Abstract

Abstract: Plant invasion can alter soil organic matter composition and indirectly impact estuary ecology; therefore, it is paramount to understand how plant invasion influences the bacterial community. Here, we present an absolute quantification 16S rRNA gene sequencing to investigate the bacterial communities that were collected from Zostera japonica and Spartina alterniflora covered areas and Z . japonica degradation areas in the Yellow River Estuary. Our data revealed that the absolute quantity of bacteria in the surface layer was significantly ( p < .05) higher than that in the bottom and degradation areas. Following the invasion of S . alterniflora, the abundances of Bacteroidia, Acidimicrobiaceae, and Dehalococcoidaceaewere enriched in the S . alterniflora sediment. In addition, variations in the composition of sediment bacterial communities at the phylum level were the most intimately related to total organic carbon (TOC), and the content of heavy metals could reduce the abundance of bacteria. This study provided some information to understand the effects of S . alterniflora invasion on Z . japonica from the perspective of microbiome level. Abstract : The absolute quantity of surface layer bacteria was higher than the other area. Spartina alterniflora invasion increased the bacterial community abundance. The Sulfate‐Reducing Bacteria and Flavobacteriaceae are dominant bacteria in seagrass beds.
