Well-hidden forests? Modern pollen spectra from Central Yakutia (Eastern Siberia) contribute to the interpretation of the last glacial vegetation in Central Europe

Popis výsledku v původním jazyce

The landscape of central Europe is thought to have been dominated by steppe, forest-steppe, or tundra during the Last Glacial. This classical view is mostly based on the pollen records. However, as the pollen production and taphonomy during the cold periods are largely unknown, modern analogies of past landscapes need to be involved to provide more plausible vegetation reconstructions. Here we performed pollen analyses of recent samples from small lakes in Yakutia, eastern Siberia, a cold region where larch taiga forest is maintained by water from cyclically melting permafrost. We compared the pollen samples using multivariate (PCA) and analogue matching techniques with 830 fossil pollen samples from central Europe dated to MIS3-MIS1 (ca 35,000-11,700 cal BP). We have shown that the non-arboreal pollen proportion is around 50% in the lakes within Yakutian forested landscape, while such proportions have been interpreted as an indication of forestless landscape in European fossil records. Some central European fossil samples are more similar to samples from present-day Yakutia than to the South Siberian steppes so far considered analogous; this is especially true for samples from areas on unconsolidated bedrock with water-saturated permafrost from the Late Glacial, Bolling-Allerod interstadials. We advocate the idea of extending existing interpretations of past landscapes. The fossil pollen might not only reflect steppe-tundra vegetation, but, in addition to that, at least the Late Glacial pollen samples from central Europe may reflect a landscape forested by &apos;invisible&apos; larch with spatially limited steppe patches, like the one found in present-day Yakutia.
