Figure 4

Redundancy costs and network distance. (A) Histogram of the fractional cost to be redundant for vein segment lengths, widths, surface area, volume and conductance for the 339 angiosperms leaves. Mean % cost values (Results) are the open symbols at the top of the panel and follow the legend for Figure 4b. (B) Mean distance to the network vs. mean distance to the MST (with red 1:1 line). A two sample t-test indicated that the mean values for the two methods did not differ in any case (p<0.05). Note, all data points are constrained to be below the 1:1 line.
