Extended Data Fig. 1 — (a) Examples of the availability of N in different chemical forms in reef waters that can be taken up by symbiotic corals. (b) Capacity of symbiotic coral to take up nitrogen in different chemical forms including dissolved free amino acids (DFAA). Bars represent the range of nitrogen availability and uptake capacity defined by the upper and lower boundary values deduced from the published literature. Relevant references and unit transformation measures are summarised in Extended Data Tables 1 and 2. Dissolved inorganic N (DIN) values provided in (a) are for (i) upwelling areas in which coral dominance is increased by 44% compared to comparable habitats with less exposure to internal wave driven upwelling and for (ii) reef waters in which the nutrient provision by seabirds results in elevated DIN values (up to >90% nitrate) and 3-fold increase growth Acropora formosa.
