Summary: This study found that excluding large carp can improve water clarity and vegetation in freshwater wetlands. After excluding large carp, water clarity improved and submerged aquatic vegetation cover and species richness increased.

Summary: By excluding invasive carp, we have successfully restored the historical conditions of the marsh, improving habitat quality for migrating ducks. The numbers of ducks and extent of submersed aquatic vegetation have rebounded to historical levels.

Summary: The study measured water and suspended sediment flows through patches of invasive SAV in three tidally forced, freshwater sites within the Sacramento-San Joaquin Delta. The results showed that sediment trapping efficiency was positive in most cases, and there was a strong negative trend in suspended sediment concentration over time, which could potentially reduce the resilience of marshes in the Delta and lower estuary to future sea-level rise.

Summary: Through experimental research on submerged macrophytes, it was found that the impact of macrophytes on aquatic ecosystems varies over time, including effects on dissolved organic matter concentration and phytoplankton biomass. Macrophytes increased the variance of ecosystem metabolic rates and dissolved organic carbon composition, while also affecting the variability of phytoplankton biomass.

Summary: This study compared three common methods of sampling submersed aquatic vegetation (SAV) in western Lake Erie. Results showed that the two field-based methods had the highest correspondence, while the correspondence between OBIA and hydroacoustics was the lowest. Determining the optimal method or combination of methods will depend on research goals, effort, and cost, but each method can provide reliable SAV information for resource management.

Summary: The experimental results demonstrate that geese have strong effects on plant cover and species diversity in restored urban wetlands. The presence of geese inhibits plant establishment and suppresses plant diversity, particularly of annual species. Therefore, protecting wetlands from goose disturbance is a crucial management activity that determines the composition and long-term persistence of vegetation. The reduction of non-migratory goose populations supports greater wetland plant diversity.

Summary: This paper reviews the utility of a long-term annual aerial monitoring program for submersed aquatic vegetation (SAV) in Chesapeake Bay and nearby coastal bays. It presents applications that highlight the program's importance in assessing anthropogenic impacts, gauging water quality, establishing restoration goals, and understanding the impact of commercial fishing practices on benthic habitats. New technologies enable more frequent and accurate aerial surveys at lower cost, supporting efforts to expand these applications to other areas.

Summary: Dissolved organic matter (DOM) is found in aquatic systems, and fluorescence techniques can be used to characterize aquatic fluorescent organic matter (AFOM). The production of AFOM is influenced by nutrient and dissolved organic carbon (DOC) concentrations, with different concentrations resulting in different proportions of autochthonous- or allochthonous-like AFOM. Additionally, the use of Peak T as a reliable surrogate for bacterial enumeration is uncertain.

Summary: This study found variation in species detection probabilities when using a modified garden rake for assessing submersed aquatic vegetation (SAV). The biomass-driven variation in detection probabilities may affect estimates of species occurrence frequency and habitat associations. Improved sampling protocols and modeling methods may lead to more accurate estimates of SAV occupancy.

Summary: Submersed aquatic vegetation plays a crucial role in sediment transport dynamics from the Susquehanna River to the Chesapeake Bay, with its effects varying under different flow conditions. The presence of vegetation can both facilitate sediment accumulation under high flows and enhance resuspension during wind-driven events. However, in significant discharge events, riverine dynamics dominate the system, with vegetation channeling the flow and enhancing net deposition.

Summary: Chemical pollution poses a major threat to global freshwater biodiversity, with the physico-chemical features of natural fresh waters playing a crucial role in influencing environmental risk and toxicity to aquatic wildlife. Understanding the variability of these features in natural fresh waters is essential for accurate environmental risk assessment and protection of organisms.

Summary: The study found that aquatic ecosystem metabolism in wetlands is greatly influenced by factors such as seasonal hydrology, water depth, vegetation density, temperature, and light. Gross primary productivity and ecosystem respiration are most affected by temperature and light, while net aquatic productivity is more sensitive to water temperature. High vegetation density can buffer seasonal variations in net aquatic productivity in wetlands.

Summary: The interaction between flooding, vegetation, and hydrogeochemical processes in riparian wetlands was studied using hydrochemical monitoring and DGT technology. Results showed that vegetation significantly influenced the hydrochemistry of the rhizosphere and shallow groundwater, with mineral dissolution and fermentation processes dominating the hydrochemical variability. Fe(II) release from wetland rhizosphere due to flooding may pose potential threats to surface water quality.

Summary: This review provides information on aquatic and semi-aquatic vegetation, including their ecology, morphology, and the environmental factors affecting their development. Aquatic plants play important roles in ecosystems and can be used as indicators of water pollution. Therefore, further study of aquatic and semi-aquatic plants is crucial.
