98-16493 Fulton 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.

98-16493富尔顿森林生态学家试图通过发展空间显式模拟模型来理解森林动态，这些模型描述了个体层面的相互作用。其中一种模式被称为SORTIE。SORTIE模型是相对较新的，尽管验证有限，但受到社区生态学家的高度重视。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称为SORTIE的森林动力学模拟模型。这个项目的优势之一是将该模型应用于一个与开发该模型时完全不同的森林群落。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价SORTIE在预测森林结构和动态的若干要素方面的表现来评估对森林动力学理论的遮荫容忍是否足够。
