Abstract

Within the frame of the EU project "BAFE" (Biodiversity in Alpine Ecosystems) and the EU network "EVOLTREE" (Evolution of Trees as Drivers of Terrestrial Biodiversity) translocation experiments were established, which cover an altitudinal range of nearly 1,000 m (up to 1,780 m above sea level). After 10 years of exposure, basic material and surviving juvenile plants were compared genetically with each other. The present study addresses provenance samples of each of European larch (Larix europaea), stone pine (Pinus mugo) and Norway spruce (Picea abies). Comparing the surviving populations at three elevations, separated each by at least 400 m vertically, certain variation parameters reflect trends with regard to altitudes, which are running in opposite direction in the case of European larch and stone pine, while pronounced tendencies are not obvious in Norway spruce. Independently of such trends, the studied species reveal remarkable differences with respect to genetic multiplicity and diversity: lowest values are indicated for European larch while maximum values are evident in the case of the stone pine. Each of the three species shows differences between viabilities of genotypes at single enzyme coding gene loci. Environmental changes, which coincide with the translocation experiments and its inferences on the genetic structures of populations, offer new possibilities for an analysis of impacts of climate change on biodiversity parameters.
