Conservation genetics and potential geographic distribution modeling of Corybas taliensis, a small 'sky Island' orchid species in China.

ABSTRACT:

Background

Corybas taliensis is an endemic species of sky islands in China. Its habitat is fragile and unstable, and it is likely that the species is threatened. However, it is difficult to determine the conservation priority or unit without knowing the genetic background and the overall distribution of this species. In this study, we used double digest restriction-site associated DNA-sequencing (ddRAD-seq) to investigate the conservation genomics of C. taliensis. At the same time, we modeled the extent of suitable habitat for C. taliensis in present and future (2030 and 2090) habitat using the maximum-entropy (MaxEnt) model.

Results

The results suggested that the related C. fanjingshanensis belongs to C. taliensis and should not be considered a separate species. All the sam
