Summary: To meet the demand of a growing population, agriculture intensifies and leads to increased use of fertilizers and pesticides, which can disrupt water quality and impact aquatic life. This study evaluates the efficiency of an agricultural retention pond in reducing the supply of nutrients, pesticides, and suspended solids to a tributary of Lake St. Pierre. The study finds that the removal of pesticides varied, while the removal of suspended solids, phosphorus, and nitrogen was relatively high. However, the retention pond was not consistently effective in removing toxicity.

Summary: Urban retention ponds are a common stormwater control measure in coastal areas, but can also be a source of pollutants. Research showed that the treatment efficiency of retention ponds improved during warmer months, likely due to increased biological activities. Modeling with SWMM can help assess performance beyond one-year monitoring studies, suggesting additional research to better understand biogeochemical processes within ponds.

Summary: Recovering nutrients from organic materials and reducing artificial fertilizer inputs can be costly and involve logistics. Direct application of organic materials to agricultural land can contribute to pollution. Assessing the cost of increased recycling requires a spatially explicit approach. A multi-objective model was developed to estimate the trade-offs between costs of nutrient recovery and improvements in nutrient distribution. Results showed limited potential for replacing nitrogen and phosphorus fertilizers through nutrient recovery. Increasing manure processing for nutrient recovery led to a redistribution of nutrients and trace metals. Our model provides a methodology for assessing the trade-offs between increased recycling and spatial effects for sustainable agriculture.

Summary: The conversion of grassland into cropland led to significant decreases in soil organic carbon and total nitrogen contents, while total phosphorus content increased in deeper soil layers. Abandonment of cropland resulted in higher levels of soil organic carbon and total nitrogen compared to cropland, although not reaching levels of native grassland. Grassland had the highest nutrient contents and ratios, followed by abandoned land and then cropland.

Summary: This study found that climate change and food web structure can impact the significant clear-water phase in lakes, with effects varying among different metrics. Higher water temperature leads to earlier start and peak dates of the clear-water phase, while the proportion of D. pulicaria affects all clear-water phase metrics, and high Bythotrephes density delays the start date of the clear-water phase.

Summary: Multiple studies have shown widespread browning of Northern Hemisphere lakes. An examination of Northeastern U.S. lakes found that the majority of lakes have experienced an increase in both DOC and color, with variable trends and no strong correlation between them, suggesting other factors beyond terrestrial carbon loading may be at play. Browning may be more prominent in regions where climate and atmospheric deposition are dominant drivers.

Summary: Current research on freshwater resources globally indicates a deteriorating water quality, with studies often focusing on large water bodies and using biased sampling data. In the United States, satellite remote sensing data reveals an increasing trend in lake water clarity since 1984, particularly in densely populated areas and smaller water bodies pre-2000. This suggests that extensive pollution control measures in the U.S. have been effective in improving water quality.

Summary: This study investigated the concentrations and fluxes of N2O in four watersheds on the East Qinghai-Tibet Plateau between 2016 and 2018. The findings show that permafrost rivers in this region release relatively low levels of N2O, despite the high N2O emissions from thawing permafrost soils. This is attributed to the uptake of dissolved inorganic N by terrestrial plants, unfavorable conditions for N2O generation through denitrification, and a low N2O yield due to a small ratio of nitrite reductase to nitrous oxide reductase in these rivers. The study estimates the fluvial N2O emissions from permafrost landscapes on the entire Qinghai-Tibet Plateau to be relatively small, but suggests that these permafrost-affected rivers may become significant sources of N2O in the future, contributing to the permafrost non-carbon feedback that intensifies warming.

Summary: Millions of lakes worldwide experience the formation of lake ice during winter, impacting the transfer of energy, redox processes, and ecological community structure. However, there is a lack of understanding about how these effects vary in response to different winter climate conditions. Global climate change is driving ice-covered lakes towards warmer temperatures and reduced ice cover, emphasizing the need to understand the role of winter in the annual aquatic cycle.

Summary: Our changing climate is affecting freshwater ecosystems, particularly in winter. Lakes, wetlands, and rivers at high latitudes are experiencing shorter periods of ice cover, while lower latitudes systems are seeing open water conditions throughout the winter. These changes impact gas exchange, metabolism, and other processes in the water. There is a need for further research to understand the effects of changing winters on freshwater systems.

Summary: Streams and rivers are major sources of greenhouse gas emissions. While our understanding of individual gas flux drivers has improved, the lack of consistently collected samples hinders our ability to analyze the interrelationship between gas concentrations and their drivers. This study analyzed a dataset collected by the National Ecological Observatory Network, providing insights into the physical and biogeochemical drivers of greenhouse gas production in 27 streams and rivers across the United States. The results show that physical drivers such as temperature, stream slope, dissolved oxygen, and total nitrogen concentration strongly influence the concentrations of CO2 and CH4, while N2O is exclusively correlated with total nitrogen concentration.

Summary: Despite their small size, fluvial ecosystems play a significant role in carbon processing and methane emissions. However, progress in understanding and estimating methane concentrations and fluxes in streams and rivers has been slow due to variability and limited data availability. In order to address these challenges, the Global River Methane Database (GriMeDB) provides a comprehensive resource of methane concentrations and fluxes, along with physical and chemical data, to examine environmental drivers and estimate fluvial contributions to methane emissions.
