Allometry and Dissipation of Ecological Flow Networks

Figure 1

Comparison of different methods for calculating the allometric scaling of a hypothetical ecological flow network.

(a) is a hypothetical network (the letter in each node is its index). The black node is the root, the numbers besides edges stand for flows, and the dashed lines represent dissipations; (b) shows the , and values inside and beside node , respectively, by our method; (c) is a spanning tree of (a), and the numbers inside and beside vertex are the and values calculated by Garlaschelli's method; (d) is the implicated flow network of (c), and the numbers beside the edges are the flux values.
