Summary: The discharge of wastewaters harmed the recreational value of Lake Vesijarvi, but various measures were taken to mitigate this. The diversion of wastewaters reduced phosphorus concentration and intensive fish removal proved to be more successful in reducing cyanobacterial blooms. Later attempts at oxygenation and larger-scale intervention did not have the same positive impact and were eventually abandoned. The evaluation of fish removal intensity for maintaining the lake's current state is still ongoing.

Summary: This study implemented sustainable restoration treatments in Raczynskie Lake by using phosphorus inactivation with magnesium chloride and Phoslock(R) as well as biomanipulation to improve water quality. The results showed that water quality improved in the first year of treatment, but deteriorated slightly in the second year, highlighting the need for time and monitoring to achieve sustainable restoration.

Summary: This study provides ecology-based nutrient targets for five major ecoregions in Europe and reveals strong relationships between phosphorus and phytoplankton. However, the relationships between nutrient and biological communities are weak or non-significant in the very shallow lakes of the Eastern Continental region. Additionally, fish stocking negatively affects the ecological status of Eastern Continental lakes.

Summary: The efficiencies of restoring two lakes with different morphometries and trophic states using phosphorus inactivation method with sequential application of iron and aluminum compounds were compared. The results showed that the dimictic, eutrophic Lake Klasztorne Duze had better phosphate removal efficiency from surface water layers. However, the dosing of compounds did not lead to complete precipitation of phosphates from the bottom water layers of either lake. Inhibition of the internal loading process was observed in both lakes. The use of two types of compounds can reduce restoration costs and ensure higher ecological safety with the dosing of iron salts in the coastal areas of the lakes.

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 analyzed the effectiveness and longevity of aluminum treatments in six Swedish lakes over the past 25 years, revealing significant improvements in water quality parameters post-treatment and a correlation between treatment longevity and factors such as lake type, aluminum dose, and watershed area. Additionally, a higher binding efficiency between aluminum and phosphorus was positively related to treatment longevity, a relationship not previously demonstrated.

Summary: The study evaluated the toxic effects of novel phosphorus (P) adsorbents (magnetic particles, MPs) on phytoplankton community in a hypertrophic Mediterranean lake. Results showed that MPs did not cause any toxic effects on the phytoplankton community of the lake, encouraging the use of MPs in a future whole-lake restoration strategy.

Summary: Given the increasing eutrophication of water bodies in Africa, this study aimed to understand the short-term response of phytoplankton communities to nutrient addition and the presence of fish. The results showed that the addition of nitrogen and phosphorus stimulated phytoplankton growth, but fish presence led to a decrease in biomass. These findings provide valuable insights for strategies to control cyanobacterial blooms.

Summary: The study found that under high-greenhouse-gas-emission scenario, lake stratification will start 22.0 +/- 7.0 days earlier and end 11.3 +/- 4.7 days later by the end of this century. This 33.3 +/- 11.7 day prolongation in stratification will likely accelerate lake deoxygenation and impact nutrient mineralization and phosphorus release.

Summary: Integrated biomanipulation, combining traditional and non-traditional methods, was successfully used in Longhu Lake to control cyanobacterial blooms and improve water quality for 20 years. Compared to single-bomanipulation scenarios, integrated biomanipulation showed better ecosystem stability, higher energy flow transfer efficiency, and improved ascendency.

Summary: This study found that vegetation restoration significantly increased the sediment's capacity to tolerate phosphorus pollution in river-lake ecotones. The content of total phosphorus in sediments was highest in summer and autumn, while lower in spring and winter. Vegetation restoration affected the distribution and circulation of phosphorus in river and lake ecosystems, enhancing the ecological function of the river-lake ecotone.

Summary: The variability of physicochemical parameters in small waterbodies impacts aquatic macrophytes, which are crucial for the classification of reservoirs. However, nutrient-rich small waterbodies in rural areas may present challenges for accurate assessment. Only a canonical analysis considering environmental variables and plant species allows satisfactory results to be obtained.

Summary: Land use significantly affects the function of waterbodies. The study found that the influence of land use, especially agricultural land, is greater within the zone 100 meters away from the shoreline of the waterbodies. Therefore, it is recommended to move the border of intensive farming areas beyond the 100-meter buffer zone or reduce the intensity of agriculture and introduce diversified and perennial vegetation to create effective biogeochemical barriers.

Summary: This study examines the functioning of a lake-river system subjected to restoration treatments by analyzing the water quality of two tributaries, a shallow, restored lake, and its outflow. The results show that the nutrient concentrations at the inflows decreased over the years due to improved water and sewage management in the catchment. The quality of water at the outflow improved due to changes in the applied restoration methods and the better quality of water at the tributaries. However, during limited restoration, the outflow still contained high levels of chlorophyll a and suspended solids.

Summary: This study aimed to investigate the effects of water level and habitat heterogeneity on gastropod fauna in the littoral zone, and the differentiation of functional feeding guilds (FFG) of gastropods. The results showed that gastropod abundance was higher during low water level (LWL) in the waterbodies with macrophyte stands, while it was higher during high water level (HWL) in the waterbodies without macrophytes. Microhabitat diversity and submerged macrophytes were found to play an important role in providing food sources and safe shelter for gastropods.

Summary: The successful management of lake ecosystems used for recreation depends on identifying nutrient sources and implementing appropriate measures. This study analyzed external and internal nutrient loading in the hypereutrophic Raczynskie Lake, finding distinct seasonal variability in both sources. To improve water quality, it is essential to divert stormwater runoff, reduce nutrient content in tributaries, and implement restoration treatments for phosphorus inactivation and reduction.

Summary: Phenology monitoring is important for understanding forest functioning and climate impacts. This research compares the phenological behavior of European beech forests using Tree-Talker (TT+) and Sentinel 2 satellite data. The study finds differences in the information derived by the two sensor types, particularly in terms of season length, phenology changepoints, and leaf period variability. TT+ with its higher temporal resolution demonstrates precision in capturing the phenological changepoints, especially when satellite image availability is limited.
