Collaborative Research: Testing Shade Tolerance as a Central Element of Forest Dynamics Theory Using a Forest Dynamics Simulator & Long-Term High-Resolution Demographic Data

Harcombe森林生态学家试图通过开发描述个体水平相互作用的空间显式模拟模型来了解森林动态。其中一种模式就是所谓的出击。这种突击模型是相对较新的，受到了社区生态学家的高度评价，尽管验证有限。这项拟议的调查将使用树木人口统计学的长期数据集来参数化和验证名为TOTTY的森林动态模拟模型。该项目的一个优点是将该模型应用于一个与其开发时所针对的森林社区截然不同的森林社区。调查将结合实地研究、长期地块数据分析和模拟。该项目的一个重要重点是通过评估出击在预测森林结构和动态的几个要素方面的表现，来评估遮荫耐受性对森林动态理论的充分性。

9726467Harcombe Forest ecologists attempt to understand forest dynamics through the development of spatially-explicit simulation models that describe individual-level interactions. One such model is known as SORTIE. The SORTIE model is relatively recent and fairly highly regarded by community ecologists, despite limited validation. This proposed investigation will use a long-term data set on tree demography to parameterize and validate a forest dynamics simulation model known as SORTIE. One strength of this project is the application of the model to a forest community quite different from that for which it was developed. The investigation will combine field studies, analysis of long-term plot data and simulations. An important focus of the project is to assess the sufficiency of shade tolerance to the theory of forest dynamics by evaluating the performance of SORTIE in predicting several elements of forest structure and dynamics.
