“…For the 15 N-labeled plant samples, seeds and corms were selected in the laboratory, washed thoroughly, dried with absorbent paper, blanched at 105 • C for 2 h, and then dried at 60 • C for 48 h until reaching a constant weight (Li et al, 2020). The aboveground parts, underground parts, seeds, and tubers were individually weighed and recorded.…”

“…Furthermore, Li et al. (2020) also noted out in his study that more physiological characteristics need to be examined in the future to identify species‐specific adaptive strategies under hydrological stress. Therefore, this study focuses on the environmental adaptation strategies of S. mariqueter , examining nitrogen allocation in various parts of S. mariqueter under elevation differences to gain a deeper understand of its ecological adaptations of S. mariqueter .…”

“…In areas below an elevation of 2.38 m, S. mariqueter lacks reproductive morphology. Between 2.38 and 2.50 m, there is a notable increase in resource allocation toward asexual reproduction by these plants (Li et al., 2020; Yong & Zhang, 1992). With increasing elevations, S. mariqueter is gradually replaced by Phragmites australis ( P. australis ).…”

“…In this habitat, there is a higher allocation of resources by the plants toward sexual reproductive parts (Yong & Zhang, 1992). The reproductive organ yield of S. mariqueter , including seeds and corms, gradually reached the maximum, with the altitude threshold for reproductive organ yield being 0.25–0.30 m higher than that for morphological and biomass growth (Li et al., 2020). This ultimately determined the optimal life history pattern of S. mariqueter , which adapts to changes in wetland elevation (Yong & Zhang, 1992).…”

BackgroundEcological restoration of coastal wetlands has become particularly urgent worldwide as wetland areas have declined dramatically over the past two decades.AimsTo understand the nitrogen allocation strategy of Scirpus mariqueter (S. mariqueter) and provide theory support for future wetland management and restoration.MethodsThe study investigated the response mechanism of S. mariqueter to altitude spatial changes in Nanhui Dongtan from 2017 to 2019 using remote sensing imagery and field surveys. The ecological adaptability of S. mariqueter at different elevations (denoted as A, B, and C for elevations 2.40, 3.15, and 3.49 m, respectively) was analyzed through 15N stable isotope tracing technology. In July and September 2020, 15N‐enriched urea solution was uniformly sprayed onto the leaf surfaces of S. mariqueter at different sites. Plant samples were collected at the end of July and September, and the aboveground, belowground, seed, and rhizome biomass were measured, followed by 15N isotope tests.Results(1) From 2017 to 2019, the biomass of S. mariqueter significantly increased in the elevation change of 0.44–0.48 m, with the maximum aboveground biomass increase of 488.70 g dm−2. The density also increased significantly in the elevation change of 0.13–0.43 m, peaking at 674.02 plants m−2; (2) during the growing period, the biomass of A, B, and C increased. The aboveground portion of the 15N allocation rate accounted for 74%–84%. The belowground portion of the 15N allocation rate positively correlated with elevation; (3) during the reproductive period, elevation positively correlated with the 15N distribution rate of seeds and corms, as well as the biomass allocation rate of seeds and aboveground portions. The 15N allocation rate of the corms was higher than that of seeds. Additionally, elevation exhibited a negative correlation with belowground biomass allocation rate. (4) Point A has the highest difference of above and belowground biomass proportion, and 15N isotope allocation. Area of point A is the critical area affecting vegetation expansion and should be paid more attention in the future work of coastal management and restoration.ConclusionThere is an adaption strategy of S. mariqueter that affects the plant‐soil interaction and the biogeomorphological development process along the elevation gradient.
