What constrains food webs? A maximum entropy framework for predicting their structure with minimal biases
Fig 2
Prediction errors of the relative number of predators and prey.
The relative number of predators (kin) is plotted against the relative number of prey (kout) for each species in all (a) empirical and (b) predicted joint degree sequences. The predicted joint degree sequences were obtained after sampling one realization of the joint degree distribution of maximum entropy for each network while keeping the total number of interactions constant. (c) Difference between predicted and empirical values when species are ordered according to their total degree. Due to significant data overlap, all relationships are represented as 2D histograms. The color bar indicates the number of species that fall within each bin.
