We tested the antagonistic effects of three strains of the dinoflagellate HAB species Alexandrium catenella on three target species (the chlorophyte Tetraselmis sp., the... -
Experimental phosphate limitation in Nodularia spumigena CCY9414
Nodularia spumigena is a toxic, filamentous cyanobacterium capable to fix atmospheric nitrogen, which is often dominating cyanobacterial bloom events in the Baltic Sea and other... -
Influence of temperature, pCO2, and dissolved nutrients on the oxidative stre...
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... -
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... -
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... -

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 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... -

Strong shift from HCO3- to CO2 uptake in Emiliania huxleyi with acidification...
Effects of ocean acidification on Emiliania huxleyi strain RCC 1216 (calcifying, diploid life-cycle stage) and RCC 1217 (non-calcifying, haploid life-cycle stage) were... -
Impact of elevated pCO2 on paralytic shellfish poisoning toxin content and co...
Ocean acidification is considered a major threat to marine ecosystems and may particularly affect primary producers. Here we investigated the impact of elevated pCO2 on... -
