Quantitative assessment of Sabah endemic species using species distribution modelling

Sabah is one of the states in Malaysia that are rich in forests together with Sarawak and other state in Malaysia. Dipterocarps are one of the main forest that is available in Sabah since this type of tree are found easily anywhere in Sabah's forest. The dipterocarps tree was the source of timb...
