  2. 11. Environmental Effects from Wave Power : Artificial Reefs and Incidental No-take Zones

    Author : Anke Bender; Jan Sundberg; Olivia Langhamer; Louise Kregting; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Marine renewable energy; Wave power; Environmental monitoring; Artificial reef; No-take zone; Decapods; Nephrops norvegicus; ROV; Cage fishing; Biologi; Biology;

    Abstract : Marine renewable technologies have rapidly been developing over the past decade. Wave power is one of the renewable sources and has the potential securing the renewable electricity production. READ MORE

  4. 12. Benthic cryptofauna and internal bioeroders on coral reefs

    Author : Helena Strömberg; Charlotta Kvarnemo; Pat Hutchings; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; bioerosion; cryptofauna; coral; invertebrates; damselfish; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

    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.

  5. 13. Habitat structure, degradation and management effects on coral reef fish communities

    Author : Saleh A.S. Yahya; Martin Gullström; Sören Nylin; Narriman Jiddawi; Yunus Mgaya; Gunilla Rosenqvist; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; fish assemblages; climate change; coral degradation; Indian Ocean; patch reefs; coral bleaching; resilience; zoologisk ekologi; Animal Ecology;

    Abstract : Coral reefs are among the most diverse and productive ecosystems on earth, and are critical to the survival of tropical marine ecosystems and sustenance of local human populations. However, coral reefs are quite vulnerable to disturbances, both natural and anthropogenic. READ MORE

  6. 14. Macroalgae in tropical seascapes : regulating factors and functions in the coastal ecosystem

    Author : Gustaf Lilliesköld Sjöö; Max Troell; Nils Kautsky; Lena Kautsky; Alina Szmant; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Macroalgae; Coral reefs; Nutrients; Herbivory; Ecological functions; East Africa; Regulating factors; Anthropogenic influence; Seaweed farming; Bioindicator; marin ekotoxikologi; Marine Ecotoxicology;

    Abstract : Although macroalgae usually are inconspicuous on pristine coral reefs, they often thrive on reefs that are subjected to various types of anthropogenic disturbance. This thesis consists of five papers and investigates how biomass and composition of macroalgal communities on coral reefs are affected by regulating factors, such as nutrient availability, herbivory, substrate availability and hydrodynamic forces.

  7. 15. Sea cages, seaweeds and seascapes : Causes and consequences of spatial links between aquaculture and ecosystems

    Author : Nils Hedberg; Tedengren Michael; Nils Kautsky; Barry Costa-Pierce; Stockholms universitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Spatial links; Aquaculture; Coral Reefs; Seagrass; Seascape; marin ekotoxikologi; Marine Ecotoxicology;

    Abstract : Aquaculture is of growing importance in the global seafood production. The environmental impact of aquaculture will largely depend on the type of environment in which the aquaculture system is placed. READ MORE
