Scientists reveal mystery of species coexistence in subtropical forests

BEIJING, Oct. 7 -- Chinese scientists have discovered the mechanism regulating the coexistence of species in subtropical forests, providing a reference for ecosystem restoration in these areas.

The research was led by the Institute of Botany under the Chinese Academy of Sciences. Researchers have spent more than 10 years monitoring 100 species and 25,000 woody plant seedlings in a 24-hectare experimental zone in Zhejiang Province on east China's seaboard. They collected soil around the roots of 322 trees from 34 species and sequenced the DNA of fungi from the samples.

Results revealed the role of different functional soil fungi in driving the biodiversity of subtropical forests. The research has uncovered for the first time that the trees' intraspecific interactions are determined by both harmful pathogenic fungi and beneficial mycorrhizal fungi, offering a new model of tree diversity analysis.

Published in the journal Science, the research will help support China's efforts in protecting and restoring biodiversity in subtropical forests.
