A Drying-Rewetting Cycle Imposes More Important Shifts on Soil Microbial Communities than Does Reduced Precipitation.

The interaction effect between PE treatments and sampling dates was marginally significant for the Shannon ( P = 0.076) and significant for the Simpson ( P = 0.036) diversity indices of fungal communities ( Table 1 ), suggesting that the effect of the precipitation manipulation of fungal communities was dependent on the level of precipitation received and on the soil temperature and plant growth stage.
