Introduction Stable isotope analysis has been widely used in the study of trophic structure marine micronekton recent years. Methods In this study, carbon and nitrogen stable values fish, cephalopod, shrimp zooplankton species were measured from samples collected Northwest Pacific Ocean March September 2019 to construct a continuous spectrum compare niches among species. addition, we compared v...

Over the last few decades, the use of stable isotope ratios in ecological studies has increased greatly, most notably in the area of trophic ecology and food webs (Peterson and Fry 1987, Fry 2006). However, applications of stable isotopes in food web studies have been mostly qualitative to date, prompting the recent development of quantitative approaches to investigate different aspects of trop...
