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...
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...
