Sammanfattning : Benthic diatoms are valuable tools for biological monitoring and paleo-ecological reconstruction of past environmental conditions. This thesis aims at describing size-related properties of benthic diatoms and suggests that data assessment for community analysis can be improved by considering the importance of scale. LÄS MER
2. Processes and factors governing benthic community dynamics—environmental change in the Baltic Sea
Sammanfattning : As drivers of biogeochemical cycles and nutrient recycling, such as carbon turnover, the microbial community is essential in sustaining functioning ecosystems. Together with the metazoan community, the microbial community constitute the majority of all life in the benthos. LÄS MER
Sammanfattning : Meiofauna, and especially marine nematodes are common in sediments around the world. Despite very wide ranging distributions in many nematode species, little is presently known about their dispersal mechanisms shaping these patterns. Rafting, and perhaps ballast water transport has been suggested as viable means for nematode long-range transport. LÄS MER
Sammanfattning : Large anthropogenic discharges of oil annually enter the marine environment, in the magnitude from large scale discharges to minor leakage, caused by ship collision accidents or seepage from urban areas. Possible detrimental environmental effects from these discharges differ, from acute lethal to chronic sub-lethal. LÄS MER
