17. Ecological succession of benthic macrofauna following disturbance : Effects of contaminants and in situ sediment remediation
Abstract : More than 70% of the Earth is covered by water, and most of the sea floor consists of soft sediments, such as mud, clay and sand. Thus, soft sediments form one of the most important habitats on Earth, with a high diversity of organisms. READ MORE

18. Benthic use of phytoplankton blooms: uptake, burial and biodiversity effects in a species-poor system
Abstract : Animals living in marine sediments (the second largest habitat on earth) play a major role in global biogeochemical cycling. By feeding on organic matter from settled phytoplankton blooms they produce food for higher trophic levels and nutrients that can fuel primary production. READ MORE

19. Benthic cryptofauna and internal bioeroders on coral reefs
Abstract : The cryptofauna of coral reefs may act as a food source for fish, while being grazers or predators themselves, and hence constitute an important group in the coral reef food web. In addition, the actively eroding taxa of the cryptofauna contribute to the decomposition and recirculation of calcium carbonate and are consequently essential for the rebuilding new coral. READ MORE

20. The effects of crayfish on interactions in freshwater benthic communities
Abstract : This thesis examines how freshwater crayfish affect community interactions in benthic food webs. I have mainly studied the influence of the introduced signal crayfish (Pacifastacus leniusculus) on littoral communities, but also the influence of the native noble crayfish (Astacus astacus).
