Summary: Cypress domes, characterized by cypress trees and other subdominant species, are declining due to changes in land use and climate. This study found that the structure of cypress dome tree communities is correlated with hydroperiod and water depth, and wetland tree recruitment is affected by altered hydroperiods and water depths.

Summary: This study examines the pollen and plant macrofossil assemblages of a well-dated saltmarsh sediment core from southwest Newfoundland, Canada, to establish recent coastal vegetation and land use change. The wetland pollen and plant macrofossil records indicate a general acceleration in sea-level rise around AD 1700, while the upland pollen profiles suggest settlement events in the area around AD 1800 and AD 1850. Further analysis is needed to understand the representation of grass pollen and sedge species in saltmarsh sediments.

Summary: The Biloxi Marsh in Louisiana, located east of New Orleans, is a geologically stable wetland area benefiting from increased river sediment input, making it a prime candidate for restoration efforts. It has the potential to be restored to sustainability earlier and for a longer period compared to most other areas in the submerging Mississippi Delta. The lessons learned from restoration efforts in Biloxi Marsh can be applied to sustain valuable river deltas worldwide.

Summary: Aquifer storage and recovery (ASR) is an important component of the Comprehensive Everglades Restoration Plan. Using high permeability limestones in south Florida, the Kissimmee River ASR system successfully completed four cycles of recharge-storage-recovery, demonstrating the feasibility of ASR. However, improvements are needed in the pretreatment system to meet regulatory compliance.

Summary: The Atchafalaya River Basin, the largest forested wetland in the contiguous US, has experienced changes in hydrologic connectivity due to dredging and channel erosion. This study analyzed stage/discharge relationships, hydroperiods, discharge distribution, and channel cross-sections to find that much of the floodplain no longer receives sufficient discharge, resulting in stagnancy and hypoxia in the wetland. The confinement of discharge to a large channel also limits the system's ability to respond to sea-level rise and subsidence.

Summary: Maintaining environmental flows is essential for the management of river-lake-marsh systems, as these water bodies are closely interconnected in a basin. This special issue highlights recent advancements in understanding the mechanisms connecting hydrological and environmental/ecological processes, as well as the development of new methods and measures for e-flow management.

Summary: The relative importance of biological and abiotic filters in the assembly of co-occurring taxa in wetlands depends on the taxonomic group considered. Permanent water bodies and biological interactions such as competition directly influence functional dispersion of bird, invertebrate, and plant communities in wetlands.

Summary: This study evaluated the impacts of climate change on the water quantity and quality of the NLO watershed-Lake Okeechobee system using a spatially integrated modeling framework. The results suggest that the water quality of the lake is closely related to internal hydrodynamic processes, water level operations, and nutrient loads from upstream areas. Therefore, customized implementation plans and practices are necessary to improve the lake's water quality in the future.

Summary: The IBARI method of inferring river bathymetry from averaged images can increase the accuracy and precision of depth maps, while also improving the representation of channel morphology. This approach is suitable for data collected from helicopters and small unmanned aircraft systems.

Summary: Based on a subaqueous soil-landscape conceptual model developed previously, a subaqueous soil survey was conducted in the South River subestuary of Chesapeake Bay. The study area was sampled at 52 points to evaluate the predictive usefulness of the model. The model provided significant positive guidance for generating a useful soil map, but did not address the distribution of hypersulfidic materials.

Summary: The invasion of Spartina anglica significantly altered the characteristics of tidal salt marsh soil archaeal community, mainly in the surface layer, with indirect effects on deeper soil layers. Shifts in archaeal phyla such as Asgardaeota and Diapherotrites indicated a transformation from marine to terrestrial archaeal communities. Changes in dissolved organic carbon and salinity were the substantial regulating factors for the invasion impacts propagation to deeper soil layers.

Summary: This study used remote sensing images to monitor the dynamics of salt marshes in the largest wetland in the Yangtze River Delta. The results showed significant expansion and accretion of salt marshes, with adjacent mudflats remaining relatively unchanged. The seaward expansion of mudflats provided space for salt marsh growth and promoted their expansion.

Summary: This study evaluated the role of vegetation in regulating soil biogeochemistry in coastal salt marshes. The results showed that different wetland types had varying soil element concentrations and organic matter content, with organic matter content explaining the most variance. Furthermore, significant differences in element concentrations were found between Phragmites-dominated and Suaeda-dominated sites, even though their organic matter content did not differ significantly.
