Afforestation can lower microbial diversity and functionality in deep soil layers in a semiarid region

Xiaorong Wei
Afforestation is an effective approach to rehabilitate degraded ecosystems, but often depletes deep soil moisture. Presently, it is not known how an afforestation-induced decrease in moisture affects soil microbial community and functionality, hindering our ability to understand the sustainability of the rehabilitated ecosystems. To address this issue, we examined the impacts of 20 years of afforestation on soil bacterial community, co-occurrence pattern and functionalities along vertical profile (0-500 cm depth) in a semiarid region of...
