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.

加拿大气候变暖的最后一幕发生在更新世之后，持续了数千年。物种从南方的冰川避难所中走出来时，经历了许多世代的进化重新适应北纬。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持续存在。至关重要的是，关于保护生物多样性和生态系统服务的实际决定必须以关于进化潜力的基本证据为依据。需要测试案例，探索由遗传变异设置的适应性进化的限制，以及恢复这些限制的保护措施的有效性。我们将探索3个与进化极限相关的主题，为5名研究生和30多名本科生提供培训机会-HQP为做出这些决定的一代人提供。
