Anthropogenic acid deposition–induced soil acidification is one of the major threats to biodiversity, ecosystem functioning and services. Few studies, however, have explored in detail how above-ground...
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...
Changes in carbon and nitrogen of Chernozem soil along a cultivation chronosequence in a semi-arid grassland
Changes in carbon nitrogen of Chernozem soil cultivation chronosequence semi-arid grassland
2015/2/4
Changes in the carbon (C) stock of grassland soil in response to land use change will increase atmospheric CO2, and consequently affect the climate. In this study we investigated the effects of land u...
