The Caspian Sea is a complicated and open natural geosystem. There are sole mechanisms of geodynamics of global and regional development combining both general energy sources and the energetics of only endogenic or only exogenous processes. Correspondingly, in the occurrence of endogenesis and exogenesis both general, sole mechanisms for them and the specific autonomous mechanisms characteristic for each of the aspect, as well as the complicated combinations of their interactions and interrelations including cascade-energetic systems of various types, levels and power are reflected. Thus, the Caspian phenomenon is a regional reaction to the general changes of global natural geosystem. The research aims studying the areas of modern tensions in the Caspian Sea lithosphere. The main task is the definition of tension state of the lithosphere and its analysis as well. Tectonic structure of the region has been reviewed and seismologic evaluation presented.

Research objective was to identify the specific features of distribution of microelements (zink, manganese, lead, cadmium) in organs and tissues of black-backed shad Alosa kessleri kessleri (Grimm, 1887) and Dolginsky herring Alosa braschnikowii braschnikowii (Borodin, 1904) caught in the Caspian Sea. Accumulated in the tissues and organs of fish in concentrations exceeding the maximum permissible limits, heavy metals pose a danger to human health. Sampling was carried out by the standard techniques, definition of minerals was made by method of atomic and absorbing spectroscopy using an atomic and absorbing spectrometer with electrothermal atomization of MGA-915 MD. The analysis of the obtained data showed that distribution of minerals in the organs and tissues of the studied herring species had a similar pattern: the highest concentrations of minerals were registered in the gills and liver, the smallest - in muscle tissue. In comparison with black-backed shad the organs and tissues of Dolginsky herring had higher concentrations of chemical elements. Zinc has been found to accumulate mainly in the liver; manganese, lead and cadmium - in the gills. Accumulation of zinc, cadmium and lead in the studied bodies and tissues of fishes exceeded acceptable level.

The Impact

For many years, the primary environmental problem of the Caspian Sea has been oil pollution, which is associated both with oil production and transportation, as well as changes in sea level, leading to secondary pollution, river runoff and even seismic activity, which provokes natural oil spills from the bottom of the sea. Abnormal bloom of waters every year becomes more and more long and covers more and more areas, and also occurs in areas where it was not previously observed. However, the current state of the sea, and the trends of its evolution has not been studied enough, which determines the relevance of the solution of the main task of the ongoing Russian Science Foundation Project “Assessing ecological variability of the Caspian Sea in the current century using satellite remote sensing data”. Implementation of the proposed project will assess the relative contribution of each of the sources of pollution of the Caspian Sea, which varies in different periods depending on climatic factors, on the intensity of various hydrodynamic and hydrometeorological processes, on seismic activity and human economic activity. The goal of the project is to assess the changes in the ecological state of the Caspian Sea since the beginning of the current century under the impact of natural and anthropogenic factors. This calls for a detailed analysis of large banks of satellite data acquired over the Caspian Sea from 1999 to 2022 jointly with multi-year hydrometeorological and in situ data. The goal is achievable due to powerful capabilities of the “See the Sea” (STS) information portal developed by the Space Research Institute of the Russian Academy of Sciences (IKI RAS) as part of IKI - Monitoring Center for Collective Use. STS offers oceanographers new and unique tools to work with remote sensing data, enabling comprehensive analysis of data different in physical nature, spatial resolution and time of acquisition.

Eurasia (Cáucaso, Mar Caspio y Asia Central) es un vínculo natural conectando Europa y China en temas comerciales, logísticos, energéticos y de transporte, evitando Rusia, Irán y sanciones. Por más de 25 años, el estatuto legal del Mar Caspio permaneció irresoluto. En 2018, los cinco países ribereños del Mar Caspio adoptaron la Convención sobre el Estatuto Jurídico del Mar Caspio. La Convención se apoya fuertemente en derecho marítimo, evita definir si el Mar Caspio es un lago o un mar, y estipula que, es una cuenca endorreica establecida en mapas específicos. La Convención es pragmática, para conjuntamente explotar recursos submarinos [de hidrocarburos] y colocar ductos sin demarcación fronteriza, permitiendo restricciones ambientales.

Shallow coastal waters of the Volga river is a flooded feeding area for fish juveniles of nonmigratory fish species. There takes place annual downstream migration of fluvial anadromous fish species from spawning grounds of the Volga river to the Northern Caspian Sea. The most important factors determining the number and qualitative characteristics of fry fishes are the level of the Caspian Sea (currently having a tendency to the lowering), hydrological and thermal regimes of the Volga river. Researches were carried out in definite periods of time. In the summer-autumn period of 2012 fry fishes were presented by 19 species (13 of them were commercial species), which belonged to 9 families. The article gives data on all the commercial fish species. In the first decade of July the maximum number of fry fish was registered in the western part of the Volga outfall offshore - in box 247 (19.86 mln specimens/km2), in the eastern part - in box 142 (20.4 mln specimens/km2). The most populous were roach, red-eye, silver bream and bream; size-weight characteristics were better in the areas remoted from the Volga delta. In the third decade of July the quantitative indicators of fry fish on these areas decreased, size-weight characteristics greatly increased. In the second decade of October in the western part of the seaside there were registered increased pre-wintering concentrations of fish juveniles, their qualitative indicators increased, which is evidence to favorable feeding conditions in 2012.

The article specifies the type locality of the Steppe Ribbon Racer. The holotype Coluber (Taphrometopon) lineolatus Brandt, 1838 is stored in the reptile collection of the Zoological Institute of the Russian Academy of Sciences (ZISP No 2042). Literature sources provide different information about the type locality. A mistake has been made in the title of the work with the original species description: the western coast of the sea was indicated instead of the eastern one. The place of capture was indicated as “M. Caspium” (Caspian Sea) on the label and in the reptile inventory book of the Zoological Museum of the Academy of Sciences. The specimen was sent to the museum by G.S. Karelin. The “1842” indicated on the labels and in the inventory book cannot be the year of capture of the type specimen, just as the “1837” indicated by A.M. Nikolsky. In 1837, Karelin was in Saint Petersburg and in 1842 in Siberia. Most likely, 1837 is the year when the collection arrived at the Museum, and 1842 is the year when the information about the specimen was recorded in the inventory book (catalog) of the Zoological Museum of the Academy of Sciences. In our opinion, the holotype was caught in 1932. From Karelin’s travel notes of the expedition to the Caspian Sea in 1832, follows that the snake was recorded in two regions adjacent to the eastern coast of the Caspian Sea – Ungoza Mountain (“Mangyshlak Mountains”) and site of the Western Chink of Ustyurt between Zhamanairakty and Kyzyltas Mountains (inclusive) on the northeast coast of Kaydak Sor (“Misty Mountains”). In our article, Karelin’s route to the northeastern coast of the Caspian Sea in 1832 and photographs of these localities are given. The type locality of Psammophis lineolatus (Brandt, 1838) should be restricted to the Mangystau Region of the Kazakhstan: Ungoza Mountain south of Sarytash Gulf, Mangystau (Mangyshlak) Penninsula (44°26´ N, 51°12´ E).

Transparency And Accountability

The article is devoted to issues of ensuring transparency and ac- countability of authorities in the conditions of participatory democracy (democ- racy of participation). It is argued that the public should be guaranteed not only the right for access to information but also the prerequisites for expanding its par- ticipation in state governance. These prerequisites include: the adoption of clearly measurable macroeconomic and social goals and the provision of control of the processes of their compliance with the government by citizens of the country; ex- tension of the circle of subjects of legislative initiative due to realization of such rights by citizens and their groups; legislative definition of the forms of citizens’ participation in making publicly significant decisions, design of relevant orders and procedures, in particular participation in local referendum; outlining methods and procedures for taking into account social thought when making socially im- portant decisions. The need to disclose information about resources that are used by authorities to realize the goals is proved as well as key performance indicators that can be monitored by every citizen; the efforts made by governments of coun- tries to achieve these goals. It was noted that transparency in the conditions of representative democracy in its worst forms in a society where ignorance of the thought of society and its individual members is ignored does not in fact fulfill its main task — to establish an effective dialogue between the authorities and so- ciety. There is a distortion of the essence of transparency: instead of being heard, society is being asked to be informed — and passively accept the facts presented as due. In fact, transparency and accountability in this case are not instruments for the achievement of democracy in public administration, but by the form of a tacit agreement between the subjects of power and people, where the latter passes the participation of an “informed observer”.
