Summary: This study investigates the impact of typhoons on lake ecosystems, specifically focusing on the loss of submerged macrophytes due to the abnormal water level fluctuations induced by a catastrophic typhoon. A circulation model coupled with dynamical models of fluid force and erosion was used to simulate the effects of the typhoon on vegetation, showing that fluid force rather than erosion was responsible for the massive loss of macrophytes. The study highlights the practicality of using this approach to evaluate environmental changes in lakes under different climate change scenarios.

Summary: Submerged macrophytes can increase water oxygen concentrations and promote diel oxygen fluctuations, playing a vital role in regulating N2O emissions in shallow eutrophic lakes. Study in Lake Wuliangsuhai found significant diurnal variations in dissolved oxygen concentrations in submerged macrophyte areas, with water oxygen levels being a major regulator of N2O flux.

Summary: The study investigated the epiphytic diatom community composition of three submerged macrophyte species in Chandos Lake, Canada and found significant differences among different species. These findings provide a basis for using paleolimnological methods to infer historical macrophyte community composition.

Summary: The optimal submerged macrophyte coverage for improving water quality in temperate shallow lakes is found to be 50%, which significantly reduces total nitrogen and total phosphorus concentrations, and improves water clarity.

Summary: This study investigates the existence of paleolakes in the isolated watersheds of the Mojave Desert, confirming their presence and the active nature of basin margins. The research shows that evidence of past high-lake stands is often buried but preserved by geomorphic processes, and suggests that the basin margin is where evidence of pluvial lakes should be sought. Some Holocene paleolakes in the Ivanpah basin seem to have persisted for decades to centuries.

Summary: The study found that the growth of Vallisneria natans can affect the total P and organic matter contents in lake sediments, increasing bioavailable iron and iron-bound P contents. The presence of V. natans also increased sediment bacterial diversity and reshaped bacterial community structure.

Summary: Submerged macrophytes promote water clarity in high-altitude Andean shallow lakes by reducing the cyanobacteria bloom and increasing zooplankton grazing. In a series of experiments in Yahuarcocha Lake, it was found that the presence of Egeria densa resulted in a strong reduction in cyanobacteria, while the small-sized fish Poecilia reticulata promoted cyanobacteria dominance. The combination of E. densa, fish, and zooplankton substantially reduced the algae, indicating the important role of submerged plants in improving water quality in high-elevation eutrophic ecosystems.

Summary: This study investigates the relationship between groundwater and lakes in Qaidam Basin using satellite images, meteorological data, and isotope analysis. It finds that groundwater, including glacial meltwater and water from other basins, significantly contributes to lake expansion. The study also suggests that earthquakes may be an important mechanism for lake expansion.

Summary: A new strategy was developed to improve nitrogen and COD removal in eutrophic water bodies by combining the use of submerged macrophytes (SMs) and artificial macrophytes (AMs). The results showed that the synergic application of SMs and biofilms on AMs enhanced SM growth and increased biofilm microbial biomass, leading to improved total nitrogen and chemical oxygen demand removal efficiencies.

Summary: The study shows that seasonal seismicity in central Japan is influenced by hydrological loads, especially variations in lake water storage, which dominate the seasonal stress changes. The research emphasizes the importance of understanding the impact of hydrological processes on seismic activity in the region.

Summary: This study investigated the successional dynamics, co-occurrence patterns, and community assembly processes of epiphytic biofilm bacterial communities on submerged plants. The results showed seasonal changes in EBC diversity and richness, with temperature being the most important driving factor. Co-occurrence network analysis revealed an increasing complexity of the EBC network, limited by temperature, pH, and transparency.

Summary: Macrophytes are crucial for shallow lake structure and ecological services, but are vulnerable to human activities and natural disturbances. The decline of macrophytes in East Taihu Lake is driven by ongoing eutrophication and hydrological changes, which result in reduced water transparency and light availability. The ratio of Secchi disk depth to water depth (SD/WD) is used as a critical indicator to demonstrate the driving forces and recovery potential of macrophyte decline. The proposed recovery potential model suggests that the current SD/WD is insufficient to support the growth of submerged and floating-leaved macrophytes, especially in the buffer zone. This study provides a basis for assessing macrophyte recovery potential and managing ecosystems in shallow lakes facing macrophyte loss.
