Late glacial and Holocene climate and landscape dynamics in the Valdai Highlands (East European Plain) inferred from lake sediment records
The results of a ground-penetrating radar survey and multiproxy studies of the sediment cores collected from two lakes in the Valdai Highlands (East European Plain) provide new insights into the late glacial and Holocene environmental history of the region situated in the marginal zone of the last Scandinavian ice sheet. The cores were analyzed for organic carbon and nitrogen content, as well as for pollen and diatoms. The chronology of the cores…

Factors in the Formation of Inflation Expectations as Recorded in the Russian National Survey of Consumer Finance
The Bank of Russia uses monthly InFOM survey data to provide a quick estimate of household inflation expectations. A more complete picture of the interrelationships between inflation expectations and the consumer and financial behavior of individuals can be derived from data in the fifth iteration of the Russian National Household Survey of Consumer Finance (Survey of Household Finance — SHF), which for the first time included questions about inf…
Alexander I and the Resignation of M. M. Speransky
This article analyses the historiographical traditions of studying the resignation of M. M. Speransky from the position of Secretary of State in March 1812. Also, the author considers the contradictions in various interpretations regarding the role Emperor Alexander I played in the events and demonstrates the connection of these contradictions with the way in which scholars relied on historical sources to substantiate their concepts. As a result,…
Values in the contemporary Russian society
The report highlights the results of sociological studies devoted to the value system of the Russian society. Value priorities of Russians are considered in dynamics and in comparison with other European countries. In the light of empirical data various stereotypes and autostereotypes of national identity are critically analyzed, including the widespread myths about Russians’ special inclination towards collectivism and the lack of civil society …
Forum 36
this edition of 'Forum' addresses the issues raised when anthropologists attempt to transform their preliminary records into an academic analysis. participants of the 'Forum' answer the following questions: What are the processes by which encounters and conversations with informants become a 'written source'? Is it acceptable to edit field notes? By what processes do these 'written sources' turn into the text of a publication? Is it acceptable to…
Tempering an Enlightened Educator
Among all the educators who cared for him from his early childhood, Alexander I gave a particular honor to only one, the Swiss teacher Frédéric-César de La Harpe (1754–1838), who, invited to teach the French language, was further his instructor in geography, history, arithmetic, and geometry, as well as the foundations of philosophy. This Swiss teacher has been regarded in historical studies as the fortunate “chosen one” by Catherine II, who summ…
Biome changes and their inferred climatic drivers in northern and eastern continental Asia at selected times since 40 cal ka bp
Cross-cultural and transnational identity
After highlighting concepts such as diaspora, acculturation and integration of immigrants, transnational identity, and multiculturalism policy, the authors present results from a case study of 16 Bulgarian emigrants to Canada. The aim is to investigate what changes have taken place in their perception of national and self-identity, and to what extent these changes are dependent on factors such as age, education, reasons for emigration and length …
Comparison of modeled and reconstructed changes in forest cover through the past 8000 years
Reproducing the tree cover changes throughout the Holocene is a challenge for land surface–atmosphere models. Here, results of a transient Holocene simulation of the coupled climate–carbon cycle model, CLIMBER2-LPJ, driven by changes in orbital forcing, are compared with pollen data and pollen-based reconstructions for several regions of Eurasia in terms of changes in tree fraction. The decline in tree fraction in the high latitudes suggested by …
Holocene environments and climate in the Mongolian Altai reconstructed from the Hoton-Nur pollen and diatom records
Environmental Changes in the Mongolian Altai During the Holocene
Based on palynological and diatom analyses of the sediment core from Lake Hoton Nuur situated at 2083 m asl, environmental changes in the Mongolian Altai during the Holocene are described. The results suggest that the Late Pleistocene and Early Holocene (11.5–10.7 ka) climate of that area was cold and arid, and plant associations were of a steppe type. The Middle Holocene (9.3–6.5 ka) climate was warm and humid, resulting in the expansion of fore…
Yr-long records of annual air temperature and precipitation over southern Siberia inferred from Teletskoye Lake sediments
A unique 800-yr-long record of annual temperatures and precipitation over the south of western Siberia has been reconstructed from the bottom sediments of Teletskoye Lake, Altai Mountains using an X-ray fluorescence scanner (XRF) providing 0.1-mm resolution timeseries of elemental composition and X-ray density (XRD). Br content appears to be broadly correlative with mean annual temperature variations because of changes in catchment vegetation pro…
Environmental changes in the northern Altai during the last millennium documented in Lake Teletskoye pollen record
A high-resolution pollen record from Lake Teletskoye documents the climate-related vegetation history of the northern Altai Mountain region during the last millennium. Siberian pine taiga with Scots pine, fir, spruce, and birch dominated the vegetation between ca. AD 1050 and 1100. The climate was similar to modern. In the beginning of the 12th century, birch and shrub alder increased. Lowered pollen concentrations and simultaneous peaks in herbs…
Middle Weichselian environments on western Yamal Peninsula, Kara Sea based on pollen records
Pollen data from two sections from a coastal cliff on the western Yamal Peninsula (69 ° 43.27′N, 66 ° 48.80′E) document the environmental history during the Karginsky (Middle Weichselian) interstadial. Low pollen concentrations, high amounts of redeposited pollen, and relatively high presence of Artemisia pollen characterize sediments deposited at about 33,000 14 C yr B.P. Grass-sedge plant associations with few other herbs occupied the area duri…
Late Quaternary History of the Accumulation Plain North of the Chekanovsky Ridge (Lena Delta, Russia)
Permafrost deposits were studied along the Olenyeksky and the Arinsky distributaries in the western Lena delta using a multidisciplinary approach that included sedimentological, mineralogical, stable-isotope, and paleoecological analyses in order to reconstruct the Late Quaternary landscape and environmental history of this Northeast
Late Pleistocene and Holocene Vegetation and Climate on the Taymyr Lowland, Northern Siberia
Pollen records from perennially frozen sequences provide vegetation and climate reconstruction for the last 48,000 14 C years in the central part of Taymyr Peninsula. Open larch forest with Alnus fruticosa and Betula nana grew during the Kargin (Middle Weichselian) Interstade, ca. 48,000–25,000 14 C yr B.P. The climate was generally warmer and wetter than today. Open steppe-like communities with Artemisia , Poaceae, Asteraceae, and herb tundralik…

Holocene Treeline History and Climate Change Across Northern Eurasia
Radiocarbon-dated macrofossils are used to document Holocene treeline history across northern Russia (including Siberia). Boreal forest development in this region commenced by 10,000 yr B.P. Over most of Russia, forest advanced to or near the current arctic coastline between 9000 and 7000 yr B.P. and retreated to its present position by between 4000 and 3000 yr B.P. Forest establishment and retreat was roughly synchronous across most of northern …
Present‐day and mid‐Holocene biomes reconstructed from pollen and plant macrofossil data from the former Soviet Union and Mongolia
Fossil pollen data supplemented by tree macrofossil records were used to reconstruct the vegetation of the Former Soviet Union and Mongolia at 6000 years. Pollen spectra were assigned to biomes using the plant‐functional‐type method developed by Prentice et al . (1996). Surface pollen data and a modern vegetation map provided a test of the method. This is the first time such a broad‐scale vegetation reconstruction for the greater part of northern…
Lateglacial and early-Holocene environments of Novaya Zemlya and the Kara Sea Region of the Russian Arctic
Pollen and radiocarbon data from Novaya Zemlya and the Kara Sea Region suggest that the hypo thetical Panarctic Ice Sheet (Denton and Hughes, 1981) never existed in this area, at least during the last 16 000 years. Lateglacial tundra environments were slightly cooler and drier than the present ones, but there were also warmer intervals such as the Allerød, which were rather favourable for vegetation development. Better conditions existed during t…
The Ethnic Revolution and Reconstruction of Post-Soviet Space
If Hegel was right and history really is guided by World Reason, then it certainly conceived the processes taking place in our country in such a way that it destroys every concept on which a rational understanding of politics has hitherto been based
