Isotopic and trophic niche metrics of Adamussium colbecki and Sterechinus neumayeri at each depth (shallow: 15–25 m; deep: 50–150 m) and in the long term (Tissue, based on analysis of soft tissues) and short term (Gut, based on analysis of gut contents). TA: total isotopic niche area; SEAc: standard ellipse area corrected for degrees of freedom. MNDintra and MNDinter: intra- and inter-specific mean isotopic distance between specimens respectively. Hs: trophic niche width calculated as the Shannon diversity of resources consumed at both population (pop) and individual (ind) level. π: degree of intraspecific diet differentiation (see materials and methods). E: degree of coupling of the energy channels (sediment, benthic, pelagic, and sympagic producers) in the food web, ranging from 0 (consumers feeding on one channel only) to 1 (consumers equally feeding on all channels).
