Summary: The study shows that as lakes become more eutrophic, the probability of both nitrogen and phosphorus co-limitation significantly increases, while phosphorus-only limitation decreases. The concentration of phosphorus, rather than nitrogen, plays a main role in affecting the nitrogen to phosphorus ratio.

Summary: This paper provides a critical overview of the spatiotemporal variability in nutrient concentrations and the TN:TP mass ratio in the canal network of the Hydro system Danube-Tisza-Danube. The findings suggest that slow-flowing, lowland water courses in Serbia are exposed to non-point and point contamination sources, leading to eutrophication. These results are crucial for improving water quality and reducing nutrient runoff loads.

Summary: The study found that fish can increase the transfer efficiencies of certain essential substances from phytoplankton to zooplankton, while zebra mussels can decrease the transfer efficiencies of some fatty acids, likely due to competition with zooplankton for PUFA-rich food particles.

Summary: Our analysis revealed an increasing trend in phosphorus limitation across European forests from 1995-2017, with a negligible number of plots showing nitrogen limitation. The spatial variation in the rate of change in leaf N:P ratio was mainly associated with changes in N deposition and forest category, mean annual temperature, and soil C:N ratio. Overall, phosphorus is becoming more limiting compared to nitrogen, especially in broadleaved forests.

Summary: This study investigated the relationship between integrated landscape patterns and stream water quality in different seasons in ten Chinese subtropical catchments from 2010 to 2017. The study found that nitrogen and phosphorus levels in stream water varied significantly between the fallow season and the rice-growing season, and were influenced by different landscape configuration factors in each season. In the rainy season, stream water nitrogen and phosphorus levels were more likely to be affected by landscape composition, while in the dry fallow season, landscape configuration played a more significant role in determining nitrogen and phosphorus levels.

Summary: This study examines the impacts of climate change on streamflow and water quality in the subtropical Logan-Albert catchment in Australia. The results show that climate warming may lead to decreased streamflow and contaminant loads, with the largest decreases predicted during the dry season. This could result in reduced flushing and increased importance of point source loads in urbanizing catchments.

Summary: China has made efforts to improve water quality since 2000, resulting in a decrease in N concentrations in Lake Dianchi from a peak in 2007-2010 to 1.2 mg L-1 in 2018. Reducing external discharge is a priority for historical lake water quality improvement, while enhancing internal N removal is crucial for future lake ecosystem restoration.

Summary: This study provides a scientific reference for the investigation and treatment of nitrogen and phosphorus pollution in surface water of typical old industrial cities in China. The results showed that the pollution of nitrogen and phosphorus in the main rivers of Changchun City was serious, and their spatial distribution varied greatly. In terms of time, remarkable results have been achieved in the pollution control of ammonia and phosphorus through government river management efforts.

Summary: This study investigated the spatiotemporal variability of water quality in three transboundary East African Great Lakes. The results showed that nutrient pollution was severe in certain areas of Lake Victoria, while Lake Tanganyika and Lake Nyasa had relatively good water quality. The study highlights the importance of long-term monitoring and further research in the lakes and their basins.

Summary: This study investigates the storage and potential release of phosphorus (P) from the underlying roadway material in agricultural landscapes. The results show that the soil component of roadway materials is a significant P source and storage component. It is suggested that steps should be taken to divert roadway runoff into fields and improve road infrastructure to minimize P buildup. Future research should examine P loads in runoff from different farm typologies and roadway material types.

Summary: The results of the experiment showed that Cynodon dactylon 'Tifton 85' and Cortaderia selloana 'Pumila' have high absorption and purification capacities for nitrogen and phosphorus in eutrophic water, similar to Typha angustifolia. These three plants demonstrated rapid treatment of eutrophic water and significant purification effects.

Summary: Research analyzed the effects of sediment and plume fronts near the Changjiang River Estuary, finding that water mass shoreward of the sediment front had high nutrients but low chlorophyll-a concentration, while water mass between the sediment and plume fronts had high chlorophyll-a concentration. Coastal water mass beyond the plume front had low nutrients and chlorophyll-a due to reduced nutrient supply.

Summary: The three large marine ecosystems bordering China have been receiving excessive nitrogen and phosphorus inputs in the past decades, leading to the proliferation of harmful algal blooms. Future projections suggest that high nitrogen-phosphorus ratios will persist for decades, potentially worsening the situation.

Summary: This study explores the changes in water quality and ecosystem effects in Florida Bay, with a focus on the formation of picocyanobacterial blooms. The results show that drought leads to hyper-salinity conditions and seagrass die-off, while intense storms and hurricanes increase organic nutrient loads and cause pH decline, creating favorable conditions for the growth of picocyanobacteria.

Summary: Harmful dinoflagellate Planktonic Prorocentrum, particularly P. minimum, is on the rise globally. Researchers have developed a three-dimensional mechanistic model to predict the timing and location of P. minimum blooms in Chesapeake Bay, with temperature and nutrient conditions identified as the main factors influencing bloom development.

Summary: Research shows that the seasonal life strategy of Prorocentrum minimum in Chesapeake Bay relies on physical transport by estuarine circulation, with blooms occurring in spring successfully simulated by a hydrodynamic-biogeochemical model that tracked multiple years of life history. The study reveals that overwintering, spring transport, mid-bay bloom development, and downstream transport of decaying populations are key stages of P. minimum, with varying travel times due to differences in estuarine circulation strength throughout the year. May provides an optimal growth window for P. minimum as part of a seasonal succession from winter-spring diatoms to summer dinoflagellates.

Summary: The 2-year study aimed to understand the feeding preferences of eastern oysters in the eutrophic Rhode River in Maryland, USA. Results showed that oysters tended to selectively graze on various flagellates, diatoms, and dinoflagellates, while generally rejecting cyanobacteria, especially picocyanobacteria. This information can be useful for the management of dinoflagellate blooms and picocyanobacteria abundance to benefit oyster diets.
