    IntroductionStable isotope analysis has been widely used in the study of the trophic structure of marine micronekton in recent years.MethodsIn this study, the carbon and nitrogen stable isotope values of fish, cephalopod, shrimp and zooplankton species were measured from samples collected in the Northwest Pacific Ocean in March and September 2019 to construct a continuous trophic spectrum and to compare isotope niches among species. In addition, we compared the variation of isotopic niches of micronekton among different groups and among different species, respectively.ResultsSignificant differences of δ13C and δ15N values were detected among fish, cephalopod and shrimp groups with δ13C value ranges of −21.9‰ to −18.7‰, −21.3‰ to −17.7‰ and −20.4‰ to −19.5‰, respectively and the range of δ15N values was 7.0‰ to 12.4‰, 8.2‰ to 12.2‰ and 7.6‰ to 10.6‰, respectively. Using copepods as the baseline for estimating the average trophic level (TL) of micronekton, the TLs ranged from 2.67 to 4.80 and the average TLs for cephalopods, fishes and shrimp were 3.3 ± 0.3, 3.7 ± 0.6 and 4.0 ± 0.3, respectively. Myctophidae and Stomiidae occupied higher TLs. In addition, Oplophorus gracilirostris, Enoploteuthis chunii and Abralia similis had wide isotopic niches.DiscussionOur results show that Myctophidae, Stomiidae, Oplophorus gracilirostris, Enoploteuthis chunii and Abralia similis play important roles in maintaining the stability of the Kuroshio-Oyashio ecosystem in the Northwest Pacific Ocean.</p

    Considering economic, environmental, and social issues, the sustainability of the supply chain has drawn considerable attention due to societal and environmental changes within the supply chain network. The strategic study of the entire supply chain process and maximizing an organization’s competitive advantage depend heavily on supplier selection based on sustainable indicators. Selecting sustainable suppliers for the supply chain is challenging since it is a multi-criteria decision-making (MCDM) problem with significant uncertainty in the decision-making process. This study uses the VlseKriterijumska Optimizacija I Kompromisno Resenje (VIKOR) technique and single-valued neutrosophic sets (SVNS) to deal with the challenge of choosing a sustainable supplier with insufficient information. This method reduces the influence of personal experience and preference on the final evaluation results and the problem of excessive individual regret caused by factor correlation and improves the consistency of evaluation results. Finally, the method’s success and adaptability are demonstrated by sensitivity analysis and additional comparison analysis, and the benefits and drawbacks of the suggested framework are examined. Compared to other approaches, it can assist decision-makers in communicating fuzzy and uncertain information, offering a perspective and approach for MCDM in the face of such situations, and helping them select suppliers of high caliber and who practice sustainable business practices.</div
