Description
Summary:This study aimed at determining the impact of long-time elevated CO sub(2) fumigation on fungal communities in a temperate forest soil. In addition to the CO sub(2) concentration, both time and its interaction with the CO sub(2) affected the activity of 1,4-b-N-acetylglucosaminidase that is mainly of the fungal origin in the soil. No significant change in Shannons indexes (from 18S rDNA-PCR-DGGE) was observed between the ambient and elevated CO sub(2) treatments. Analysis of time-course indicated that the succession of soil fungal community was altered by the elevated CO sub(2) fumigation, and the variations in the soil samples under Pinus koraiensis Sieb. et Zucc were larger than those under the Pinus sylvestriformis (Takenouchi) T. Wang ex Cheng samples. The results suggest that the increase in atmospheric CO sub(2) concentrations could alter the temporal patterning of soil fungal communities.
