Collaborative Research: Annual Rings in the Tropical Tree Hymenaea Courbaril--Determination by 14C and Climatic Interpretation

该奖项是为了支持研究，将确定是否在热带阔叶树种Hymenaea courbaril树木年轮代表一年的年轮。实地工作将进行，以收集样品的Hymenaea courbaril从当地的短仪器记录可用于校准。 同位素分析和视觉和计算机辅助的交叉年代测定方法将用于确定该物种的生长历史。这项拟议研究的更广泛的影响是，如果年轮被确定为年度，泛热带分类将可用于树木年代学和热带陆地环境的气候学研究。

This award is to support research that will determine whether tree rings in the tropical hardwood species Hymenaea courbaril represent annual growth rings.Field work will be undertaken to collect samples of Hymenaea courbaril from localities where short instrumental records are available for calibration. Isotopic analyses and and visual and computer assisted methods of cross dating will be used to determine the growth history of this species. The broader impacts of this proposed research are that, if the growth rings are determined to be annual, a pan-tropic taxon will be available for dendrochronology and climatologic studies of tropical terrestrial environments.
