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...

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 different depths of snow cover.

Conversely, bacterial diversity in soil samples under low and with no snow cover decreased after the simulated FT cycles.
