Summary: In this paper, ecosystem metabolism data from tropical streams and rivers were reviewed to determine the similarities and differences with temperate streams. The study found that tropical streams exhibit similar metabolic constraints and drivers as temperate streams, with factors such as watershed area and land use influencing rates of gross primary productivity and ecosystem respiration. A structural equation model explained greater variation in ecosystem respiration than gross primary productivity, highlighting the key role of environmental factors in shaping metabolic rates in tropical streams.

Summary: The study found that the thermal responses of native oysters and invasive oysters to marine heat waves were context dependent, with native oysters showing changes in size and biomass while invasive oysters remained unaffected. The ability of native oysters to maintain their presence in the intertidal under sufficient food supply was highlighted, while the resilience of invasive oyster populations to climatic extremes may lead to competitive exclusion and further decline in native oyster populations. These findings are crucial for developing effective management plans to ensure the sustainability of natural oyster populations and maintaining key ecosystem functioning.

Summary: This study investigates the decomposition rates of coniferous leaf litter (CLL) in streams and rivers and analyzes the factors influencing CLL decomposition. The results show that CLL decomposition rates are slower compared to other global studies, and decomposition is faster in coarse mesh bags for evergreen and invasive conifers. Factors such as CLL traits, stream physicochemical characteristics, and experimental factors have a greater impact on decomposition rates than climatic and geographic factors. Nutritional quality, water temperature, and experimental duration are better predictors of CLL decomposition. Latitude, altitude, temperature, and precipitation also affect CLL breakdown rates. The findings suggest that the replacement of native forests with conifer plantations can significantly affect adjacent freshwater ecosystems, and climate warming may accelerate leaf litter decomposition, leading to potential food depletion for detritivores during hot summers.

Summary: This study examines the effects of floods on salinity by analyzing long-term observational records of daily streamflow and specific conductance in 259 monitoring sites across the United States. The results show that salinity changes during flood events exhibit large variability, with dilution being the prevailing mechanism. The analysis also reveals that the antecedent conditions of salinity prior to the flood are the most important factor in explaining intra-site variability.

Summary: Human activities and climate change have negative impacts on coldwater organisms in freshwater ecosystems by warming rivers and streams, increasing warm temperature events, and reducing thermal heterogeneity. It is crucial to adopt cohesive management approaches to protect cold-water refuges, considering physical, biological, and social factors. Current policies for protecting thermally sensitive species include designating cold-water habitats, restricting fishing during warm periods, and implementing temperature standards or guidelines. However, these policies lack coordination and Indigenous peoples' input. We propose managing cold-water refuges as distinct operational landscape units, integrating science and management to prioritize actions and implement adaptive practices.

Summary: Flowing waters play a crucial role in supporting global biodiversity, biogeochemical cycles, and human societies. However, the prevalence and significance of non-perennial rivers and streams are often overlooked, contributing to the degradation of water sources and livelihoods. By analyzing global data, it was found that a significant portion of the world's rivers experience at least one day of flow cessation each year, challenging traditional river concepts and highlighting the importance of considering intermittence in river management.

Summary: Non-perennial rivers and streams, which periodically cease flowing, make up more than half of global river and stream systems and are crucial to aquatic ecosystems. The authors argue for coordinated and collaborative efforts to understand their unique biogeochemical behavior, as shifts between wet and dry become more pronounced due to climate change. They discuss the challenges faced by the biogeochemistry of non-perennial rivers and streams and suggest actions that can be taken to address them.

Summary: Land use affects the biomass and composition of emergent aquatic insects, with higher biomass and abundance in agricultural sites. However, the composition of insect species is different between agricultural and forest sites, with shorter generation time insects being more common in agriculture. The timing and abundance of insect emergence vary between different orders in agriculture compared to forest, and this is influenced by pesticide toxicity and electrical conductivity.

Summary: Ecological recovery is often evaluated based on species diversity and composition, but recent studies suggest that considering biotic interaction networks can enhance long-term recovery success. In this study, we analyzed zooplankton community recovery in newly created lagoons using beta diversity approaches and inferred interaction networks. We found that differences in community structure between new and old lagoons increased over time, and the overall interaction network was more complex in new lagoons. Interestingly, the network structure in old lagoons became more complex after restoration.

Summary: Since the mid-20th century, Europe has seen a significant increase in non-indigenous crayfish species (NICS) due to their extensive use in fisheries, aquaculture, and pet trade. However, there is a lack of large-scale analysis on their occurrences and trends. In this study, using a freshwater macroinvertebrate database, we evaluated the information on NICS obtained from biomonitoring approaches and identified species-specific trends. We found no significant temporal trend for the abundance of any species at the European scale but identified predictors of abundances.

Summary: Pesticides can enter streams through runoff during rain events following agricultural application. Our study analyzed pesticide application and in-stream monitoring data from 101 agricultural catchments in Germany from April to July in 2018 and 2019. We found that toxicity to invertebrates and algae was highest in May/June, coinciding with the peak of insecticide and herbicide application. Future monitoring should focus on periods of highest pesticide applications.

Summary: This study presents a framework for evaluating spatiotemporal connectivity using two new measures: spatiotemporal connectivity (STcon) and spatiotemporal connectivity matrix (STconmat). The results show that spatiotemporal connectivity differs not only within but also among streams, and is related to macroinvertebrate community structure and composition. The framework can be applied to assess spatiotemporal patterns in different ecosystems by considering different time windows and/or network structures.

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.
