Summary: Seagrasses are highly productive ecosystems that provide numerous benefits to the environment and people. This study evaluates the carbon storage capacity of Zostera noltii and Zostera marina in intertidal seagrass meadows in Scotland, finding that seagrass areas show enhanced carbon storage compared to reference unvegetated ones. However, the variability in carbon storage across depth, sites, and estuaries indicates a need for further research and effective management strategies.

Summary: This study investigated the microbial community structure and diversity of Zostera marina growing in Futtsu bathing water, Chiba prefecture, Japan. The composition of leaf-attached microbes changed with the relative age of the eelgrass leaf. The microbial communities of marine particles resembled those of eelgrass leaves, suggesting that leaf-attached microbes may derive from suspended particles and move between eelgrass leaves and the water column.

Summary: The presence and strength of trophic cascades involving sea otters in southeast Alaska may not be generalized, potentially due to local scale factors such as spatial heterogeneity, low resource availability, and non-linear food chains in southeast Alaska seagrass communities. Correlation analyses suggest further interactions among biological and environmental variables in southeast Alaska seagrass communities, highlighting the need for local assessment on the ecology and management of apex-predator populations.

Summary: A comparative study was conducted on eelgrass populations in Mashanli and Moon Lake to investigate their adaptation strategies. Results showed that eelgrass in Mashanli had smaller leaves and shorter internodes, while developing thicker leaf epidermis and higher vascular bundle area. These adaptations help the eelgrass cope with high-energy environments and resist waves and currents.

Summary: Increased water turbidity is a primary cause of seagrass meadows loss. This study quantified the interactive influence of different combinations of turbidity and duration on Zostera marina plants, revealing a strong inverse relationship between turbidity and duration that affects the survival and growth of the plants. The study indicates that short-term periods of increased water turbidity can have long-term effects on the survival of Z. marina plants.

Summary: In this study, a short-term field sampling was conducted, complemented with time integrating stable isotope analysis, to holistically investigate the status and ecological interactions in a remote NE Atlantic Zostera marina meadow. The study found high nutrient water concentrations, large biomass of fast-growing, ephemeral macroalgae, low abundance and biodiversity of epifauna, and a food web with thornback ray as intermediate and cod as top predator. The results indicated that the Finnoya Zostera ecosystem is eutrophicated. The study concluded that bottom-up regulation is a predominant driver of change since top-down regulation is generally weak in low density and exposed Zostera ecosystems such as Finnoya.

Summary: Riverine macrophytes play crucial ecological roles in river ecosystems, but their growth models have received relatively limited attention compared to other aquatic or terrestrial plants. This systematic review reveals that current models often overlook important factors such as shading and the role of macrophytes in nutrient cycles. Future research should focus on exploring these factors and developing a conceptual framework to guide macrophyte growth modeling. Emphasizing modularity and accessibility is also important for improving efforts to model and manage riverine ecosystems.

Summary: Bryophytes can play a significant role in ecosystem processes and hold potential as bio-indicators for monitoring environmental pollution. This study examined the effects of NO3- pollution on the elemental composition of aquatic and semi-aquatic bryophytes and identified suitable species as bio-indicators. Higher NO3- concentrations were found in spring water from intense farming and urban areas, positively correlated with N content and delta N-15 isotope ratio in bryophytes. Apopellia endiviifolia and Oxyrrhynchium speciosum were highlighted as promising candidates for bio-indication of aquatic NO3- pollution.

Summary: This study investigated the seed production, seed banking, and germination cues of sub-tropical Vallisneria americana. It was found that the seeds of sub-tropical populations were dormant and could only germinate in the presence of organic material, light, or following scarification. Germination rate was enhanced by the presence of low-oxygen organic sediments and ethanol. These findings suggest a germination strategy focused on exploiting openings in existing vegetation following disturbance.

Summary: Constructed wetlands treating runoff from agricultural catchments can reduce nutrient load of water, but they can also be significant sources of greenhouse gases, especially methane. This study assessed methane emission potentials and phosphorus removal efficiency in a 0.45 ha in-stream surface flow constructed wetland, and analyzed the temporal dynamics of methane emissions and phosphorus removal over a nearly 4-year period. The results showed a clear seasonal dynamic in phosphorus removal efficiency and an increasing trend in methane emissions over the years, with the majority of methane fluxes occurring during the warm period. Maintenance of the wetland and regular removal of aboveground vegetation can reduce methane emissions, and regular sediment removal is also necessary due to phosphorus saturation.

Summary: Nutrient availability and light intensity play important roles in the expansion of amphibious clonal plants from terrestrial to aquatic habitats. High nutrient levels and light conditions promote the growth of the apical portions and overall performance of the clones. Maintaining clonal integration can benefit the expansion of the plants by optimizing resource utilization. These findings have implications for predicting community dynamics and vegetation restoration in ecotones like wetlands.
