Physiological responses of sponges to light conditions.
(a) Percentage buoyant weight change (note: y-axis scales differ between species), and (b) Chlorophyll a concentrations, for the five species, after the 28 d experimental period and 14 d observational period (mean ± SE). Asterisks show statistically significant differences between the experiment and recovery phase (T-tests: P < 0.05). Light treatments include 0, 0.8, 3.2, 8.1 mol photons m−2 d−1 and natural light (NL, 3.2–6.5 mol photons m−2 d−1).
