Figure 5From: Convergent evolution of modularity in metabolic networks through different community structuresEnvironment variability and modularity. (Top row) On a small data set of 116 bacteria, habitat variability vs. normalized modularity (left) (Kruskal-Wallis H-test p = 5.48 × 10−11) and habitat variability vs. the number of enzymes (right) (Kruskal-Wallis H-test p = 1.03 × 10−10). (Bottom row) On a large data set of 806 microbes, habitat variability vs. normalized modularity (left) (Kruskal-Wallis H-test p=6.51×10−26) habitat variability vs. the number of enzymes (Kruskal-Wallis H-test p = 1.03 × 10−30).Back to article page
