Supplemental Data of: Mouth gape determines the response of marine top predators to long-term fishery-induced changes in food web structure

Palate breadth of South American sea lions (Otaria flavescens), South American fur seals (Arctocephalus australis) and Franciscana dolphins (Pontoporia blainvillei) from Río de la Plata estuary. Stable isotope values (δ13C and δ15N) and standard length of the Franciscana dolphin (Pontoporia blainvillei) and potential prey species off Río de la Plata estuary. δ13C and δ15N: values not corrected for isotopic baseline shifts; δ13Ccor and δ15Ncor: values corrected for isotopic baseline shifts.

本数据集涵盖拉普拉塔河口（Río de la Plata estuary）的南美海狮（Otaria flavescens）、南美毛皮海狮（Arctocephalus australis）及拉普拉塔河豚（Pontoporia blainvillei）的腭宽数据；同时包含拉普拉塔河口外海域的拉普拉塔河豚及其潜在猎物物种的稳定同位素值（Stable isotope values，δ¹³C、δ¹⁵N）与标准体长数据。其中δ¹³C与δ¹⁵N为未校正同位素基线偏移的数值，δ¹³Ccor与δ¹⁵Ncor为经同位素基线偏移校正后的数值。
