Summary: This study investigates the metabolism patterns of lakes in Wisconsin, USA, and compares the differences in metabolic trends between oligotrophic and eutrophic lakes. The results show that oligotrophic lakes have diverse metabolism patterns, while eutrophic lakes exhibit consistent long-term trends of increased oxygen consumption over the last decade. The landscape setting is identified as the primary driver of long-term metabolic change.

Summary: Monitoring of surface waters in the boreal region over the last decades has shown that waters are becoming browner due to human impacts. Human land use since around 700 AD and industrial acid deposition in the 20th century have led to a decrease in lake-water TOC levels, resulting in unprecedentedly low levels. The study highlights the importance of considering past, long-term disturbances in understanding contemporary environmental changes.

Summary: By using remote sensing and satellite altimetry datasets, we reconstructed a time series of lake water storage changes in Xinjiang, China. The study found that temperature changes significantly affect lake water storage on plateaus, while precipitation is a key factor for lake storage changes in plain and transition zones. Additionally, extreme weather and human activities also play important roles.

Summary: The study reveals that rising temperatures at Crater Lake have led to earlier and stronger summer stratification, while the depth of stratification has decreased over the past 25 years. Climate change is driving similar trends in seasonal stratification in many large lakes.

Summary: Lake water levels are influenced by climate change and human activities, and extreme fluctuations can have negative impacts on lake ecosystems and related industries. The lack of long-term hydrological studies hinders the prediction of future water level rises. In this study, we analyzed nearly a century of data from Lake Yamanaka in Japan and found that increased precipitation significantly amplified the rise in water levels, sometimes leading to extreme precipitation events.

Summary: Water transfer from rivers to alkaline lakes has been proposed as a solution for lake water level drawdown and ecological degradation, but its effectiveness is often questioned due to the potential harm to lake ecology caused by a sudden pH decline in alkaline lakes. To understand the extent of this pH change, researchers developed a numerical model that couples a carbonate balance-based pH calculation method with a hydrodynamic model. The model accurately simulated the pH changes during water transfer and was applied to predict pH responses in Lake Chenghai. The results showed spatial and temporal variability in pH response, cumulative effects over time, and the impact of wind and inflow on the diffusion area of low-pH water. This study provides valuable insights for developing ecological water transfer strategies for alkaline lakes and similar water bodies.

Summary: Monitoring the water levels and volume changes of lakes and reservoirs is crucial for the protection and management of water resources. In this study, the integration of unmanned aerial vehicle (UAV) and Landsat data was used to investigate the long-term changes in Burdur Lake, providing accurate determination of water levels and volumetric changes.

Summary: Human disturbances have greatly changed the major ion chemistry in the Taihu watershed. Both the inflow rivers and Taihu lake have shown an increase in total dissolved solids and major ions in response to these disturbances. Factors such as algal biomass, land use change, and declining hydrological connectivity have played important roles in shaping the differences in water chemistry between the rivers and lake.

Summary: The study model shows that plant species richness in British semi-natural ecosystems has undergone significant changes over the past centuries, mainly influenced by the deposition of N-dep and S-dep, as well as soil pH and net primary productivity. Over the past two centuries, the average species loss reached 39%, but in recent years, there has been an increase in plant species richness due to reductions in S-dep and increases in soil pH, although there are also indications of recent slight recovery from the eutrophying effects of N-dep.

Summary: This study proposes an improved algorithm for monitoring inland water bodies using remote sensing images. The algorithm addresses the issue of missing data caused by clouds and other adverse conditions, and achieves high accuracy in recovering contaminated pixels. The algorithm improves the temporal coverage of the water area time series and provides valuable data for further analysis of lake dynamics.

Summary: Ciliate communities in lakes have experienced a decline in beta-diversity in recent times, especially in lowland lakes facing local human pressures. Changes in benthic ciliates are consistent with the increase in deep water anoxia. Sedimentary DNA analysis proves the potential of ciliates as new paleoindicators, offering insights into long-term changes in aquatic ecosystems.

Summary: Many European lakes have experienced reed die-back since the 1950s, possibly due to a single threat with high impact such as increased sulphate concentrations. A comprehensive study on 14 lakes in the Berlin area revealed a strong negative relationship between reed ratio and sulphate concentrations, as well as tree shading, and a strong positive relationship with brushwood fascines. Changes in water quality upstream should be considered in the management plans for downstream lakes.

Summary: This study focused on the spatiotemporal changes, ecological impacts, and influencing factors of water occurrence (WO) in Poyang Lake and Dongting Lake. The results showed a decreasing trend in WO in both lakes, with changes in landscape structure and increasing net primary production (NPP) and total nitrogen (TN). Natural factors such as upstream runoff and annual precipitation were found to influence WO changes.

Summary: This study focuses on the ungauged, semi-arid Gahai Lake in the Qaidam Basin, using satellite data to establish a hypsographic curve for lake area versus water level and estimate long-term water storage changes. The research reveals significant changes in the lake area, water level, and water storage since the beginning of the 21st century, largely attributed to climate change and human activities. The study provides an effective method for monitoring lake changes in ungauged basins by combining multiple models and satellite data.

Summary: This field study aimed to investigate the long-term fate of iron added to two urban lakes in Berlin, Germany, and evaluate the contributions of iron dosing to improve lake status. The study found that the addition of iron led to increased phosphorus retention in one lake while causing sulphur retention in the other due to varying sulphate reduction rates. Management interventions involving iron amendments to enhance phosphorus retention should consider the competing process of iron sulphide formation.
