Outline of Final Research Achievements

In order to clarify the current situation of biodiversity in New Caledonia, we carried out conservation genomics analysis for semi-endemic genus Oxera (Lamiaceae) which consists of ca. 30 species with distinct traits in their morphology and ecology. By analyzing transcriptomes obtained from RNA-seq, we inferred several candidate loci that may be involved in speciation and environmental adaptation. In order to construct effective conservation measures, phylogeny of species, genetic differentiation between intraspecies populations, effective population sizes, demographic histories were inferred based on constructed genomic information for exhaustively collected samples of Oxera species and populations.
