spatial and seasonal variations of acidobacteria / actinobacteria collected from soils of alpine

bacteria play a major role in environmental processes. however, the spatial and seasonal variations and environmental impact factors on different bacterial groups have been poorly studied. in the present study, we compared the spatial and seasonal variations of two bacterial groups (acidobacteria, actinobacteria) from early snow melt and late snow melt locations in alpine tundra. the results revealed that ph is the essential factor for structuration of two bacterial groups. the pattern of acidobacteria is very similar to the overall bacterial communities in our previous study, while both bacterial communities are highly influenced by seasonal variations with an independent pattern.
