报告题目：Big, Fast, Ecosystem Changes from Interacting Extreme Disturbance Events in Southwest US Mountain Landscapes: Hotter Droughts, Forest Die-Offs, Insect Outbreaks, Fires & Floods
报告人：Craig D Allen
Craig D. Allen is a research ecologist with the USGS Fort Collins Science Center, and is Station Leader of the New Mexico Landscapes Field Station (formerly the Jemez Mountains Field Station) based at Bandelier National Monument in northern New Mexico. Craig conducts research on the ecology and environmental history of Southwestern landscapes, and the responses of Western mountain ecosystems and forests globally to climate change. He is a core principal investigator of the USGS Western Mountain Initiative, an integration of research programs that study global change in mountain ecosystems across the western United States. Recent and ongoing research activities include: integrated understanding of climate-induced tree mortality and forest die-off, including determination of global patterns and trends; development of ecological and fire histories in the southwest U.S.; ecological effects of recent fires on southwestern landscapes; ecological restoration of southwestern forests and woodlands; and developing long-term ecological monitoring networks across landscape gradients in the Jemez Mountains.
报告题目：Ecological Expression of Climate Change at Upper Treeline in the U.S. Rocky Mountains
Climate-vegetation interactions, the biogeographical manifestation of climate change in forest ecosystems, the role of bioclimatic thresholds in driving vegetation change, influence of climate on process-pattern interactions in vegetation communities.
