Returning Methods of Rykyu\u27s Drifting Ships in the Qing Dynasty
The communication between Ryukyu・Okinawa and China has a long history. It has been said that the history has begun even at Ming Dynasty. Ryukyu Dynasty were canonized by Chinese king even after Satsuma clan (now Kagoshima Prefecture)\u27s invasion in the beginning of 17 century. The tributary relations between Ryukyu and China had last for 5 centuries until Ryukyu became Okinawa Prefecture by Meiji Japanese government in 1872. The relationship between China and Ryukyu basic were tributary relations. However, the main transportation mean in Ryukyu were by ship, and lots of ship encountered typhoon, lost control of their ship, and finally were drifted to China continent. You can refer to these historical documentation in the book 「Selected documentation of China-Ryukyu relations in Qing Dynasty」 which was public by China First Historical Archives. Lots of ship-drift cases are written in this book from Qianlong era to Guangxu era of Qing Dynasty. Various forms of transportation can be found form those cases. This paper will not focus on tributary ships from Ryukyu, but on the part of rescue and aid from Qing government to those who were drifted from Ryukyu
Structure and evolution of dune massifs in the Vilyui River Basin over the Late Quaternary Period (by the example of the Makhatta and Kysyl-Syr Tukulans)
© 2017, Pleiades Publishing, Ltd. The data of the comprehensive study of deposits of dune sand massifs—the Makhatta and Kysyl-Syr Tukulans—in the Vilyui River Basin (Central Yakutia) are given. We have revealed the structure and preliminarily reconstructed the evolution of tukulans in the Vilyui River basin and the environmental conditions of the surrounding area in the Late Pleistocene–Holocene period (the chronological period of the formation of tukulans) on the basis of lithological and palynological data and 17 radiocarbon datings. It has been revealed that the tukulans should be assigned to eolian deposits formed on sediments of complicated facial structure. We have distinguished four stages in the vegetation evolution within the last 40000-year period and three chronostratigraphical phases in the development of dune massifs
Environmental dynamics of the Baraba forest-steppe (Siberia) over the last 8000 years and their impact on the types of economic life of the population
© 2017 Elsevier LtdThis article offers a reconstruction of the vegetation and climate of the south-western Siberian Baraba forest-steppe area during the last ca. 8000 years. The analysis of palynological data from the sediment core of Lake Bolshie Toroki using quantitative methods has made it possible to reconstruct changes of the dominant types of vegetation and mean July air temperatures. Coniferous forests grew in the vicinity of the lake, and mean July air temperatures were similar to present-day ones between 7.9 and 7.0 kyr BP. The warmest and driest climate occurred at 7.0–5.0 kyr BP. At that time, the region had open steppe landscapes; birch groves began to spread. A cooling trend is seen after 5.5 kyr BP, when forest-steppe began to emerge. Steppe communities started to dominate again after 1.5 kyr BP. Mean July air temperatures lower than now are reconstructed for the period of 1.9–1 kyr BP, and then the temperatures became similar to present-day ones. Comparing the archaeological data on the types of economy of the population which inhabited the Baraba forest-steppe with the data on changes in the natural environment revealed a connection between the gradual transition from hunting and fishing to livestock breeding and the development of forest-steppe landscapes with a decrease in the area covered by forests. The development of the forest-steppe as an ecotonic landscape starting around 5 kyr BP might have contributed to the coexistence of several archaeological cultures with different types of economy on the same territory
Palaeoenvironments during the period of the Neanderthals settlement in Chagyrskaya cave (Altai Mountains, Russia)
© 2015 Elsevier B.V. The Altai Mountains, situated in the middle of Asia, have been inhabited by human groups since prehistoric times. Many Middle Palaeolithic sites (open-air sites and caves) are located in the northwestern part of the Altai Mountains. The uniqueness of this area is in the simultaneous habitation of different human species, such as Neanderthals, Sapiens and Denisovians. The material culture of the Altai Middle Palaeolithic is mostly homogeneous; however, two caves are distinguished from other sites-Okladnikov Cave and the recently studied Chagyrskaya Cave, located in the Charysh River valley. Palaeolithic assemblages from both caves are comparable with the Mousterian industries recorded in certain regions of Eurasia and represent a special variant of the Altai Middle Palaeolithic industries, known as the Sibiryachikha facies. Anthropological data from these caves suggest that the Sibiryachikha variant was associated with Neanderthals. In this study, we reconstruct the palaeoenvironmental conditions of the period of the Neanderthals settlement in the northwestern part of the Altai Mountains based on bioproxies, such as pollen records and large mammal remains. The time of the Neanderthals settlement of Chagyrskaya Cave is attributed to the termination of MIS4 and is characterised by an arid and continental climate. Dry steppe communities were widespread in the Charysh River valley. It is possible that the Chagyrskaya Cave represents a long-term hunting camp where butchering and processing of game animals were carried out. In the following warmer and more humid period the Neanderthals left the cave. This was around the same time when anatomically modern humans began appearing in Western Siberia

Mid-late Holocene environmental history of Kulunda, southern West Siberia: Vegetation, climate and humans
An environmental reconstruction of mid-late Holocene vegetation, climate and lake dynamics was inferred from pollen and diatom records of Lake Big Yarovoe in Kulunda, southern West Siberia. The reconstruction suggests a general prevalence of steppe during the last 4.4 ka. Under a relatively warm and dry climate, open semi-desert and dry steppes with patchy birch forest spread between 4.4 and 3.75 ka BP. The largest development of conifer forest started in Kulunda after 3.75 ka BP. The onset of the Late Holocene is characterised by the dominance of steppe with birch and pine forests in the lowlands and river valleys. After AD 1860, open steppe and semi-desert vegetation with fragmentary birch forest have been dominant in Kulunda, along with a sharp reduction of conifers. These results are in agreement with the general pattern of the Holocene environmental history of the surrounding areas, including the Baraba forest-steppe, Kazakh Upland and Altai Mountains. The penetration of coniferous forest into the Kulunda steppe after 3.75 ka BP was related to its geographical location northwest of the Altai Mountains. The economic activities of the ancient population of Kulunda depended on the environmental changes during the Holocene. © 2012 Elsevier Ltd
New stratigraphic data on the quaternary sediments in the Peschanaya River Valley, Northwestern Altai
© 2017 Siberian Branch of the Russian Academy of Sciences. This paper presents new data on the structure and the lithological, pedological, paleontological, and paleomagnetic features of the Middle and Upper Quaternary sediments in the Peschanaya River valley, the foothills of northwestern Altai. Those horizons contain a loess-soil sequence and sediments relating to two Middle Pleistocene interglacials. On the basis of palynological characteristics of one of the Middle Pleistocene interglacials, the succession of fl oras during the respective stages is reconstructed. The Middle Pleistocene interglacial fl oras of Western Siberia are compared with that reconstructed on the basis of the Karama site, evidencing marked differences. The fl ora around Karama included broad-leaved taxa, which were absent during the Middle Pleistocene interglacials of Western Siberia, when apart from modern arboreal taxa, only cold-resistant broad-leaved ones were present (Tilia, Corylus, Ulmus, and Juglans). The Karama fl ora resembles the last Western Siberian thermophilic fl ora-Barnaul, which existed during the long climatic warming of the Early Pleistocene, corresponding to the Tiglian in northwestern Europe (2.23-1.59 Ma BP). Since the beginning of the Middle Pleistocene, interglacial fl oras of Western Siberia have resembled modern ones. In terms of phytocenotic and palaeoclimatic features, Middle Pleistocene interglacial environments of Western Siberia display a sharp contrast with those of Barnaul and Karama
Paleo-Ecology of the Yedoma Ice Complex on Sobo-Sise Island (Eastern Lena Delta, Siberian Arctic)
Late Pleistocene permafrost of the Yedoma type constitutes a valuable paleo-environmental archive due to the presence of numerous and well-preserved floral and faunal fossils. The study of the fossil Yedoma inventory allows for qualitative and quantitative reconstructions of past ecosystem and climate conditions and variations over time. Here, we present the results of combined paleo-proxy studies including pollen, chironomid, diatom and mammal fossil analyses from a prominent Yedoma cliff on Sobo-Sise Island in the eastern Lena Delta, NE Siberia to complement previous and ongoing paleo-ecological research in western Beringia. The Yedoma Ice Complex (IC) cliff on Sobo-Sise Island (up to 28 m high, 1.7 km long) was continuously sampled at 0.5 m resolution. The entire sequence covers the last about 52 cal kyr BP, but is not continuous as it shows substantial hiatuses at 36–29 cal kyr BP, at 20–17 cal kyr BP and at 15–7 cal kyr BP. The Marine Isotope Stage (MIS) 3 Yedoma IC (52–28 cal kyr BP) pollen spectra show typical features of tundra–steppe vegetation. Green algae remains indicate freshwater conditions. The chironomid assemblages vary considerably in abundance and diversity. Chironomid-based TJuly reconstructions during MIS 3 reveal warmer-than-today TJuly at about 51 cal kyr BP, 46-44 and 41 cal kyr BP. The MIS 2 Yedoma IC (28–15 cal kyr BP) pollen spectra represent tundra-steppe vegetation as during MIS 3, but higher abundance of Artemisia and lower abundances of algae remains indicate drier summer conditions. The chironomid records are poor. The MIS 1 (7–0 cal kyr BP) pollen spectra indicate shrub-tundra vegetation. The chironomid fauna is sparse and not diverse. The chironomid-based TJuly reconstruction supports similar-as-today temperatures at 6.4–4.4 cal kyr BP. Diatoms were recorded only after about 6.4 cal kyr BP. The Sobo-Sise Yedoma record preserves traces of the West Beringian tundra-steppe that maintained the Mammoth fauna including rare evidence for woolly rhinoceros’ presence. Chironomid-based TJuly reconstructions complement previous plant-macrofossil based TJuly of regional MIS 3 records. Our study from the eastern Lena Delta fits into and extends previous paleo-ecological Yedoma studies to characterize Beringian paleo-environments in the Laptev Sea coastal region
