Appendix S1: Tissue nutrient data from T. ornata collected at Gump Reef and Sailing School
3
Reef.
4
Methods. T. ornata thalli were collected from our two sites, Gump and Sailing School reefs, to
5
evaluate nitrogen and phosphorous content. 10 samples of algae from each site were rinsed in
6
freshwater, dried at <60°C, ground with a mortar and pestle, and sent to the University of California
7
Davis Isotope Facility.
8
Results. Tissue nutrients, nitrogen and phosphorous, by percentage of dry weight were
9
significantly higher for T. ornata collected from Gump than Sailing School Reef (see Figures S1 and
10
S2 below).
