Research project

The end of the Pleistocene tundra steppe – interactions between vegetation, climate and large herbivores in Beringia during the late Quaternary

 Frieze Project Tundra steppe

As part of the project group ‘The impact of coastline shifts, climate and herbivory on Arctic vegetation during the Quaternary’, the research project reveals the ecological interactions of climate, vegetation and large herbivores in the Arctic during the late Quaternary by combining palaeobotanical results with studies of modern plant communities in Yakutia, Russian Federation.  Macroscopic plant remains are preserved in excellent condition in syngenetic permafrost sequences in the Yana and Kolyma catchment areas and are used to reconstruct structure, composition and dynamics of the late Quaternary vegetation in NE-Siberia. The reconstructed palaeovegetation will be compared then with modern plant cover in North Yakutia: on the one hand with unaffected vegetation along the main, climatically controlled gradient and on the other hand with vegetation heavily disturbed by grazing. By combining both approaches, the relative proportions of climate and grazing effects as potential main drivers determining the characteristics of extant and Pleistocene vegetation in western Beringia will be identified.

The project includes expeditions to Yakutia in 2014 and 2015. The first expedition is already completed. An outcrop close to Batagai was explored and samples were taken for plant remains and sediment composition analysis. At the same time, the recent steppe vegetation in the surrounding Yana highlands was studied by the working group of Karsten Wesche (Senckenberg Görlitz) in the scope of a sister project.

With a picture taken on the expedition 2014, K. Ashastina 2017 became the winner of the Nature photo contest „Scientist at Work“.
