Contribution of environmental and biological factors to bacterial community structure and stability in a subalpine lake.

ABSTRACT: Bacterial community play an essential role in regulating water quality and the global biogeochemical cycle in aquatic ecosystems. However, how trophic interactions (i.e., biotic factors) regulate the diversity and composition of bacterial community in lake ecosystems remains unknown. Here, we employed DNA meta-barcoding of water samples to explore the impact of bacterivorous protozoans on the bacterial community. The results showed significant seasonal variations in the diversity and composition of both bacterial and protist communities. The composition of bacterivorous protozoans was identified as the primary predictor for the bacterial community alpha diversity in spring and summer, and for beta diversity in spring and autumn, indicating that biotic interactions play a greater role in dr
