Genetic, plastic and epigenetic sources of variation for climate change responses in conifers

针叶树种群适应新气候条件的能力很重要，因为它们在全球碳循环中发挥着重要作用，在许多生态系统中作为基础物种发挥着生态作用，对资源生产也很重要。考虑到气候变化，我们应该在多大程度上改变森林养护和管理战略，这将取决于人口作出反应的自然能力。我的研究小组将探索从核心和边缘种群的常设变异，对亲本环境的表观遗传反应，通过表型可塑性对新条件的耐受性，以及体细胞突变对常设变异的贡献的适应性反应的潜力。拟议的项目将解决以下问题。

The capacity of conifer populations to adapt to new climatic conditions is important because of their large roles in the global carbon cycle, ecological roles as foundation species in many ecosystems, and importance for resource production. The extent to which we should change forest conservation and management strategies in consideration of climate change will depend on the natural capacity of populations to respond. My research group will explore the potential for adaptive responses from standing variation in core and marginal populations, epigenetic responses to parental environments, tolerance of new conditions through phenotypic plasticity, and contributions to standing variation from somatic mutations. The proposed projects will address the following questions.
