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.

该奖项旨在支持研究，该研究将确定热带硬木物种中的树环Hymenaea Curbaril代表年增长环。将进行场地工作，以收集从可用于校准的短工具记录的地方收集Hymenaea Curbaril的样本。 同位素分析以及视觉和计算机辅助方法的交叉约会方法将用于确定该物种的生长历史。这项拟议的研究的更广泛的影响是，如果确定生长环是年度的，则可以用于热带陆地环境的树突年代学和气候研究。
