Spatial fingerprint of deglacial temperature change in eastern North America: More than one way to kill a spruce forest – Dr. Jack Williams
Dr. Jack Williams, UW Madison Thursday, January 30, 2020 4 pm, Nutting 100 The last deglaciation in eastern North America offers a classic system for studying climate-driven forest range dynamics during large and abrupt climate changes, but paleoclimate and paleofire records are surprisingly scarce. In this talk, I will first present new reconstructions of the spatial fingerprint of deglacial temperature variations in eastern North America, then focus on the collapse of spruce woodlands in the southern Great Lakes, to…

CONSERVATION PALEOBIOLOGY ON ACADIA’S MOUNTAINS – Caitlin McDonough MacKenzie
CONSERVATION PALEOBIOLOGY ON ACADIA’S MOUNTAINS Caitlin McDonough MacKenzie Second Century Stewardship Fellow University of Maine Monday, February 3, 2020, 12pm 138 Sawyer Conference Room Abstract: Conservation practitioners depend on accurate assessments of climate change vulnerability in allocating limited resources to protect and steward natural resources. The subalpine plants on Acadia National Park’s open granite ridges have been interpreted as post-glacial tundra relicts, however paleoecological records above treeline are sparse and this assumption remains untested. Could subalpine plant communities in Acadia represent persistent…
