Large-scale patterns of green turtle trophic ecology in the eastern Pacific Ocean

Trophic position and niche width are fundamental components of a species’ ecology, reflecting resource use, and influencing key demographic parameters such as somatic growth, maturation, and survival. The present data file contains results of stable isotope analysis (stable-carbon, δ13C; stable-nitrogen, δ15N values) that was conducted on bulk skin tissue of 718 green sea turtles (Chelonia mydas) distributed among 16 foraging areas in the eastern Pacific from the US to Chile, a range spanning ~10,000 km. These study sites were distributed across a latitudinal range from 33.736 °N to 23.098°S in the Eastern Pacific (Site Code): Long Beach, USA (LB); San Diego Bay, USA (SDB); north Gulf of Ulloa, Mexico (NGU); Magdalena Bay, Mexico (BMA); Los Angeles Bay, Mexico (BLA); Infiernillo Channel, Mexico (CIN); Navachiste Bay, Mexico (NAV); Dulce Gulf, Costa Rica (DUL); Cocos Island, Costa Rica (COC); Gorgona Island, Colombia (GOR); Punta Espinosa, Galapagos Islands, Ecuador (IGP); Bahia Elizabet...
