## Trophic Incoherence ![[Trophic Coherence.png]] How likely is this graph to be topsortable? https://www.nature.com/articles/s41598-020-61196-8 Non-normality can be thought of as the degree of departure from symmetry in a network, while trophic coherence is a measure of how aligned the edges are in one direction. There is a conceptual similarity, and the two measures have been proven to be mathematically connected so that networks that have high trophic coherence are also highly non-normal ![[Topology and Trophic incoherence.png]]
