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。物种分布范围的扩大是气候变化的短期效应，可能对新殖民生态系统的动态产生重大影响。在北美，一个物种的扩张非常令人担忧的是山松甲虫。山松甲虫是加拿大松林中最具破坏性的害虫，现在人们非常担心它向东蔓延到北美短叶松北方森林。我的计划侧重于本地昆虫和杰克松森林疾病，并探讨他们在改变树的易感性山松甲虫的潜在作用。我将评估这些生物与山松甲虫的相互作用在多大程度上可以影响山松甲虫杰克松在杰克松森林相互作用的结果。我将预测山松甲虫的入侵成功率，并制定先发制人的管理策略，以减轻山松甲虫对短叶松的可能影响。

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.
