1. Swedish seagrass ecosystems in a changing climate : Coastal connectivity and global change sensitivity
Abstract : Coastal shallow-water ecosystems are essential for providing several goods and services globally, with seagrasses as an important contributor for maintaining high biodiversity and productivity within the nearshore seascape. The temperate species Zostera marina serves as a vital habitat for many species, including ecologically and economically important juvenile fish. READ MORE

2. Patterns of small-scale coastal fisheries and local fisheries management in Tanzania : adaptation to a changing climate
Abstract : Coastal habitats like mangroves, seagrass meadows, coral reefs, and adjacent offshore waters constitute an important part of the tropical coastal seascape. They provide conducive environmental conditions for fish and other marine animals, which serve as food and income for coastal communities around the world. READ MORE

3. Sediment resuspension : Impacts and extent of human disturbances
Abstract : Resuspension of sediment by anthropogenic disturbances is a concern due to the impacts it has on organisms and ecosystems. Bottom trawling is one major cause of sediment resuspension. A field study showed that a small trawl created a sediment plume 120 - 150 m wide and 15-18 m high (Paper 1). The sediment in the same study was highly contaminated. READ MORE

4. Paleoenvironmental and paleoclimatic changes in northeast Thailand during the Holocene
Abstract : The long-term climatic and environmental history of Southeast Asia is still fragmentary. This thesis therefore aims at studying lake sediment/peat sequences using a multi-proxy approach to reconstruct the environmental history and the impact of past changes in monsoon variability and intensity on lake ecosystems in Thailand.

5. Early Life History of the cold-water coral Lophelia pertusa - with implications for dispersal
Abstract : For sessile marine invertebrates the pelagic larval stage is the only means for dispersal, and thus govern population connectivity and maintenance of genetic diversity. It is also a kind of life insurance, i.e. it reduces the risk of extinctions. READ MORE
