Grazing alters ecosystem functioning and C:N:P stoichiometry of grasslands along a regional precipitation gradient
China–Mongolia transect N and P co-limitation N cycling plant and soil C N and P pools plant functional group composition primary production stoichiometry the Eurasian steppe
2015/2/4
The Eurasian steppe has long been subject to grazing by domestic ungulates at high levels, resulting in widespread deterioration of biodiversity and ecosystem services. While abundant evidence demonst...
C4 abundance in an Inner Mongolia grassland system is driven by temperature–moisture interaction, not grazing pressure
C4 abundance Inner Mongolia grassland system temperature–moisture interaction not grazing pressure
2015/2/4
Global warming and CO2 rise is expected to change the balance of C3 and C4 plants in grassland vegetation, but disturbance,including grazing, could also affect C3/C4 community structure. We used a six...
Seasonally dependent impacts of grazing on soil nitrogen mineralization and linkages to ecosystem functioning in Inner Mongolia grassland
Typical steppe Grazing intensity Season Soil inorganic N pools Net N mineralization Soil temperature and moisture BiomassN content Nitrogen use efficiency
2015/2/4
Previous studies have suggested grazing may alter nitrogen (N) cycling of grasslands by accelerating or decelerating soil net N mineralization. The important mechanisms controlling these fluxes remain...
Differential responses of plant functional trait to grazing between two contrasting dominant C3 and C4 species in a typical steppe of Inner Mongolia, China
plant functional trait grazing between two dominant C3 and C4 species typical steppe of Inner Mongolia China
2015/2/4
Plant functional traits have been widely used to study the linkage between environmental drivers, trade-offs among different functions within a plant, and ecosystem structure and functioning. Here, th...
Plant responses following grazing removal at different stocking rates in an Inner Mongolia grassland ecosystem
Grazing removal Ecosystem stability. Compensatory effect Precipitation variation Grassland management Grassland restoration
2015/2/4
Grazing removal is widely used in grassland management. Plant responses following grazing removal at different organizational levels, however, are not well understood. We examined plant responses at d...
