Grazing alters the biophysical regulation of carbon fluxes in a desert steppe
To determine the role of grazing on CO2 fluxes in a desert steppe, we used paired eddy-covariance systems to measure the net ecosystem exchange (NEE) and microclimate on adjacent pastures of grazed (GS) and ungrazed (FS) steppes on the Mongolian Plateau from 2010 to 2011. The first year was an average precipitation year, while the second year was a dry year. In 2010, there was 91% greater growi...
متن کاملImpact of Grazing on Soil Carbon and Microbial Biomass in Typical Steppe and Desert Steppe of Inner Mongolia
The potential of grazing lands to sequester carbon must be understood to develop effective soil conservation measures and sustain livestock production. Our objective was to evaluate the effects of grazing on soil organic carbon (SOC), total nitrogen (TN), microbial biomass carbon (MBC) in Typical steppe and Desert steppe ecosystems, which are both important grassland resources for animal grazin...
متن کاملLegacy effects from historical grazing enhanced carbon sequestration in a desert steppe
Legacy effects are the ecological inheritances produced by preceding actions, which have been underlined more on agricultural land use, wildfire, invasive and removal species, forest management, and extreme climates in previous research; however, very few studies have shown concern toward the grazing legacy effects on key ecosystem functions such as the carbon cycle. A nested random block desig...
متن کاملHow planting density and grazing intensity affect the above- and below-ground carbon pools in a dryland ecosystem?
Climate change is known as one of the most important environmental challenges. Sequestration of carbon in terrestrial ecosystems is a low-cost option that may be available in the near-term to mitigate increasing atmospheric CO2 concentrations, while providing additional benefits. In this study, we estimated the effects of planting density and grazing intensity on the potential of Atriplex canes...
متن کاملA six-year grazing exclusion changed plant species diversity of a Stipa breviflora desert steppe community, northern China
Excluding grazers is one of most efficient ways to restore degraded grasslands in desert-steppe communities, but may negatively affect the recovery of plant species diversity. However, diversity differences between grazed and fenced grasslands in desert-steppe are poorly known. In a Stipa breviflora desert steppe community in Northern China, we established six plots to examine spatial patterns ...
