Fig. 5. Scaling laws for individuals and ecosystems are statistically distinguishable for some network and catalytic diversity measures.

Shown are the results of a permutation test to determine whether properties of biochemical networks constructed from individual genomes scale differently than those constructed from metagenomes (ecosystems). For each network measure, the test statistic is shown as a vertical dashed line, while the null distribution is shown as a solid line (see “Fitting network measure scaling and permutation tests” section in Materials and Methods on for more details). Blue squares indicate that the scaling behavior is indistinguishable between levels of organization, while green squares show measures that can distinguish scaling of individuals from that of ecosystems.
