Summary: By analyzing the nitrogen and mercury isotopes of eels and pike, we found that pike has consistent mercury concentration and ecological traits, making it an effective bioindicator for mercury. Eels, on the other hand, better capture site-specific mercury sources based on their mercury concentration and feeding behavior.

Summary: The use of stable isotopes to understand plant physiological processes has become common in ecology. However, there is currently no standardized tool to calculate isotope-derived plant physiological indices. In response, we developed isocalcR, an R package that provides functions and reference data to simplify the use of stable isotope data in plant tissues.

Summary: This study investigates the carbon and nitrogen isotope fractionation characteristics during the degradation of atrazine in a constructed wetland. The observed isotope parameters are consistent with those observed in the cultivation of specific strains, indicating similarities in the biodegradation pathway and mechanism. However, variations in carbon and nitrogen isotope fractionation across different phases may lead to over- or underestimation of atrazine biodegradation extent. The accuracy of estimation improves when using the enrichment factor derived from batch cultivation of pore water. This study advances the application of compound-specific stable isotope analysis in tracking atrazine biodegradation in ecosystems, emphasizing the importance of carefully selecting and applying the enrichment factor for quantifying intrinsic biodegradation.

Summary: This study evaluated the contribution of plankton to the production of tambaqui juveniles in ponds at different stocking densities. The results showed that plankton accounted for 22.75% of the fish biomass. Density had an impact on turbidity and Secchi, while final biomass and average density were the only zootechnical indexes that differed.

Summary: In this study, multi-element compound-specific stable isotope analysis was used to evaluate the α-HCH and γ-HCH transformations catalyzed by LinA1 and LinA2 enzymes. The results showed slight differences in the isotopic fractionation patterns of different enantiomers, but both enzymes exhibited similar reaction mechanisms during γ-HCH transformation.

Summary: Barley exhibits great adaptability to salt tolerance in marginal environments due to its genetic diversity. Different tolerance mechanisms were observed in barley varieties, with tolerant ones showing higher carbon isotopes discrimination, CO2 assimilation rates, and proline concentration. Sensitive varieties, on the other hand, had increased lipid peroxidation.

Summary: Stable isotope mixing models (SIMMs) are used to characterize animal diets, relying on trophic discrimination factors (TDFs) to account for food assimilation. Traditional methods for calculating TDFs are impractical and may not reflect natural variability. This study presents TDFCAM, which estimates TDFs using high-precision diet estimates from nest cameras, and evaluates its performance in wild raptor nestlings.

Summary: This study aimed to investigate the effect of compound green tea on liver lipid metabolism in mice using metabolomics analysis. The results showed that compound green tea could regulate lipid metabolism and reduce body weight and blood lipid levels in mice. The metabolomic analysis also identified potential biomarkers and metabolic pathways related to fatty acid metabolism.

Summary: The study demonstrated the biotransformation of α-HCH in wheat using a hydroponic experimental setup. The major metabolite of α-HCH transformation in wheat was identified as 1,3,4,5,6-pentachlorocyclohexene, while no transformation was detected for β-HCH.

Summary: This study aimed to develop methods to determine the identity and trace the origin of propellants used in shotshells. Stable isotope ratio analyses were performed for propellant discrimination, successfully distinguishing propellants from different brands and countries using organic component and stable isotope analysis techniques. The results suggested that the samples contained different ingredients or raw materials from different sources, indicating the effectiveness of combined isotope analysis methods for origin tracing and identity determination.

Summary: The role of biochar in the removal of reductive pollutants from soil and water system has been extensively studied, but there is still a lack of understanding of its specific mechanisms in redox processes. This study reveals the mechanism of biochar in the transformation process of gamma-HCH under anoxic condition through compound-specific isotope analysis. The results show that biochar not only promotes the adsorption of gamma-HCH but also facilitates its transformation through the redox process.

Summary: This study analyzed the carbon stable isotopic composition of CO2 bubbles in sparkling sake to determine its authenticity. The results showed that the carbon source of the CO2 bubbles differed between sparkling sake manufactured using natural carbonation and those using exogenous carbonation. Carbon stable isotope analysis of CO2 bubbles can contribute to determining the authenticity of sparkling sake.

Summary: The study found that aerobic Gammaproteobacterial methanotrophs dominate in assimilating CH4 under anoxic conditions in Arctic lakes, and these methanotrophs have the capacity to generate intermediates such as methanol, formaldehyde, and formate from CH4 oxidation. This expands the knowledge of aerobic methanotroph metabolic processes and suggests potential coupling of CH4 oxidation to iron reduction in the Arctic lakes.

Summary: This study presents a submillennial-resolution record of lake water oxygen isotope composition from chironomid head capsules in Burial Lake, north-west Alaska. The record spans from the Last Glacial Maximum to the present, showing large shifts in lake delta O-18 values. These values are interpreted to reflect changes in lake hydrology, temperature, precipitation and atmospheric circulation patterns.

Summary: The study revealed the movement patterns of an Arctic woolly mammoth that lived 17,100 years ago, showing variations in mobility across a geographically extensive range during its approximately 28-year lifespan. Maintaining such level of mobility for megafaunal species like mammoth would have become increasingly challenging as the ice age ended and the environment changed at high latitudes.
