Summary: This study assessed the response of aquatic macroinvertebrate communities to multiple anthropogenic stressors in a lowland river spanning from pristine sectors to densely populated urban areas. A bioassay procedure was developed to evaluate water and sediment quality, with macroinvertebrate organisms correlated with physicochemical parameters and pollutants. Significant changes in physicochemical parameters were found along a longitudinal gradient, with macroinvertebrates showing affinities for specific abiotic factors, highlighting their potential use as reliable ecological indicators.

Summary: Aquatic ecosystems contribute 50% of global productivity and play a crucial role in mitigating climate change. Factors such as water temperature, ocean acidification, nutrient availability, deoxygenation, and exposure to UV radiation interact to either enhance or decrease productivity. While ocean warming and deoxygenation may have opposite effects on mitochondrial respiration, they synergistically affect plankton migration and N-2-fixation of diazotrophs. Ocean acidification and elevated pCO(2) have controversial effects on marine primary producers, but they can worsen viral attacks on microalgae and reduce calcification of algal calcifiers when combined with UV radiation. Field observations over a long period of time are limited, but future studies are expected to explore the responses and mechanisms to multiple drivers in different regions.

Summary: The study evaluated the toxicity of PFOS and PFOA on four marine testing species and found the sensitivity ranking of M. galloprovincialis, S. purpuratus, P. lunula, and A. bahia. The results suggest that these species and endpoints are sensitive to PFAS, making them suitable for deriving toxicity data for other PFAS in marine ecosystems.

Summary: Several studies have shown that ingestion of microplastics has negative effects on aquatic organisms, including sediment-dwelling invertebrates. This study explores the interactive effects of exposure to polyethylene microplastics on the life history traits of midges, taking into account different temperatures, salinity levels, and food availability. The results reveal that microplastics' effects can be stronger at lower temperatures or severe food shortages, and that toxicity induced by microplastics is reduced under warmer temperature and salinity conditions.

Summary: The study revealed that the double constrained correspondence analysis (dc-CA) and CWM-RDA analysis methods can identify the relationships between benthic macroinvertebrate communities and environmental factors, with dc-CA being more effective than CWM-RDA. Traits such as aquatic stages, reproduction techniques, dispersal tactics, locomotion, and substrate relations were found to be associated with pollutants and water quality measurements. The dc-CA analysis showed that the set of environmental variables was more effective in explaining the community data than the trait set.

Summary: Ecological stoichiometry studies the balance and exchanges of chemical elements and energy between organisms and their environment. By integrating stoichiometric traits, researchers can better understand community and ecosystem processes, especially in response to changing nutrient levels in freshwater systems. Adding stoichiometric traits to available information on macroinvertebrate biological traits can expand trait approaches and improve the study of links between nutrient cycling and ecosystem functioning.

Summary: Human-driven environmental stressors pose an increasing threat to species survival and diversity in river systems worldwide. This study investigated the effects of persistent stressors, including land use and pollutants, on multiple communities in a human-dominated river in China over a 3-year period using environmental DNA (eDNA) data. The results showed that persistent stressors significantly reduced species diversity and stability, but increased species synchrony across multiple communities. The structures of interaction networks were also affected, leading to decreased modularity and cohesion. The decline in stability of multiple communities was mainly attributed to diversity-mediated pathways, such as increased species synchrony and changes in interaction networks.

This study focuses on the most important groups of parasites in organisms used in ecotoxicological studies and their effects on target species like crustaceans, molluscs, and fish. The combined effects of environmental stressors and parasites can range from additive to synergistic, highlighting the importance of considering parasite infections in ecotoxicological tests.

Summary: Urban estuaries are severely altered systems that undergo ecological crises and result in irreversible loss of biodiversity. This study investigates the variations of benthic macroinvertebrate communities and biotic indices in a highly urbanized fluvial-estuarine system and examines their responses to environmental alterations. Water parameters have a greater impact on the benthic community composition and diversity than sediment parameters, indicating that anthropogenic activities directly alter the ecological quality of urban fluvial sections.

Summary: Predicting the impacts of multiple stressors and understanding their interactions is crucial for ecosystem management. However, the lack of a general framework hinders such predictions. Using process-based models, this study investigates the generalization of interaction types across different biological levels in a two-stressor experiment on a seagrass model system. The findings reveal that interactions can be synergistic, additive, or antagonistic depending on various factors, including initial conditions, experiment duration, stressor dynamics, and consumer presence. These results shed light on the challenges of identifying consistent predictors of non-additive interactions in natural environments.

Summary: Developing population models for assessing risks to threatened or endangered plant species is challenging due to limited data on their life histories. This study developed a novel approach to identify data-rich nonlisted species as representatives for species listed under the ESA in population model development. The results showed that listed species are widely distributed across the plant phylogeny and do not share common vulnerability characteristics. Lifespan and age at maturity are important factors for distinguishing species clusters.

Summary: Untangling the relationship between network complexity and ecological stability under climate change, particularly extreme climatic events, is a challenging task. This study explores the effects of extreme heatwaves on the complexity of freshwater ecosystems and its correlation with stability components of the community. The findings suggest that reduction in network complexity leads to decreased functional and compositional resistance, while increased link-weighted network complexity improves functional and energy flux recovery and resilience but increases compositional instability.

This study assessed these effects in 19 planktonic food webs and found that warmer temperatures were associated with lower stability, while biodiversity had inconsistent effects. The responses of stability were linked to the contributions from different trophic groups and the synchrony of species within the food web.

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.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. 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.
