Long-term forest fire ecology and dynamics in southern Switzerland
TL;DR: Pollen and charcoal analysis at two lakes in southern Switzerland revealed that fire has had a prominent role in changing the woodland composition of this area for more than 7000 years as discussed by the authors, and the sediment of Lago di Origlio for the period between 5100 and 3100 cal was sampled continuously with a time interval of about 10 years.
Journal ArticleDOI
Late‐Glacial radiocarbon‐ and palynostratigraphy on the Swiss Plateau
Brigitta Ammann,André F. Lotter +1 more
TL;DR: A detailed lateglacial radiocarbon stratigraphy for the Swiss Plateau has been established on the basis of over 90 accelerator 14C dates on terrestrial plant macrofossils.
Journal ArticleDOI

Brigitta Ammann,Harry John Betteley Birks,Harry John Betteley Birks,Stephen J. Brooks,U. Eicher,Ulrich von Grafenstein,Wolfgang Hofmann,Geoffrey Lemdahl,Jakob Schwander,Kazimierz Tobolski,Lucia Wick +10 more
TL;DR: In this paper, the presence or absence of lags in biotic responses to rapid climatic changes is assessed by using the δ18O in biogenically precipitated carbonates record global or hemispheric climatic change at the beginning and at the end of the Younger Dryas without any lag at two study sites of Gerzensee and Leysin, Switzerland.
Journal ArticleDOI
Pollen and charcoal in lake sediments compared with historically documented forest fires in southern Switzerland since AD 1920
Willy Tinner,Marco Conedera,Brigitta Ammann,Heinz W. Gäggeler,Sharon Gedye,Richard Jones,Beat Sagesser +6 more
TL;DR: In this article, the results were compared with the number and area of forest fires on different spatial scales in the area around Lago di Origlio as listed in the wildfire database of southern Switzerland since AD 1920.
Journal ArticleDOI
Fire ecology north and south of the Alps since the last ice age
TL;DR: The authors analyzed sediment cores from lakes on the Swiss Plateau (Lobsigensee and Soppensee) for pollen and charcoal to investigate the relationship between vegetation and fire.
