Inundation Depth Shape Phenotypic Variability of Phragmites australis in Liaohe Estuary Wetland, Northeast China

Inundation shifts plant growth, species diversity and ecosystem stability, but it remains unclear how inundation depth shapes the phenotypic variability of clonal plants in an estuary wetland. To reveal response populations to depth, we calculated variation Phragmites australis using shoot height, leaf length, width, biomass panicle length Liaohe Reproductive allocation was defined by ratio height. Linear regression showed that were negatively correlated with while height (p < 0.0001). Based on data regarding statistical differences traits among P. australis, recognized had generated differentiation. Compared other functional traits, coefficient leaf-related at a high level. Therefore, parameters would be most suitable, they increased area weight support action during floods. Multivariate analysis suggested wetland divided into two clusters, consistent geographical distance morphological similarity. Our results provide novel perspective ecological strategy cloned under change offer theories for conservation restoration estuarine ecosystems.
