Grazing intensity enhances spatial aggregation of dominant species in a desert steppe [PDF]

Ecology and Evolution, 2019
AbstractUnderstanding how grazing activity drives plant community structure or the distribution of specific species in a community remains a major challenge in community ecology. The patchiness or spatial aggregation of specific species can be quantified by analyzing their relative coordinates in the community.

Desert Dust and Health: A Central Asian Review and Steppe Case Study [PDF]

International Journal of Environmental Research and Public Health, 2017
In Asian deserts environmental and anthropomorphic dust is a significant health risk to rural populations. Natural sources in dry landscapes are exacerbated by human activities that increase the vulnerability to dust and dust-borne disease vectors. Today in Central and Inner Asian drylands, agriculture, mining, and rapid development contribute to dust ...

Species richness is regulated by shallow soil moisture under variable precipitation

Global Ecology and Conservation
Context: Climate change exacerbates global precipitation imbalances, with potential impacts on plant diversity in desert steppe ecosystems. Compared with meadow and typical steppes, desert steppe could be more sensitive to changing precipitation. However,
