Fig. 2. Chances that a pooled dataset contains at least one subgroup with overlapping isotopic niches as a function of the difference between the mean isotopic values of the two considered groups (Host and Symbionts).

Fig. 2

The curves correspond to different levels of SD associated with the means of the pooled fractions. Niche segregation is deduced from the P value of Hotelling tests (P > 0.05) for 182,000 simulated data per SD. Dotted line represents the values obtained for Platygyra sp. [ΔMean δ15N(Host-Symb) = 2.5‰ and ΣSD(Host-Symb) = 2].
