The influence of himalayan-crossing mountain lift on the evolution of the distribution pattern of alpine eucalyptus plants.

Since the late New Generation, with the rise of the Qinghai-Tibet Plateau, the Himalaya-Cross Mountain has experienced complex geological evolution, forming a complex and diverse landscape and climatic environment, providing abundant and diverse living space for plant groups with different ecological needs, making the region one of the global biodiversity hotspots.
environment and its biological evolution are hot topics in geosciences and life sciences, and many scientific and technological personnel have done a lot of research in this field for a long time.
To explore the relationship between the geographical distribution pattern of plant evolution in this area and the elevation of the plateau, Meng Honghu, a researcher at the Xishuangbana Tropical Botanical Garden of the Chinese Academy of Sciences, under the guidance of researcher Zhou Zhekun, carried out a large-scale field survey and sampling of alpine shoals distributed in the Himalayas, the Transverse Mountains, the Southwest Region, central China and Taiwan.
conducted genealogical geography studies from 56 natural habitats collected, analyzed chloroplast genes and nSSR genotypes, and combined species distribution models with relevant paleoencological evidence and geological data from the Himalayan-Crossing Mountains.
The main points of view derived from the study are as follows: (1) the adaptation of alpine shoals to high-cold environments ("Warm-Cold colonization") is proposed to explain the reasons for the formation of the geographical distribution pattern of alpine ferns, i.e., the adaptation to the environmental effects associated with the rise of himalaya-crossing mountains.
In the process of plateau ascension, the alpine moth gradually adapted to the environment of gradually cooling after the elevation of the region, and gradually evolved from a companion species to an advantageous species, and in the course of evolution, the last ice age had less impact on the survival of the group and the change of distribution area.
(2) From the difference time of the alpine eucalyptus genealogy to the Himalayan-Crossing Mountain ascent, although the study can not define the time when the region began to rise, but from the high altitude and low-altitude areas of the alpine eucalyptus genetic lineage differentiation that the Himalayan-Crossing Mountain in the late middle to the upper world has a continuous rise process, from a biological point of view for the geological evolution of the region provides evidence.
the study was published online in Molecular Ecology under the title "Warm-Cold Colonization: Response of oaks to uplifts of The Himalaya-Hengduan Mountains."
the study was supported by major projects of the National Natural Science Foundation of China (31590820,31590823) and the Yunnan Joint Fund of the National Natural Science Foundation of China (U1502231).
