A global meta‐analysis of marine predator nitrogen stable isotopes: Relationships between trophic structure and environmental conditions

Aim We examined potential environmental drivers of broad‐scale spatial patterns in the trophic structure of marine ecosystems as represented by nitrogen stable isotopes in globally distributed marine predators. Additionally, we assessed the effects of spatial scale on the predictive capabilities of environmental variables. Location Global oceans. Time period 2000 to 2015. Major taxa studied Tunas: Thunnus albacares , Thunnus obesus , Thunnus...
