Grazing influences Stipa breviflora seed germination in desert grasslands of the Inner Mongolia Plateau
Seed germination plays an important role in determining the composition and regeneration of plant populations (Stipa breviflora). However, the influencing factors and strategies employed for seed germination in desert grasslands under grazing remain unknown. Therefore, in this study, the reproductive allocation, seed density, seed properties, and corresponding seed germination rates of S. brevi...
متن کاملSheep Wool δ13C Reveals No Effect of Grazing on the C3/C4 Ratio of Vegetation in the Inner Mongolia–Mongolia Border Region Grasslands
We tested whether the abundance of C(4) vegetation in grasslands of the Mongolian plateau is influenced by grazing conditions. The analysis exploited the politically originated contrast that exists between Mongolia (low stocking rate, transhumant system) and the district of Inner Mongolia, China (high stocking rate, sedentary system). We estimated the proportion of C(4) carbon (P(C4)) in grazed...
متن کاملGrassland desertification by grazing and the resulting micrometeorological changes in Inner Mongolia
Overgrazing is one of the most primary causes of desertification in semi-arid zones of China. From 1992 to 1994 we conducted a grazing experiment in Naiman (lat. 42◦58′N, long. 120◦43′E, 345 m asl), Inner Mongolia, China to elucidate desertification mechanisms. Our experimental field, which was covered with some short grasses, legumes and forbs, included four plots where grazing sheep numbers d...
متن کاملIncrease in ammonia volatilization from soil in response to N deposition in Inner Mongolia grasslands
Ammonia (NH3) is an important component of the nitrogen (N) cycle in terrestrial ecosystems and is a significant atmospheric pollutant. Results from studies of ammonia emissions from semi-arid grasslands have been infrequently reported although these emissions may be increasing rapidly with a subsequent increase in atmospheric N deposition. Moreover, whether N deposition regimes (fertilization ...
متن کاملDynamics of Soil Organic Carbon and Aggregate Stability with Grazing Exclusion in the Inner Mongolian Grasslands.
Grazing exclusion (GE) has been deemed as an important approach to enhance the soil carbon storage of semiarid grasslands in China; however, it remains unclear how different organic carbon (OC) components in soils vary with the duration of GE. Here, we observed the changing trends of different OC components in soils with increased GE duration in five grassland succession series plots, ranging f...
