Description

C:N ratios of the two 34C‐tolerant populations of Chaetoceros simplex and control and ancestral populations, at different temperatures.

Methods & Sampling

Chaetoceros simplex cultures, were obtained from population strain CCMP 200 (National Center for Marine Algae and Microbiota, NCMA).

C : N elemental analyses:
We measured the elemental composition of the two 34 °C‐tolerant populations and the control and ancestral populations, at different temperatures. From each culture during exponential growth, we filtered 10–20 mL duplicate subsamples onto pre‐combusted GF/F filters. The filters were then dried at 60 °C for 24 h, packed in aluminium tins and kept in a desiccator. Blanks were 10–20 mL of the medium filtered and processed as other samples. Particulate C and N were measured with a CHN analyzer (Costech ECS 4010) and ratios were calculated from weight percentage of each element after the subtraction of the corresponding blank.
