Extended Data Fig. 7: Biodiversity gradient with random species draws from a global pool retains the same relationship between species richness and the minimum amount of fish biomass to meet RDAs based on complementarity and selection.
From: Leveraging biodiversity to maximize nutrition and resilience of global fisheries
To build this random biodiversity gradient we sampled the global pool of species without replacement from 1 to 756 species, which is the species richness range for the number of food fishes available across nations. For every level of species richness, we performed this randomization 30 times for all 290 countries for a total of 8,700 random assemblages.
