<i>In hospite</i> net photosynthesis-irradiance (P-E) curves from four Caribbean gorgonian species.

<p>(A) P-E curves per cm² of gorgonian branches and, (B) P-E curves per <i>Symbiodinium</i> cell. Solid lines represent the average fitted values for <i>Pterogorgia anceps</i> (n = 9), <i>Eunicea tourneforti</i> (n = 8), <i>Pseudoplexaura porosa</i> (n = 6), and <i>Pseudoplexaura wagenaari</i> (n = 6). Dotted lines represent ± standard error. The photosynthetic rate at 1800 µmol quanta was used as a proxy for the maximum photosynthetic rate.
