Abstract

Soil respiration (RS) responds to changes in plant and microbial activity and environmental conditions. In arid ecosystems of the southwestern USA, soil moisture exhibits large fluctuations because annual and seasonal precipitation inputs are highly variable, with increased variability expected in the future. Patterns of soil moisture, and periodic severe drought, are often cited as a principal control on ecosystem processes such as RS. To understand the influence of temperature, soil moisture, and other environmental variables on RS, we compared RS and micro-meteorological data from a pinon-juniper woodland at the Sevilleta LTER in central New Mexico during August 2006 to August 2007 and compared four models applied to the data.
