Diurnal photosynthetic characteristics of Lithophyllum kotschyanum and Porolithon sp. Photosynthetic characteristics of the topside (black circles) and underside (open circles) of L. kotschyanum thalli and the upper surface of Porolithon sp. (black triangles) over a diurnal cycle: (a) maximum photochemical quantum yield (Fqˈ/Fmˈmax), (b) minimum saturation intensity (Ek, μmol photons m-2 s-1), (c) maximum relative electron transport rate (rETRmax, μmol electron m-2 s-1). Data presented as mean ± SE.
