Summary: Balsamic vinegar of Modena (ABM) can be adulterated with added water. The official method for detecting adulteration is not suitable for ABM with high density. This study modified the official method by diluting the sample and correcting the data to eliminate the contribution of the diluent. The threshold limit of 618O, below which ABM can be considered adulterated, was identified.

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: The strontium isotope composition of human tissues is widely used in archaeological mobility studies, but there is often little consideration for the relative contributions of terrestrial and marine sources of strontium. By analyzing the dietary history and potential consumption of aquatic resources, future studies using strontium isotope analysis can avoid making erroneous conclusions about mobility patterns.

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 assesses the impact of the Koohrang III tunnel in Iran on the contiguous springs that provide water for drinking and agricultural activities. Prior to tunnel sealing, water seepage into the tunnel was estimated at 11.6 MCM/year, with the highest seepage occurring in karstic formations. After sealing, the total water seeping into the tunnel decreased to about 5.1 MCM/year. The tunnel excavation has caused a decrease in the flow of some springs.

Summary: Although many attempts have been made to improve the accuracy of trophic magnification factor (TMF) and biomagnification factor (BMF) for assessing pollutant bioaccumulation, this study suggests an improved BMF (BMF') for mercury bioaccumulation in freshwater fish. The results show that the values of BMF' are generally higher than TMF, indicating that it is a more reliable index for risk assessment. This ecological approach provides novel insights into the behavior and trophic transfer of pollutants like mercury.

Summary: Phosphorus is a crucial nutrient for marine organisms, and phosphorus input can affect primary productivity and trigger harmful algal blooms. The atmospheric transport of phosphorus to the ocean has been understudied. We measured oxygen isotopes in seawater samples from the East China Sea and identified the contribution of atmospheric phosphate using mixing models. Our findings reveal the significance of atmospheric phosphate input and its role in understanding harmful algal blooms and disaster prevention.

Summary: This study explores the utility of combining molecular and chemical techniques for dietary characterizations. By using DNA metabarcoding and stable isotope analysis, the researchers investigated the dietary niche of breeding Louisiana waterthrush. The results suggest that the waterthrush prefers pollution-intolerant, aquatic prey and the dietary characterizations from each approach were often uncorrelated.

Summary: This study evaluated chlorine isotope analysis of the organochlorine insecticide chlordecone hydrate using compound-specific isotope analysis (CSIA) and developed an evaluation scheme to correct for multiple isotope presence in polychlorinated compounds. The method was optimized for accurate chlorine isotope ratios, and the results showed satisfactory precision and long-term accuracy. This work provides potential applications for studying the fate of highly toxic and low reactive polychlorinated compounds in the environment using C-Cl CSIA approach.

Summary: The study found that Northern Goshawks in the Mediterranean mid-altitude mountain ranges in Catalonia prefer to nest in mature, well-preserved pine forests with little human disturbance. Therefore, forest management practices should aim to conserve these structural properties to protect Goshawk nest sites in the region. Future research should further investigate the role of this avian predator as a biodiversity indicator in Mediterranean forests.

Summary: Thirty years after its initial discovery, the marine cave stenopodid shrimp Odontozona addaia is reported for the second time, with new specimens found in marine caves in southern France. Morphological variability and DNA sequences suggest that the closest relatives of O. addaia are Odontozona meloi from the western Atlantic and Odontozona minoica from the eastern Mediterranean, although further research is needed to resolve their relationship.

Summary: The study found morphometric differences between male and female Bonelli's Eagle nestlings, particularly during the flight feathers' growing period, with body mass and claw length being the most discriminant variables. Different models for sexing Bonelli's Eagle nestlings can be applied based on geographic location, growth conditions, and the balance between accuracy and simplicity. Extrapolating sex discriminant functions to different subpopulations and growth conditions may be risky.

Summary: An unexpected conflict between vultures and livestock emerged in Europe over the last two decades. This study analyzed farmer complaints and found that the frequency of conflicts was influenced by factors such as livestock density, vulture abundance, proximity to landfill sites, and supplementary feeding stations. Farmers reported an increase in vulture attacks on livestock and expressed dissatisfaction with government policies and compensation.

Summary: Vultures are one of the most threatened bird groups globally. European vultures benefit from anthropogenic food sources like landfills, but EU directives to reduce organic waste in landfills may negatively impact some vulture species. A study in Central Catalonia, Spain, found that a reduction in organic waste in a landfill led to a decrease in vulture visitation probability, potentially causing permanent emigration. However, the overall abundance of vultures tended to increase over time due to positive regional population trends. This suggests that regional population processes are more important than local waste management measures for vultures. Conserving alternative feeding sources and implementing strategies to mitigate the negative effects of EU directives on scavenger populations are crucial.

Summary: In this study, a multistate Bayesian capture-mark-recapture approach was developed to address biases in demographic parameters caused by limited dispersal information. The method was applied to the data of a threatened population, the Bonelli's eagle in Catalonia, and substantial corrections of demographic estimates were observed. Our results also indicate that estimates are sensitive to the choice of the dispersal kernel.

Summary: This study examines the potential impact of landfill closures on the foraging patterns of Egyptian vultures. The results show significant differences in foraging strategies between non-breeders and breeders, with the removal of predictable resources affecting their foraging networks differently. In the absence of landfills, vultures are likely to increase their reliance on extensive livestock as a food source. Therefore, future environmental policies should consider expanding the areas where scavengers can access livestock carcasses to mitigate potential food shortages.
