AbstractThe pre-last glacial maximum paleolake sediments at Baumkirchen, western Austria, are well known in Alpine Quaternary stratigraphy as being the type locality of the Middle to Upper Würmian transition. Their location provides a rare opportunity to investigate the vegetation history of the interior of the Alps during the last glacial cycle. A recent renewed research effort involving new drilling revealed a 250-m-thick lacustrine sequence with an older, ca. Marine Oxygen Isotope Stage (MIS) 4 phase and a younger, mid- to late MIS 3 phase. Pollen analysis reveals generally poor preservation and very low pollen concentration due to very high sedimentation rates. On the basis of pollen percentages and influx rates, six pollen zones (PZ) were assigned. PZ1 and 2 correspond to the entire ca. MIS 4 section and are characterized by only scattered vegetation representing an extremely cold and dry climate. Two stadials and two interstadials were identified in the MIS 3 section. The interstadials are characterized by well-developed open vegetation with some stands of trees, with the upper PZ6 being better developed but still forest-free. On the basis of previous radiocarbon dating, this zone (PZ6) is correlated to Greenland Interstadial (GI) 7 and the lower interstadial (PZ4) tentatively to GI 8.

<p>Climate and vegetation history of Upper Dnieper region (Western Russia) is investigated poorly while archaeological studies provide evidences of human activities during last 3 millennia. Our study presents vegetation reconstruction based on pollen analysis of sediments extracted from two sites in Smolensk region. The first site is located in Katynka river bassin and pollen analysis of extracted buried soil, alluvium and peat sediments demonstrates vegetation dynamics in archaeologically rich area over 5 millennia. The second site is located in 50 km from to the west from Smolensk and in 15 km to east from the Russian-Belarus state border. The analysis of extracted peat sediments presents regional history of vegetation. The aim of our study is to compare data obtained from both sites and to estimate climate and human influence on vegetation during last two millennia when activities associated with agriculture changed Dnieper valley landscape significantly.</p><p>The first results of pollen analysis data of the first site allow to register significant human impact on vegetation 2.0-0.8 ka BP. Before that period pollen of indigenous forest trees dominates in spectra while since 2.0 ka BP pollen compassion changes dramatically and pollen of <em>Betula</em> and <em>Pinus</em> is in majority in so-called “Gnezdovo soil” lay. Medieval lays of sapropel contains mostly pollen of <em>Pinus</em> with admixture of <em>Betula</em> and <em>Alnus</em>. Taxonomic diversity and presence of meadow herbs, weeds and cultivated taxa pollen increases significantly (up to 30%). Dynamics of pollen composition in specimens from the second site allows us to register slow processes of indigenous vegetation recovery over last 3 centuries approximately. Modern analogue technique applied on pollen data and analysis of historical data makes possible to separate impacts of climate and human on vegetation of the past and to reconstruct the climate of last two millennia.</p><p>The study was funded by RFBR, project number 19-34-90172.</p><p><br><br></p>

Pollen analysis of 4 m of peat, swamp-soil and lake sediments dated from 0 to > 43800 years b.p. indicates the occurrence of three major pollen assemblage zones. During Zone 1 (11000-0 years b.p.) the area had temperate rainforest and the climate was warm, moist and interglacial. During Zone 2 ( ?25000-l 1000 years b.p.), correlated approximately with the last period of glaciation, the vegetation was mainly grassland and the climate was considerably colder than present. In late glacial times (14000-11000 years b.p.) pollen of shrub and tree taxa increased, especially during the later part of the period as the climate became warmer and moister. During Zone 3 (more than 4 3 0 0 0 -?25000 years b.p.) the vegetation was predominantly sub-alpine and alpine. This vegetation represents an interstadial assemblage for a lowland site. The climate was cool and moist. The results are compared with sites of similar age in Tasmania, and with sites from temperate forest environments in Chile and New Zealand.
