Research reveals decreasing genetic connectivity in endangered tree Magnolia patungensis in fragmented forests

Endemic to the mountainous region of East Sichuan, West Hubei and its neighboring areas, Magnolia patungensis Hu is endangered due to overharvesting, habitat degradation and fragmentation. The current endangered status of M. patungensis makes its genetic variation and population connectivity a concern. However, previous studies focused on evaluating the genetic diversity of M. patungensis, the effects of artificial destruction/fragmentation on population connectivity of M. patungensis were not investigated.
