“…For example, during the last glacial-interglacial cycle, besides the temperature-driven south-north shift, the forest biomes extended north-westward after the last deglaciation (particularly during the Holocene) and shrank southeastward in the late Holocene (precipitation-driven) at the margins of the Asian Summer Monsoon (Ni et al 2014;Cao et al 2015;Tian et al 2016). In northern Siberia, the forest biomes shifted into the present tundra region during the early and middle Holocene, as revealed by macrofossil- (Binney et al 2009) and pollen-based vegetation reconstructions (Tarasov et al 1998(Tarasov et al , 2000Bigelow et al 2003;Rudaya et al 2016;Binney et al 2017;Zhilich et al 2017). However, these previous studies have either a restricted spatial extent (e.g.…”

Recent global warming is pronounced in high-latitude regions (e.g. northern Asia), and will cause the vegetation to change. Future vegetation trends (e.g. the "arctic greening") will feed back into atmospheric circulation and the global climate system. Understanding the nature and causes of past vegetation changes is important for predicting the composition and distribution of future vegetation communities. Fossil pollen records from 468 sites in northern and eastern Asia were biomised at selected times between 40 cal ka bp and today. Biomes were also simulated using a climate-driven biome model and results from the two approaches compared in order to help understand the mechanisms behind the observed vegetation changes. The consistent biome results inferred by both approaches reveal that long-term and broad-scale vegetation patterns reflect globalto hemispheric-scale climate changes. Forest biomes increase around the beginning of the late deglaciation, become more widespread during the early and middle Holocene, and decrease in the late Holocene in fringe areas of the Asian Summer Monsoon. At the southern and southwestern margins of the taiga, forest increases in the early Holocene and shows notable species succession, which may have been caused by winter warming at ca. 7 cal ka bp. At the northeastern taiga margin (central Yakutia and northeastern Siberia), shrub expansion during the last deglaciation appears to prevent the permafrost from thawing and hinders the northward expansion of evergreen needle-leaved species until ca. 7 cal ka bp. The vegetationclimate disequilibrium during the early Holocene in the taiga-tundra transition zone suggests that projected climate warming will not cause a northward expansion of evergreen needle-leaved species.

“…Following the Holocene climatic optimum (6500-5900 year BP). The Gorno Altai as well as the adjoining Mongolian Altai climates experienced increased continentality and aridity (Rudaya and Li 2013;Rudaya et al 2016), which promoted the establishment of the current ecological zoning with forest-steppe in the foothills, and semidesert on the mountain plateaus and continental depressions. The fine sedimentary (sand/loess) deposits over most of the Central and Southern Altai basins are rather thin because of the intensive aeolian deflation that continues until the present time.…”

“…A common trait of all these communities is the practice and preservation of a traditional pastoral economy. Marked shifts in the distribution of vegetation zones, associated with the sub-Boreal climatic deterioration (Litt et al 2001), are evident across southern Siberia in the mid-and late Holocene records from the southern Urals to the Russian Far East (Ryabogina 2001;Zakh et al 2010;Rudaya et al 2012Rudaya et al , 2016Zhilich et al 2017;Chlachula and Krupyanko 2016). In SW Siberia, this development is documented by a general prevalence of open steppe vegetation elements under a relatively warm and dry climate with isolated birch forests between 4400 and 3750 year BP (Rudaya et al 2012).…”

These climate change patterns were accentuated by negative atmospheric humidity during the period ca.…”

The Altai Mountains are well-known for their unique archaeological records, with rich, chronologically sequenced Palaeolithic, Neolithic and the Bronze Age (late fourth-early first millennium BC) sites and, in particular, the Iron Age Scytho-Siberian and early historical monuments represented by burial sites, ritual structures, and rock-art. The Altai prehistoric archaeological localities are distributed across a broad range of topographic and ecological settings, encompassing altitudinal zones from 800 m asl in the lower reaches of glacial river valleys up to 2500/3000 m asl on the high mountain plateaus. The partial spatial overlap of these (often multi-component) geoarchaeological loci over time suggests that similar adaptive strategies were employed by countless generations of hunter and later nomadic communities-their actions constrained by the locally specific forms of (palaeo-)relief and the associated ecosystems. The dynamics of the initial occupation of the boreal and alpine Altai landscapes and subsequent processes of (re-)colonisation during the Final Pleistocene-Holocene transition are directly linked to transformations in the regional hydrological systems after the LGM. The principal settings for early pastoral settlements were the xerothermic grasslands that formed on the flat glacio-lacustrine terraces which rise above the modern fluvial floodplains-the remains of ice-dammed wastage lake basins drained at the end of the Pleistocene (15,000-13,000 year BP). Marked climatic changes, evidenced by regional variations in temperature and humidity across the territory, are well attested in the geological, biotic and archaeological records. The initial Sub-Boreal aridification correlated with the beginnings of the Altai Bronze Age traditions continued until the early Iron Age-causing an expansion of parkland-steppe in the main valleys and a forest retreat in the foothills. Mountain steppes constituted the most essential food-procurement habitat for the Holocene prehistoric and historical settlements of Southern Altai. The current degradation of insular alpine permafrost poses an imminent threat to preservation of the region's most precious archaeological monuments-the frozen burial mounds of the Pazyryk culture (sixth-third century BC) belonging to the UNESCO World cultural heritage.

“…The development of polar ecosystems under the continuously changing climate conditions is an important problem of paleoclimatic and paleoecological investigations Fritz et al, 2016). Despite the environmental development that has been reconstructed in almost the entire northern hemisphere (Mayewski et al, 2004;Schirrmeister et al, 2011;Meyer et al, 2015;Rudaya et al, 2016), paleoecological and paleoclimatic data on the Siberian sector of the Arctic region are still insufficient (Nazarova, 2012;Palagushkina et al, 2012;Nazarova et al, 2013a, b;Frolova et al, 2013Frolova et al, , 2014Solovieva et al, 2005Solovieva et al, , 2008.…”

⎯A sediment core from Khatanga-12 Lake (Taimyr Peninsula, Krasnoyarsk krai) has been studied. The 131.5-cm-long core covers ca. 7100 years of sedimentation. Chironomid analysis, a qualitative reconstruction of the paleoenvironment in the region, and a quantitative reconstruction of variations of the mean July air temperature and in the water depth of the lake have been performed using Northern Russia chironomid-inferred mean July temperature models (Nazarova et al., , 2011. Khatanga-12 Lake was formed during the Middle Holocene warming as a result of thermokarst processes. The development of the lake ecosystem at different stages of its development was influenced by climatic and cryolithogenic factors. The Middle Holocene warming, which occurred around 7100-6250 cal. years BP, activated thermokarst processes and resulted in the formation of the lake basin. Later, between 6250 and 4500 cal. years BP, a period of cooling took place, as is proved by chironomid analysis. The bottom sediments of the lake during this period were formed by erosion processes on the lake shores. The reconstructed conditions were close to the modern after 2500 cal. years BP.
