Summary: This study investigates the impacts of tidal and wind changes on seed arrival and retention in salt marshes, essential for marsh regeneration. Results show that spring tides are more effective in seed dispersal than neap tides, and storm-induced extreme water levels deliver higher amounts of viable seeds. Seed retention decreases with increasing onshore wind speed, with storm-induced wave disturbance wiping out seeds on wind-exposed marshes.

Summary: This study investigates the effects of plant invasions on soil microbial communities and functions in salt marshes. It finds that microbial diversity is positively correlated with the duration of invasion, and both bacterial and fungal communities show consistent changes with invasion. The metabolic potential of soil microbes decreases in response to invasion, leading to carbon accumulation in invaded salt marshes. Bacteria and fungi have distinct contributions to microbial community assembly along the invasion gradient.

Summary: Annual mapping of the Yellow River Delta wetland from 2008 to 2019 using time-series Landsat images revealed a significant expansion of Spartina alterniflora, encroaching on other vegetation types. The study found that the number of valid observations affects spatial and temporal classification accuracies, with harmonic regression features playing a crucial role in improving overall accuracies. Temporal distribution of observations was identified as more important than the quantity of observations for harmonic-based classification of coastal wetlands like the YRD.

Summary: Coastal wetland ecosystems, such as saltmarshes, are effective in sequestering carbon to mitigate climate change. The effects of vegetation dynamics, specifically the invasive Spartina alterniflora and native Phragmites australis communities, on soil organic carbon (SOC) and its fractions were examined. The study found that plant ecophysiological traits influence the spatial distribution of SOC, and the different vegetation communities have different impacts on its accumulation and decomposition. These findings provide insights into the impacts of long-term species invasion on SOC in coastal wetlands under global changes.

Summary: Salt marshes are important ecosystems that provide essential ecological services, but they have been lost globally due to human activities and climate change. The interactions between tidal water and groundwater in salt marshes affect plant growth and biogeochemical exchange with coastal water. However, there are still significant knowledge gaps regarding the hydrological and ecological links in salt marshes and the challenges they face.

Summary: This study reveals that the mussel, Geukensia demissa, has a significant effect on saltmarsh accretion in the southeastern US, with deposition being 2.8-10.7 times higher on mussel aggregations compared to other marsh locations. The study also predicts that mussels drive substantial changes to the magnitude and spatial patterning of accretion at marsh domain scales. Moreover, a manipulative experiment involving over 200,000 mussels shows that the faunal engineer has a much larger impact on relative marsh accretion rates than expected. Therefore, there is a critical need for empirical, experimental, and modeling work to understand the importance of faunal engineers in modifying the persistence of coastal ecosystems globally.

Summary: Globally, mangrove range limits are expanding, potentially affecting adjacent coastal ecosystems. This study in the Apalachicola Bay region of Florida found that soil organic carbon density in mangroves is not significantly influenced by dominant plant taxa, but rather by site-specific environmental attributes. The findings also indicate that shifts in plant taxa have occurred at all study sites. Overall, mangrove soil organic carbon concentrations are equal to or lower than those of neighboring saltmarsh habitats.

Summary: This study explored the importance of plant species and different habitat conditions to synchrony in plant productivity across coastal marsh habitats in Georgia, USA. Synchrony was highest within a plant species and within a marsh zone, and decreased across species with increasing distance and elevational differences. Abiotic conditions, such as water column temperature and salinity, also showed high synchrony among sites, pointing to the Moran effect as a likely explanation for the findings.

Summary: Spartina alterniflora, China's most common invasive species, poses challenges to native plant communities and coastal environments. Current spatial analyses are insufficient, so we used multisource high-resolution imagery to monitor the invasion and dieback process of S. alterniflora. Our findings show that the area of S. alterniflora decreased over time, but it continues to grow along the seaward side. The dieback of S. alterniflora is related to certain factors such as the number of tidal creeks and the length of artificial ditches. These findings provide a scientific basis for the ecological control and management of S. alterniflora, promoting evidence-based strategies for coastal wetland protection.

Summary: The study found that woody encroachment of mangroves into coastal wetlands can lead to a decrease in plant species richness and changes in animal assemblages, with certain species being more common in areas without mangroves. Results were consistent with a previous manipulative experiment, indicating mangroves have significant impacts on associated plant and animal communities as woody encroachment continues and mangrove cover increases.

Summary: As climate warms, the strength of microbial thermal acclimation and its effects on soil carbon feedback may be influenced by multiple environmental factors, including nitrogen concentration and soil acidity. This study found that under warming conditions, higher nitrogen enrichment reduced the mass-specific respiration rates in alpine permafrost soils. The strength of thermal acclimation was found to increase as nitrogen enrichment increased, but the pathways by which nitrogen affects acclimation can vary.

Summary: A new electron shuttling pathway was discovered in Shewanella oneidensis MR-1 using the lipophilic electron mediator resazurin. This pathway is independent of the Mtr pathway and relies on the involvement of FccA, CctA, and CymA. The findings provide new insights into the role of exogenous electron mediators in electron shuttling in natural and engineered biogeochemical systems.

Summary: Coastal wetlands are vulnerable to sea-level rise, extreme climate, and human activities, especially in large river deltas. This study quantified the changes in area and patch number of coastal wetlands in China's four major river deltas, and assessed the effects of driving factors. It was found that the Liaohe River Delta and Yellow River Delta experienced substantial losses, while the Yangtze River Delta showed recent recoveries. The Pearl River Delta had a relatively stable area trend but an increasing patch number trend. Protected areas were effective in halting the decreasing trends in coastal wetland areas, but were counteracted by invasive plant invasions.

Summary: This study proposes a breathable encapsulated LM foam (BELMF)-based soft stress sensor by using two polydimethylsiloxane foam layers to encapsulate the liquid metal and designing a three-dimensional electrode for electric connection without compromising breathability. When stress is applied, the LM foam collapses and forms new conductive paths, reducing the resistance of the sensor. The BELMF-based sensor has a sensitivity of 1.4 Pa-1 and potential applications in monitoring human motion.

Summary: Electrochemical advanced oxidation processes (EAOPs) are effective in removing organic waste-water, but improved anode catalysts are needed. In this study, a MnS/MnO2 heterostructure with oxygen vacancies supported by carbon cloth was synthesized, which showed lower charge transfer resistance and higher oxygen evolution potential. The catalyst achieved nearly 100% removal of methyl orange in 30 minutes with high mineralization current efficiency and low energy consumption. Oxygen vacancies increased the positive charge of Mn atoms, enhancing the catalyst activity. The study provides a promising strategy for improved electrocatalytic removal of manganese dioxide.

Summary: By calculating and grading the hue angle of a water body, a Forel-Ule index (FUI) can be obtained, which provides a comprehensive statement of water condition. Using MODIS imagery, hue angles are extracted with better accuracy than the literature's method. It is found that FUI changes in the Bohai Sea have correlated consistently with water quality, and the decreasing trend of non-excellent water quality areas in the Bohai Sea was highly correlated with FUI (R2 = 0.701) during the government-dominated land-based pollution reduction program (2012-2021).

Summary: Wild waterbirds, particularly waterfowl, are a reservoir for avian influenza viruses, and transmission occurs at the interface between agriculture and wildlife. Environmental changes in the East Asian-Australasian Flyway, including rice paddy distribution, may affect the movements of migratory birds and disease transmission risk. Dynamic Brownian Bridge Movement Models were used to predict changes in waterfowl distribution based on rice distribution data. Results showed that small decreases in rice agriculture could lead to habitat loss for waterfowl in southeast China, while increases in rice paddies in northeast China could provide new areas for waterfowl. The study highlights the potential implications of changing waterfowl distribution on avian influenza transmission.

Summary: Invasive Spartina species pose serious threats to global coastal ecosystems. A global meta-analysis of 102 studies found that physical measures quickly suppressed Spartina, but their effectiveness declined over time. Chemical measures decreased the abundance and growth of Spartina to a lesser degree in the early stage, but the effectiveness increased over time. Different management measures did not significantly decrease the diversity of native biota on the whole, but native-plant diversity significantly decreased with time after physical control.

Summary: Biological invasions, especially by Spartina alterniflora, are significantly impacting the structure and functions of coastal ecosystems in China. Urgent efforts to control the spread of this invasive species are hindered by the lack of time-series data. By using satellite images, this study successfully generated annual maps of Spartina saltmarshes from 1985 to 2020, revealing a continuous expansion of Spartina along the coast. The invasion history and frequency of changes were found to be influenced by latitude, with low latitudes experiencing longer and more frequent invasions. Human interventions have contributed to the decline in certain areas, but natural spread remains the primary driver of its extensive invasion.
