  1. 1. Ciliates in marine food webs : behaviours structuring plankton communities

    Författare :Mona Johansson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Infusionsdjur; Plankton;

    Sammanfattning : .... LÄS MER

  3. 2. Ecological niche dynamic, lessons from plankton

    Författare :Baptiste Serandour; Monika Winder; Thorsten Blenckner; Eric Goberville; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plankton; Metabarcoding; Spatial distribution modeling; Ecological niche; Climate Change; marinbiologi; Marine Biology;

    Sammanfattning : Abiotic conditions shape biological communities around the globe. Through spatial and temporal heterogeneity, environments impact plankton physiology, phenology and distribution. LÄS MER

  4. 3. Nutrient limitation and elemental ratios in Baltic Sea plankton

    Författare :Jakob Walve; Karin Lochte; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plankton; Östersjön; Ekosystem i vatten; Systems Ecology; systemekologi;

    Sammanfattning : Phytoplankton growth is frequently limited by the supply of nitrogen (N), phosphorus (P), or sometimes other elements. N2-fixing cyanobacteria are favoured by N limitation, which they may alleviate by adding new N to the ecosystem. LÄS MER

  5. 4. The importance of terrestrial carbon in plankton food webs

    Författare :Cesar Bolivar Daniel; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Ecology; lakes; carbon; zooplankton; Spumella elongata; Poterioochromonas malhamensis; flagellates; bacteria; stable isotopes; photochemistry; autochthonous; DOC; allochthonous; plankton; Ekologi; Hydrobiology; marine biology; aquatic ecology; limnology; Marinbiologi; limnologi; akvatisk ekologi;

    Sammanfattning : Allochthonous substances, i.e. produced in terrestrial ecosystems, are known to fuel bacterial production in humic lakes. I observed that allochthonous carbon subsidizes bacteria even at high levels of phytoplankton biomass. LÄS MER
