Prospective and Retrospective Studies on Plant Evolutionary Response to Climate Change

加拿大上一次气候变暖是在更新世之后，持续了几千年。当物种从南方的冰川避难所出现时，它们经历了许多代的进化，重新适应北方纬度。目前的气候变化是几十年来发生的，一些物种只有通过对条件突变的快速进化反应才能生存下来。至关重要的是，有关保护生物多样性和生态系统服务的实际决定应参考有关进化潜力的基本证据。需要测试案例来探索遗传方差对适应性进化的限制，以及保护措施对重温这些限制的效力。我们将探索与进化极限相关的3个主题，为5名研究生和30多名本科生提供培训机会- HQP为将做出这些决定的一代。

Canada’s last episode of climate warming, following the Pleistocene, played out across millennia. Species had many generations for evolutionary re-adjustment to northern latitudes as they emerged from glacial refugia in the south. Current climate change is occurring over decades, and some species will persist only through rapid evolutionary response to abrupt changes in conditions. It is crucial that practical decisions on preservation of biodiversity and ecosystem services be informed by basic evidence on evolutionary potential. Test cases exploring limits on adaptive evolution set by genetic variance, and efficacy of conservation measures to relive those limits, are needed. We will explore 3 themes related to evolutionary limits, giving training opportunities for 5 graduate students and over 30 undergraduates - HQP for the generation that will make those decisions.
