Distribution and Conservation of Ephedra rhytidosperma [PDF]

Ecology and Evolution
With global warming and increasingly intensified human activities, numerous species are on the verge of extinction, ca. 28% of living species are threatened globally, although conservation of endangered species has received worldwide attention.

Patterns and Driving Mechanisms of β-Diversity in Mountain Plant Communities of Arid Regions. [PDF]

Ecol Evol
We analyzed taxonomic and phylogenetic β‐diversity patterns in plant communities along the northern slope of the central Kunlun Mountains in arid northwestern China. Species turnover dominated β‐diversity, with climatic distance—particularly temperature—being key drivers.

Integrating habitat suitability, phytochemical quality, and landscape stability to identify conservation priorities for Arnebia guttata Bunge under climate change in East Asia [PDF]

Frontiers in Plant Science
Arnebia guttata Bunge is a threatened medicinal plant predominantly distributed in arid and semi-arid regions of China and Mongolia. Increasing medicinal demand and ongoing climate change highlight the need for an integrated evaluation of its habitat ...

Late Quaternary faulting and paleoearthquakes along the northern section of the Bayanhaote fault and their implications for regional seismotectonics

Frontiers in Earth Science, 2022
Analysis of the late Quaternary activity and paleoseismicity of the Bayanhaote fault is critical because it is part of the frontier of the propagating Tibetan Plateau and the boundary between the Alxa and Ordos blocks, and the development of a regional ...

Chemical composition of soil organic carbon and aggregate stability along an elevation gradient in Helan Mountains, northwest China

Ecological Indicators, 2021
Exploring the composition of soil organic carbon (SOC) and aggregate stability over a range of elevations is essential to evaluate the stability of SOC and the conversion of carbon source or sink of mountain ecosystems.

Inferring landscape factors driving microgeographic genetic structure of large-sized mountain ungulates: A case of Alashan red deer (Cervus elaphus alxaicus)

Global Ecology and Conservation, 2023
Gene flow is crucial for maintaining population genetic diversity and increasing the adaptive potential of species. Therefore, identifying factors affecting gene flow is important for conservation planning, especially for threatened mammals in complex ...
