Conifer stomata analysis in Late Quaternary paleoecolgy in Scandinavia

Updated 2003-04-24

The project aims to develop the use of stomata analysis as a Quaternary palaeoecological tool in Scandinavia following the lead in North America and Siberia (Hansen 1995, Gervais and MacDonald, 2001). A key is being produced to identify the main Scandinavian conifers from their stomata. Surface samples of lake sediment will be collected in catchments with and without the main conifers to determine the extent to which stomata are transported beyond the catchment in which the trees occur. Paleoecological work will be carried out to obtain supplementary information about the timing of the appearance and disappearance of Larix sibirica (Kullman, 1998) and to apply the knowledge gained on the dispersibility of stomata to the arrival and increase of other conifers.Surface lake samples have been collected from lakes in southern and central Sweden. I would like to find some small lakes to surface sample in Northern Sweden. Three promising areas with a high density of lakes have been identified around the Abisko field station and Kiruna areas. I will use a standard surface sediment sampler and will sample between 6 and 12 lakes. This work will have wide applicability in NW Europe, replacing the use of Trautmann's key (1953), and will contribute significantly to the increasing use of stomata as a palaeoecological tool.
