The author considers some fungi species which have been recorded in the Jewish Autonomous region (southern part of the Russian Far East) only once. These species can be regarded as little-known either in the Russian Far East, or in the entire territory of Russia. The Bryoperdon acuminatum is only the second confirmed finding in the Russian Far East – partly, perhaps, due to the inconspicuousness of its mature fruitbodies; Entoloma ameides is a fairly well recognizable species with a specific pleasant smell of fruitbodies; Gloeostereum incarnatum is a species with large, conspicuous fruitbodies of a peculiar color and texture, also known both in the Primorsky and the Khabarovsk Territories; Leucoagaricus lateritiopurpureus and L. rubrobrunneus are litter saprotrophs with small fruitbodies – previously found, described and recorded only in the southern part of the Primorsky Territory; Limacellopsis guttata is a species confined to areas of deciduous forests with a thick layer of litter, and it is also known in the Russian Far East by single findings at the Amur Region and Khabarovsk Territory; Neoboletus erythropus is a mycorrhizal species growing in broad-leaved forests; Porodisculus pendulus was found for the first time in the Russian Far East floodplain of the Amur river on oak wood substrate, and later in the Amur Region in a similar habitat on the same substrate; Russula amoena was found in the Russian Far East only once, in light forests typical of the Middle Amur Lowland; Tricholoma frondosae is the only record of the species in the Russian Far East so far. The author provides the found fruitbodies photos. The material may be useful to mycologists in their field work.

On the basis of a deterministic-probabilistic model for assessing the occurrence of fires of interconnected vegetation areas according to natural and anthropogenic conditions, a geoinformation system has been developed, consisting of a database and blocks for access to open data and searching adjacent neighborhoods, calculating meteorological and anthropogenic fire danger, and for regulating forest protection measures. Databases contain information about vegetation fires, data from hydrometeorological stations and anthropogenic sources. To account for the influence of interconnected areas on fire danger, a complex with an algorithm for searching vegetation quarters was used and its integration with the blocks of the geoinformation system was carried out. The architecture of the geoinformation system is based on a three-tier distribution, including a database server with API access support, an application broker and an application for visualization of calculation results. The API server stores structured data from open sources accessible via application exchange protocols, the application broker contains functions for data collection, calculation of indicators and their visualization in third-party applications. To build electronic maps, open data from the OpenStreetMap resource for the districts of the Russian Federation in the WSG 84 cartographic projection was used. Individual vegetation fires were obtained according to MODIS satellite monitoring data from 2013 to 2022. The attribute data of fires contain the identifier, the coordinates of the center, the area of ignition, the date of detection and elimination, the forest and non-forest area. Verification of the system is planned to be carried out in the fire season 2023–2024.

Photo monitoring with the help of camera traps has proven itself as one of the key methods in the study of the Amur tiger, which allows obtaining up-to-date information on the population condition, its number, and its sex and age structure. In the Bastak Nature Reserve, 50 camera traps are installed and operate year-round. They form trapping stations of paired cameras recording a tiger on both sides and correctly identifying it. Based on the obtained photo and video materials for 2022, the authors have analyzed the Amur tiger visits to trapping stations in the cluster «Central» of the reserve Bastak. With the interpolation module, the data analysis was carried out in the QGIS program, which allowed to determine a place most visited by Amur tigers. The site is located in the upper reaches of the Ikura River (Rocky Hill ridge), where adults are most often recorded. A male Bastak (20 meetings), females Cinderella (10 meetings) and Tala (8 meetings) were identified and reflected on the GIS layer. The male named Bastak is regularly noted in the upper reaches of the river with the same name. According to the study results, there is a need in increase of the trapping stations number. It is created the stations location model to fully embrace the Amur tiger habitat by photo monitoring in the cluster “Central” and its protection zone. The data obtained makes the basis for a further study of the predator’s food supply, for getting up-to-date information about the habitat areas and peculiarities of the Amur tiger daily and seasonal activity in the Bastak Reserve and adjacent territories.

The accumulated knowledge about the structure of a substance makes it possible to control its properties, including the purposeful selection of raw materials and materials for its creation, and vice versa, based on the natural or artificial material composition, predict its physical and chemical properties. This approach allows choosing a replacement for rare or even scarce types of mineral raw materials to produce a particular product. The analysis of literature data and sources, a comparative analysis of the Middle Amur Lowland loess-like rocks chemical composition, and one of the white porcelain recipes for the manufacture of laboratory glassware showed a high degree of their similarity. In this connection, it is proposed to consider loess-like loams as one of the porcelain stone types. At the same time, there are some differences – an increased content of coloring oxides in loess-like loam: TiO2 twice and Fe2O3 more than 10 times; reduced content of SiO2 and Al2O3 by 6–7%; the content of CaO and MgO is twice as high as in porcelain; Na2O is 1,7 less, and K2O is 3.4 more than in porcelain. Evaluating loess-like loams as a kind of porcelain stone, we can conclude that the rocks are alkaline according to the total content of alkalis (Na2O + K2O) - more than 3%. Potassium module (K2O/Na2O) is 1,54 – i.e. the rocks are suitable for the manufacture of porcelain. Thus, loess-like rocks are potentially applicable to use them as a corrective raw material in the production of ceramic masses, including coarse building ceramics, colored porcelain and porcelain-like products, with appropriate adjustment of chemical and granulometric compositions. At the same time, in order to clarify the proposed loess-like rocks options feasibility, it is necessary to conduct additional manufacture and technological tests.

By the law of the Jewish Autonomous region, May 28 is recognized as one of the official memorable dates in the history of the region. It was on this day in 1858 in the Chinese city of Aigun that the Aigun Treaty, a historical document on the delimitation of Russia and China possessions, was signed. The agreement is a legal justification for the annexation of the lands lying on the left bank of the Amur to the Russian Empire, as well as Primorye. The history of the Jewish Autonomous region is an integral part of the Russian state general history concerning the development of Siberia and the Far East lands by Russians. Its initial stage should be considered 1581, when the pioneer squad headed Ermak Timofeevich marched from the banks of the Kama River to the east, which contributed to the discovery and annexation of new rich lands located beyond the mountains of the Urals to the Russian state. The subsequent advance of Russian explorers from the Ob to the Yenisei, from the Yenisei to the Lena and further to the Pacific Ocean, later resulted in the domination of Russia on the Amur and in the Amur lands annexation. The movement to Siberia and the Far East served as a source of the state treasury deficit replenishment, provided trade ties with the peoples living on these lands, as well as the opportunity to break through the isolation and blockade in the Russian state in the west and southwest. However, the Russian stay on the Amur was short-lived and was interrupted in the middle of the XVII century by military actions by well-armed troops of the Qing Empire. Unable to transfer large military forces to the Amur region, in 1689 Russia was forced to sign the Treaty of Nerchinsk, according to which the Russians left the left-bank Amur region for more than a century and a half. But the efforts and sacrifices of the XVII century pioneers in the Amur region were not in vain. They became a prologue for the subsequent restoration and consolidation by the Russian state of its territorial and political positions.
根据犹太自治区的法律，5月28日被认定为该地区历史上的官方纪念日期之一。1858年的今天，在中国的爱岗市签署了《爱岗条约》，这是划界俄罗斯和中国领土的历史文件。该协议为俄罗斯帝国吞并位于阿穆尔河左岸的土地以及滨海边疆区提供了法律依据。犹太自治区的历史是俄罗斯国家关于俄罗斯人开发西伯利亚和远东土地的通史的一个组成部分。它的初始阶段应该被认为是1581年，当时以Ermak Timofeevich为首的先锋队从卡马河(Kama River)河岸向东行进，这有助于发现和吞并乌拉尔山脉以外的新的肥沃土地。随后，俄罗斯探险者从鄂毕河到叶尼塞河，从叶尼塞河到勒拿河，再到太平洋，最终导致了俄罗斯对阿穆尔河的统治和对阿穆尔河土地的吞并。向西伯利亚和远东的迁移是国家财政赤字的一个补充来源，提供了与生活在这些土地上的人民的贸易联系，以及打破俄罗斯国家在西部和西南部的孤立和封锁的机会。然而，俄国人在阿穆尔河上的停留是短暂的，并在十七世纪中叶被装备精良的清朝军队的军事行动所打断。由于无法将大量军事力量转移到阿穆尔河地区，1689年，俄罗斯被迫签署了《尼布钦斯克条约》(Treaty of Nerchinsk)，根据该条约，俄罗斯人离开阿穆尔河左岸地区超过一个半世纪。但17世纪阿穆尔河地区拓荒者的努力和牺牲并没有白费。它们成为俄罗斯随后恢复和巩固其领土和政治地位的序幕。

The Mongolian oak Quercus mongolica Fisch. ex Ledeb. along with the Korean pine, Pinus koraiensis Siebold et Zuss form the ecosystem integrity basis at the Bastak Reserve. The study of these species productivity is important and relevant. Currently, a number of articles have been published on the Korean pine nut productivity in the protected area. However, the information concerning the Mongolian oak yield is available only in the Annals of Nature. This paper presents the assessment data on the Mongolian oak acorns yield as a fodder base for a number of wild animals being the nutrition for the Amur tiger. This species productivity monitoring has been carried out at Bastak Nature Reserve since 2015. However, the first acorn harvest was obtained only in 2017. The assessment is made on permanent transects in different areas of the reserve. The research shows that monitoring of the Mongolian oak harvest in the Bastak reserve is carried out irregularly. The productive and lean years alternation trend has not been determined yet, unlike in the Lazovsky Reserve. Perhaps, because of a short monitoring period. The Mongolian oak acorns yield is significantly influenced by the weather conditions, primarily, the absence of rainy days during the flowering period. It is noted that in the absence of Mongolian oak acorns yield there is a good harvest of pine nuts partially compensating the absence of acorns as a nutrition for ungulates. However, maintaining a stable density of ungulates needs certain bio-technical measures, such as feeding grounds.

In the tectonic structure of the Earth, formed by rotational processes, a stable regmatic network (tectonic framework) and structures of the central type (ring, vortex, etc.) are of the main importance. Lithosphere plates are global vortex systems arisen as a result of the tectonic flow of masses in the state of a viscous fluid. Eddy structures are tectonic complexes in which the results of vertical and horizontal tectonic movements combination are captured and can be recorded by direct geological observations. In the Western Pacific Ocean, it is noteworthy a series of structures in the form of a system of marginal seas representing the Western Pacific continent-ocean transition zone. The tectonic evolution of the West Pacific region is the formation of lithosphere eddies series in the continent-ocean junction zone. It is associated with the Earth mantle and upper shells (tectonospheres) energy interaction, due to the unstable regime of the planet’s rotational dynamics. Of particular interest are the global shear zones and eddies of the lithosphere formed as a result of horizontal and vertical tectonic movements combination. It is shown that: 1) all tectonic dislocations contain both horizontal and vertical components of the movement velocity, the former dominating in the structure formation of the region; 2) their interaction outcome is vortex and other nonlinear deformations of the lithosphere, which constitute the main type of structural elements of the region; 3) they are often accompanied by the tectonosphere magmatic activation in the form of convective movements and / or plumes “floating”; 4) the Western Pacific marginal-sea depressions are the funnels of convective cells, which formed lithosphere eddies under the conditions of a shift in the interacting lithosphere plates velocities.

Lithosphere plates are global vortex systems arisen as a result of the tectonic flow of masses in the state of a viscous fluid. Eddy structures are tectonic complexes in which the results of vertical and horizontal tectonic movements combination are captured and can be recorded by direct geological observations. In the Western Pacific Ocean, it is noteworthy a series of structures in the form of a system of marginal seas representing the Western Pacific continent-ocean transition zone. The tectonic evolution of the West Pacific region is the formation of lithosphere eddies series in the continent-ocean junction zone. It is associated with the Earth mantle and upper shells (tectonospheres) energy interaction, due to the unstable regime of the planet’s rotational dynamics.
