Summary: Coastal wetlands play a crucial role in protecting communities from storm surge flooding and damages. This study assesses the impact of wetland loss and coastal development on storm surge damages in Galveston Bay, Texas, using a hydrodynamic model and land-use analysis. The findings highlight the importance of wetland conservation in reducing storm surge risks.

Summary: This study assessed the hydrology and water quality of the Wolf River and Jourdan River coastal watersheds using the SWAT model. The effectiveness of ponds, wetlands, riparian buffers, and their combination as best management practices (BMPs) were analyzed. The results showed that ponds and wetlands were effective in reducing total suspended solids (TSS) and mineral phosphorous (MinP).

Summary: The study found that methane emissions from reclamation-restored wetlands were significantly higher than those from natural wetlands, with SA wetlands having the highest emissions, primarily driven by SOC. Methane emissions in reclamation wetlands were mainly influenced by water levels and salinity, while the MPP of different soil layers was primarily affected by SOC and water levels.

Summary: The study focused on generating long-term fine-resolution precipitation datasets over the study region using a hybrid downscaling framework incorporating both dynamical and deep learning approaches. The results showed that the hybrid downscaling approach was more effective in generating precipitation datasets at a 6-km resolution compared to pure dynamical downscaling. The study demonstrated that the Convolutional Neural Network (CNN) could reproduce 6-km WRF simulated precipitation, emphasizing the importance of fine-resolution WRF modeling in enhancing downscaling performance. The hybrid downscaling framework was promising in preserving the physics of atmospheric dynamics in precipitation modeling and significantly reducing computational costs compared to pure dynamical downscaling.

Summary: Trash impairment of watersheds is a global environmental problem. Monitoring trash in streams and rivers is important to understand its effects on freshwater habitats and its transportation to marine environments. In Southern California, with its diverse land uses and a large population, the extent and types of trash were studied to develop mitigation strategies and evaluate management successes. The survey showed that coastal streams in Southern California had a high percentage of trash, with plastic being the most common type.

Summary: The tidal wetlands in Jiangsu Province are important blue carbon sinks, contributing significantly to biodiversity and ecosystem services. However, these wetlands have undergone drastic changes in scope, structure, and function due to anthropogenic activities and climatic changes. Using Landsat imagery and the CCDC algorithm, this study analyzed the spatiotemporal dynamics of these wetlands and identified the driving forces behind these changes. The results showed a significant decrease in tidal wetland area, primarily caused by human activities, and highlighted the importance of understanding the evolutionary patterns and drivers to enhance ecological services in the coastal zone.

Summary: The study reveals that microplastics are primarily concentrated in surface sediment and vegetated coastal sediments. Currently, carbon from microplastics contributes between 0.001% and 1.197% to sediment carbon pool at different depths. Despite the low contribution, microplastics have already had a hidden impact on coastal sediment carbon stock. These data help establish a baseline for the contributions of microplastics to total carbon storage in peri-urban coastal sediments.

Summary: The study revealed the significant carbon stocks in Mexican wetlands, with unprotected swamp forests and marshes containing substantial peat deposits, while grazed areas showed lower carbon storage effectiveness. Differences in carbon storage among wetland vegetation types in different regions highlight the need for region-specific government policies to protect coastal wetland carbon stocks.

Summary: This study found that the concentration of organochlorines in estuarine sediment is influenced by human activities in the watersheds, especially with higher risks of DDTs and PCBs. Furthermore, there is a significant correlation between non-agricultural GDP per capita and sedimentary concentrations of DDT and PCB, providing a tool for researchers to quantify the impact of human development in watersheds on environmental changes.

Summary: The study reveals that coastal wetlands have higher aboveground biomass but lower R/S compared to inland wetlands. Climate, soil, and hydrological factors have different impacts on R/S in wetlands, with a more significant effect on inland wetlands.

Summary: Depressional wetlands play a crucial role in wetland landscapes by storing and releasing water, providing habitat, and influencing carbon and nutrient cycling. The frequency and importance of surface connectivity in these wetlands is poorly understood, but our research shows that it is vital for the export of water-borne materials and numerous hydrologic and habitat services. Understanding and quantifying this surface connectivity is essential for evaluating the restoration of wetland landscape functions.

Summary: Microplastics are emerging non-degradable pollutants that impact humans and wildlife, especially aquatic species. Common shapes of microplastics observed in wetland ecosystems include fibers, fragments, filaments, foams, and microbeads. Research has identified high abundance of microplastics in wetlands and discussed advancements in extraction, characterization, and quantification techniques.

Summary: The US Department of Agriculture's Southeast Watershed Research Laboratory has conducted a long-term hydrologic research program on the Little River Experimental Watershed since 1967, providing valuable data on streamflow and rainfall relationships. Most regional watersheds shared similar hydrologic characteristics, except for some exceptions where changes in land use resulted in increased streamflow. The research conducted on this watershed has contributed significantly to the scientific understanding of flow and transport processes in stream systems.

Summary: While protected areas are successful in rescuing wetlands and shorebird habitats, plant invasions are extensive and undermine the formation of new native marshes. The global invasion of exotic species into protected areas highlights the profound consequences of bioinvasions on conservation.
