Abstract

Maximum excitation pressure of Symbiodinium assemblages was assessed as an indicator for holobiont photosynthetic performance of Pocillopora damicornis in shallow (1-2m), back reef and P. eydouxi in deeper fore reef (>3m).

Maximum excitation pressure of Symbiodinium assemblages was assessed as an indicator for holobiont photosynthetic performance of Pocillopora damicornis in shallow (1-2m), back reef and P. eydouxi in deeper fore-reef (>3m). Effective quantum yield (F/Fm’) was measured using a Walz Diving Pam Fluorometer (Germany) via saturation pulse fluorometry at 1cm away from branch tips during midday. Maximum quantum yield (Fv/Fm) was measured under custom shading devices which were designed to dark-acclimate corals in situ for 30 minutes. Maximum excitation pressure (Q) was calculated using the formula, Q = 1-(F/Fm’)/(Fv/Fm).
