Biotic response to rapid climatic changes during the Late Glacial
Organisms can respond to rapid climatic changes in three ways: 1) adaptation by evolution, affecting physiology and morphology), 2) migration and population dynamics including biogeographical changes) and 3) extinction local or global). Here, the focus is on examples of the second type. Organisms, whether algae, trees, or animals, find their ecological niches in a multi- dimensional space of gradients such as temperature winter, summer, means or …
Late‐glacial climatic oscillations as recorded in Swiss lake sediments
Regional pollen assemblage zones for the late‐glacial period of the Swiss Plateau are introduced and defined. They include four major zones ( Artemisia, Juniperus—Hippophaë, Betula, Pinus PAZ) with several subzones. Pollen and oxygen‐isotope analyses on lacustrine sediments from several lakes in the area reveal four distinct phases of climatic oscillation in the time period of 13 000‐9500 yr BP. The first oscillation, termed the Aegelsee fluctuat…
Die spätglazialen sowie die frühpostglazialen Klimaverhältnisse im Bereiche der Alpen
180/160 isotope analyses on carbonate lake Sediments from Central Europe exhibit abrupt, characteristic variations reflecting temperature changes. Between 13,000 and 11,000 years before present, a more or less continuous warm period (Bölling-Alleröd) existed separated from the Postglacial by the Younger Dryas cold phase. Results from 25 Sites in Central Europe, especially the forelands ot the Alps indicate, with the exception of 3 Sites south of …
Pollen and Oxygen Isotope Analyses on Late- and Post-Glacial Sediments of the Tourbière de Chirens (Dauphiné, France)
The sequence of vegetation phases in the late Glacial was studied in a sediment section from the bog Tourbière de Chirens by means of pollen analysis. 18 O/ 16 O ratios of samples of lacustrine marl, obtained from the same profile, reflect variations of 18 O/ 16 O in precipitation and thus provide an additional, independent paleoclimatic record. The observed 18 O/ 16 O variations agree well with the climatic history as deduced from pollen analysi…
