Comparison of environmental characteristics at the research sites Buoy 0 and Playa Kalki.

Comparison of coral cover (± s.d.), total algal cover (including macroalgae, turf algae and benthic cyanobacteria), cover by the macroalga L. variegata, dissolved nutrient concentrations and N:P ratios at the coral reef ecosystems of Buoy 0 and Playa Kalki. The data were collected at 20 m depth. Differences between the two research sites were tested with the Mann-Whitney U Test using a significance level of P<0.05; n1 and n2 indicate the samples sizes at Buoy 0 and Playa Kalki, respectively. Significant P-values are indicated in bold.
