Representation of the trophic network of the Celtic Sea in the isotopic space with sensitivity to fishing (size of the dots) and centrality (color scale from dark blue to light green). The isotopic space is defined by isotopic ratio of carbon 13C and nitrogen 15N. The nitrogen axis is consistent with species trophic level while the carbon axis discriminates pelagic (more negative) from benthic (less negative) pathways. Full names of the taxa are given in Table S1.
