The use of sulfur isotopes to study trophic ecology in marine ecosystems has increased in the past decade. Unlike other commonly used isotopes (e.g., carbon), sulfur can better discriminate benthic and pelagic productivity. However, how lipid extraction affects sulfur isotopic values has not been assessed, despite its frequent use to remove lipid effects on δ¹³C values.

脂质提取对不同海洋捕食者的同位素值（δ34S、δ13C 和 δ15N）具有组织依赖性影响

在过去十年中，使用硫同位素研究海洋生态系统中的营养生态学有所增加。与其他常用同位素（例如碳）不同，硫可以更好地区分底栖和远洋生产力。然而，尚未评估脂质提取如何影响硫同位素值，尽管其经常用于去除脂质对 δ ¹³ C 值的影响。
