  text: 'We measured specific growth rates of Stephanodiscus minutulus, Nitzschia
    acicularis (diatoms), and Limnothrix redekei (cyanobacterium) under fluctuating
    and constant light in semi-continuous culture at 10°C, 15°C, and 20°C and under
    photoperiods of 6 h d−1 and 12 h d−1. Fluctuating light regimes simulated regular
    vertical mixing in lakes with a ratio of euphotic to mixed depth (zeu : zmix)
    of 1 and 0.5 on a cloudless day. Light fluctuations at zeu : zmix = 1 decreased
    the growth rates of S. minutulus, N. acicularis, and L. redekei by 18%, 33%, and
    29%, respectively, compared to constant light at the same daily light supply.
    Temperature had no effect on this decrease. Halving zeu : zmix (simulating deep
    mixing) had the same effect on growth as halving the photoperiod, demonstrating
    that these factors are cumulative. We introduce a simple empirical factor to adjust
    growth rates measured under constant light to account for fluctuating light. This
    factor is independent of temperature and photoperiod, applies over a range of
    zeu : zmix, and accurately describes present and published growth rates of several
    species. We show how to account for temporal variability of the light supply at
    different temperatures and photoperiods when predicting growth rates of phytoplankton.'
