  1. 1. Seagrasses and Eutrophication Interactions between seagrass photosynthesis, epiphytes, macroalgae and mussels

    Author : Esther Francis Mvungi; Mats Björk; Thomas J. Lyimo; Jens Borum; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; CO2; epiphytes; eutrophication; mussels; pH; Photosynthetic activities; seagrasses; Ulva; NATURAL SCIENCES Biology Organism biology Plant physiology; NATURVETENSKAP Biologi Organismbiologi Växtfysiologi; växtfysiologi; Plant Physiology;

    Abstract : Seagrass meadows are highly productive, ecologically and economically valuable ecosystems. However, increased human activities along the coastal areas leading to processes such as eutrophication have resulted in the rapid loss and deterioration of seagrass ecosystems worldwide. READ MORE

  2. 2. Benthic metabolism and sediment nitrogen cycling in Baltic sea coastal areas the role of eutrophication, hypoxia and bioturbation

    University dissertation from Department of Geological Sciences, Stockholm Univeristy

    Author : Stefano Bonaglia; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Eutrophication; Sediment; Benthic Flux; Nitrogen Cycle; Denitrification; Baltic Sea; Biogeochemistry; biogeokemi; marin- och brackvattensekologi; Marine and Brackish Water Ecology; marin ekologi; Marine Ecology; geokemi; Geochemistry;

    Abstract : Eutrophication is one of the greatest threats for the Baltic Sea, and one of its more critical consequences is bottom water hypoxia. Nutrient enrichment and oxygen-depletion affect both the deep central basins and a number of coastal areas, even though strategies for nutrient reduction have lately been implemented. READ MORE

  3. 3. Predictive Models and Eutrophication Effects of Fish Farms

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Lennart Nordvarg; [2001]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Fish farm; eutrophication; model; Geovetenskap; NATURAL SCIENCES Earth sciences; NATURVETENSKAP Geovetenskap; Sedimentology; sedimentologi;

    Abstract : Aquaculture has become one of the fastest growing food industries in the world. Like many other industries, aquaculture, and especially fish farms may cause negative effects on the environment, such as eutrophication, which is recognised as a major threat to aquatic ecosystems.

  4. 4. Transboundary Law for Social-Ecological Resilience? A Study on Eutrophication in the Baltic Sea Area

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Brita Bohman; Jonas Ebbesson; Lena Gipperth; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; transboundary pollution control; transboundary law; eutrophication; social-ecological resilience; ecosystem approach; environmental law; environmental governance; the Baltic Sea; ocean governance; miljörätt; Environmental Law;

    Abstract : This dissertation evaluates the role and effectiveness of law in the transboundary environmental governance of the Baltic Sea with regard to eutrophication. To this end, it reviews the applicable international agreements with their related instruments, as well as the EU legal frameworks, for the protection of the Baltic Sea environment on the basis of theories on resilience in social-ecological systems.

  5. 5. Long-term changes in macroalgal vegetation on the Swedish coast An evaluation of eutrophication effects with special emphasis on increased organic sedimentation

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Britas Klemens Eriksson; Francisco Xavier Niell Castanera; [2002]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ecology; Baltic Sea; Eutrophication; Fragmentation; Fucus vesiculosus; Functional group; Gullmar Fjord; Macroalgae; Long-term changes; Reproduction; Sedimentation; Ekologi; NATURAL SCIENCES Biology Terrestrial; freshwater and marine ecology; NATURVETENSKAP Biologi Terrestisk; limnisk och marin ekologi; ekologisk botanik; Ecological Botany;

    Abstract : In this thesis I examine and evaluate the effects of a documented large-scale eutrophication on macroalgal vegetation on the Swedish coast. During the past century the load of nutrients has increased manifold in the Baltic Sea area, increasing primary production and organic sedimentation significantly. READ MORE
