摘要：

Ammonia-oxidizer numbers decreased under conditions of moisture limitation in litter, fermentation and humus layers of forest soil in the field, but the extent of regrowth after rehydration varied between layers. Nitrosospira 16S rRNA genes were amplified from all layers, regardless of moisture content or soil pH which varied between 4.1 and 5.2. Nitrosomonas spp. were detected less often, but appeared to exhibit mol-e rapid recovery than the Nitrosospira spp, when drought conditions were relieved by rainfall.
