Comparison of Rentian scaling analysis in the mycelial networks and vasculature networks.

In each panel, the x-axis labels the kind of network, with the curly braces grouping the mycelia (first 4 networks) and the vasculature (last 2 networks). The y-axis measures the value of a given property for each network. A p-value is displayed if there was 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 normalized topological Rent exponent was significantly smaller in the population of mycelial networks compared to the population of vasculature networks. (B) The normalized physical Rent exponent was significantly larger in the population of mycelial networks compared to the population of vasculature networks. (C) The ratio pmin/p of the theoretical minimum physical Rent exponent to the true physical Rent exponent was signficantly smaller in the population of mycelial networks compared to the population of vasculature networks. See the main text for more details on each measure.
