The values are means ± s.d. and were constructed from in situ measurements performed using the submersible respirometer.
Abbreviations: α, initial slope; Ecom,compensation intensity; Ek, saturating intensity; Eopt, optimum irradiance; Pmax,light-saturated photosynthesis rate and compensation light levels; Pg/R24h, rate of gross photosynthesis to dark respiration integrated over 24 h.
