From: Linking host morphology and symbiont performance in octocorals
Relationships between the number of symbiont cells per polyp and the photosynthetic performance of the different octocoral species, normalized by symbiont density (sea fan- dark grey circle, sea plumes- black circles, sea whips- grey circles, sea rods- white circles). Exponential relationship between symbiont density and (a) maximum photosynthetic rate (R2 = 0.82, y = 1.32 + 1.99(−133.2x), p = 0.0061) and (b) photosynthetic efficiency (R2 = 0.92, y = 0.0021 + 0.0046(−230.5x), p = 0.0008). Data represent means ± SE (n = 6).
