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

    University dissertation from Stockholm : Department of Systems Ecology, Stockholm University

    Author : Francisco J.A. Nascimento; Stockholms universitet.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Meiofauna; Cyanobacteria; competition; facilitation; ecosystems processes; NATURAL SCIENCES Biology Terrestrial; freshwater and marine ecology Marine ecology; NATURVETENSKAP Biologi Terrestrisk; limnisk och marin ekologi Marin ekologi; marin ekologi; Marine Ecology;

    Abstract : 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. READ MORE

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

    University dissertation from Stockholm : Department of Geological Sciences, Stockholm University

    Author : Stefano Bonaglia; Stockholms universitet.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nitrogen cycle; denitrification; DNRA; anammox; anoxia; hypoxia; eutrophication; meiofauna; macrofauna; aggregates; cyanobacteria; Baltic Sea; geokemi; Geochemistry;

    Abstract : 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. READ MORE

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

    University dissertation from Chalmers University of Technology

    Author : Fredrik J. Lindgren; Chalmers tekniska högskola.; Chalmers University of Technology.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Marin ekologi; Marine ecology; Toxikologi; Toxicology; Miljötoxikologi; Environmental toxicology; meiofauna; petroleum; bildanalys; subletala effekter; mikrobiellt samhälle; PAH;

    Abstract : 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. READ MORE

  4. 4. Dispersal in free-living, marine, benthic nematodes passive or active processes?

    University dissertation from Stockholm : Zoologiska institutionen

    Author : Jörgen Ullberg; Stockholms universitet.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nematod; dispersial; water column; choice; algal mats; disturbance; meiofauna; community; NATURAL SCIENCES Biology Terrestrial; freshwater and marine ecology; NATURVETENSKAP Biologi Terrestisk; limnisk och marin ekologi;

    Abstract : Meiofauna, and especially marine nematodes are common in sediments around the world. Despite very wide ranging distributions in many nematode species, little is presently known about their dispersal mechanisms shaping these patterns. Rafting, and perhaps ballast water transport has been suggested as viable means for nematode long-range transport. READ MORE

  5. 5. Evaluating effects of low concentrations of oil in marine benthic communities

    University dissertation from Chalmers University of Technology

    Author : Fredrik J. Lindgren; Chalmers tekniska högskola.; Chalmers University of Technology.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; oil; PAHs; meiofauna; microbial community; community response;

    Abstract : Large anthropogenic discharges of oil annually enter the marine environment, in the magnitude from large scale discharges to minor leakage, caused by ship collision accidents or seepage from urban areas. Possible detrimental environmental effects from these discharges differ, from acute lethal to chronic sub-lethal. READ MORE
