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

该奖项旨在支持一项研究，该研究将确定热带阔叶木树种的年轮是否代表年生长轮。将进行实地工作，从有简短仪器记录可供校准的地区收集羊膜草样本。将使用同位素分析以及可视化和计算机辅助的交叉测年方法来确定该物种的生长历史。这项拟议研究的更广泛影响是，如果确定生长轮是一年生的，将有一个泛热带分类群可用于热带陆地环境的树状年代学和气候学研究。

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.
