In a study published in the journal Science, researchers from the Xishuangbanna Tropical Botanical Garden of the Chinese Academy of Sciences showed that the alpine flora of the Hengduan Mountains has continuously existed far longer than any other alpine flora on the Earth.
The research team analyzed time-calibrated phylogenies of nearly 4,000 species from 18 flowering plant groups.
Research shows that the alpine bioregion of the Hengduan Mountains in southwest China was formed about 30 million years ago.
Alpine species are vulnerable to global warming. To understand how alpine biotas respond to historical environmental change may improve our ability to predict and mitigate ecological threats. (CGTN)
Researchers from the Xishuangbanna Tropical Botanical Garden of the Chinese Academy of Sciences showed that the alpine flora of the Hengduan Mountains has continuously existed far longer than any other alpine flora on Earth. They also illustrated how modern biotas have been shaped by past geological and climatic events.
Submerged vegetation recovery is the key technology for ecological restoration of the West Lake, Hangzhou, China. However, serious problems such as sediment phosphorus stress and colonization difficulty still bedevil this lake. The research group led by Prof. WU Zhenbin from Institute of Hydrobiology of Chinese Academy of Sciences chose the red mud-based porous ceramic filter material (PCFM) and new modified bentonite particle screened through a variety of modified methods as absorbent material.
