| Abstract | Pollen and macrofossil data from Alpe PAlü, south-eastern Switzerland, are presented. On the basis of these data and the geomorphological evidence for local glacier movement, Holocene climatic oscillations and vegetation change at this upland site (1940 m asl), are reconstructed. The morainic deposits and glacial clays, as well as the pollen data from the base of the pollen profile, clearly show that the Palü glacier, after its retreat from the Cavaglia (Egesen) stade, readvanced once again shortly before the mid-Preboreal. This re-advance was considerably greater than that dating to the Little Ice Age. This early Holocene climatic event is referred to as the Palü Oscillation (Palü-Schwankung) and is considered to be broadly contemporaneous with the previously described Schlaten Oscillation (Schlate n-Schwankung) in the Austrian Alps. The reforestation of the forefield of the moraine was interrupted at least twice during this oscillation, and, compared with neighbouring sites at the same altitude, it appears to be at least 500–700 years younger, i. e. it post-dates 9400 B.P. Though the Palü Oscillation is a Holocene phenomenon, the associated vegetation changes are Late-glacial in character, e.g.Arlemisia and Chenopodiaceae increase andHippophaë is recorded.Alnus viridis replacesBelula andSalix, which were important in the earlier part of the Holocene, at about 5000 B.P. There is no clear evidence that forest burning is attributable to human activity. The use ofLarix-dominated areas as pasture (Lärchwiesen) begins in the mid-Bronze Age. A strong decline inPicea (spruce) andLarix (larch), and an increase in Poaceae,Plantago and other herbs in the uppermost horizons reflect more intensive pastoral farming that began in the high Middle Ages. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
