Abstract
- The Tibetan Plateau, also known as the “Water Tower of Asia” because of its function as a water storage and supply region, responds dramatically to modern climate changes. Paleoecological shifts inferred from lake sediment archives provide essential insights into past climate changes, and the processes that drove those shifts. This is especially true for studies of lakes in endorheic basins on the Tibetan Plateau, where lake level is regulated predominantly by Monsoon intensity. Such water bodies provide excellent opportunities to reconstruct past changes in humidity. Most paleolimnological investigations of lakes on the Tibetan Plateau, however, have involved the study of a single sediment core, making it difficult to discern between changes caused by local events and those caused by lake-wide or regional processes. Here we present results from a paleolimnological study of Lake Taro Co, a currently closed-basin lake in Central Tibet. We compared a sediment record from the central part of the lake to a record from the near-shore area, and present results of sedimentological and bioindicator (chironomid, diatom, pollen) analyses from both records. Results show three periods of lake-wide ecosystem change (> ca. 5250, 5250–2250 and<br />Bundesministerium für Bildung und Forschung http://dx.doi.org/10.13039/501100002347<br />Fellowships for Young International Scientists http://dx.doi.org/10.13039/501100010895<br />NSFC Research Fund for International Young Scientists (CN)<br />Deutsche Forschungsgemeinschaft (DFG) (DE)<br />National Natural Science Foundation of China http://dx.doi.org/10.13039/501100001809<br />Technische Universität Braunschweig (1042)
