| Outline of Final Research Achievements |
Specimens of plot trees, established in small protected forests called "plau" (meaning 'island') in Borneo, Malaysia, were collected for species identification using DNA barcoding (rbcL + matK) and to assess species richness and phylogenetic diversity. A total of 1259 plot trees were checked the identification, and a diversity assessment was conducted in the Limau area (3 plots, 542 individuals), where specimens could be imported. The species richness was recorded as 82, 80, and 77, while the phylogenetic diversity was calculated as 2913, 3058, and 2741 (in million years), respectively. Although these findings are preliminary, a comparison of species richness before and after species identification based on the specimens collected in this study, indicated no significant changes. However, there were differences of approximately 10% at the family level, 30% at the genus level, and 60% at the species level.
