Extended Data Fig. 3: The wider aggregate nutrient trait content variation in more biodiverse countries increased the potential to assemble optimal species portfolios or select single best species with nutritionally extreme values.

(A) Species from countries with higher biodiversity exhibit more variation in nutrient content, measured as the convex hull volume considering six key nutrients derived from fish. (B) The mean nutrient trait distance of all species within a country tends to be lower than the mean nutrient trait distance of species in optimal portfolios (the black line represents the 1:1 line, with points above representing countries where the mean nutrient trait distance of optimal species is larger than of all species within that respective country). (C) The mean nutrient trait distance of all species within a country tends to be lower than the mean nutrient trait distance of single best species (the black line represents the 1:1 line, with points above representing countries where the mean nutrient trait distance of the single best species is larger than of all species within that respective country). Each point corresponds to a country (n=290).
