Comparing two classes of biological distribution systems using network analysis
Fig 3
Comparison of topological network metrics between the mycelial and vasculature systems.
In each panel, the x-axis labels the kind of network, with the curly braces grouping the mycelia (first 4 networks) and vasculature (last 2 networks). The y-axis measures the value of a given property for each network. A p-value is displayed if we found a statistically significant difference (as determined by a two-sample t-test) in the mean value of the given property between the population of mycelial networks and the population of vasculature networks. (A) The mean degree 〈k〉 was significantly larger in the fungi compared to the vasculature. (B) The normalized clustering coefficient was significantly larger in the fungi compared to the vasculature. (C) The alpha index α was significantly larger in the fungi compared to the vasculature. (D) The normalized topological efficiency
was significantly larger in the vasculature compared to the fungi. See the main text for more details on each measure.
