Chemosynthetic and photosynthetic bacteria contribute differentially to primary production across a steep desert aridity gradient
Desert soils harbour diverse communities of aerobic bacteria despite lacking substantial
organic carbon inputs from vegetation. A major question is therefore how these communities …
