  1. 1. Effects of Marine Protected Areas on Tropical Seagrass Ecosystems

    Författare :Elisa Alonso Aller; Johan S Eklöf; Charlotte Berkström; Martin Gullström; Glenn Hyndes; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; coastal ecosystems; seagrass; marine protected areas; management; conservation; fish; herbivory; Western Indian Ocean; East Africa; tropical; Marine Ecology; marin ekologi;

    Sammanfattning : Seagrass beds are highly productive coastal ecosystems that sustain a rich and diverse associated fauna and flora. Increasing anthropogenic pressures threaten seagrass ecosystems and have already led to major seagrass losses across the world. LÄS MER

  3. 2. 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?

    Författare :Angelica Chirico; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; marin ekotoxikologi; Marine Ecotoxicology;

    Sammanfattning : 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. LÄS MER

  4. 3. Effects of community- and government-managed marine protected areas on tropical seagrass and coral communities

    Författare :Angelica Chirico; Johan Eklöf; Nils Kautsky; Even Moland; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; coastal ecosystems; conservation; marine spatial planning; locally managed; fisheries closure; benthic communities; fish; foundation species; macroalgae; secondary succession; life-history; trait variability; plasticity; tourism; human disturbance; fishing; experimental research; Western Indian Ocean; causal modelling; structural equation model; permanova; multivariate data; marin ekotoxikologi; Marine Ecotoxicology;

    Sammanfattning : Tropical seagrass beds and coral reefs are among the most productive and diverse ecosystems on Earth and provide ecosystem services, such as fish production and coastal protection, and support livelihoods of millions of people. At the same time, these ecosystems are threatened globally by anthropogenic disturbances, such as overfishing, pollution and global warming. LÄS MER

  5. 4. Marine environmental governance and management in Sweden from the 1960s until today : Did the actions suit the needs?

    Författare :Kjell Grip; Sven Bolmqvist; Kjell Larsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; International programmes on ocean and seas; Baltic Sea; Kattegat-Skagerrak; Marine spatial planning and management; Marine Ecology; marin ekologi;

    Sammanfattning : This thesis investigates how governance and management relevant to the use and protection of the marine environment has emerged in Sweden from the 1960s until today. Focus is on how the modern environmental and nature conservation administration in Sweden developed the legal and organizational frameworks needed for proper management. LÄS MER

  7. 5. Applications of ocean transport modelling

    Författare :Hanna Corell; Kristofer Döös; Björn Kjerfve; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ocean transport modelling; connectivity; particle-tracking; sediment transport; Forsmark; marine protected areas; MPA; stream functions; heat flux; wind forcing; Carcinus maenas; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Sammanfattning : The advective motion of seawater governs the transport of almost everything, animate or inanimate, present in the ocean and those lacking the ability to outswim the currents have to follow the flow. This makes modelling of advective ocean transports a powerful tool in various fields of science where a displacement of something over time is studied. LÄS MER
