Extended Data Fig. 6: The observed linear trend is sufficiently robust to the exclusion of low-abundance ASVs, coarse-graining at the family level, and the index used to measure microbial community diversity.

From: Resource–diversity relationships in bacterial communities reflect the network structure of microbial metabolism

Extended Data Fig. 6

a. Richness was calculated as the number of ASVs after the exclusion of those with relative abundance lower than 0.1%. b. Richness was calculated as the number of unique families in the media. c, d. The increase in diversity, measured as Shannon Entropy and Inverse Simpson Index, with the number of carbon sources can still be approximated by a line. These indices give progressively more weight to abundant species, accounting, in this way, for the evenness of the communities. In each panel, large colored dots indicate the mean ± s.e.m. while small grey dots indicate the average richness in each media containing a combination of resources (16 for single-resource, 24 for two-resource, 12 for four-resource, six for eight-resource, 16 for 15-resource and one for 16-resource combinations). Error bars are omitted for clarity.
