Stable isotope variation in the northern Gulf of Mexico constrains bottlenose dolphin (Tursiops truncatus) foraging ranges

Site-specific differences were found in consumer isotope values among ten sites examined in the northern Gulf of Mexico. Average δ 13 C values among sites ranged −21.7 to −15.7 ‰, δ 15 N ranged
