  1. 1. Trophic ecology of meiofauna : Response to sedimentation of phytoplankton blooms in the Baltic Sea

    Författare :Francisco J.A. Nascimento; Ragnar Elmgren; Richard Warwick; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Meiofauna; Cyanobacteria; competition; facilitation; ecosystems processes; Marine ecology; Marin ekologi; Marine Ecology; marin ekologi;

    Sammanfattning : Marine soft sediments are the second largest habitat on Earth. How animal communities in this habitat are structured is a central issue in marine ecology. Food is an important limiting factor for many benthic populations, and settling organic matter from phytoplankton blooms is of vital importance to them. LÄS MER

  3. 2. The benthic meiofauna of three coastal areas : structure, seasonal dynamics and response to environmental perturbations

    Författare :Bertil Widbom; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Marine biology; Benthos; Meiofauna;

    Sammanfattning : .... LÄS MER

  4. 3. Control factors of the marine nitrogen cycle : The role of meiofauna, macrofauna, oxygen and aggregates

    Författare :Stefano Bonaglia; Patrick Crill; Volker Brüchert; Per Hall; Chritoph Humborg; Risgaard-Petersen Nils; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nitrogen cycle; denitrification; DNRA; anammox; anoxia; hypoxia; eutrophication; meiofauna; macrofauna; aggregates; cyanobacteria; Baltic Sea; geokemi; Geochemistry;

    Sammanfattning : The ocean is the most extended biome present on our planet. Recent decades have seen a dramatic increase in the number and gravity of threats impacting the ocean, including discharge of pollutants, cultural eutrophication and spread of alien species. LÄS MER

  5. 4. Microbenthos under Pressure : Impacts of human activities on bacteria and meiofauna communities in Baltic soft sediments

    Författare :Sven Iburg; Francisco J. A. Nascimento; Owen Wangensteen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; soft sediments; benthic ecosystems; anthropogenic disturbance; contamination; recreational boating; bottom trawling; meiofauna; bacteria; metabarcoding; Baltic Sea; mjuka sediment; bentiska ekosystem; antropogenisk påverkan; förorening; fritidsbåtar; bottentrålning; meiofauna; bakterier; metabarcoding; Östersjön; marin ekologi; Marine Ecology;

    Sammanfattning : The marine benthic zone is one of the largest habitats on the planet, harbouring a large diversity of life that underpin many important ecological processes. However, these habitats have been under growing stress from human activities, profoundly altering their living communities. LÄS MER

  7. 5. Assessing Sub-Lethal Impacts of Petroleum Compounds on Marine Benthic Systems

    Författare :Fredrik Lindgren; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; subletala effekter; mikrobiellt samhälle; meiofauna; petroleum; PAH; bildanalys;

    Sammanfattning : Petroleum and its different distillates commonly end up in the marine environment. One source of these additions is discharges originating from shipping activities; accidents, ship wrecks, operational spills etc. LÄS MER
