Environmental Variability and Forest Pattern: A Comparison of Eastern and Western Landscapes

小行星9652656 相互作用 在物理站点特征中， 生物过程和人类的影响使我们无法预测生态系统对环境变化的反应。由于这些复杂性，影响评估的相关方法在资源需求所需的时间尺度上可能是无关紧要的。 管理和缓解。 这 研究 将阐明森林对环境约束的反应机制，并将这些反应从林分扩展到景观。 将进行实地研究， 四个对比鲜明的地区：太平洋西北部、内华达州山脉、东北部和东南部。我们将探索这些森林的敏感性，以模拟气候变化，使用林分和植被规模的模型。 将在所有地点使用一个共同的建模框架，以提供一个明确的，结构化的方法来评估不同地点之间的森林反应的差异。这项研究的结果将提供新的网站和区域尺度的见解，对气候变化的瞬态森林响应的环境控制。

9652656 Urban Interactions among physical site features, biological processes, and human influences confound our ability to predict ecosystem response to environmental change. Because of these complications, correlational approaches to impact assessment may be irrelevant at the time scales required for resource management and mitigation. This study will elucidate the mechanisms of forest response to environmental constraints, and scale these responses from stands to landscapes. Field studies will be conducted for four contrasting regions: the Pacific Northwest, the Sierra Nevada, the Northeast, and the Southeast. We will explore the sensitivity of these forests to simulated changes in climate using stand- and landscape-scale models. A common modeling framework will be used across all sites to provide an explicit, structured method for assessing differences in forest response among sites. The results of this study will provide new site- and regional-scale insights into the environmental control of transient forest responses to climatic change.
