FIGURE 3.

Effect of coral bleaching on in vivo spectral scalar irradiance, E₀(λ) expressed in % of the incident downwelling irradiance, E_d(λ). Measurements were performed on the coenosarc (A,B) and polyp tissue (C,D) of P. damicornis (left panel), and Favites sp. (right panel). Solid and dashed lines represent measurements performed in aboral tissues and at the tissue surface, respectively. Measurements were performed on healthy corals (day 1; black) and bleached corals (day 10; gray). Data are mean ± SE (n = 6 corallite-level replicates).
