  1. 6. Dispersal in free-living, marine, benthic nematodes : passive or active processes?

    Författare :Jörgen Ullberg; Emil Ólafsson; John Lambshead; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nematod; dispersial; water column; choice; algal mats; disturbance; meiofauna; community; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

    Sammanfattning : 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. LÄS MER

  3. 7. Benthic-pelagic coupling in a changing world : Structural and functional responses of microbenthic communities to organic matter settling

    Författare :Séréna Albert; Francisco J. A. Nascimento; Monika Winder; Stefano Bonaglia; Tom Moens; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Soft sediments; benthic-pelagic coupling; organic matter export; meiofauna; nitrogen cycle; metabarcoding; Baltic Sea; Marine Ecology; marin ekologi;

    Sammanfattning : Marine soft sediments form the second largest habitat on the planet. Organisms residing in this environment represent a vast reservoir of biodiversity, and play key roles in ecosystem processes. LÄS MER

  4. 8. Evaluating effects of low concentrations of oil in marine benthic communities

    Författare :Fredrik Lindgren; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; PAHs; community response; microbial community; oil; meiofauna;

    Sammanfattning : 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. LÄS MER

  5. 9. Ecological aspects of soft bottom meiofauna in Eastern Africa

    Författare :Simon Ndaro; Magda Vincx; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; zoologi; Zoology;

    Sammanfattning : The meiobenthos is numerically the most abundant metazoan group in shallow water habitats. While the meiobenthos characteristically shows variable distribution, the causal factors controlling this variation remain poorly understood. LÄS MER
