Global environmental change is causing rapid, often irreversible shifts in the structure and functioning of ecosystems. Understanding the factors that make ecosystems resilient or susceptible to changes in climate and disturbance regimes is critical to efforts to anticipate the impacts of global environmental change. Over the next five years, I will continue to advance my long-term goal of developing a framework to predict changes in northern vegetation and permafrost. To accomplish this, the short-term objectives of my research are to identify the determinants of 1) ecological resistance and 2) ecological recovery. Over the next five years, 4Phd, 2MSc, and 4BSc students will use remote sensing, spatial models, and field studies to isolate the biophysical controls of resistance and recovery in Arctic ecosystems. These projects will advance our understanding of the factors shaping ecological resilience, yield maps of vegetation and permafrost change that inform regional decision making, and contribute to the training of the next generation of environmental scientists.

全球环境变化正在导致生态系统的结构和功能发生迅速的、往往是不可逆转的变化。了解使生态系统对气候和干扰制度的变化具有复原力或易受影响的因素，对于预测全球环境变化的影响至关重要。在接下来的五年里，我将继续推进我的长期目标，即开发一个框架来预测北部植被和永久冻土的变化。要做到这一点，我的研究的短期目标是确定1)生态阻力和2)生态恢复的决定因素。在接下来的五年里，4Phd、2MSc和4BSC的学生将使用遥感、空间模型和实地研究来分离北极生态系统中阻力和恢复的生物物理控制。这些项目将促进我们对影响生态复原力的因素的理解，以及为区域决策提供信息的植被和永久冻土变化的产量图，并有助于培训下一代环境科学家。
