2. Waterfowl in temperate eutrophic lakes - Interactions with macroinvertebrates, submerged vegetation and fish
Sammanfattning : The aim of this thesis was to explore some of the important links between waterfowl and the biota in shallow eutrophic lakes in temperate areas. Waterfowl depend on macroinvertebrates as sources of protein and calcium, which are essential for egg production and growth. Macroinvertebrates in turn depend on submerged vegetation for food and shelter. LÄS MER
3. Late Holocene humidity variability in central Sweden
Sammanfattning : The aim of this thesis was to reconstruct humidity variability in central Sweden during the late Holocene. A multi-proxy approach was used to infer humidity changes as recorded in a lake and a mire. Age-models were constructed based on radiocarbon dating and the Askja-1875 tephra. LÄS MER

5. Spring dynamics in shallow lakes: the role of plankton, fish and macrophytes in a changing climate
Sammanfattning : Shallow lakes such as Lake Krankesjön are characterized by their extended littoral zones, usually covered by submersed and emergent vegetation. In paper 1, I investigated the relationship between turbidity and macrophyte growth (Chara spp. LÄS MER
