Summary: Seagrass meadows are vital ecosystems that are under severe threat due to increasing extreme climate events. The study focused on the impact of super typhoon Lekima on Zostera japonica in the Yellow River Delta, resulting in a significant decrease in distribution area and loss of soil organic carbon and nitrogen. Despite suitable environmental conditions, recovery of the seagrass meadows is deemed impossible without restoration efforts. Long-term monitoring is essential for providing new insights and future protection of these ecosystems.

Summary: The study showed that heavy metals in coastal sediments and seagrass mainly come from natural sources, with As and Hg posing the highest ecological risk. The concentrations of Cr, Ni, Cu, Zn, Cd, and Hg were higher in leaves of E. acoroides than in roots, and Zn, Cd, and Hg had high bioconcentration factors.

Summary: This study analyzes the carbon stock in the Isle of Wight, Solent, and adjacent harbours in southern England, including organic carbon in sediment and plants. The results contribute to global blue carbon research by providing the first direct assessment of sediment carbon stocks in intertidal seagrass meadows in the Solent region. The study also compares sediment organic carbon and organic matter content within seagrass meadows and adjacent mudflats, and suggests that organic matter content can be confidently used as a proxy for sediment organic carbon values in intertidal seagrass meadows. These findings support the inclusion of the region's seagrass meadows in conservation and restoration projects to conserve carbon stored in their soils and enhance their future carbon uptake potential.

Summary: In this study, the growth, Cd enrichment, and antioxidant enzyme activity of duckweed were investigated under Cd stress. The results showed that both high-Cd-tolerance duckweed (HCD) and low-Cd-tolerance duckweed (LCD) strains hyper-enriched with Cd. Transcriptome analysis revealed significant differences in gene expression between HCD and LCD, with antioxidant system being significantly expressed in HCD but not in LCD. Alpha-linolenic acid metabolism likely plays an important role in Cd detoxification in duckweed. These findings contribute to the understanding of Cd tolerance mechanisms in hyperaccumulator plants and lay the foundation for future phytoremediation studies.

Summary: Seagrass restoration in open coast environments is challenging due to high biomass requirements. The checkers design aims to optimize biomass usage by transplanting fewer sods in a checkerboard pattern. This study shows the promise of the checkers method for large-scale restoration, but careful consideration of location or storm-mitigating measures is essential.

Summary: The study showed that anoxic stress significantly reduced leaf Fv/Fm and had a negative impact on photosynthesis and growth of Zostera marina. Metabolomic analysis revealed promotion of glycolysis process and inhibition of the TCA cycle under anoxia, indicating a complex strategy of acclimation and adaptation in seagrass to resist anoxic stress.

Summary: Seed germination and seedling establishment of Zostera marina L. are significantly influenced by water depth and seed burial depth, with seeds buried at shallower depths in sand showing higher percentages of successful germination and establishment. However, once plants are established, sediment type and burial depth do not play a decisive role in plant growth.

Summary: Based on observations and experiments on eelgrass seeds in Swan Lake and Qingdao Bay in northern China, it was found that although the seeds matured at the same time, their germination time varied. Further analysis revealed that this difference was determined by internal molecular mechanisms rather than environmental factors. Comparative transcriptome analysis showed that eelgrass seeds in Swan Lake had a deeper dormancy depth and required the mobilization of more related genes to break dormancy and initiate germination compared to seeds in Qingdao Bay.

Summary: This study conducted field sampling over 19 months in a large seagrass meadow in a eutrophic bay in northern China to investigate eelgrass population reproduction status and ecological interactions. The results showed that asexual growth was important for maintaining existing meadows, while sexual reproduction played a critical role in colonization of new areas. Nutrient uptake by seagrass might reduce the probability of a red tide in the study area.

Summary: This study investigated the distribution of eelgrass at its southern limits on the eastern coast of China and found a northward shift in the southern limit. Further experiments showed that high water temperatures negatively affected eelgrass growth and caused shoot mortality.

Summary: This study examined the toxic effects of copper and cadmium on eelgrass at multiple levels. The results showed that copper was more toxic to eelgrass than cadmium. High temperatures increased heavy metal damage, while low temperatures inhibited damage. Copper and cadmium had a synergistic effect on photosynthesis. Transcriptome analysis revealed severe damage to the photosynthetic system under cadmium stress, while copper stress resulted in up-regulation of genes related to glutathione metabolism. Recovery experiments showed that the damage caused by short-term copper and cadmium stress was reversible. These findings provide insights into the heavy metal toxic effects and resistance strategies of eelgrass, highlighting its potential for phytoremediation, especially for cadmium.

Summary: This study proposes a method to evaluate the seed provision efficacy of detached eelgrass reproductive shoots. Mature seeds were collected from detached eelgrass reproductive shoots in Swan Lake, China, using in situ net cages. The results showed that each detached reproductive shoot produced an average of 50 viable seeds, and the potential seed yield overestimated the actual seed yields. The simplest treatment (a single reproductive shoot) was convenient and robust for this method, indicating its potential for improving the efficiency of seed use in restoration projects.
