为研究和比较不同深度热液喷口群落的营养结构，对伊豆-小笠原弧Myojin Knoll（1，220 - 1，360 m）和北马里亚纳弧尼科海山（380-550 m）的群落进行了优势种碳、氮稳定同位素比值分析。明神山藤壶的δ 15 N值较高，表明其来源于光合产物。同样，在尼科海山，一种多形多毛类，Gandulfus yunohana，一种黄蟹，Alvinocaaris sp.，而喜热无线鳎具有较高的δ 15 N值。这些动物也被建议消耗光合产物。明神穹丘的δ 13 C值范围比尼科海山的宽。这些数值范围之间的差异表明，两个喷口地点之间不同的化学环境影响了在每个地点发现的化能自养细菌的组成和分布，导致不同的区系。
To investigate and compare the trophic structures of hydrothermal vent communities at different depths, the carbon and nitrogen stable isotope ratios of dominant species were analyzed in the communities at Myojin Knoll (1,220–1,360 m) in the Izu-Ogasawara Arc and the Nikko Seamount (380–550 m) in the North Mariana Arc. At the Myojin knoll, a barnacle, Ashinkailepas seepiophila had high δ15N value, which suggested to be derived from photosynthetic products. Similarly, at Nikko Seamount, a polynoid polychaete, Gandulfus yunohana, a xanthid crab, Alvinocaaris sp., and Symphurus thermophilus had high δ15N values. These animals, too, are suggested to consume photosynthetic products. The range of δ13C values at Myojin Knoll was wider than that at Nikko Seamount. The difference between the ranges of these values suggest that different chemical environments between the two vent sites influence the components and distribution of chemoautotrophic bacteria found at each site, leading to different faunal
