Stony Coral Indicators. Indicator values for stony corals at 60 stations (25 m2 transect areas) across southern Puerto Rico. (A) Rarefaction curve showing the number of additional stony coral species found with each additional station surveyed. (B-F) Distribution of values across stations expressed as a percentage of the area sampled (± SE) for taxa richness, colony density, average colony surface area in a transect (m2), total coral cover (m2 surface area m−2 substrate), and live coral cover (m2 live tissue surface area m−2 substrate). Surface area and cover calculations were based on 3D estimates of colony size. Note that abscissa ranges in D-F are not regular.
