Comparison between global averaged trophic level (TL) and TL modeled from isotopic composition of the 30 consumers.

Global averaged TL are presented as mean ± SE and derived from fishbase and sealifebase databases, except for Cancer pagurus and Necora puber which are derived from seaaroundus database. Modeled TL are provided as mean and 95% credible intervals (CI) and calculated using tRophicPosition R package. ‘n’ = sample size. ‘Code’ = simplified taxa names used in figures. ‘Cluster’ = trophic group according to UPGMA clustering.
