Sensitivity analysis of a wetland CH4 emission model based on temperate and arctic wetland sites
Together with water vapour and carbon dioxide (CO2), methane (CH4) is an important greenhouse gas, because of its strong global warming potential of 23×CO2 on a 100year time scale. The atmospheric mixing ratio of CH4 has increased with 151 ± 25%, since pre-industrial times. About 60% of the global CH4 emission is of antropogenous origin. From the natural sources (wetlands, termites, oceans, CH4...
متن کاملSensitivity analysis of a wetland methane emission model based on temperate and arctic wetland sites
Modelling of wetland CH4 fluxes using wetland soil emission models is used to determine the size of this natural source of CH4 emission on local to global scale. Most process models of CH4 formation and soil-atmosphere CH4 transport processes operate on a plot scale. For large scale emission modelling (regional to global scale) upscaling of this type of model requires thorough analysis of the s...
متن کاملTemporal Variation in Local Wetland Hydrology Influences Postdispersal Survival of Juvenile Wood Storks (mycteria Americana)
—Since the 1960s, anthropogenic shifts in the timing and distribution of surface-water flows in the Everglades have pushed back the onset of reproduction in Wood Storks (Mycteria americana). Late nesting increases the probability that juveniles leave the colony during the summer rainy season, when water levels are high and prey animals unavailable. We used satellite telemetry to track firstyear...
متن کاملLinking Plant Ecology and Long‐term Hydrology to Improve Wetland Restoration Success
Although millions of dollars are spent restoring wetlands, failures are common, in part because the planted vegetation cannot survive in the restored hydrology. Wetland restoration would be more successful if the hydrologic requirements of wetland plant communities were known so that the most appropriate plants could be selected for the range of projected hydrology at the site. Here we describe...
متن کاملAboveground Net Primary Productivity in a Riparian Wetland Following Restoration of Hydrology
This research presents the initial results of the effects of hydrological restoration on forested wetlands in the Mississippi alluvial plain near Memphis, Tennessee. Measurements were carried out in a secondary channel, the Loosahatchie Chute, in which rock dikes were constructed in the 1960s to keep most flow in the main navigation channel. In 2008-2009, the dikes were notched to allow more fl...
