Quantitative Comparison of In Situ Soil CO2 Flux Measurement Methods
Development of reliable regional or global carbon budgets requires accurate measurement of soil CO2 flux. We conducted laboratory and field studies to determine the accuracy and comparability of methods commonly used to measure in situ soil CO2 fluxes. Methods compared included two static techniques, sodium hydroxide (NaOH) and soda lime as CO2 traps; a multichamber open dynamic system (OC) wit...

متن کاملStatistical properties of random CO2 flux measurement uncertainty inferred from model residuals
Information about the uncertainties associated with eddy covariance measurements of surface–atmosphere CO2 exchange is needed for data assimilation and inverse analyses to estimate model parameters, validation of ecosystem models against flux data, as well as multi-site synthesis activities (e.g., regional to continental integration) and policy decisionmaking. While model residuals (mismatch be...
متن کاملEvaluating changes in the plant communities after overgrazing in the Golbahar plain, northeast of Iran
Overgrazing affects plant communities, and is a significant disturbance factor in arid and semi-arid regions. The immediate changes of plant communities after overgrazing in the disturbed arid ecosystems of Iran have been poorly studied. We recorded data from 100 random samples before and after overgrazing in the Golbahar plain located in the northeastern Iran to determine the changes in the pl...
متن کاملMultitrophic Effects of Elevated Atmospheric CO2 on Understory Plant and Arthropod Communities
Rising levels of atmospheric [CO2] will directly affect the responses and community composition of plants. However, few studies have examined how these changes to plant communities will alter insect communities that rely on them. Here, we report on a study that examined the community-level responses of plants, herbivores, detritivores, predators, parasitoids, and omnivores to increased [CO2] at...
