| 研究実績の概要 |
Last year, the first year of the three-year project, we established field and laboratory experiments and began collecting phenological and plant performance data. In 2022, the second year of the project, we focused on data gathering both in the field and in the growth chambers. Important elements of this study, i.e. 1) detailed environmental data (light level and temperature) across the growing season, 2) leaf phenology of target species from leaf emergence to leaf senescence and, 3) leaf performance (photosynthetic response to light and temperature variations) and leaf cost (LMA determination) of target plants were monitored during the year. These data will form the basis of the leaf functional parity (LFP) calculations that will begin in the 3rd year of this study. We have also begun a survey of forest dynamic modeling approaches in the literature during 2022 and we have identified a number of potentially useful models and will follow up with trial testing these models for their suitability in incorporating LFP input. The forest dynamic models are intended to process our LFP estimates on plant performance (seasonal) and generate probabilities of survivorship in current understory environment and, most importantly, in a future environment affected by climate change.

2: おおむね順調に進展している
理由
This research is advancing in accordance to schedule. Specifically, in 2022, the first full year of data required for the final analysis were collected from the field and laboratory and we are in the process of completing the second full year of data in 2023.
|
| 今後の研究の推進方策 |
In the third and last year of this project, we will complete the field and laboratory measurements and transition to the analysis of data and to the modeling effort. Towards the end of 2023, we will begin to prepare a publication of our findings and consider the presentation of our results at an ecological conference.
|
| 次年度使用額が生じた理由 |
We budgeted an amount that will cover emergency repairs and contingency purchases that occur during the research year. However, such expenditures were not needed, hence the surplus in the budget. This surplus will be put to use in the next fiscal year for similar contingency expenses, and for additional purchase of supplies and software required to complete our project.
