This project involves an integrative synthesis of 52 studies published by Dr. Monson over the past 14 years on how a subalpine forest exchanges carbon dioxide and water with the atmosphere. The project will enhance the utility of this body of work, improving its potential to inform stakeholders and land managers about the causes of several environmental challenges that have emerged in the Western US. These include an epidemic pine beetle outbreak, mass tree die-off due to persistent drought, high frequencies of wildfires, and uncertainty in the contribution of forests to regional carbon budgets. The investigator plans to: extract new, longer-term insights from a 14-year data set of forest carbon and water fluxes; use the longer-term insights to re-assess conclusions from the previously published papers; and disseminate the synthesis to those attempting to understand and manage forest ecosystems of the Western US. The synthesis will be conducted using an advanced computer modeling procedure known as Artificial Neural Network (ANN) analysis. The ANN analysis will be conducted in a manner that elucidates how changes in weather and climate affect the ability of the forest to exchange carbon and water with the atmosphere. This project will support the work of a Graduate Research Assistant (GRA) to implement the ANN analysis. The results will be disseminated to the through: (1) an article intended for professional ecologists; (2) an invited Spotlight Article intended for foresters and land managers; (3) a book chapter intended for beginning graduate students; and (4) a chapter intended for college undergraduate students in a Wiki and hardbound book.

该项目涉及蒙森博士在过去14年中发表的52项研究的综合性综合，这些研究涉及亚高山森林如何与大气交换二氧化碳和水。 该项目将提高这项工作的效用，提高其向利益相关者和土地管理者通报美国西部出现的几个环境挑战的原因的潜力。这些因素包括流行性松甲虫爆发、持续干旱导致的大规模树木死亡、野火频发以及森林对区域碳预算贡献的不确定性。研究者计划：从14年的森林碳和水通量数据集中提取新的，长期的见解;使用长期的见解重新评估以前发表的论文的结论;并将综合传播给那些试图了解和管理美国西部森林生态系统的人。 将使用称为人工神经网络（ANN）分析的先进计算机建模程序进行综合。人工神经网络分析将以阐明天气和气候变化如何影响森林与大气交换碳和水的能力的方式进行。该项目将支持研究生研究助理（GRA）的工作，以实现人工神经网络分析。结果将通过以下方式传播：（1）专为专业生态学家撰写的文章;（2）专为林业人员和土地管理人员撰写的特邀聚光灯文章;（3）专为开始研究生撰写的书籍章节;以及（4）专为大学本科生撰写的Wiki和精装书章节。
