Adaptation of Lodgepole pine (Pinus contorta) provenances to extreme climate events

长期的种源试验可以评估树种不同基因型的气候-生长关系。这方面的知识对于减轻气候变化对森林生态系统的影响至关重要。该项目利用了一个独特的机会，在Lodgepole松树（Pinus contorta Dougl）种源试验中，基于破坏性全树分析来研究气候生长关系。大声的。)。通过结合年高度增量、径向生长、年内高分辨率木材密度和碳同位素剖面，该方法将能够全面评估气候变化对碳封存、木材生产和木材特性的影响。它还将使我们能够在气候变化的情况下确定有恢复力和生产力的基因型，以便重新造林。

Long-term provenance trials allow assessing climate-growth relationships of different genotypes of a tree species. This knowledge is crucial in efforts to mitigate impacts of climate change on forest ecosystems. This project is taking advantage of a unique opportunity to study climate growth relations based on destructive whole-tree analysis in provenance trials of Lodgepole pine (Pinus contorta Dougl. ex. Loud.). By combining annual height increment, radial growth, intra-annual high resolution wood density and carbon isotope profiles, this approach will allow for a comprehensive assessment of climate change impacts on carbon sequestration, wood production and wood characteristics. It as well will allow identifying resilient and productive genotypes for reforestation in a changing climate.
