“…The higher δ 13 C values of tissues of heterotrophic bivalves studied herein agree with filter feeding on marine organic matter like phytoplankton, algae, and organic detritus (cf. del Rio‐Lavín et al., 2022). Interestingly, the studied mussels with their methanotrophic symbionts revealed diagnostic differences in carbon isotope composition among the different types of tissues (δ 13 C mantle < δ 13 C gill < δ 13 C foot ; Figure 3).…”

“…The lowest δ 15 N tissue value (−23.7‰) discovered to date was found for seep‐dwelling mussels from the Gulf of Mexico; 15 N depletion was ascribed to the uptake of ammonium with low δ 15 N values by the mussels or their symbionts (e.g., Becker et al., 2010). In addition to general uptake of organic matter‐bond nitrogen, the higher δ 15 N values of tissues of heterotrophic bivalves may in part be attributed to anthropogenic pollution (e.g., del Rio‐Lavín et al., 2022). Overall, the inter‐species variations of δ 15 N tissue values in chemosymbiotic bivalves are probably mostly controlled by the respective types of endosymbionts with variable degrees of fractionation during the uptake of dissolved inorganic nitrogen species (Rodrigues et al., 2013).…”

Aerobic methanotrophic bacteria are pivotal in the global carbon cycle by converting methane into biomass and inorganic carbon species. Light rare earth elements (light‐REE; La, Ce) are part of the metalloenzymes mediating the biochemical processes in methanotrophs. However, the partitioning of trace metals and REE in chemosymbiotic megafauna with methanotrophic endosymbionts remains largely unknown. Here we determine stable isotope compositions (δ13C, δ15N) of soft tissues (gill, mantle, foot) as well as trace metal and REE contents of soft tissues and shells of chemosymbiotic bivalves dwelling at methane seeps (Site F and Haima seeps) of the South China Sea. Isotopic compositions of soft tissues are found to reflect the mode of chemosymbiosis (i.e., methanotrophy vs. thiotrophy). Particularly gill tissues of bivalves with methanotrophic endosymbionts display marked light‐REE and trace metal enrichments, which is interpreted to reflect the enzymatic activity of endosymbionts. Additionally, correlations between light‐REE and copper (Cu), zinc (Zn), and molybdenum (Mo) contents in soft tissues of chemosymbiotic mussels are ascribed to the uptake of these elements by the methanotrophic symbionts. An observed higher trace metal content in the tissue of the semi‐infaunal and infaunal bivalves with thiotrophic endosymbionts is believed to reflect the uptake of metals associated with sulfide particles. This study documents diagnostic enrichment of trace metals and light‐REE in the soft tissues of bivalves with chemotrophic endosymbionts and provides new constraints for future identification of chemosymbiosis at ancient seeps.

“…It is well known that the isotopic composition of fish tissues is the result of several factors, such as the positions in food chains, the feed ingested throughout all life, kinetic fractionation due to metabolism, and geographical origin [17,28]. In particular, values of δ 13 C and δ 15 N in seafood are strongly influenced by the trophic position and feeding habits of each species since they vary according to the type and availability of prey and vegetations eaten by the animal, as well as the fractionation due to the metabolic processes that propagates along the aquatic food web [29][30][31]. Therefore, δ 13 C and δ 15 N measurements may be particularly useful to discriminate seafood according to the biological species, especially marine predators, which are at the top of the trophic chain.…”

In recent years, due to the globalization of food trade and certified agro-food products, the authenticity and traceability of food have received increasing attention. As a result, opportunities for fraudulent practices arise, highlighting the need to protect consumers from economic and health damages. In this regard, specific analytical techniques have been optimized and implemented to support the integrity of the food chain, such as those targeting different isotopes and their ratios. This review article explores the scientific progress of the last decade in the study of the isotopic identity card of food of animal origin, provides the reader with an overview of its application, and focuses on whether the combination of isotopes with other markers increases confidence and robustness in food authenticity testing. To this purpose, a total of 135 studies analyzing fish and seafood, meat, eggs, milk, and dairy products, and aiming to examine the relation between isotopic ratios and the geographical provenance, feeding regime, production method, and seasonality were reviewed. Current trends and major research achievements in the field were discussed and commented on in detail, pointing out advantages and drawbacks typically associated with this analytical approach and arguing future improvements and changes that need to be made to recognize it as a standard and validated method for fraud mitigation and safety control in the sector of food of animal origin.

“…Research endeavors have been conducted to ascertain the provenance and traceability of agricultural products using stable isotopes and elements combined with chemometrics: Cassiae Semen tea [21], Chinese garlic [18], Trachinotus ovatus and Pampus argenteus [22], avocado [9], durian [23], rice [24], apple juice concentrates [25], wine [26,27], and Mediterranean mussels [28]. Recently, Tanaka et al [29] used neodymium isotope ratio ( 143 Nd/ 144 Nd) to track the origin of Ruditapes philippinarum (clam) shells, and the results showed shell ƐNd is a powerful tool to discriminate the geographic location of clams.…”

Verifying the geographical origin of soybeans (Glycine max [Linn.] Merr.) is a major challenge as there is little available information regarding non-parametric statistical origin approaches for Chinese domestic and imported soybeans. Commercially procured soybean samples from China (n = 33) and soybeans imported from Brazil (n = 90), the United States of America (n = 6), and Argentina (n = 27) were collected to characterize different producing origins using stable isotopes (δ2H, δ18O, δ15N, δ13C, and δ34S), non-metallic element content (% N, % C, and % S), and 23 mineral elements. Chemometric techniques such as principal component analysis (PCA), linear discriminant analysis (LDA), and BP–artificial neural network (BP-ANN) were applied to classify each origin profile. The feasibility of stable isotopes and elemental analysis combined with chemometrics as a discrimination tool to determine the geographical origin of soybeans was evaluated, and origin traceability models were developed. A PCA model indicated that origin discriminant separation was possible between the four soybean origins. Soybean mineral element content was found to be more indicative of origin than stable isotopes or non-metallic element contents. A comparison of two chemometric discriminant models, LDA and BP-ANN, showed both achieved an overall accuracy of 100% for testing and training sets when using a combined isotope and elemental approach. Our findings elucidate the importance of a combined approach in developing a reliable origin labeling method for domestic and imported soybeans in China.
