Phenologies of the Tabonuco Forest trees and shrubs

These data are being used to, among other things, (1) determine the seasonality of flowering and fruiting in Tabonuco forest and test hypotheses concerning the causation of seasonality (or lack thereof), (2) test the effect of annual variation in rainfall and other climatic variables on seed and fruit production of individual species, and (3) compare the relative dispersal of species on the Luquillo Forest Dynamics Plot by applying information on the spatial distribution of canopy trees to the data on seed and fruit fall. These data also serve as background information on the flowering and fruiting of individual species.

这些数据主要用于以下研究（及其他相关工作）：（1）确定塔博努科森林（Tabonuco forest）中植物开花与结果的季节性特征，并验证关于季节性成因（或无季节性）的假设；（2）测试降雨量年度变化及其他气候变量对单个物种种子和果实产量的影响；（3）通过将冠层树木的空间分布信息与种子和果实掉落数据相结合，比较卢基约森林动态样地（Luquillo Forest Dynamics Plot）中不同物种的相对扩散能力。此外，这些数据还可作为各物种开花与结果特性的背景参考信息。
