Summary: Sediment phosphorus release plays a crucial role in controlling eutrophication in Lake Chaohu, with higher release rates in the west region compared to the east. Long-term release is dominated by the remobilization of iron-bound phosphorus, while short-term release is mainly from legacy phosphorus in surface sediments.

Summary: Lake Wilcox, located in southern Ontario, has experienced water quality deterioration due to urbanization and increased salinization associated with expanding impervious land cover. Water column stratification, phosphorus speciation, and algal abundance were identified as the main factors contributing to the changes in water chemistry. It is suggested that stricter controls on de-icing salt application and runoff should be considered to manage eutrophication symptoms in lakes of cold climate regions.

Summary: The anthropogenic sources of phosphorus and chloride in lakes and rivers have been a long-standing concern in the Great Lakes Basin. This study focuses on the Sturgeon River - Lake Nipissing - French River basin and presents the first chloride and total phosphorus elemental budgets for Lake Nipissing. The findings indicate that despite a decrease in total phosphorus concentrations in major inflows, certain inflows, including those from agricultural areas, continue to exceed provincial objectives. Some inflows also show high average chloride concentrations attributed to road salt and agricultural activities. The study emphasizes the importance of community-based, spatially distributed water quality surveys for long-term ecosystem monitoring and planning.

Summary: In this study, the effect of wind-induced sediment resuspension on internal phosphorus in sediment treated by dredging and La-modified clay (LMC) based inactivation was investigated using a laboratory sediment resuspension simulation system (RSS). The results showed that dredged sediment had a better resistance to repeated wind disturbance compared to LMC-inactivated sediment. Both methods were effective in reducing phosphorus in different compartments of the lake, but their performances varied depending on the wind disturbance level. Inactivation was found to be a better method for controlling sediment internal phosphorus loading with repeated strong wind disturbances in eutrophic lakes.

Summary: This study uses material flow analysis and open data sources to map annual phosphorus flows across Ontario's economic sectors, identifying potential opportunities for phosphorus recovery and assessing their economic feasibility. The findings show that up to 86% of phosphorus imports for food production could be covered by recycling, with an average recovery cost of 49 CAD/kg of phosphorus. The cost is lower than the economic losses caused by phosphorus releases but higher than fossil-based phosphorus products, indicating the need for cooperative approaches for effective phosphorus recovery at a regional scale.

Summary: The estimation of groundwater-driven lacustrine dissolved inorganic phosphorus (DIP) loading is challenging due to uncertainties in simplifications used in empirical and numerical methods. A multidisciplinary approach can improve understanding and estimate accuracy, with field measurements and 3D flow modeling showing groundwater contributes 75-81% to lake budget. Different methods, such as lake segment approach and integrating water chemistry with 3D flow model, help to predict mass loading with higher accuracy and lower uncertainty.

Summary: This study conducted a five-year large-scale experiment in ten ponds to investigate the effects of nitrogen input on phosphorus dynamics. The results showed that sediment phosphorus release significantly increased when the nitrogen concentration exceeded a certain threshold. The release was most pronounced in summer and in sediments rich in organic matter. Several mechanisms were proposed to explain the stimulated phosphorus release, including N:P imbalance, alkaline phosphatase production, and disturbed sediment resuspension.

Summary: The study investigated the effects of different land-use types on soil P fractions and sorption-release characteristics in the eutrophic aquatic-terrestrial ecotone of Dianchi Lake. It found that different land use induced changes in soil P fractions and P stocks, with buffer zone soils showing higher P buffer capacity. However, despite the buffer capacity, there is still a high risk of soil P loss due to accumulation of available P in the soils.

Summary: This paper provides a detailed investigation of sediment internal P loading in Lake Taihu and its role in algal dominated zones (ADZs) and grass dominated zones (GDZs). The results show that ADZ sediments have higher levels of total P and mobile P fraction compared to GDZ sediments. The study also identifies ADZ as a hotspot for P, with high concentrations of DGT-measured P. Sediment microbial composition is found to be closely related to different P fractions in the sediment. The findings highlight the importance of considering the sediment composition and different management strategies for combating internal P loading in ADZ and GDZ.

Summary: This study examines the role of internal nitrogen (N) recycling in supporting Western Lake Erie cyanobacterial harmful algal blooms (cyanoHABs). The results show that the potential NH4+ uptake rates and regeneration vary spatially and seasonally, with the highest rates near the Maumee River inflow and during the peak bloom months. The internal N regeneration can supply NH4+ at a significant proportion of the bloom's demand and exceed the annual external N loading to the lake's western basin.

Summary: Mercury (Hg) sequestration by phytoplankton and subsequent consumption by herbivorous zooplankton can mediate the transfer of mercury to higher trophic levels. This study introduces two prey species to a predator-prey system to investigate the effects of different prey items on zooplankton assemblages. The results show that the nutritional quality of prey is a major driver of predator-prey relationships, with higher nutritional quality leading to prey-dominated food webs. The study also suggests that the homeostatic rigidity of the predator can help cope with toxic exposure.

Summary: Food web theory predicts that oligotrophication can lead to a decline in fisheries, but emerging evidence suggests that more complex trophic interactions can lead to ecosystem responses that deviate from theoretical predictions, especially in shallow littoral zones. Two end-to-end modelling strategies were used in this study to characterize potential food web structural shifts and overall ecosystem productivity in response to oligotrophication. The analysis suggests that reduction in phosphorus levels may not necessarily trigger a significant decline in fish biomass in the studied bay.

Summary: We investigated the relationship between biochemical and morphometric traits in sixteen fish species from the Canadian waters of the Laurentian Great Lakes. The study focused on the correlations between fish length, condition factor, lipid content, and polyunsaturated fatty acid (PUFA) composition in the dorsal muscle tissue. Linear relationships were found to be better representations of the correlations. Interspecific and among lakes differences accounted for most of the variability in fatty acid composition.

Summary: Phosphorus availability plays a crucial role in primary production and cyanobacterial blooms in lakes. Phospholipid substitution by sulfolipids has been established as an indicator of phosphorus stress in marine phytoplankton. This study shows that sulfatequinovosyldiacylglycerol (SQDG) to phosphatidylglycerol (PG) ratio can serve as a biomarker for phosphorus stress in freshwater phytoplankton communities, providing valuable insights into nutrient history and phosphorus scarcity.

Summary: Freshwater marsh restoration is a potential natural climate solution, but the preservation of organic carbon in marsh soils over policy-relevant timescales is uncertain. Comparative analysis of undrained reference marsh, passively restored marsh, and actively restored marshes in Canada showed that the reference site had the highest organic carbon accumulation and mass, while restored wetlands had variable organic carbon masses. Passive restoration generated high rates of organic carbon accumulation in low-lying sites with appropriate substrate and hydrology. Active restoration measures may promote organic carbon preservation, especially in fine-grained soil. The selection of restoration sites should consider substrate, topographic gradient, and hydrology for maximizing carbon sequestration.

Summary: Shallow littoral areas in lakes are important habitats for diverse invertebrate and vertebrate species, and their abundance, diversity, and nutritional quality are influenced by various environmental factors. Lake typology, habitat, water chemistry, and latitude all play a significant role in determining the taxon richness, abundance, and content of polyunsaturated fatty acids (PUFAs) in littoral macroinvertebrate communities. Understanding these relationships is crucial for maintaining the ecological balance and functioning of lakes.

Summary: The identification of gypsum on the surface of Mars presents a promising target for searching for signs of past microbial life, as gypsum is known to form in the presence of liquid water and has low porosity ideal for preserving organic material. This study in Qatar focused on organic matter preservation within gypsum, using DNA analysis and Raman spectroscopy to characterize extremophilic microorganisms and evaluate which organic molecules can be detected through translucent gypsum crystals. The results showed that organic material can be encapsulated in evaporitic gypsum and detected through Raman microscopy, providing valuable insights for detecting similar signals on Mars.

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.
