1. 1. Offshore wind farms - ecological effects of noise and habitat alteration on fish

   Författare :Mathias H. Andersson; Sören Nylin; Magnus Wahlberg; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; renewable energy; fish population; artificial reef; attraction vs. production; habitat structure; reef effect; FAD; bioacoustics; noise disturbance; fish behaviour; detection range; threshold; masking; fish communication and hearing; Marine ecology; Marin ekologi; zoologisk ekologi; Animal Ecology;

   Sammanfattning : There are large gaps in our understanding how fish populations are affected by the anthropogenic noise and the alteration of habitat caused by the construction and operation of offshore wind farms. These issues are of great importance as the construction of offshore wind farms will increase all over the world in the near future. LÄS MER

3. 2. Phosphorus Emissions from Fish Farms : Observed and Predicted Effects

   Författare :Torbjörn Johansson; Kurt Pettersson; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Fish farm; phosphorus; eutrophication; model; Geovetenskap; Earth sciences; Geovetenskap; Sedimentology; sedimentologi;

   Sammanfattning : During the last decades, fish farming has been a rapidly increasing industry in many European and North American countries. Sweden has a large potential for aquaculture, but there is also a strong concern about the effects on the environment that an increased aquaculture production may cause. LÄS MER

5. 4. Effects of habitat structure on tropical fish assemblages

   Författare :Kajsa Garpe; Marcus Öhman; Geoffrey Jones; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Marine ecology; Marin ekologi; marin ekologi; Marine Ecology;

   Sammanfattning : Rates of habitat alteration and degradation are increasing worldwide due to anthropogenic influence. On coral reefs, the loss of live coral reduces structural complexity while facilitating algal increase. In many coastal lagoons seagrass and corals are cleared to make room for cultivated macroalgae.

7. 5. Seaweed in the tropical seascape : Importance, problems and potential

   Författare :Stina Tano; Christina Halling; Sofia Wikström; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Seaweed; Macroalgae; Eucheumoids; Non-indigenous; Haplotype; Fish; Nursery; Epifauna; Diversity; Seaweed farming; Zanzibar; East Africa; Tropical; marin ekotoxikologi; Marine Ecotoxicology;

   Sammanfattning : The increasing demand for seaweed extracts has led to the introduction of non-native seaweeds for farming purposes in many tropical regions. Such intentional introductions can lead to spread of non-native seaweeds from farming areas, which can become established in and alter the dynamics of the recipient ecosystems. LÄS MER
