| Outline of Final Research Achievements |
We conducted analyses of conservation genomics on wild and ex situ individuals of critically endangered endemic plant species of the Bonin Islands. Using genomic information from RAD-seq and RNA-seq, genetic diversity, genetic differentiations, spatial genetic structure, intraspecies phylogeny and genes selected during radiative speciation for endangered endemics were inferred. We found species specific genetic traits for each taxon, such that, species without any genetic diversity in both wild and ex situ populations, one with significantly accumulated deteriorated genes and those under processes of speciation containing cryptic species. These findings are useful to achieve appropriate biological conservation activities.
