Summary: Deterministic models have become a widely accepted tool in investigations of lentic aquatic ecosystems. The current trends include the application of well-established models across broad ranges of time and spatial scales, the integration of various models, and the use of high-frequency sensors and remote sensing images for model initialization and calibration.

Summary: Phosphorus in lake sediments exists in diverse forms, often associated with metals, minerals, and organic matter. Understanding the composition and vulnerability of sediment phosphorus helps advance our knowledge of in-lake phosphorus retention and remobilization processes. In this study, phosphorus composition in surficial sediments was assessed across 236 lakes in Canada, revealing significant variations across different ecozones. Factors such as soil types in the watershed and the chemical composition of lake water and sediments were found to be critical in determining sediment phosphorus speciation.

Summary: Large and shallow freshwater lakes in the middle and lower Yangtze River (MLYR), China, are highly susceptible to eutrophication and cyanobacteria blooms due to extensive sediment-waterr interface and internal loading from sediment. The studies on these lakes have emphasized the importance of addressing in-lake physical and biogeochemical processes to control eutrophication.

Summary: As surface temperatures rise due to climate change, the effects on temperate lakes are expected to be more significant. However, the impact of changing snow and ice cover on lake communities is not well understood. This study investigated the underwater light climate and primary productivity patterns in six inland lakes in Minnesota, USA, under different water column properties. The results showed that snow cover not only affected the intensity but also the spectral signature of light in the lakes. The findings suggest that climate change-induced changes in snow and ice cover could impact phytoplankton primary productivity in sensitive aquatic ecosystems.

Summary: The Laurentian Great Lakes are complex systems with diverse biogeochemical processes, but our understanding of them is still incomplete. These lakes play a crucial role in supporting millions of people and driving trillions of dollars of economic activity, with biogeochemical changes impacting their functioning.

Summary: This study explored the effects of climatic variability on water quality in various water systems in the Netherlands, showing that water quality is impacted by global climate change, changes in Atlantic ocean circulation patterns, continental precipitation, river discharge fluctuations, and local climatic fluctuations. The fluctuations induced by climatic variability give a preview for the potential effects of climate change on water quality.

Summary: Nearshore habitats of deep lakes with high water quality are facing increased occurrences of filamentous algal blooms, posing potential threats to lake water quality and ecosystem. Coordinated efforts among the public, managers, and scientists are needed to study this phenomenon and take effective measures to protect lake ecosystems.

Summary: It has been found that huge amounts of synthetic chemicals and hydrocarbons released into inland waters and oceans have a significant impact on the carbon budget, especially the anthropogenic dissolved organic carbon (ADOC). The burial ability of ADOC by sediments in inland waters and coastal oceans is affected by ecological regime shifts, with differences between these two water systems. The burial ability of polycyclic aromatic hydrocarbons (PAHs), a type of hydrocarbon, decreased significantly over the years in Lake Qianhu and Lagoon Pinqing in China. The burial ability of PAHs was found to be correlated with different factors in each water system, such as total phosphorus concentration in Lagoon Pinqing and total nitrogen concentration in Lake Qianhu. Ecological regime shifts driven by nitrogen and phosphorus were responsible for the difference in burial ability between the two water systems. The study suggests that the burial ability of ADOC by sediments may be reduced if eutrophication leads to ecological regime shifts, which could undermine efforts to mitigate global warming.

Summary: The protection of biodiversity and ecosystem values in Antarctica is outlined in the Protocol on Environmental Protection to the Antarctic Treaty, which establishes Antarctic Specially Protected Areas (ASPAs) for areas with exceptional values. However, there is concern that existing ASPAs do not prioritize areas effectively for long-term conservation. This paper argues for the inclusion of inland waters in the ASPA framework to address their underrepresentation and proposes a structured approach for their selection, taking into account the limited knowledge of inland aquatic diversity and the need to consider catchment-scale processes.

Summary: For the past twenty years, lacustrine dissolved organic matter (DOM) has been a focus in various scientific disciplines due to its significance in carbon biogeochemistry and ecosystem functioning. The development of new satellites now allows for the evaluation of chromophoric dissolved organic matter (CDOM) in inland waters, which provides the opportunity to estimate DOM at appropriate spatiotemporal scales. This study evaluates the use of CDOM as a proxy for dissolved organic carbon (DOC) in seven Andean Patagonian lakes, and explores the relationship between CDOM absorption coefficients and DOC. The findings suggest that incorporating CDOM spectral shape information improves the estimation of DOC and has significant implications for environmental management, biogeochemical studies, and future remote sensing applications.

Summary: The particulate absorption coefficient is an important optical property describing the interaction of light with material in water, and its measurement in freshwater environments has presented challenges. This study proposes a method that successfully extracts unbiased pigments and non-algal absorption fractions in freshwater environments, providing valuable information for studying phytoplankton in lakes.

Summary: Small lakes can serve as environmental sensors for understanding regional hydrogeological conditions and elemental cycles. This study focused on nine lakes in the Carvel Pitted Delta in Alberta, Canada, and found that even though they were close together, these lakes exhibited significant differences in chemistry and nutrient characteristics. The variations in trophic states were attributed to differences in calcium concentrations, which are controlled by groundwater inputs. These findings highlight the importance of hydrogeological conditions and calcium inputs in regulating phosphorus availability and water quality in small lakes.

Summary: Severe eutrophication poses a threat to freshwater systems worldwide. The use of aquatic buffer zones can help reduce nutrient loading to downstream systems. However, the impact of these buffer zones on greenhouse gas emissions is not well understood. This study found that methane and nitrous oxide emissions were strongly correlated with nutrient loading, resulting in significant greenhouse gas emissions. The choice of plant species did not significantly affect total greenhouse gas emissions.

Summary: Impoundments in the midcontinent region of the United States provide important water resources but are often affected by eutrophication. The loading of nutrients from agriculture is a significant factor, with total phosphorus (TP) increasing in regional streams and reservoirs. Hydrology and reservoir placement strongly influence trophic state, while variation in TP throughout the year can mask the benefits of management practices. The expansion of industrialized animal production may lead to increased eutrophication if not regulated.
