BEIJING, Aug 17 (XINHUA\/APP): Chinese researchers have revealed the law of biotic colonization of cave organisms in subtropical East Asia, according to the Institute of Botany under the Chinese Academy of Sciences.<\/p>\n
Caves are home to unique and fragile biotas with high levels of endemism. Subtropical East Asia holds the world’s largest karst land-form with numerous ancient caves, which harbor a high diversity of cave-dwelling organisms and are regarded as a biodiversity hotspot, said Wang Wei, head of the research team.<\/p>\n
Through the analysis of phylogenetic, differentiation time and bio-geography on 28 plants, animals and fungi in East Asian subtropical caves, they discovered that 88 percent of cave colonization events occurred after the Oligocene-Miocene boundary, and organisms from the surrounding forest were a major source for subtropical East Asian cave biodiversity.<\/p>\n
Researchers have also found nine instances where organisms returned to the surface from cave biotas. “This phenomenon indicates that caves are not only a sanctuary for forest species, but also a resource pool for forest ecosystem restoration,” Wang said. The study was published in the journal The Proceedings of the National Academy of Sciences.<\/p>\n","protected":false},"excerpt":{"rendered":"
