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

生态扰动通过重新设置植物群落和动物群落聚集的舞台，在群落和生态系统生态学中发挥着重要作用。本研究的目的是研究不列颠哥伦比亚省(BC)北部小松林群落结构在连续受到多种生态干扰时的近期轨迹，这种情况在生态学文献中称为复合干扰。生态复原力理论表明，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的背景下。导致这种变化的机制与生长和繁殖的物种间差异有关。植被火灾和昆虫暴发是在最近和遥远的过去对整个加拿大的森林结构和功能做出贡献的自然干扰，但在公元前，最近的山松甲虫(MPB)疫情是一种前所未有的干扰事件，使大片松林容易受到后续火灾和/或森林采伐的复合干扰。

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.
