From: Seabird nutrients increase coral calcification rates and boost reef carbonate production

Coral cover and reef-scale coral carbonate production rates. (A) Coral cover (%); Reef-scale coral carbonate production calculated (B) using average coral growth rates and skeletal densities at both sites, (C) using site-specific linear growth rates and skeletal density values for submassive Isopora palifera and corymbose Acropora vermiculata, and (D) using the same coral growth rates for both sites (as in C low seabird) but multiplying carbonate production at the high seabird site with 2.2 (mean difference in calcification across both species). Boxes represent the median and the interquartile range (IQR), with whiskers extending to 1.5 times the IQR and outliers represented by points. White diamonds indicate the mean values for each group.
