Coral Reef Monitoring: From Cytological Parameters to Community Indices

Table 4

Results of regression between the ecological indices calculated for each transect of the fourteen stations of young coral communities. In each square the top figure is 𝑟² and the bottom is the 𝑃 value. Significant correlation (𝑃<0.05) is marked in bold.
