  2. 1. Marine Seaweed Invasions : the Ecology of Introduced Fucus evanescens

    Author : Sofia A. Wikström; Lena Kautsky; Ove Eriksson; Paul Lavery; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biological invasions; marine; seaweed; algae; herbivory; enemy release hypothesis; phlorotannins; anti-fouling; Fucus evanescens; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

    Abstract : Biological invasions are an important issue of global change and an increased understanding of invasion processes is of crucial importance for both conservation managers and international trade. In this thesis, I have studied the invasion of the brown seaweed Fucus evanescens, to investigate the fate and effect of a perennial, habitat-forming seaweed introduced to a coastal ecosystem.

  4. 2. Marine seaweed invasions : Impacts and biotic resistance in native ecosystems

    Author : Josefin Sagerman; Sofia Wikström; Fransisco Arenas; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plant invasion; exotic species; generalist herbivores; plant-herbivore interactions; enemy-release hypothesis; ecosystem function; marin ekotoxikologi; Marine Ecotoxicology;

    Abstract : Marine seaweeds constitute one of the most productive plant systems known on Earth and a rich fauna including juvenile fish and crustaceans is dependent on the habitats they form. Human influence on marine costal ecosystems has resulted in large scale changes to the abundance and distribution of species, where species introductions constitute an obvious part. READ MORE

  5. 3. Importance of blue mussels for biodiversity and ecosystem functioning in subtidal habitats

    Author : Pia Norling; Nils Kautsky; Tom Ysebaert; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; blue mussel; Mytilus spp.; ecosystem engineering; habitat-modifier; diversity; facilitation; ecosystem functioning; ecosystem services and water quality maintenance; Marine ecology; Marin ekologi; marin ekotoxikologi; Marine Ecotoxicology;

    Abstract : Blue mussels, Mytilus spp., occur on rocky and sedimentary shores worldwide where they often form dense aggregates. These assemblages change the local environment and create unique habitats. READ MORE

  6. 4. 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

  7. 5. Scaling Marine and Water Management

    Author : Aron Westholm; Göteborgs universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Ecosystem approach; Marine management; Freshwater management; Legal geography; Marine spatial planning; Municipal planning; Water planning; Environmental law; Environemnatal management; Environmental governance; Adaptive law; Adaptive management;

    Abstract : This book is concerned with the linkages between legal systems and the complexity of nature. It explores how legal delimitations of ecosystems and diffusion of management across different levels of administration affects priorities and outcomes of natural resource management. READ MORE
