Summary: Sea turtles in northeastern Brazil have been found to be affected by pollutants, specifically polycyclic aromatic hydrocarbons (PAHs). The study detected high levels of PAHs, such as phenanthrene, fluorene, and naphthalene, in the liver samples of green turtles. This research contributes to our understanding of the bioaccumulation of organic pollutants in sea turtles.

Summary: Chemical pollution poses a significant threat to cetaceans, and this study investigates the contamination levels of selected priority pollutants in stranded whales in the United Arab Emirates. PAHs were the predominant pollutants detected, while heavy metal concentrations were lower. Trauma and marine debris entanglement may have contributed to death in some cases.

Summary: The study examined the relationship between sea-surface temperature variability and the ecotoxicology of persistent organic pollutants (POPs) in eggs of two avian species with different trophic positions. It found that the Pacific Decadal Oscillation (PDO) predicted trophic position and levels of POPs in thick-billed murres but not in common murres. This suggests that facultative changes in foraging behavior, reflected in trophic position, can determine how POPs flow through and alter ecosystems under climate change.

Summary: Various synthetic organic compounds belonging to different chemical classes and possessing diverse physicochemical properties are frequently found in marine environments. These pollutants, such as microplastics, pharmaceuticals, pesticides, PCBs, and PAHs, have been detected in the global marine system, exerting direct and indirect effects on marine biota. Studies have explored the lethal and sub-lethal impacts of selected organic-synthetic stressors on different marine plant and animal species, as well as summarized the individual and combined effects observed or predicted after exposure to chemical mixtures of such contaminants. Future research needs are highlighted based on knowledge gaps in the literature.

Summary: Wildlife around cities are exposed to harmful environmental pollutants associated with human activities, and carnivores are particularly vulnerable to bioaccumulation of these pollutants. This study found that caracals in Cape Town are widely exposed to organochlorines, with higher exposure in human-transformed areas and wetlands. Biomagnification potential was higher in individuals feeding on higher trophic level and exotic prey. Exposure to these contaminants may have physiological effects and increase disease susceptibility. The urban fringes of Cape Town likely serve as a source of toxic chemicals for wildlife, requiring focused attention and action to protect these adaptable mesocarnivores.

Summary: This study quantified and compared legacy and alternative brominated flame retardants (BFRs) in the eggs of three gull species in a remote landfill in western Scotland. Despite high detection frequencies, the concentrations of hexabromocyclododecanes did not exceed those of polybrominated diphenyl ethers, indicating multiple exposure routes for gulls frequenting landfills through their diet, behavior, preening, dermal exposure, and likely inhalation.

Summary: In this study, yellow perch captured at four sites in the Lake St. Clair-Detroit River system were used to assess the sublethal effects of industrial pollution. The results indicated that higher sediment levels of industrial contaminants at the most downstream Detroit River site were associated with liver detoxification activity, reduced brain size, and disrupted food web in perch. Somatic growth and relative gut size were also affected by industrial pollution. Therefore, bioindicators of fish trophic ecology can be useful in assessing aquatic ecosystem health.

Summary: This article reviews the impact of anthropogenic pollutants on cell-cell interactions in biofilm-forming microorganisms. It shows that quorum sensing (QS) is an essential but underexplored mechanism affected by pollutants and serves as a key resistance mechanism for bacteria dealing with environmental contamination and promoting growth in unfavorable environments. The article highlights the value of considering QS as a critical mechanism for monitoring microbial responses in ecotoxicology and identifies QS circuits as promising targets for innovative biotechnological approaches in environmental science.

This study analyzed blood concentrations of various pollutants in a cohort of subjects from Cape Verde and found that 16.7% of the 360 toxic compounds were detected in at least one participant. The study also identified the most frequently detected substances and the factors influencing blood concentrations. This is the first biomonitoring study in Cape Verde and provides useful information for public health measures.

Summary: Inertial measurement units (IMUs) are essential tools in studying animal behavior, and hidden Markov models (HMMs) can effectively aid in identifying and classifying different behavioral patterns. Comparing accelerometer and magnetometer data, researchers found that models based solely on accelerometers were as accurate as those including magnetometer data, with the latter being particularly useful for studying certain behavior patterns.

Summary: With the increasing climate change, novel approaches are needed to monitor and manage ecosystem changes. This study explores the feasibility of using western gulls as indicator species for the state of marine ecosystems and investigates the interannual variability in gull foraging behavior. The results show that gull foraging behavior is related to upwelling conditions, prey abundances, and overlap with humpback whales. To better protect the threatened eastern Pacific humpback whale population, the deployment of gull tags with real-time data accessibility is needed.

Summary: Compared to other animal movements, prospecting by adult individuals for a future breeding site is commonly overlooked. By analysing movements of satellite- and GPS-tracked gull and tern populations, this study found that prospecting occurred in 85.7% of studied species, more commonly in populations with frequent inter-annual changes of breeding sites and among females. Further long-term tracking studies are needed to understand the factors affecting prospecting patterns and its consequences on fitness.

This study used GPS-tracking data from 23 seabird species to assess the importance of multi-year sampling for identifying important conservation sites. The results showed a high degree of spatial overlap among distribution patterns from different years, suggesting that tracking animals in multiple years may not be necessary. However, it is crucial to track enough individuals to provide a representative estimate of the population distribution during the sampling period.

By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
