Variation in carbon isotope discrimination in Cleistogenes squarrosa (Trin.) Keng: patterns and drivers at tiller, local, catchment, and regional scales
C4 species 13C discrimination grazing Inner Mongolian steppe leaf nitrogen content precipitation
2015/2/4
Understanding the patterns and drivers of carbon isotope discrimination in C4 species is critical for predicting the effects of global change on C3/C4 ratio of plant community and consequently on ecos...
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...
Can plant lit ter af fect net prima r y production of a typical stepp e in Inner Mongolia?
Growing degree-days Leymus chin ensis Litter addition Litter removal Soil moisture Stipa grandis
2015/2/4
Question: Litter (dead leaves or stems) affects production by conserving soil moisture. However, that role is not clear for grasslands where most precipitation falls during the growing season when the...

Grassland Dryland Sheep grazing Spatial homogeneity Nitrogen Geostatistics
2015/2/4
Spatial heterogeneities of vegetation and soil can strongly affect ecological functions of ecosystems, particularly for arid and semi-arid ecosystems where vegetation has a patchy distribution and liv...
Changes in the abundance of C3/C4 species of Inner Mongolia grassland: evidence from isotopic composition of soil and vegetation
d13C carbon isotope discrimination crossover temperature geostatistics precipitation semivariogram soil organic carbon Suess effect wool
2015/2/4
Global warming, increasing CO2 concentration, and environmental disturbances affect grassland communities throughout the world. Here, we report on variations in the C3/C4 pattern of Inner Mongolian gr...
Large regional-scale variation in C3/C4 distribution pattern of Inner Mongolia steppe is revealed by grazer wool carbon isotope composition
Large regional-scale variation C3/C4 distribution pattern Inner Mongolia steppe grazer wool carbon isotope composition
2015/2/4
This work explored the spatial variation of C3/C4 distribution in the Inner Mongolia, P. R. China, steppe by geostatistical analysis of carbon isotope data of vegetation and sheep wool. Standing commu...
Short-t erm responses of a Stipa grandis/Leymus chinensis community to frequent defoliation in the semi-arid grasslands of Inner Mongolia, China
Grassland degradation Semi-arid Inner Mongolia Defoliation Productivity
2015/2/4
Grassland degradation due to over-grazing causes severe ecological and economical problems in the semi-arid grasslands of Inner Mongolia, PR China. The development of sustainable management systems is...
A comparison of two models with Landsat data for estimating above ground grassland biomass in Inner Mongolia, China
