Testing the performance of sodium polytungstate and lithium heteropolytungstate as non-toxic dense media for pollen extraction from lake and peat sediment samples

Leipe C, Kobe F, Müller S

Pollen analysis is one of the most important methods to reconstruct past climate change and to understand prehistoric and early historic human-environment interactions. Every study based on fossil pollen assemblages from sedimentary archives starts with the preparation of collected sample material. The most widely employed protocols to concentrate pollen involve the use of several chemicals including hydrofluoric acid (HF), which is extremely hazardous to human health. As an alternative to HF, we have tested the reliability of dense [...]

Christian Leipe BAP archaeobotanical analysis featured in Yomiuri Shimbun newspaper article!

Thank you to Dr. Pavel Tarasov for sharing the following BHAP/BAP news!: The Yomiuri Shimbun, a Japanese national newspaper with a 140-year history and a daily readership of more than 9 million copies every morning, recently published an article about ancient barley seeds excavated from the Hamanaka 2 site on Rebun Island. The story, written by a Japanese journalist, is based on the samples obtained through the BHAP international summer school excavations and on the archaeobotanical analysis performed by [...]

Insight into the Last Glacial Maximum climate and environments of the Baikal region

Tarasov PE, Ilyashuk BP, Leipe C, Müller S, Plessen B, Hoelzmann P, Kostrova SS, Bezrukova E, Meyer H

This study presents a multi-proxy record from Lake Kotokel in the Baikal region at decadal-to-multidecadal resolution and provides a reconstruction of terrestrial and aquatic environments in the area during a 2000-year interval of globally harsh climate often referred to as the Last Glacial Maximum (LGM). The studied lake is situated near the eastern shoreline of Lake Baikal, in a climatically sensitive zone that hosts boreal taiga and cold deciduous forests, cold steppe associations typical for northern Mongolia, and [...]

Dr. Pavel Tarasov and Dr. Christian Leipe research update from Siberia!

Exciting research update from Dr. Christian Leipe: Pavel and I are back from Siberia. It was a successful and interesting trip even with lots of snow and ice, which I haven’t seen for a long time. We would like to share some photos and information for the next newsletter. Here are the captions for the photos attached. Pavel Tarasov giving a public lecture within the framework of the BAP at the Institute of Geochemistry of the Russian Academy of Sciences [...]

Late glacial and early Holocene environments and human occupation in Brandenburg, eastern Germany

Kobe F, Bittner MK, Leipe C, Hoelzmann P, Long T, Wagner M, Zibulski R, Tarasov PE

The paper reports on the results of the pollen, plant macrofossil and geochemical analyses and the AMS 14C-based chronology of the «Rüdersdorf» outcrop situated east of Berlin in Brandenburg (Germany). The postglacial landscape changed from an open one to generally forested by ca. 14 cal. kyr BP. Woody plants (mainly birch and pine) contributed up to 85% to the pollen assemblages ca. 13.4–12.5 cal. kyr BP. The subsequent Younger Dryas (YD) interval is characterized by a decrease in [...]
