AbstractA newly collected specimen of the enigmatic coleoid genus Longibelus is recorded from lower Turonian strata along the River Shadrinka in Sakhalin (Russian Far East). To date, this is the first record of Late Cretaceous coleoid cephalopods from the island and, in fact, from the entire Pacific coast of the Russian Federation. Lithological characteristics, coupled with published geochemical analyses (δ13C and Corg content), suggest the habitat of this coleoid taxon to have been the middle to outer (i.e. distal) shelf. Its provenance from the stratigraphical level that is known as the Scaphites Event, characterised by a mass occurrence of Scaphites and Yesoites, may be indicative of occasional or marginal overlap in ranges, rather than life in similar habitats. On the basis of lithological features and in view of the extremely rare occurrence of Longibelus in rich ammonite assemblages with clear ecological/bathymetric preferences, the natural habitat of Longibelus may have comprised neritic to mesopelagic zones over distal shelves and slopes.

On the example of Commelina communis L. (Commelinaceae), the typical weed in the south of the Russian Far East, it has been demonstrated that the invasive activity of species significantly increases in conditions of the Pacific monsoon climate. The range of the most important ecological factors (humidity, richness and salinity of soil, the soil texture as well as soil moisture variability) in the Pacific coast is wider than in continental areas. It is quite possible that in the south of Primorye Territory we have the northern part of the Commelina communis natural area of distribution.

Ecological study of coenopopulations of Potentilla fragarioides L. in the south of the Russian Far East resulted in conclusion, that forming of its ecological niche takes place under influence of combination of continental and monsoon climatic factors. Ecological conditions on the Pacific coast of the Russian Far East are more favorable for Potentilla fragarioides than on inland areas, where the main part of the species’ range of geographical distribution is located. Results of the study can be used for phytoindication of biogeographical lines in East Asia as well as for solving of problems of evolution and taxonomy in the Rosaceae Family.

As a result of expeditionary investigations on Iturup Island (southern group of islands of the Kuril archipelago), 61 species of lichens were identified as new to the island, including Porpidia contraponenda and Xylographa rubescens – new to the Russian Far East, and Amandinea coniops and Arthonia dispuncta – new to the South of the Russian Far East. Six species are new to the Sakhalin Region. The difference in species composition of the Sea of Okhotsk coast and the Pacific coast of Iturup Island is briefly discussed.

The article is devoted to the study of individual directions and trends in the development of Russian-Chinese relations in the field of education. Topicality of the research is stipulated by necessity of organizational reforming of higher education system in the direction of perspectives of cooperation between Russia and China that presupposes study and comparative analysis of educational systems of considered countries. The article is devoted to the study of some trends and tendencies in the development of Russian-Chinese relations in the field of education. The specifics of the development of integration of educational space of Russia and China on the example of border regions: Heilongjiang Province and the Far East are considered. The method of comparative analysis was used to identify the specifics of higher education in China and the Russian Federation. Mutual benefit and mutual expediency were indicated as criteria for cooperation of both countries in the field of education. The features of higher education development in Heilongjiang Province and in the Russian Far East were described. An analysis of higher education development in the Russian Far East as assessed by Chinese experts is given. The results of a study by Chinese scholars on the preferences of Russian youth are presented. The key areas of effective joint solution to the problem of training a globally competitive professional are identified. The conclusions can be used in developing plans for cooperation between Russia and China in the sphere of higher education.

Koreans had lived on the southern territory of the modern Russian Far East before the arrival of Russian pathfinders in these lands. Therefore, they are an indigenous population of the modern Primorye region in the Russia, although, in the nineteenth century the number of Koreans was relatively small in the south of the Russian Far East. Russian Koreans supported the October Revolution and the fight of the Red Army against the old regime for several reasons. Bolsheviks put forward two principles of the new government—land for peasants and equality of peoples. These principles found a response in the broad mass of the Korean and Chinese populations in the Far East. After their victory, the Bolsheviks kept their promises. An area for ethnic Koreans, called Posiet, in the territory of the Primorye region was created, and Koreans resided in 28 districts in three areas of the modern Primorye region. A Korean Education College was created in Nikolsk Ussuriysk-city (modern Ussuriysk-city), as well as Korean language schools, a national theater, Korean-Chinese printers and so on. Korean families usually have many children, so the Korean population in Russia grew at a fast pace. This Korean population fell victim to the policies of deportation, which were applied to many of the non-Russian peoples of the Far East under Stalin. For many decades such deportations were denied, and then when admitted, the documentary materials surrounding them were unavailable. However, in the 1980s with the development of greater accessibility to archives held by the Russian Federation, the stories of such difficult historical moments are once again visible and reachable. This Research Note, in particular, explores the archival material that exists in the Gosudarstvennyi Arkhiv Rossiiskoi Federatsii (GARF, Государственный архив Российской Федерации, State Archive of the Russian Federation) relating to the deportation of Koreans of Primorye to Uzbekistan.
