Forest Entomology

近几十年来的气候变化导致许多物种的分布范围发生了变化。物种范围的扩大是气候变化的短期影响，可能对新殖民生态系统的动态产生重大影响。在北美，一个备受关注的物种扩张是山松甲虫。山松甲虫是加拿大松林中最具破坏性的害虫，其向东扩散到北方针叶松林的问题引起了人们的高度关注。我的项目重点研究了短叶松林的本地病虫害，并探讨了它们在改变树木对山松甲虫易感性中的潜在作用。我将评估这些生物与山松甲虫的相互作用在多大程度上影响山松甲虫与杰克松在杰克松林中相互作用的结果。我将生成山松甲虫入侵成功的预测，并制定先发制人的管理策略，以减轻山松甲虫对杰克松的可能影响。

Climate change in recent decades has led to shifts in the ranges of many species. Species range expansions are a short-run effect of climate change that could have large impacts on the dynamics of newly colonized ecosystems. In North America, one species expansion of great concern is that of the mountain pine beetle. The mountain pine beetle is the most destructive insect pest in Canadian pine forests and now there is great concern about its eastward spread to the jack pine boreal forest. My program focuses on native insects and diseases of jack pine forest and explores their potential roles in altering tree susceptibility to the mountain pine beetle. I will evaluate the extent to which interactions of these organisms with mountain pine beetle can influence the outcome of mountain pine beetle-jack pine interactions in jack pine forest. I will generate predictions of the invasion success of the mountain pine beetle, and develop pre-emptive management strategies to mitigate probable impacts of mountain pine beetle on jack pine.
