Researchers reveal the law of cave biological relocation in East Asia Asia

Xinhua News Agency, Beijing, August 16th (Reporter Zhang Quan) Chinese researchers revealed the relocation law of cave creatures in the East Asian subtropical region and analyzed the main factors that affect the migration of the surface creatures into caves. The study has enhanced the level of cognition of the history of the diversity of cave biological diversity, which is of great significance for the protection of the diversity of ground and underground biological diversity.

The research was completed by Wang Wei, a researcher at the Institute of Botanical Research of the Chinese Academy of Sciences, and published the relevant results in the international academic journal "Institute of the American Academy of Sciences" online.

"The global cave system has bred about 50,000 kinds of caves living. The inside of the cave is usually weak, the temperature is constant, the humidity is high, and the nutrition is barren. It is a very unique ecosystem. Large. In -depth research on cave creatures is of great significance to protect biological diversity. "Wang Wei introduced that East Asia has a wealth of cave systems and bred many unique creatures. It is a hot area for biodiversity research.

Scientific researchers use the unique creatures of the East Asia-Asian tropical cave as the research object. It is found that 88%of the cave creature movement occurred after the junction of the Sino-Singapore-China Sino-Singapore (about 23 million years ago). East Asian tropical evergreen broad -leaved forests originated from the surface. Researchers further analyzed that the evolution of geology, climate and subtropical evergreen broad -leaved forests in the region jointly drove the movement of cave creatures.

In addition, the study also found an incident that returned from the cave life 9 times: 1 plant, 5 animals, and 3 times. "This shows that the cave is not only a shelter for forest species, but also a resource library for the restoration of the forest ecosystem." Wang Wei said.
