Continental-scale estimates of vegetation cover, including land-surface properties and biogeographic trends, reflect the response plant species to climate change over past millennia. These can help assess effectiveness simulations using forward inverse modelling approaches. With advent transient contiguous time-slice palaeoclimate simulations, datasets with similar temporal qualities are desirable. We collated fossil pollen records for period 21,000–0 cal yr BP (kyr BP; calibrated ages)...
Abstract. The Eurasian (née European) Modern Pollen Database (EMPD) was established in 2013 to provide a public database of high-quality modern pollen surface samples help support studies past climate, land cover, and use using fossil pollen. EMPD is part of, complementary to, the European (EPD) which contains data on found Late Quaternary sedimentary archives throughout region. EPD turn rapidly growing Neotoma database, now primary home for global palaeoecological data. This paper describes...
Abstract. Sedimentary charcoal records are widely used to reconstruct regional changes in fire regimes through time the geological past. Existing global compilations not geographically comprehensive and do provide consistent metadata for all sites. Furthermore, age models provided these harmonised many based on older calibrations of radiocarbon ages. These issues limit use existing research into past regimes. Here, we present an expanded database records, accompanied by new recalibration...
Two quantitative methods were used to reconstruct paleoenvironments and vegetation in the Altai–Sayan mountains, Central Asia, during Holocene. The 'biomization' method of Prentice et al (1996 Clim. Dyn. 12 185–96), applied surface pollen record, worked fairly well reconstructions current vegetation. Applying this fossil data, we reconstructed site paleovegetation. Our montane bioclimatic model, MontBioCliM, was inversely convert paleovegetation into paleoclimates. differences between paleo...
Abstract. Different biological proxies such as pollen, cysts, and diatoms were identified quantified in the upper part of a Belukha ice core from Russian Altai. The glacier collected 2001 (4062 m a.s.l., 49°48' N, 86°34' E) was analyzed with annual resolution period 1964–2000. Daily data frequency synoptic patterns observed Northern Hemisphere along daily precipitation have been used to identify predominant atmospheric circulations (elementary circulating mechanisms, or ECMs) generating...
Abstract Rapid permafrost degradation and peatland expansion occurred in Eurasia during the Early Holocene may be analogous to region’s response anthropogenic warming. Here we present a 230 Th-dated, multiproxy speleothem record with subdecadal sampling resolution from Kyok-Tash Cave, at modern margin northern Altai Mountains, southwestern Siberia. Stalagmite K4, covering period 11,400 8,900 years before present, indicates an absence of stable within three centuries Younger Dryas...
Southern Siberia is characterized by complex climatic and vegetation patterns, the late‐Quaternary evolution of climate in this vast region still poorly understood. This study uses pollen, spores, testate amoebae plant macrofossils to characterize environmental changes at Bezrybnoe Mire (Western Sayan Mountains, southern Central Siberia). Pollen data indicate permanent forest cover during Late Holocene subtle variations abundances dominant taxa ( Pinus sibirica , Abies Larix sylvestris...
Abstract To investigate long-term relationships between climate, vegetation, landscape geochemistry and fires in the boreal forest zone of Western Siberia, a sediment core 345 cm was collected from Shchuchye Lake (located south taiga southeast part West Siberian plain) investigated by spore-pollen, radiocarbon, LOI charcoal analyses. Quantitative palaeoclimate reconstructed based on pollen data. Investigation revealed 13.2 cal ka history landscapes fires. In dry climate Late Glacial,...
Prehistoric and early historic human cultures are known to be closely connected dependent on their natural environments. We test the hypothesis that climate change influenced means of subsistence ancient tribes favored agricultural or cattle herding economic strategies. Our study area is Khakass–Minusinsk Hollow, located in foothills Sayan Mountains, south-central Siberia, which was, for a few millennia, buffer zone migrations across Great Eurasian Steppe. Three different methods (the...
This study presents high-resolution multi-proxy biological and geochemical records in an 82-cm sediment core from Manzherok Lake located forest-steppe zone on western piedmonts of Altai Mountain, Russia. Based 210Pb dating 48 AMS 14C dates as well pollen data proxies, detailed lake history local climatic changes over the 1500 years are obtained. Prior to Medieval Warm Period (MWP), had high productivity under stable moderately wet warm conditions. During 1150~1070 yr BP, strong surface...
The study of climatic dynamics that affects the territories with main concentration agricultural production in Siberia is complicated by lack suffciently long-term instrumental observations changes parameters. Investigations such natural archives as lake and peat sediments, which are widespread Western help to solve this problem. Paleopalynological studies, accompanied results additional paleoecological research methods, namely multi proxy provide valuable information on biogeocoenotic cover...
Siberia and Central Asia are located at middle to high latitudes, encompassing a large landlocked area of the Eurasian continent vast tracts permafrost, which sensitive global climate change. Here, we investigated data from 15 Global Network Isotopes in Precipitation (GNIP) stations clarify relationship between precipitation δ18O (δ18OP) local temperature amount on monthly, seasonal, annual timescales. Three main conclusions as following: (1) On monthly time scale, variation δ18OP is mainly...
Abstract. The Eurasian (née European) Modern Pollen Database (EMPD) was established in 2013 to provide a public database of high-quality modern pollen surface samples help support studies past climate, land-cover and land-use using fossil pollen. EMPD is part of, complementary to, the European (EPD) which contains data on found Late Quaternary sedimentary archives throughout region. EPD turn rapidly growing Neotoma database, now primary home for global palaeoecological data. This paper...
The remains of subfossil oribatid mites have been investigated in nine peat layers the eutrophic mire, located southern taiga ecological zone Western Siberia.In total, 17 taxa revealed.Hydrophilic Limnozetes sp. and Hydrozetes sp.dominated all assemblages, which reflects an increased surface wetness mire during entire period its development (8,850 yr).Fluctuations are expressed through changes both species composition relative abundances mites.Decreases accompanied by a decrease proportion...
The article presents results of study the isotope composition and pollen spectra atmospheric precipitation ice taken from marginal parts Korumdu Glacier (North-Chu Ridge, Altai Mountains). was aimed at identification sources ways into nival-glacial region Altai. Investigation tongue summer in its basin has shown that here concentrations are much smaller than similar ones cold Belukha Glacier. last one is located near This difference can be explained by fact main source moisture forming...
Complementary spore-pollen, diatom and geochemical analysis of samples from upper 80 cmof lake sediments Lake Manzherokskoye, situated in the western piedmont region Altai Mountains, revealed correlations between trends local water content changes surrounding dry land vegetation triggered by change overall climate humidity. Ecological complexes studied sediment section reconstruction pH variation based on indicator-species following successions: 1 – a shallow pool during downcore...
