“…The water quality status in Danjiangkou Reservoir is directly related to drinking water safety for residents in the associated water-receiving area. Plants in the WLFZ can absorb and retain nutrients such as N and P and are important for protecting the water quality in the Danjiangkou Reservoir [9][10][11]. Microbes play an important role in this process, as they are primary drivers in the biogeochemical cycling of soil elements [12].…”

“…Studies have shown that the presence of plants and soil microbes in the WLFZ increase the absorption and retention of nutrients, such as soil N and P, and promoting their presence is an effective approach for the control of N and P levels and prevention of eutrophication of the Danjiangkou Reservoir [9][10][11]. Microbes are the primary drivers in the biogeochemical cycling of soil elements [12].…”

The water-level fluctuation zone (WLFZ) is a transitional zone between terrestrial and aquatic ecosystems. Plant communities that are constructed artificially in the WLFZ can absorb and retain nutrients such as nitrogen (N) and phosphorus (P). However, the microbial community composition and function associated with this process have not been elucidated. In this study, four artificially constructed plant communities, including those of herbs (Cynodon dactylon and Chrysopogon zizanioides), trees (Metasequoia glyptostroboides), and shrubs (Salix matsudana) from the newly formed WLFZ of the Danjiangkou Reservoir were evaluated. The bacterial community compositions were analyzed by 16S rRNA gene sequencing using a MiSeq platform, and the functions of these communities were assessed via Phylogenetic Investigation of Communities by Reconstruction of Unobserved States (PICRUSt) analysis. The results showed that the bacterial communities primarily comprised 362 genera from 24 phyla, such as Proteobacteria, Acidobacteria, Actinobacteria, and Gemmatimonadetes, showing the richness of the community composition. Planting altered the bacterial community composition, with varying effects observed among the different plant types. The bacterial community functional analysis revealed that these bacteria were primarily associated with six biological metabolic pathway categories (e.g., metabolism, genetic information processing, and environmental information processing) with 34 subfunctions, showing the richness of community functions. The planting of M. glyptostroboides, S. matsudana, and C. dactylon improved the metabolic capabilities of bacterial communities. N- and P-cycling gene analysis showed that planting altered the N- and P-cycling metabolic capacities of soil bacteria. The overall N- and P-metabolic capacity was highly similar between C. dactylon and C. zizanioides samples and between S. matsudana and M. glyptostroboides samples. The results of this study provide a preliminary analysis of soil bacterial community structure and function in the WLFZ of the Danjiangkou Reservoir and provides a reference for vegetation construction in this zone.

“…Revegetation of river margins suffering from artificial water‐level fluctuations is a common restoration goal, aiming at preventing establishment of invasive plant species and reducing leakage of nutrients and sediments from riparian areas (Peng et al. ). When revegetation works, it may influence the composition of fish and macroinvertebrate communities in small streams through the effects on cover, in‐stream habitat, and water temperature (Jowett et al.…”

“…Among habitats of the riparian zone, remediation of waterlevel-fluctuation (WLF) zones is the most difficult due to acute changes of water conditions in the zones, and the depth of relevant researches was insufficient thus far, especially in the aspects of amphibious plant species (Peng et al, 2014). Torpedograss (Panicum repens L.) is a perennial grass widely distributed in tropical and subtropical regions of Asia (Lin, 1990;Hossain et al, 2001), and is often found in wet grounds, and riparian zones of rivers, lakes, and reservoirs.…”
