| Research Abstract |
This study aims to clarify influence of leaf phenology on water cycle in seasonal tropical evergreen forests. Cambodian lowland dry evergreen forests marked heterogeneous leaf-exchange phenology in space and in time. Peak of leaf exchange was at the early dry season for tall dipterocarp, while at the late dry season for understory tree species. We measured intact leaf stomata conductance of emergent dipterocarp trees. Leaf-expanding Dipterocarpus costatus displayed high transpiration potential. The disappearance of the emergent Dipterocarp possibly alters water cycle, in which transpiration, i.e., pumping up groundwater into air, at the mid dry season would decrease drastically.
