We tested the antagonistic effects of three strains of the dinoflagellate HAB species Alexandrium catenella on three target species (the chlorophyte Tetraselmis sp., the... -
Seawater carbonate chemistry and coccolithophores and diatoms resilient to oc...
Here, we investigatethe impacts of moderate (~700 μmol/kg) and high (~2700 μmol/kg) limestone-inspired alkalinity additionson two biogeochemically and ecologically important... -
Seawater carbonate chemistry and oxidative stress response, carbon metabolism...
We conducted a full-factorial lab experiment to study the individual and combined effects of temperature (18°C and 21°C), pCO2 (400 and 1000 ppm), and dissolved N:P ratio (16... -
Seawater carbonate chemistry and Phaeocystis pouchetii's responses to tempera...
We assessed the responses of solitary cells of Arctic Phaeocystis pouchetii (Strain PS78) grown under a matrix of temperature (2°C vs. 6°C), light intensity (55 vs. 160 μmol... -
Seawater carbonate chemistry and population-specific responses in physiologic...
Although coccolithophore physiological responses to CO2-induced changes in seawater carbonate chemistry have been widely studied in the past, there is limited knowledge on the... -
Seawater carbonate chemistry and the intrinsic and extrinsic phenotypic chara...
Ocean acidification (OA) has important effects on the intrinsic phenotypic characteristics of many marine organisms. Concomitantly, OA can alter the extended phenotypes of these... -
Temperature responses of different functional traits in Arctic phytoplankton
This study was conducted in autumn/winter 2021/2022 at the laboratory of the Alfred-Wegener-Institute Bremerhaven. To assess temperature response patterns of various functional... -
Results of a 24-hour laboratory experiment sampling cell concentrations, part...
Cell division of the coccolithophore Emiliania huxleyi and other phytoplankton typically becomes entrained to diel light/dark cycles under laboratory conditions, with division... -
Diatom specific growth rates based on cell concentrations and PDMPO staining
While in culture, specific growth rate (μ) can be easily determined through cell counts (N0 and Nt). This is not the case for incubations with natural assemblages, where grazers... -
Diatom cell counts and concentrations during fluorophore PDMPO incubation
To ensure balanced growth and stable conditions, all cultures were acclimated in semi-continuous batch cultures for at least nine generations before starting the experiments.... -

Seawater carbonate chemistry and growth, production rates, and cellular compo...
Arctic phytoplankton and their response to future conditions shape one of the most rapidly changing ecosystems on the planet. We tested how much the phenotypic responses of... -
Differing responses of three Southern Ocean Emiliania huxleyi ecotypes to cha...
The invasion of anthropogenic carbon dioxide into the surface ocean is altering seawater carbonate speciation, a process commonly called ocean acidification. The high latitude... -
Temperature affects the morphology and calcification of Emiliania huxleyi str...
The global warming debate has sparked an unprecedented interest in temperature effects on coccolithophores. The calcification response to temperature changes reported in the... -
Negative effects of ocean acidification on calcification vary within the cocc...
A large percentage of CO2 emitted into the atmosphere is absorbed by the oceans, causing chemical changes in surface waters known as ocean acidification (OA). Despite the high...
