a After at least 3.5 h of growth in steady Clow, cells experience the onset of nutrient fluctuations (T = 60 min) between Clow and Chigh. The growth rate dynamics in response to each successive nutrient period transition from the dynamics observed in response to a single shift to those observed in fluctuating environments (Fig. 4b). The growth rate dynamics of the successive periods, including the 60 min preceding the first nutrient upshift (period 0), are overlaid to show the stabilization of the growth rate signal. Shaded error bars denote the standard deviation of the mean among replicate experiments (n = 3). b Stabilization of growth rate dynamics with successive nutrient periods. The mean growth rate following each downshift (half-period in Clow, tlow), each upshift (half-period in Chigh, thigh) and across the full period (T) adjusts and stabilizes by the third period. Error bars denote the standard error of the mean (n = 3) and are smaller than points when not visible.
