Special Issue Information

Dear Colleagues,

Aquatic macrophytes and algae play a significant role in improving water quality and inhibiting microalgal blooms. At the same time, they can provide habitats and foraging places for aquatic animals, effectively maintaining the stability of ecosystems and biodiversity levels. Therefore, aquatic macrophytes and algae are often used in the restoration of intertidal zones, lakes, and river ecosystems. On the contrary, some aquatic macrophytes and algae in natural ecosystems form dominant species, which then lead to large-scale ecological disasters such as green tides and golden tides, with a significant impact on the management and healthy development of regional ecosystems.

This Special Issue aims to provide an academically inclusive platform for open discussions among scholars. In this Special Issue, we welcome original research articles and reviews with a suggested minimum word count of 4,000 words. Additionally, scoping review-type articles can be submitted as review articles.

The research topics may include (but are not limited to) the following: (1) the key role of aquatic macrophytes and algae in ecosystems; (2) the application of aquatic macrophytes and algae in ecological restoration engineering; (3) allelopathy of aquatic macrophytes and algae to algal bloom (red tide and Cyanobacteria bloom) species; (4) ecological risks and management measures associated with algal blooms or invasive species; (5) the issues of biodiversity conservation and ecological management to be considered in the process of ecological restoration, as well as microbial biomarkers and their applications in reconstructing marine ecological environments; (6) the functions of symbiotic microorganisms in the growth and death processes of aquatic macrophytes and algae, and the relationship between microorganisms and the stability of aquatic ecosystems. In addition, we encourage scholars to submit other articles related to the above themes. We invite you to contribute to the development of the academic subject in this field.

We are looking forward to receiving your contributions.

Interannual Variations in Soil Bacterial Community Diversity and Analysis of Influencing Factors During the Restoration Process of Scirpus Mariqueter Wetlands

Due to human activities and the invasion of Spartina alterniflora, the population of Scirpus mariqueter (S. mariqueter) in the Yangtze River Estuary has gradually declined. To address this issue, numerous restoration efforts have been undertaken. To investigate the changes and influencing factors of soil bacterial communities during the restoration of S. mariqueter wetlands, we selected S. mariqueter populations as the research focus and divided the samples into two years, S1 and S2. High-throughput sequencing technology was employed for observation and analysis. The results revealed that from S1 to S2, soil bacterial diversity in the S. mariqueter wetland increased significantly and displayed clear seasonal patterns. The dominant bacterial phyla included Proteobacteria, Bacteroidota, Firmicutes, and Acidobacteriota. Among these, Proteobacteria had the highest relative abundance, while Acidobacteriota showed the most pronounced increase, surpassing Bacteroidota and Firmicutes to become the second most abundant group. Redundancy analysis (RDA) indicated that soil organic matter and electrical conductivity were the key factors influencing the composition and diversity of the soil bacterial community, with Acidobacteriota playing a dominant role during wetland restoration. In conclusion, during the ecological restoration of the S. mariqueter wetlands, attention should be given to environmental factors such as soil organic matter and electrical conductivity, while the regulatory role of Acidobacteriota in wetland soils should not be overlooked. This study provides a microscopic perspective on the interactions between microbial diversity and ecosystem functions in coastal wetlands, offering valuable guidance for the ecological restoration of degraded wetlands.

This study used microscopy-based quantitative enumeration to investigate the effects of large-scale Sargassum fusiforme cultivation on coastal water quality and phytoplankton communities. Data from April (cultivation period) and June (non-cultivation period) in 2018 and 2019 showed that cultivation increased pH and dissolved oxygen (DO). It also reduced nitrate–nitrogen (NO3–N), nitrite–nitrogen (NO2–N), phosphate–phosphorus (PO4–P), total phosphorus (TP), and silicate–silicon (SiO3–Si) concentrations. These changes indicate improved coastal water quality from S. fusiforme cultivation. Nutrient levels rose again during the non-cultivation period. This suggests that water purification decreased without cultivation. Cultivation also lowered the dominance of Skeletonema costatum. This led to a more diverse and stable phytoplankton community. Microscopic observation is valuable for quantifying larger phytoplankton species, and plays an important role in ecological monitoring. These findings provide insights for sustainable aquaculture and ecological restoration. Full article

Located within the subpolar front (SPF) zone, the eastern coast of Korea is subject to frequent environmental changes on both spatial and temporal scales. In this study, we analyzed seasonal changes in the algal community structure and related environmental factors at two sites, Chodo (CD) and Sageunjin (SG), which were influenced by cold and warm-water masses, respectively, in the SPF zone. Sea surface temperature (SST) exhibited greater seasonal change in CD, whereas significant wave height was higher in SG. The salinity and nutrient concentrations decreased during summer and increased in winter at both sites. Seasonal shifts in the dominant species were distinct, with turf species positively correlated with SST dominating the intertidal zone of SG during winter, and canopy species were associated with nutrient concentrations dominating the intertidal zone of CD. Bryopsidales, which was positively correlated with the N:P ratio, dominated the SG subtidal zone in summer, whereas Fucales, which was positively correlated with the SST, dominated the CD subtidal zone. These results enhance our understanding of seaweed responses to environmental changes in SPF zones and provide a basis for predicting future changes in coastal ecosystems. Full article
