Fungi are more sensitive than bacteria to drainage in the peatlands of the Zoige Plateau

The peatlands of the Zoige Plateau are an important global carbon source that is currently under threat as a result of drainage for grazing. How drainage affects the microbial diversity and activity in peatlands is unclear. This study examined the response of microbial communities at two sites to sh...
