Multicentury perspectives on forest dynamics and climatic change in Canada

全球气候变化是对生态系统的重要威胁。了解气候变化和变化对生态系统进程的影响有助于为减轻气候变化的不利经济和生态影响提供工具。同样，了解生态系统如何应对气候变化应该有助于洞察构建社区的过程。概括地说，拟议研究的目的是评估环境变异性和变化如何影响森林结构和构成。具体地说，我的目标是回答以下三个研究问题：

Global climatic change represents an important threat to ecosystems. Understanding the effects of climatic variability and change on ecosystem processes could help provide tools for mitigating the adverse economic and ecological effects of climatic change. Similarly, understanding how ecosystems respond to climatic change should provide insights into the processes that structure communities. Broadly stated, the purpose of the proposed research is to assess how environmental variability and change have affected forest structure and composition. Specifically, I aim to answer the three following research questions:
