This research will investigate how marsh plant communities with different dominant species might function to structure microbial communities in marsh sediments, thereby altering biogeochemical patterns, CO2 uptake (or release) and processing of atmospheric N inputs resulting from human activities. The role of estuarine marshes, such as those studied here, in regulating C and N cycles is of global importance. Moreover, determining whether marshes dominated by different plant species (Spartina alterniflora and Phragmites australis) process CO2 and N inputs differently via their effects on sediment microbial communities addresses an important scientific question. t mechanisms, root porosity, and in sediment microbial community composition and functional ability. This study represents a novel approach to improving understanding of wetland plant-microbe interactions. It could contribute information useful designing coastal wetland restoration projects and management efforts.

这项研究将调查具有不同主要物种的沼泽植物群落如何在沼泽沉积物中构造微生物群落，从而改变生物地球化学模式，二氧化碳吸收（或释放）以及人类活动引起的大气N输入的处理。 河口沼泽（例如这里研究的河口）在调节C和N周期中的作用至关重要。 此外，确定沼泽地以不同的植物物种（Spartina Alterniflora和Phragmites Australis）为主导的过程CO2和N输入通过对沉积物微生物群落的影响有所不同，这是一个重要的科学问题。 T机制，根孔隙度以及在沉积物微生物群落组成和功能能力中。这项研究代表了一种新的方法，可以提高对湿地植物菌相互作用的理解。 它可以为设计沿海湿地修复项目和管理工作提供有用的信息。
