In boreal and sub-boreal mixed-species forests, interactions between coniferous and deciduous trees entail competition for limiting resources, such as light, water and nutrients. However, under some conditions the presence of multiple species is hypothesized to facilitate tree growth. My research aims to improve our understanding of the conditions under which competition or facilitation will occur, and what the concomitant impacts on long-term forest dynamics, the resilience of forests to disturbances, and the provision of forest ecosystem services, such as timber production, carbon storage and biodiversity will be. In particular, I will focus on testing how interactions between species are projected to change under novel future climate conditions.

在北方和亚北方混种森林中，针叶树和落叶树之间的相互作用导致竞争有限的资源，如光、水和养分。然而，在某些条件下，假设存在多个物种，以促进树木的生长。我的研究旨在提高我们对竞争或促进将发生的条件的理解，以及对长期森林动态，森林对干扰的恢复力以及森林生态系统服务的提供（如木材生产，碳储存和生物多样性）的伴随影响。特别是，我将专注于测试物种之间的相互作用是如何预测在未来新的气候条件下发生变化的。
