Rhizosphere Effect Enhances Belowground Competition of Coastal Invasive <i>Spartina alterniflora</i> With Mangroves.

ABSTRACT: Spartina alterniflora has severely invaded mangroves in China. In order to explore the possible belowground interspecific interaction along with its invasion, the rhizosphere effect enhancing the competition of S. alterniflora neighboring mangroves was hypothesized. Here, both rhizosphere soil of S. alterniflora and bulk soil were collected from the center of S. alterniflora marsh and border sites where S. alterniflora was adjacent to Kandelia obovata and Aegiceras corniculatum, respectively, in both vigorous growth and senescent periods. Soil nutrient properties, rhizospheric low-molecular-weight organic acids (LMWOAs), soil microbiomes, and microbial functional genes were analyzed. Soil total carbon and total nitrogen contents of S. alt
