  1. 6. Introduced and indigenous macroalgae : Ecological effects, functions and regulating factors in tropical seascapes

    Författare :Maria Eggertsen; Christina Halling; Charlotte Berkström; Johan Eklöf; Jennifer Smith; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; macroalgae; introduced species; coral-algae interactions; nursery habitats; herbivory; Eucheuma denticulatum; tropical seascape; Marine Ecology; marin ekologi;

    Sammanfattning : Tropical marine shallow-water areas are highly productive systems that promote important ecological functions and biodiversity. Stressors on these systems are intensifying due to increasing anthropogenic disturbances on multiple scales. LÄS MER

  3. 7. Aspects of offshore renewable energy and the alterations of marine habitats

    Författare :Dan Wilhelmsson; Sören Nylin; Anders Persson; Stockholms universitet; []
    Nyckelord :renewable energy; biodiversity; wave power; wind power; disturbance; fish; fouling organisms; artificial reefs; zoologisk ekologi; Animal Ecology;

    Sammanfattning : Several Western European countries are planning for a massive offshore renewable energy (i.e. wind and wave energy) development (ORED) along the European Atlantic coast and in the Baltic Sea. LÄS MER

  4. 8. 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

  5. 9. Evolution of annelid diversity at whale-falls and other marine ephemeral habitats

    Författare :Helena Wiklund; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Whale-fall; cryptic species; Dorvilleidae; Chrysopetalidae;

    Sammanfattning : When whales die and sink to the sea-floor, they provide a sudden, enormous food supply to organisms in the vicinity. At first, larger mobile scavengers remove the flesh, but also when only the bones remain, the whale-fall can still sustain macrofauna communities for several years. LÄS MER

  7. 10. Round goby Neogobius melanostomus in the Baltic Sea – Invasion Biology in practice

    Författare :Gustaf Almqvist; Magnus Appelberg; Sture (biträdande) Hansson; Johanna Mattila; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Round goby; Neogobius melanostomus; Apollonia melanostoma; non-indigenous fish; life history characteristics; predation; competition; Gulf of Gdańsk; Baltic Sea.; Marine ecology; Marin ekologi; marin- och brackvattensekologi; Marine and Brackish Water Ecology;

    Sammanfattning : Human mediated transfer of non-indigenous species is considered to be a major threat to global biodiversity. The Ponto-Caspian round goby (Neogobius melanostomus), which has established populations in various regions in Eurasia and North-America, was first observed in Gulf of Gdańsk, Baltic Sea, in 1990.
