Effects of freeze-thaw cycles on High Arctic soil bacterial communities
The projected increase in freeze-thaw frequency associated with warmer temperatures in the High Arctic could affect the dynamics of soil bacterial communities. We report here the effects of freeze-thaw (FT) cycles on High Arctic bacterial communities of soil samples collected from three sites with d...
