  2. 1. The importance of biodiversity for ecosystem processes in sediments : experimental examples from the Baltic Sea

    Author : Johan Näslund; Jonas Gunnarsson; Sara Sjöling; Nils Kautsky; Antoine Grémare; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biodiversity; Soft-bottom sediment; Ecosystem processes; Ecosystem function; Benthic-pelagic coupling; Baltic Sea; Trophic interactions; Pollutant biodegradation; Organic matter mineralization; Deposit feeder; Detritivore; Invasive species; Marine ecology; Marin ekologi; marin ekotoxikologi; Marine Ecotoxicology;

    Abstract : Aquatic sediments are, by surface, the largest habitat on Earth. A wide diversity of organisms inhabit these sediments and by their actions they have a large influence on and also mediate many ecosystem processes. READ MORE

  4. 2. Unravelling Sustainability : The complex dynamics of emergent environmental governance and management systems at multiple scales

    Author : Lucas Dawson; Ingrid Stjernquist; Marine Elbakidze; Raimonds Ernsteins; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Integrated adaptive environmental governance and management; Social-ecological system dynamics; Complex systems; Sustainability transitions; Sustainability strategies; Multi-level governance; Causal loop diagrams; Green Infrastructure; Landscape restoration; Habitat restoration; Biodiversity conservation; Comprehensive planning; Stakeholder participation; System thinking; Water Framework Directive; Sustainable water governance; Collaborative learning; Communities of practice; Knowledge management; Physical Geography; naturgeografi;

    Abstract : This thesis adopts a complex systems approach to investigate the dynamic emergence of sustainable environmental governance and management systems in multiple contexts in Europe. Accelerating rates of environmental degradation across the world have called the legitimacy of previous environmental governance and management arrangements into question. READ MORE

  5. 3. Biodiversity and genetic patterns in marine invertebrates

    Author : Emma Vodoti; Göteborgs universitet; []
    Keywords : zoology; marine biodiversity;

    Abstract : Abstract: Systematics based on genetic data has both confirmed and contradicted earlier, morphologically defined species and their relatedness. Morphology does not always correspond to genetic lineages, and this will inevitably affect both traditional systematics as well as biodiversity assessments. READ MORE

  6. 4. Benthic use of phytoplankton blooms: uptake, burial and biodiversity effects in a species-poor system

    Author : Agnes M. L. Karlson; Ragnar Elmgren; Carlo Heip; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biodiversity; ecosystem functioning; benthic-pelagic coupling; niche; resource partitioning; competition; eutrophication; cyanobacterial blooms; diatoms; invasive species; Baltic Sea; Marine ecology; Marin ekologi; Marine Ecology; marin ekologi;

    Abstract : Animals living in marine sediments (the second largest habitat on earth) play a major role in global biogeochemical cycling. By feeding on organic matter from settled phytoplankton blooms they produce food for higher trophic levels and nutrients that can fuel primary production. READ MORE

  7. 5. Effects of contaminant mixtures on marine zooplankton diversity and function

    Author : Christina Jönander; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; zooplankton; copepods; ciliates; dinoflagellates; mixture toxicity; chemical mixtures; marine contaminants; biodiversity; reproduction; ULSFO; closed-loop scrubbers; exhaust gas cleaning systems;

    Abstract : Chemicals have important roles in our society and can be used as ingredients in personal care products, pesticides, pharmaceuticals, as well as be components of fuels used in cars or ships. More than 350 000 chemicals and mixtures have been registered for use, which only covers a part of all the chemicals that we may come into contact with. READ MORE
