Abstract

Daily growth rates for Thermal Performance Curve (TPC) of Chaetoceros simplex in nitrogen-replete evolved populations after about 200 generations of evolution at eight temperatures, 10-35 degrees C.

Daily growth rates for Thermal Performance Curve (TPC) of Chaetoceros simplex in nitrogen-replete evolved populations after about 200 generations of evolution at eight temperatures, 10-35 degrees C.

After ~ 200 generations of evolution (165–186 days: 194–232 generations), we characterised the TPCs of two randomly selected N‐replete evolved populations that were 34 °C‐tolerant (see the 34 °C challenge section below) and the control and an ancestral population. Assay temperatures were 10, 20, 25, 29, 31, 32, 34 and 35 °C, and three replicate populations were grown in 50‐mL culture flasks (instead of well plates) (96 growth rate estimates).
