摘要：
Studies were done to assess the effects of soil moisture manipulations on CH4 oxidation in soils from a dry alpine tundra site. When water was added to these soils there was a stimulation of CH4 oxidation. This stimulation of CH4 oxidation tool; time to develop. One to three days after water additions no stimulation was observed. Nine days after rewetting, CH4 oxidation was greatly stimulated. This lime delay suggests that methanotrophs grew in response to water additions, or that they take a long rime to recover from metabolically inactive resting stages.
