Elemental content plotted as elemental ratios normalised to phosphorus (E:P), of the ten Symbiodiniaceae isolates at 27.4°C. Data is mol:mol for macronutrients (C, N, S, K and Ca) and mmol:mol for micronutrients (V, Mn, Fe, Ni, Cu, Zn, Se, S, Mo). Lower and upper hinges of each boxplot correspond to the first and third quartiles, and 50% to the median. The upper and lower whiskers of each boxplot extend from the hinge to the largest and smallest value up to 1.5 × the inter-quartile range, respectively
