    Swimming speed of two phytoplankton species, Rhodomonas salina and Teleaulax sp., and the heterotrophic dinoflagellate Oxyrrhis marina (2020)
    PANGAEA
    In:  Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research, Bremerhaven
    Details
    Publication Date: 2023-03-16
    Description: Swimming speed of two phytoplankton species, Rhodomonas salina and Teleaulax sp., grown in nutrient replete F/2 medium and in P-limited conditions, as well as swimming speed of the heterotrophic dinoflagellate Oxyrrhis marina either starved or fed with these four types of phytoplankton individually. In addition to the different culture and feeding conditions, the phytoplankton and dinoflagellates were incubated with the water from differently cultured organisms.

    (Supplement 3) Selective feeding of dinoflagellate in the FlowCam experiment (2021)
    PANGAEA
    Details
    Publication Date: 2023-01-13
    Description: This dataset comprises data from two experiments analysed with two different tools, a FlowCam and a microscope. The heterotrophic dinoflagellate Oxyrrhis marina was subjected to different feeding treatments (starved, or fed with either F/2 nutrient reach, nitrogen-limited, or phosphorus-limited phytoplankton of the species Rhodomonas salina). The carbon:nitrogen:phosphorus stoichiometry of the different phytoplankton and dinoflagellate cultures was measured. The nitrogen-limited and phosphorus-limited phytoplankton were mixed and the mixture was offered as food to the dinoflagellates previously fed on either nitrogen-limited, or phosphorus-limited phytoplankton. The selective feeding of the dinoflagellate on the two mixed algal qualities was measured.

    Mesocosm experiment 2013 on effects of increased CO2 concentration on nutrient limited coastal summer plankton: Microzooplankton biovolume (2021)
    PANGAEA
    Details
    Publication Date: 2023-02-24
    Description: Aquatic ecosystems face a multitude of environmental stressors, including warming and acidification. While warming is expected to have a pronounced effect on plankton communities, many components of the plankton seem fairly robust towards realistic end-of-century acidification conditions. However, interactions of the two stressors and the inclusion of further factors such as nutrient concentration and trophic interactions are expected to change this outcome. We investigated the effects of warming and high CO2 on a nutrient-deplete late summer plankton community from the Kiel Fjord, Baltic Sea, using a mesocosm setup crossing two temperatures with a gradient of CO2. Phytoplankton and microzooplankton (MZP) growth rates as well as biomass, taxonomic composition, and grazing rates of MZP were analysed. We observed effects of high CO2, warming, and their interactions on all measured parameters. The occurrence and direction of the effects were dependent on the phytoplankton or MZP community composition. In addition, the abundance of small-sized phytoplankton was identified as one of the most important factors in shaping the MZP community composition. Overall, our results indicate that an estuarine MZP community used to strong natural fluctuations in CO2 can still be affected by a moderate increase in CO2 if it occurs in combination with warming and during a nutrient-deplete post-bloom situation. This highlights the importance of including trophic interactions and seasonality aspects when assessing climate change effects on marine zooplankton communities.
