Analysis of the differences and driving factors of bacterial community structure and diversity in multiple habitats of the Qingshui River ecosystem in Ningxia, China.

This study investigated bacterial community structure in surface water, sediment, and riparian soil habitats within the Qingshui River Basin in Ningxia, China, across normal, wet, and dry periods using 16S rDNA sequencing. Our findings revealed habitat-specific microbial dynamics, with surface water exhibiting significantly lower α-diversity compared to sediments and riparian soils (e.g.

[Bacterial Community Structure of Typical Lake Sediments in Yinchuan City and Its Response to Heavy Metals].

Lake wetlands are extremely important and special ecosystems, which are important for regional water resource storage, environmental protection, and biodiversity maintenance. Sediment bacteria are an important component of lake ecosystems and are a major driver of biogeochemical cycling in lakes. In order to investigate the community structure of bacteria in typical lake sediments in Yinchuan City and their influencing factors, three typical lakes in Yinchuan City (Yuehai Lake, Mingcui Lake, and Xiniu Lake) were selected for the study and surface sediments were collected in January, April, July, and October 2021.
