  1. 6. In situ remediation of contaminated sediments using thin-layer capping efficiency in contaminant retention and ecological implications

    University dissertation from Stockholm : Department of Ecology, Environment and Plant Sciences, Stockholm University

    Author : Göran S. Samuelsson; Stockholms universitet.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Contaminated Sediment Remediation; Activated Carbon; Benthic Community; Ecological Effects; Stress; Resilience; Contaminant Sequestration; Capping Efficiency; Bioavailability; Bioaccumulation; Sediment-to-water fluxes; marin ekotoxikologi; Marine Ecotoxicology;

    Abstract : Hydrophobic organic contaminants (HOCs) often reside in sediments sorbed to particles, most tightly to particles with high content of organic carbon. If persistent, such pollutants can accumulate in the sediment for many years and constitute a contamination risk for sediment-living organisms and organisms at higher trophic levels, including humans.

  2. 7. Coral Reef Habitats and Fish Connectivity Implications for coastal management and fishery

    University dissertation from Stockholm : Department of Ecology, Environment and Plant Sciences, Stockholm University

    Author : Tove Lund Jörgensen; Stockholms universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; anthropogenic disturbance; coral reef habitat; fish community; coastal ecosystems; conservation management; spatial ecology; seascape perspective; holistic approach; Marine Ecotoxicology; marin ekotoxikologi;

    Abstract : Coral reefs have one of the highest levels of biodiversity of all ecosystems in the world and are important for both human livelihood and food security throughout many tropical countries. However, due to increased anthropogenic pressure on marine ecosystems, especially during the last couple of decades, coral reefs have become critically over-fished, and many reefs are now in a degraded state and are facing additional future threats due to further over-exploitation, chemical pollution, sedimentation, and effects of climate change.

  3. 8. Sub-lethal Effects of Anthropogenic Contaminants on Aquatic Invertebrates

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Warren Kunce; Uppsala universitet.; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ecotoxicology; sub-lethal; behavior; biomarkers; thermal tolerance; pesticides; pyrethroids; neonicotinoids; pharmaceuticals; antihistamines; microplastics; mixtures; freshwater; invertebrates; chironomids; damselflies; snails; Biology with specialization in Animal Conservation; Biologi med inriktning mot zoologisk bevarandebiologi;

    Abstract : Anthropogenic contaminants are considered to play a substantial role in the decline of freshwater invertebrate diversity. Sub-lethal effects of many of these contaminants on behaviour and life-history traits of aquatic invertebrates may contribute to their decline. READ MORE

  4. 9. Effects of contrasting types of marine protected areas on seagrass- and coral communities are community-based reserves an important complement to government-managed protected areas?

    University dissertation from Department of Ecology, Environment and Plant Sciences, Stockholm University

    Author : Angelica Chirico; Stockholms universitet.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Marine Ecotoxicology; marin ekotoxikologi;

    Abstract : Coastal ecosystems, including seagrass beds and coral reefs, are among the most ecological and economical important ecosystems on Earth. At the same time as these ecosystems support livelihoods of coastal communities they are being highly degraded worldwide. READ MORE

  5. 10. Uptake and toxicity of brominated flame retardants and pesticides : Studies on littoral organisms and model communities

    University dissertation from Stockholm : Institutionen för systemekologi

    Author : Kerstin Gustafsson; Stockholms universitet.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; aquatic ecotoxicology; ecological interactions; indirect effects; model community studies; toxicity; NATURAL SCIENCES Biology Terrestrial; freshwater and marine ecology; NATURVETENSKAP Biologi Terrestisk; limnisk och marin ekologi;

    Abstract : In this thesis, brackish and freshwater littoral model communities (microcosms) of varying size and complexity were used to study the effects of brominated flame retardants (BFRs) and pesticides. The brackish water microcosms consisted of natural water, sediment and associated organisms, while the larger freshwater microcosms also contained submersed macrophytes (Elodea canadensis). READ MORE
