hyperosmotic treatment. Osmotic stress induced changes in osmotic fragility of the ark clam hemocytes. Salinity 14 ppm did not affect the functional parameters of hemocytes. Incubation of ark clams at salinity and 35 ppm did not influence on the mitochondrial membrane potential of hemocytes but led to a decrease in hemocyte reactive oxygen species (ROS) production by 30 % compared to control. An increase in water salinity to 45 ppm and its decrease to 8 ppm induced substantial changes in the ROS production and mitochondrial membrane potential of hemocytes. Hyposalinity (8 ppm) led to an increase in ROS production by hemocytes (up to 2.4 times) and mitochondrial membrane potential (up to 1.3 times). An increase of salinity level from 18 ppm to 45 ppm decreased the total ability of hemocytes to produce ROS by 11% and increased mitochondrial potential of hemocytes by 150%.
Ecological features of the accumulation of carotenoids in the Black Sea molluscs
Authors: Borodina A , Zadorozhny P 
Published: December 2021

Abstract
The analysis of carotenoids of three species of bivalve filter feeding molluscs: Cerastoderma glaucum, Chamelea galina and Polititapis aureus, inhabiting the same ecotope, in the innermost part of the bay of the Sevastopol city, has been carried out. The dynamics of total carotenoid content (TCC) in these species had shown during 4 seasons of the year. The composition of carotenoids is presented in C. glaucum and P. aureus by 8 carotenoids, and Ch. galina - 11 carotenoids. However, in P. aureus, only 75% of the TCC were analyzed. The TCC of all 3 species of molluscs contained to 75% of the total (identical) carotenoids. Each species of molluscs retained their specific carotenoids. Comparative analysis of carotenoids between Black Sea mollusks and their species analogues from other regions of the World Ocean showed differences in the composition of carotenoids. Thus, changing environmental conditions of the same type of filter-feeding mollusk lead to the implementation of adaptation mechanisms in the body, as a result of which the qualitative composition of carotenoids changes.

Published: December 2021

Abstract

Mya arenaria are large bivalve mollusks burrowing into the ground. Mollusks are widespread in the northern hemisphere. The growth patterns of M. arenaria were studied in the arctic part of the species’ geographic range. As a result of the research, it was revealed that the mollusks from the Severnaya Inlet of the Kandalaksha Bay of the White Sea have the highest growth rate. The limiting shell length is L∞=174.7 mm, and the rate of growth retardation is k=0.0518 year–1. The mollusks from the Yarnishnaya Inlet of the Barents Sea have the lowest growth rates L∞=84.27 mm, and the rate of growth retardation is k=0.0721 year-1. A positive correlation was found between the nature of the soil and the limiting shell length of mollusks (r = 0.94).
