| Zusammenfassung |
| Lake Ohrid is likely of Pliocene age and thus commonly referred to as the
oldest existing lake in Europe. In this study spatial variability of recent
sediment composition is assessed using >50 basin wide distributed surface
sediment samples. Analysis of biogeochemical bulk parameters, selected
metals, pigment concentrations as well as grain size distributions revealed
a significant spatial heterogeneity in surface sediment composition. It
implies that sedimentation in Lake Ohrid is controlled by an interaction of
multiple natural and anthropogenic factors and processes. Major factors
controlling surface sediment composition are related to differences in
geological catchment characteristics, anthropogenic land use, and a
counterclockwise rotating surface water current. In some instances processes
controlling sediment composition also seem to impact distribution patterns
of biodiversity, which suggests a common interaction of processes
responsible for both patterns. |
