Heavy grazing reduced the spatial heterogeneity of Artemisia frigida in desert steppe [PDF]
BMC Plant Biology, 2022 Background Grazing disturbance plays an important role in the desert steppe ecosystem in Inner Mongolia, China. Previous studies found that grazing affected the spatial distribution of species in a community, and showed patchiness characteristics of ...

Effect of Precipitation Change on Desert Steppe Aboveground Productivity. [PDF]
Biology (Basel)Precipitation changes have significant impacts on biodiversity and ecosystem productivity. However, the effects of precipitation changes on species diversity have been the focus of most previous studies. Little is known about the contributions of different dimensions of biodiversity (species, functional, and phylogenetic diversity) in linking long-term

Characteristics of dust emission over desert steppe
GeodermaDesert steppe is widely distributed in wind erosion regions, and is also an important potential dust emission source in the regions. Recognition of dust emission characteristics of desert steppe is the foundation for accurate simulation of dust emission ...

The stability of perennial grasses mediates the negative impacts of long-term warming and increasing precipitation on community stability in a desert steppe [PDF]
Frontiers in Plant Science, 2023 BackgroundDesert steppe, as an ecotone between desert and grassland, has few species and is sensitive to climate change. Climate change alters species diversity and the stability of functional groups, which may positively or negatively affect community ...

Impact of Human Activities on Hydrological Drought Evolution in the Xilin River Basin
Atmosphere, 2022 The impact of human activities on the hydrological cycle makes hydrological drought no longer a natural disaster in a strict sense, and influences the stationarity of the hydrologic process. In this context, assessment methods that consider nonstationary
