Abstract

The provided data represent maximum growth rates of the temperate diatom Thalassiosira rotula obtained from the Harder Lab (University of Bremen; strain T. rotula_S16) and the polar diatom Thalassiosira gravida was obtained from the Norwegian culture collection of algae (NORCCA strain number UIO 478). Data were assessed in a nanocosm (microtiter-plate) 7-day multi-stressor laboratory experiment conducted in November 2022. The experimental design includes different combinations of temperature (4°C; 9°C; 13.5°C), photoperiod (4:20; 16:8; 24:0) and microbiome presence (xenic; axenic) at which growth was assessed to evaluate interactive effects of abiotic factors (temperature & photoperiod) and biotic facors (interactions with microbiome bacteria). Moreover, the code to process the data for statistical analysis is provided.
