Biophysics of Cold Adaptation and Acclimatization: Microbial Decomposition.
The intent of the proposed research was to further ellucidate decomposition processes attributed by soil fungi in an Arctic terrestrial environment as those processes relate to the structure and function of decomposition in cold dominated peat soil. The approach was novel in that it was to examine t...
