  1. 1. Benthic use of phytoplankton blooms: uptake, burial and biodiversity effects in a species-poor system

    Detta är en avhandling från Stockholm : Department of Systems Ecology, Stockholm University

    Författare :Agnes M. L. Karlson; Stockholms universitet.; [2010]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biodiversity; ecosystem functioning; benthic-pelagic coupling; niche; resource partitioning; competition; eutrophication; cyanobacterial blooms; diatoms; invasive species; Baltic Sea; NATURAL SCIENCES Biology Terrestrial; freshwater and marine ecology Marine ecology; NATURVETENSKAP Biologi Terrestrisk; limnisk och marin ekologi Marin ekologi; marin ekologi; Marine Ecology;

    Sammanfattning : Animals living in marine sediments (the second largest habitat on earth) play a major role in global biogeochemical cycling. By feeding on organic matter from settled phytoplankton blooms they produce food for higher trophic levels and nutrients that can fuel primary production. LÄS MER

  3. 2. Influence of cyanobacterial blooms on coastal fish recruitment

    Detta är en avhandling från Växjö : Linnaeus University Press

    Författare :Karl-Johan Persson; Linnéuniversitetet.; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Akvatisk ekologi; Aquatic Ecology; Cyanobacteria; coastal fish recruitment;

    Sammanfattning : Cyanobacteria are the oldest oxygen-producing organisms on Earth and can be found in almost every terrestrial and aquatic habitat. Their long evolutionary history has enabled them to develop diverse adaptations in order to increase their survival in environments subjected to natural and anthropogenic changes. LÄS MER

  4. 3. Summer cyanobacterial blooms in the Baltic Sea - implications for copepod recruitment

    Detta är en avhandling från Stockholm : Department of Systems Ecology, Stockholm University

    Författare :Hedvig Hogfors; Stockholms universitet.; [2012]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cyanobacteria; Calanoid copepods; Food web interactions; Harmful algae blooms; Zooplankton; Nodularin; Allelopathy; Baltic Sea; Biochemical markers; RNA-based indices; Acidification; Global Climate Change; marin ekologi; Marine Ecology;

    Sammanfattning : During summer, the Baltic Sea is subjected to the world’s largest cyanobacterial blooms. These blooms are linked to eutrophication and raise many questions concerning their effects on the ecosystem. To understand their impacts on the food web dynamics, it is essential to assess growth responses of grazers to these cyanobacteria. LÄS MER

  5. 4. The effects of settling cyanobacterial blooms on meiofaunal assemblages of the Baltic Sea

    Författare :Francisco Nascimento; Stockholms universitet.; [2007]
    Nyckelord :;

  7. 5. Cyanobacterial Nitrogen Fixation in the Baltic Sea With focus on Aphanizomenon sp

    Detta är en avhandling från Stockholm : Department of Ecology, Environment and Plant Sciences, Stockholm University

    Författare :Jennie B. Svedén; Stockholms universitet.; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cyanobacteria; Baltic Sea; nitrogen fixation; Aphanizomenon sp.; dissolved nitrogen; particulate nitrogen; sedimentation; marin ekologi; Marine Ecology;

    Sammanfattning : Cyanobacteria are widely distributed in marine, freshwater and terrestrial habitats. Some cyanobacterial genera can convert di-nitrogen gas (N2) to bioavailable ammonium, i.e. perform nitrogen (N) fixation, and are therefore of profound significance for N cycling. LÄS MER
