Outline of Final Research Achievements

This project had three subjects. (1) The mechanisms underlying the tradeoff between leaf photosynthetic efficiency and leaf longevity, (2) the cost-and-benefit related to tree height, and (3) eco-evolutionary study on phenotypic diversity of Metrosideros polymorpha. The following achievements were made: (1) we made a novel data compilation incorporating rarely considered traits such as cell walls, nitrogen allocation and mesophyll CO2 diffusion, and clarified the general mechanisms underlying the tradeoff between leaf photosynthetic efficiency and leaf longevity. (2) We have made a new concept to understand how light competition drives forest structure. (3) We established 52 study sites over the island of Hawaii and did intensive trait measurements for more than 2000 individuals to get insights how phenotypic diversity has been formed and maintained over the island.
