1. 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
2. Investigations of species richness effects on ecosystem functioning using stream-living macroinvertebrates as model organisms
Sammanfattning : The work in this thesis deals with effects of changed species richness on process rates among stream-living macroinvertebrates. Global biodiversity is decreasing rapidly and it is poorly known what the consequences of this loss may be for ecosystems and the services they provide. LÄS MER
3. Sediment remediation using activated carbon: amending knowledge gaps
Sammanfattning : Many coastal sediments have accumulated large quantities of contaminants from past anthropogenic activities and now act as a secondary emission source of legacy pollutants to coastal ecosystems. New sediment remediation strategies are needed to address widespread sediment pollution. LÄS MER
4. Biodiversity and ecosystem functioning in created agricultural wetlands
Sammanfattning : This doctoral dissertation was produced in a cooperation between Halmstad University (Wetland Research Centre, School of Business and Engineering) and Lund University (Limnology & Marine Biology, Department of Ecology).Abstract . LÄS MER
5. Habitat compensation in nature-like fishways : Effects on benthos and fish
Sammanfattning : The construction of nature-like fishways has become an increasingly common measure to restore longitudinal connectivity in streams and rivers affected by hydroelectric development. These fishways also have the potential to function as habitat compensation measures when running waters have been degraded or lost. LÄS MER
