"Mobile laboratory for the geography of disturbance: Ecosystem disturbances, interactions, and landscape resilience"

生态干扰通过改变植物和动物群落的聚集状态，在群落和生态系统生态学中发挥着重要作用。本研究计划的目的是研究短期轨迹的北方小孢子松林群落结构在不列颠哥伦比亚省（BC），当它暴露于多个生态干扰的连续，在生态文献中称为复合干扰的情况。生态恢复力理论表明，复合干扰有可能将生态系统推向不同的状态，改变生物多样性，特别是在气候变化等额外压力因素的背景下。促成这种变化的机制与生长和繁殖的物种间差异有关。植被火灾和昆虫爆发是自然干扰，在不久的将来和遥远的过去，对加拿大各地的森林结构和功能做出了贡献，但在不列颠哥伦比亚省，最近的山松甲虫（MPB）流行病是一个前所未有的干扰事件，使大片松林容易受到随后的火灾，森林采伐或两者的复合干扰。

Ecological disturbances play a significant role in community and ecosystem ecology by re-setting the stage on which plant and animal communities assemble. The objective of this research program is to study the near-term trajectory of northern lodgepole pine forest community structure in British Columbia (BC) when it is exposed to multiple ecological disturbances in succession, a situation known in the ecological literature as compounded disturbance. Ecological resilience theory suggests that compounded disturbances have the potential to nudge ecosystems into different states with altered biodiversity, especially in the context of additional stressors such as climate change. Mechanisms contributing to this change are associated with inter-species variation in growth and reproduction. Vegetation fires and insect outbreaks are natural disturbances that have contributed to forest structure and function across Canada in the near and distant past, but in BC the recent mountain pine beetle (MPB) epidemic is an unprecedented disturbance event that has left a vast area of pine forest prone to compounded disturbance by subsequent fire, forest harvesting, or both.
