  2. 1. Grazing in Macroalgae Communities of the Baltic Sea

    Author : Roland Engkvist; Hans Kautsky; Högskolan i Kalmar; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Akvatisk ekologi; Aquatic Ecology;

    Abstract : Fucus vesiculosus and Fucus serratus are the only large, structuring perennial brown macroalgae in the low salinity waters of the Swedish coast of the Baltic Proper. Since the 1970s there are reports of declining Fucus vesiculosus stands from several locations around the Baltic Proper, but also indications of recoveries e.g. READ MORE

  4. 2. Trophic effects on the maintenance of biodiversity in the Fucus zone

    Author : Sonja Råberg; Lena Kautsky; Christer Brönmark; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biodiversity; epiphytes; eutrophication; faunal assemblage; filamentous algae; Fucus radicans; Fucus vesiculosus; grazers; nutrient supply; Marine ecology; Marin ekologi; Plant Ecology; växtekologi;

    Abstract : Ecologically important macroalgae with large thalli and complex structures are threatened worldwide due to anthropogenic activities such as pollution. In the northern Baltic Sea the salinity is very low; the only large algae producing complex structural habitats found there are the fucoid species Fucus radicans and F. vesiculosus. READ MORE

  5. 3. Sustainability Aspects of Bioenergy and Nutrient Recovery from Marine Biomass : Baltic Sea case studies

    Author : Emma Risén; Maria Malmström; Fredrik Gröndahl; Stanley Michele; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Industrial Ecology; Industriell ekologi;

    Abstract : Coastal areas around the world are experiencing environmental problems such as climate change and eutrophication. These, in turn, lead to emerging challenges with excessive amounts of biomass that impact coastal communities. READ MORE

  6. 4. Trends and exposure of naturally produced brominated substances in Baltic biota - with focus on OH-PBDEs, MeO-PBDEs and PBDDs

    Author : Karin Löfstrand; Lillemor Asplund; Åke Bergman; Adrian Covaci; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Batlic Sea; Natural production; OH-PBDE; MeO-PBDE; PBDD; Environmental chemistry; Miljökemi; miljökemi; Environmental Chemistry;

    Abstract : The semi-enclosed and brackish Baltic Sea has become heavily polluted by nutrients, anthropogenic organic and inorganic chemicals via human activities. Persistent organic pollutants (POPs) have been thoroughly investigated due to their linkage to toxic effects observed in Baltic biota. There has been far less focus on semi-persistent pollutants e.

  7. 5. Exposure and effects of naturally produced hydroxylated polybrominated diphenyl ethers in fish : Implications for Baltic Sea wildlife

    Author : Johan Gustafsson; Lillemor Asplund; Pim E.G. Leonards; Marja H. Lamoree; Robert Letcher; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ecotoxicology; Metabolomics; OH-PBDE; Algae; Cyanobacteria; Natural products; Thiamine; Health; Biomarker; Seasonal variation; Perch; Zebrafish; Flame retardant; Mixture; 6-OH-BDE47; Energy metabolism; Endocrine disruption; Neurotoxicity; OXPHOS; Environmental Chemistry; miljökemi;

    Abstract : The aim of this thesis was to investigate if naturally produced hydroxylated polybrominated diphenyl ethers (OH-PBDEs) are causing negative health effects for Baltic Sea wildlife. In the laboratory, OH-PBDEs have shown to be potent disrupters of energy metabolism as well as endocrine disruptors and neurotoxins. READ MORE
