dendroecology and dendroclimatology

北方森林是加拿大的重要资源，也是调节气候的重要碳储存。因此，描述和预测北方地区的气候变率以及研究和预测对植被的相关影响至关重要。分析气候和北方森林之间的联系需要跨越长时间的可靠数据和对北方树木功能的详细了解。在可能的数据来源中，树木年轮年表是生态档案，可以分析几个世纪和几千年来的气候变化和森林进程。拟议的CRC将解决目前的知识差距，基于树木年轮的生态和气候学研究的北方森林：（1）利用很少使用的树木年轮性状，（2）增加经典的年度分辨率的树木年轮为基础的重建，（3）考虑树木的生理功能的分析。将建立一个最先进的木材定量解剖和生理生态建模实验室，吸引优秀的HQP并加强国际合作。树木的功能将在过去两千年的关键时期进行分析：中世纪气候异常，大型火山爆发，火灾前后。加拿大北部地区的森林生长和气候重建及预测将得到改善。

The boreal forest represents an essential resource for Canada and a vital carbon stock for the regulation of the climate. It is thus crucial to characterize and anticipate the climate variability in the boreal region and to study and predict the associated impacts on vegetation. Analyzing the links between climate and the boreal forest requires robust data spanning long time periods and a detailed understanding of the functioning of boreal trees. Among the possible data sources, tree-ring chronologies are ecological archives that allow analysis of climate variability and forest processes over centuries and millennia. The proposed CRC will address current knowledge gaps in tree-ring-based ecological and climatological studies for the boreal forest by: (1) exploiting rarely used tree-ring traits, (2) increasing the classical annual resolution of tree-ring-based reconstructions, and (3) considering tree physiological functioning in the analyses. A state-of-the-art laboratory for quantitative wood anatomy and ecophysiological modeling will be developed, attracting talented HQP and enhancing international collaborations. The functioning of trees will be analyzed for key periods of the last two millennia: the medieval climatic anomaly, following large volcanic eruptions, pre and post fires. Forest growth and climate reconstructions and projections for the Canadian boreal region will be improved.
