Meta-analysis review of fish trophic levels in marine protected areas based on stable isotope data

Stable isotopes (δ15N) have been used to determine trophic levels in marine food webs. This study assessed if Marine Protected Areas (MPAs) affect the trophic levels of fishes based on stable isotopes in the western Mediterranean. A total of 22 studies including 600 observations were found and the f...
