Canada is a land of many climates and environments, from temperate forest to tundra and prairie to alpine. Plants are adapted to these environments and, even within a species, populations may be found that are genetically adapted to local environments. Precise adaptation of this sort is essential for productive plant growth in agriculture and forestry but the genetic basis of this process is incompletely known. The long term objective of this program of research is to use recent advances in genomics to determine the genome-wide architecture of plant adaptation. The main focus will be on the black cottonwood trees of British Columbia, which we have shown to exhibit extensive local adaptation to the varied terrain. Knowledge of plant adaptation is important for predicting the effect of climate change on ecosystems and for forest improvement and will facilitate conservation and appropriate use of native Canadian trees.

加拿大是一个拥有多种气候和环境的国家，从温带森林到苔原和草原到高山。植物适应这些环境，甚至在一个物种中，可能会发现种群在遗传上适应当地环境。这种精确的适应对于农业和林业中的生产性植物生长是必不可少的，但这一过程的遗传基础还不完全清楚。这项研究计划的长期目标是利用基因组学的最新进展来确定植物适应的全基因组结构。主要的重点将是在不列颠哥伦比亚省，我们已经证明，表现出广泛的当地适应不同的地形的黑棉白杨树。植物适应知识对于预测气候变化对生态系统的影响和森林改良十分重要，并将促进加拿大本土树木的养护和适当利用。
