Integrated fatty acid and stable isotope niches reveal trophic connections among sympatric large-bodied sharks

This study used a novel approach combining stable isotope data and condensed multivariate fatty acid data to define comparative niche space and overlap of six sympatric sharks from the southwest Indian Ocean: Galeocerdo cuvier, Sphyrna zygaena, S. lewini, Carcharias taurus, Carcharodon carcharias, and Carcharhinus obscurus.

本研究采用一种创新的方法，结合稳定同位素数据和浓缩的多变量脂肪酸数据，以界定西南印度洋六种共生鲨鱼（鲟鲨 Galeocerdo cuvier、锯鳐 Sphyrna zygaena、灰鳍鲨 S. lewini、虎鲨 Carcharias taurus、大白鲨 Carcharodon carcharias 和暗鳍鲨 Carcharhinus obscurus）的对比性生态位及其重叠区域。
