Fig. 2. Changes in the (A) dark-adapted quantum yield (18:00 h) and (B)
Symbiodinium cell density within the coral Acropora aspera
during a simulated bleaching event. Coral colonies preheated 2 weeks prior
(H2; filled circles), 1 week prior (H1; filled
triangles), not preheated (H0; open diamonds), and controls (open
squares) are indicated. Error bars, although not always visible, represent
± s.e.m., N=10. *Significant difference
