Figure 4

(a) The nodes are ordered according to the stationary distribution of the random walkers calculated from (9), and the hierarchy levels are corresponding to groups of nodes for which the standard deviation of Inline graphic is at most 0.125 ⋅ σ(pstat), where σ(pstat) denotes the standard deviation of Inline graphic over the whole network. The colour coding of the nodes reflects their effective trophic level published in36. (b) Listing of the abbreviations used in (a).
