Abstract
The legacy impacts of past climates on the current distribution of soil microbial communities are largely unknown. Here, we use data from more than 1,000 sites from five separate global and regional datasets to identify the importance of palaeoclimatic conditions (Last Glacial Maximum and mid-Holocene) in shaping the current structure of soil bacterial communities in natural and agricultural soils. We show that palaeoclimate explains more of the variation in the richness and composition of bacterial communities than current climate. Moreover, palaeoclimate accounts for a unique fraction of this variation that cannot be predicted from geographical location, current climate, soil properties or..
