Effects of water flow conditions on soil properties and microbial communities in the lower Heihe river Basin, Northwest China.

ABSTRACT:

Background

Effective hydrological management in arid ecosystems requires a comprehensive understanding of how water flow conditions influence biota and ecosystem processes. However, the responses of soil microbial communities remain poorly understood. This study aims to evaluate whether, and to what extent, a 20-year difference in flow regimes affects soil microbial diversity, composition, and function. The composition of the soil microbial community and the factors shaping it were investigated in two arid riparian zones (East River and West River) of the lower Heihe River Basin using 16 S rRNA amplicon high-throughput sequencing.

Results

The dominant phyla of the bacterial, fungal, and archaeal communities were Proteobacteria, Ascomycota, and Euryarchaeota, respectively. Co
