Fig. 2.
The mean difference between atom % enrichment of carbon (a, b) and nitrogen (c, d) observed between Symbiodinium and their Orbicella faveolata hosts after 10 h exposure to H13CO3− and 15NO3− and following a 10 day incubation at ambient (26 °C) and elevated (31 °C) temperature. Points represent the mean +/− standard error of 10 replicate samples collected from the shallow (1 m; dominated by ITS2 phylotype A3) and deep (15 m; dominated by ITS2 phylotype C7) fore-reef at Carrie Bow Cay, Belize pooled from 2 replicated experiments. * indicates a significant difference between the temperature treatments as determined by Student’s t test
