Article Synopsis
- The Ogasawara Islands in Japan have a unique ecosystem with many endemic species, including a critically endangered shrub with only four individuals left in nature.
- Current conservation efforts include both in situ (natural habitat) and ex situ (cultivated) methods, but they are hindered by a lack of important data.
- Research conducted on the shrub's genetic diversity found strong genetic variation in both in situ and ex situ populations, suggesting that conservation should focus on enhancing genetic diversity through cross-pollination and introducing unique genotypes into cultivated stock.
Melastoma (Melastomataceae) includes ca. 100 species across tropical to subtropical regions of Asia and Oceania. The Bonin Islands harbor three endemic taxa: M.

However, there is little evidence for higher vulnerability and extinction risk in endangered species based on genomic differences between endangered and non-endangered species. This is true even in the case of functional loci, which are more likely to relate to the fitness of species than neutral loci.

Methods And Results: Using next-generation sequencing, 27 microsatellite markers were identified.
