  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; Ragnar Elmgren; Carlo Heip; [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; Catherine Legrand; Markku Viitasalo; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cyanobacteria; coastal fish recruitment; Akvatisk ekologi; Aquatic Ecology;

    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; Sture Hansson; Wim Kimmerer; [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. Managing Eutrophic Waters in Artificial Recharge Plants : Cyanotoxin risk in Swedish freshwaters

    Detta är en avhandling från Department of Water Resources Engineering, Lund Institute of Technology, Lund University

    Författare :Jing Li; [2020-03-27]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Drinking water; cyanobacterial blooms; cyanotoxins; nutrients; total phosphorus; DIN TP; quick test kit;

    Sammanfattning : In the last decades, the frequency and intensity of cyanobacterial blooms have been of increasing concern. They have become a direct threat to the drinking water supply by clogging filters, bringing odour and unpleasant taste to the treated water and worst of all, causing elevated cyanotoxins, which can be difficult to remove, yet lead to severe health issues.
