Extended Data Fig. 2: The species richness of an optimal portfolio (SOpt) increases as more RDAs are considered but never exceeds four species.

From: Leveraging biodiversity to maximize nutrition and resilience of global fisheries

Extended Data Fig. 2

Each point represents a country (n=291) colored by it’s biodiversity endowment (S). Increasing the number of RDAs considered also leads to an increase in the minimum portion size needed (Pmin), but more speciose portfolios are associated with lower Pmin. Box plots display the median (center line), interquartile range (box) and whiskers (minimum and maximum values within 1.5 × IQR).
