Summary: This study applied multiple reaction monitoring (MRM)-profiling to explore lipid classes in sea turtle plasma samples and found that most lipids have consistent relative ion intensities between species and seasons, with some species-specific differences. The research also identified a phylogenetic component in the variability of lipid profiles and seasonal differences in certain lipid classes. Overall, more lipids had higher relative ion intensity in the upwelling season compared to the non-upwelling season, with more variability observed in hawksbill turtles than green turtles.

Summary: Abundance estimates of green turtles and hawksbill turtles at foraging grounds in Bonaire were obtained using transect-count surveys, N-mixture models, and distance sampling during 2003-2022. The study found that the total abundance of green turtles remained stable from 2019 to 2022, while the total abundance of hawksbill turtles decreased between 2020 and 2021 and increased between 2021 and 2022. However, the overall estimates were similar to previous estimates and predictions. The methodology used in this study can be applied to monitor sea turtle populations in the Caribbean.

Summary: Head-starting programs for hawksbill sea turtles involve optimizing feeding frequency, and this study found that feeding the turtles twice daily with a long time interval (at 08.00 and 16.00 h) yielded the best growth performance and feed consumption. This feeding regimen also resulted in favorable digestive enzyme markers, nutrient utilization, and overall health parameters, making it an optimal choice for supporting head-starting programs for hawksbill sea turtles.

Summary: There is limited information about sea turtle nesting distribution and seasonality in the Saudi Arabian Red Sea, which could negatively impact local populations. A 2019 survey showed that nesting was found at all surveyed sites in the central Red Sea, although emergence counts were often low. Nesting in previously undocumented sites favored the seaward side of islands, unlike previously documented areas. The substrate composition varied, with most sites being composed of calcium carbonate except for Ras Baridi, which had dark quartz-rich sediment. Future developments should avoid key nesting areas and consider the seaward bias in marginal rookeries where possible.

Summary: Bycatch poses a major global threat to marine megafauna, and even small-scale fishing fleets that use gillnets are not exempt. This study provides the first evidence that hawksbill turtles feed on trapped fish in gillnets, suggesting that the presence of potential prey trapped in the nets may attract carnivorous sea turtles, increasing the likelihood of bycatch. This calls for technological and management solutions to address this overlooked depredating behavior.

Summary: In this study, plant-mediated zinc oxide nanoparticles were synthesized using Echinops macrochaetus and characterized. The low concentration of nanoparticles promoted growth and increased bioactive compound content, while the high concentration increased antioxidant enzyme activity. Accumulation of compounds was higher in the leaf compared to the shoot and root. Overall, this study revealed the stimulatory effect of phytomediated zinc oxide nanoparticles.

Summary: The study found that low-accumulating cabbage cultivars showed better root activity, cell integrity, root antioxidants, and shoot chlorophyll under arsenic stress. Arsenic was the main factor driving the structure of bacterial communities, and certain bacterial groups correlated positively with arsenic concentrations in high-accumulating cultivars. Low-accumulating cultivars had higher abundance of Patescibacteria in rhizosphere soils, which could immobilize toxic ions in the soil. The interactions between low-accumulating cabbage and bacterial communities under arsenic stress may play a role in plant arsenic uptake.

Summary: Whales accumulate high levels of environmental pollutants, such as polychlorinated biphenyls (PCBs) and their metabolites, which may lead to abnormal behavior and neuronal dysfunction. This study reprogrammed neurons from fibroblasts of mass stranded melon-headed whales and found that exposure to PCB metabolite 4'OH-CB72 caused apoptosis and altered gene expressions associated with neurodegenerative diseases. The noninvasive approach using fibroblast-derived neurons proved useful for assessing neurotoxicity in whales.

Summary: The Arctic region is facing contamination from long-range pollution and local human activities. Polycyclic Aromatic Hydrocarbons (PAHs) are used as environmental indicators for emission, transport, and deposition processes. Research conducted in the Arctic surface snow in Ny-Ålesund, Svalbard from October 2018 to May 2019 shows that long-range inputs of PAHs mainly occur in winter, while the most abundant analyte retene exhibits opposite seasonal trends.

Summary: In this study, a human physiologically based pharmacokinetic (PBPK) model of diethyl phthalate (DEP) was developed to assess its toxicity. The model considers the distribution and metabolism of DEP and its active metabolite monoethyl phthalate (MEP) in different tissue compartments. Sensitivity analysis and Bayesian Markov chain Monte Carlo (MCMC) simulations were performed to evaluate the uncertainty and variability of the model parameters. The results suggest that dermal absorption is an important route of exposure to DEP in the environment.

Summary: This study investigates the feasibility and mechanisms of a chemical-free nanobubble-based AOP for treating organic micropollutants in water. The results show that the oxygen nanobubble AOP has a significantly higher removal efficiency compared to air and nitrogen nanobubbles. The treatment performance is not affected by pH and the presence of ions. Higher initial concentrations of the micropollutant lead to slower treatment processes, but similar removal performance is achieved in the end. The presence of organic matter reduces the removal rate of the micropollutant. The results have practical feasibility for water and wastewater treatment.

Summary: This study investigates the impact of biochar on methylmercury (MeHg) accumulation in rice. The results show that biochar reduces MeHg levels in paddy soils by decreasing bioavailable Hg and microbial Hg methylation. Additionally, biochar decreases the uptake and translocation of MeHg in rice plants, resulting in a reduction of MeHg accumulation in rice grains.

It was found that increasing the application of thiencarbazone-methyl center dot isoxaflutole resulted in increased stress on soil bacterial community structure and diversity. Increasing soil pH was recognized as a key factor in improving the diversity and structure of soil microflora. Supplemental use of nitrapyrin or modified attapulgite can increase soil pH and improve bacterial diversity.
