Space Is More Important than Season when Shaping Soil Microbial Communities at a Large Spatial Scale

ABSTRACT The relative importance of spatial and temporal variability in shaping the distribution of soil microbial communities at a large spatial scale remains poorly understood. Here, we explored the relative importance of space versus time when predicting the distribution of soil bacterial and fun...
