Changes in Bacterial Communities and Their Effects on Soil Carbon Storage in Invasion Areas, Coastal Wetland Bare Flats, and Areas.

is considered an invasive species that has affected the biogeochemical circle of carbon in coastal wetlands around the world. Nevertheless, it is still unclear how invasion affects the carbon storage capacity of coastal wetlands as carbon pools through bacterial changes. Herein, bacterial communities and soil carbon content in coastal wetland native areas and invasion areas were detected. It was found that an invasion brought more organic carbon and resulted in the increase in in bare flats and areas. When decomposition capacity was not sufficient, large amounts of organic carbon may be stored in specific chemical forms, such as monosaccharides, carboxylic acids, alcohols, etc. The results have also shown that soil bacterial communities were highly similar between the bare flat and invasion area, which is extremely conducive to the rapid growth of . However, an invasion would decrease total carbon contents and inorganic carbon contents in the area. This is not conducive to the stability of the soil carbon pool and soil health. These findings may complement, to some extent, the shortcomings of the interaction between and bacterial communities, and their joint effect on soil carbon storage.
