Comparing two classes of biological distribution systems using network analysis
Fig 4
Topological vs. physical edge-betweenness centrality.
(A) For each kind of network (displayed on the x-axis), the data shows the Spearman rank correlation coefficient ρ for the relationship between the topological edge betweenness centrality and the physical edge betweenness centrality
. The curly braces group the fungi (first 4 networks) and vasculature (last 2 networks). All networks exhibited significant positive rank correlations, but the displayed p-value from a two-sample t-test indicates that the mean rank correlation coefficient of the mycelial networks was significantly smaller than the mean rank correlation coefficient of the vasculature networks. (B) Topological edge betweenness centrality
vs. physical edge betweenness centrality
for the network with the highest Spearman correlation between these quantities (Mouse 5). (C) Topological edge betweenness centrality
vs. physical edge betweenness centrality
for the network with the lowest Spearman correlation between these quantities (R.B.). See the text for more details on these measures.
