Outline of Final Research Achievements

We explored the mechanisms of origin and maintenance of plant biodiversity on East Asian islands. Specifically, we tested 1) regional diversity anomaly of temperate flora using community phylogenetics, 2) paleoecolgical processes underpinning diversity pattern of Tertiary relict flora, 3) historical processes of plant biodiversity on East Asian islands, 4) hierarchical filtering effects on woody plants communities. Based on these results, we demonstrated the relative importance of macroevolutionary processes relative to geographical constraints and ecological processes involving environmental filters and species interaction on shaping plant biodiversity patterns in time and space.
