Preliminary budget of methane emissions from natural wetlands in China

Effects of soil warming, rainfall reduction and water table level on CH 4 emissions from the Zoige peatland in China

“…The CH 4 emissions that we measured across all experimental conditions, which averaged 0.57 mg C m À2 h À1 , are similar to those measured in the Donggi Cona Lake basin (0.54 mg C m À2 h À1 ) on the northeastern Tibetan Plateau (Jin et al, 1999), but lower than emissions measured in another study (2.96 mg C m À2 h À1 ) in the same region (Ding et al, 2004) (Table 1). The different results may reflect the high spatial-temporal variability in CH 4 emissions from peatlands (Dinsmore et al, 2009b).…”

Grazing intensity and soil depth effects on soil properties in alpine meadow pastures of Qilian Mountain in northwest China

“…Soil organic carbon (SOC) was analyzed using standard procedures for determination of SOC content (Ding et al 2004;Long et al 2010). Total nitrogen (TN) was measured by the Kjeldahl method (Hirota et al 2005), available nitrogen (AN) was extracted using the micro-diffusion method (Hirota et al 2005).…”

Floating Aquatic Macrophytes Decrease the Methane Concentration in the Water Column of a Tropical Coastal Lagoon: Implications for Methane Oxidation and Emission

“…These results suggest a diel variation of methane oxidation and methane emission, depending on the intensity of light in freshwater ecosystems. Diel variation in methane emission by emergent aquatic macrophytes has been observed 56,57 , but the physiological mechanisms that control methane release to the atmosphere from plants are not completely understood. The stomata opening is controlled by factors that present diel variation such as light 58 .…”
