Summary: The study reveals the different lineages of genetic diversity in common reed in the Yellow River Delta in China and highlights the importance of hydrochory dispersal and habitat selection in influencing genetic diversity. The results also suggest natural selection by habitat conditions and salinity as a significant selective stressor on the plant lineages.

Summary: The decomposition rate of plant litter is mainly controlled by litter quality and environmental factors. In this study, it was found that higher salinity under inundation conditions can lead to faster decomposition rates, while the ratio of nitrogen to phosphorous showed an upward trend during the process. Additionally, both water chemical oxygen demand and NH3-N concentration were inversely correlated with salinity.

Summary: Plant fine-root decomposition is a key process for nutrient reentry into the soil. Previous studies have focused on major elements, with limited attention given to trace elements. This study investigated the decomposition dynamics of 10 mineral elements during fine-root decomposition in moso bamboo. Results showed that root diameter and decomposition time significantly affected the remaining percentages of certain elements.

Summary: The Yellow River Delta is the largest and youngest estuarine and coastal wetland in China and bacterial communities in the soil are significantly influenced by factors related to seawater erosion, nutrient levels, and human disturbance. Seawater erosion drives the variations of marine oligotrophic bacterial communities in early succession stages, while nutrient availability enhances riverine copiotrophs in the late stages.

Summary: Coastal tidal flats are important ecosystems, but they are highly vulnerable to tidal dynamics, sea-level rise, and human activities. This study examined the hydrodynamics, sediment transport, and morphological changes on two tidal flats in the Yellow River Delta with different tidal regimes. The results showed that longer inundation periods under diurnal tides led to more sediment deposition, while semi-diurnal tides resulted in increased wave impact and tidal flat erosion due to lower water depths. These findings highlight the joint role of tidal regime and powerful waves in controlling sediment availability and tidal flat evolution. This has implications for managing erosion and restoring vegetation in the Yellow River Delta.

Summary: The study revealed that changes in UV radiation have significant effects on litter decomposition and nutrient release, with the impact varying depending on the type of litter. Additionally, as the decomposition progresses, the magnitude of mass loss and nutrient release also changes accordingly.

Summary: The study investigated the water, salt, and stoichiometry characteristics of different halophytes and soil systems in the Yellow River Delta. Results showed differences in the water sources and nutrient utilization among the plants, along with varying correlation patterns between plants and soil layers. The findings contribute to a better understanding of the adaptability of halophytes in this region.

Summary: Litter decomposition is a critical process in ecosystems, impacting carbon storage, nutrient availability, and forest productivity. This study investigated the effects of soil warming on litter decomposition rates in a subtropical forest in China. The results showed that soil warming did not affect litter mass loss during the initial stage but reduced it during the later stages. The study also found that the reduction in litter decomposition rates was likely due to the negative effects of warming on extractable organic carbon, microbial biomass, and litter enzyme activities.

Summary: Analysis of data from a variety of pine species, Norway spruce, and birch showed that Norway spruce and lodgepole pine had higher Mg concentrations in their litter compared to Scots pine. The relationship between Mg concentration and accumulated mass loss followed a quadratic function, with temporary Mg limitation during decomposition. The net release rate of Mg was negatively linearly related to initial Mg concentration.

Summary: The invasion of Spartina alterniflora affects the SOC pool and stability in the wetlands of the Yellow River Delta. While the invasion may promote the increase of the SOC pool, it weakens its stability. Aromatic compounds in the soil are decreasing while the SOC pool is increasing.
