Summary: This study reviewed the influence of floodplain inundation magnitude, frequency, and duration on aquatic ecosystem metabolism and carbon flux. The results showed that large floods transferred more carbon from floodplains to river channels, high turbidity floodplain habitats reduced rates of GPP due to restricted light, and nutrient levels were positively correlated with GPP in floodplain wetlands. There was insufficient evidence to support causal relationships for other hypotheses, including the effects of floodplain inundation frequency and duration.

Summary: Tidal flats are widely distributed and provide various ecosystem services. The global average carbon accumulation rate in tidal flats is 129.8 g C m(-2) yr(-1), with an average carbon content of 86.3 Mg C ha(-1). If tidal flats continue to be lost and disturbed sediment carbon continues to be remineralized, a significant amount of carbon will be lost annually, leading to CO2 emissions in the water column and atmosphere.

Summary: We examined the sources and chemical stability of soil organic carbon (SOC) in natural and created marshes along the Gulf coast of Louisiana. The results showed that SOC in natural marshes mainly came from local vegetation, while in created marshes, it originated from a large amount of sediment. However, the accumulation rate of SOC was higher in natural marshes compared to created marshes. Therefore, preserving and augmenting natural marshes can improve carbon storage in marsh ecosystems.

Summary: Our research aimed to find new resources for bacterial nitrification inhibitors (BNIs) and investigate their mechanisms of action through multiomics approaches. We discovered that leaf extracts from Suaeda salsa (both red and green phenotypes) in the Yellow River Delta showed strong nitrification inhibition ability. We identified oxalic acid (OA) and protocatechuic aldehyde (PA) as novel BNIs, constructed their synthetic pathways, identified key genes involved in their synthesis, and revealed their inhibition mechanisms on Nitrosomonas europaea using transcriptomics and metabolomics. Another finding was that PA exhibited nitrification inhibition effects in saline-alkali soil, cinnamon soil, and red soil, with the most effective inhibition in saline-alkali soil, while OA only showed nitrification inhibition effects in red soil.

Summary: Understanding how geomorphic structures influence habitat invasibility is crucial for predicting invasive species range-expansion. This study focuses on the role of tidal channel meanders in regulating the invasion of Spartina alterniflora in the Yellow River Delta, China. The findings indicate that hydrodynamic variables, soil abiotic stresses, and propagule pressure play significant roles in facilitating or inhibiting Spartina invasion. The meandering geomorphic structures of tidal channels can act as stepping-stones for Spartina's landward spread.

Summary: Freshwater ecosystems are at risk due to the accumulation of microplastics, but the effects on aquatic plant metabolism are not well understood. In this study, Spirodela polyrhiza was exposed to polyvinyl chloride (PVC) microplastics, and the changes in plant traits and metabolism were monitored. The results showed that high doses of PVC microplastics reduced root elongation and leaf multiplication, as well as anthocyanin and nitrogen contents. Metabolomics analysis revealed differential metabolites involved in carbon, nitrogen, amino acid, and lipid metabolism. PVC microplastics had concentration-related toxicological effects on plant traits and nutrient metabolism, with implications for the nitrogen cycle in aquatic plant habitats.

Summary: River stage fluctuations enhance nitrogen cycling in riparian zones. Water table fluctuation zone facilitates coupled nitrification and denitrification, leading to increased nitrate removal. Net nitrate reduction rate in groundwater is influenced by the number of river stage fluctuations, cumulative water influx, and other factors. The presence of oxygen diffusion is crucial for accurately estimating nitrate removal capacity in riparian zones.

Summary: Plant invasion can significantly affect the accumulation of microbial necromass carbon (MNC) in coastal Blue Carbon ecosystems. The invasion reduced the contribution of MNC to soil organic carbon (SOC) in salt marshes but increased the accumulation of microbial residues in mangrove habitats. Fungal-derived MNC was more abundant than bacterial-derived MNC, and the contribution of fungal MNC decreased with increasing mean annual temperatures. Soil carbon-to-nitrogen ratio and soil texture had negative effects on MNC/SOC, indicating the importance of soil nutrient status and physical protection in regulating MNC accumulation in coastal wetlands.

Summary: Plant invasion has a profound impact on microbial-driven processes in the ecosystem, but little is known about the seasonality of soil microbial communities and their assembly under plant invasion. This study examined coastal salt marshes in the Yellow River Estuary, North China, and characterized the bacterial and fungal communities and their seasonal variance using metabarcoding sequencing. The results showed strong seasonal variances in microbial communities, but plant invasion reduced the seasonal variation strength of soil bacteria. Soil pH was found to be the key abiotic factor driving the seasonal changes in bacteria and fungi. These findings reveal the strong seasonal variability of different soil microbial constituents in plant-invaded coastal salt marshes and suggest the linkage between microbial community assembly and microbial-mediated functions in the context of plant invasions.
