| Outline of Final Research Achievements |
We report the dynamics of a magrove forest at Manko wetland. Based on the structural and physiological properties , we simulated forest dynamics for 50 years and compared these results to field data sets. In general, the ratio of the relative growth rate (RGR) to the relative mortality rate (RMR) is around 1.5 in the full-self-thinning phase. On the basis of the simulation results, we hypothesize that the RGR/RMR in the stands is greater than 1.5 in the pre-full-self-thinning phase from 0-6 years, is 1.5 in the full-self thinning phase from 7-27 years, and fluctuates in the post-full-self-thinning phase after 27 years.
We developed a new method to directly measure whole-plant respiration within a 100000000000 fold range of individual mass. Using results of about 600 individuals, we statistically rejected all simple-power functions. Instead, metabolic scaling can be better described statistically with a mixed-power function.
