Upcoming lecture at ISU. Note that the Thursday night lecture is the official Errington Memorial Lecture and intended for a general audience. The Friday afternoon lecture will likely be geared a bit more toward students and faculty, but interested members of the public are always welcome. Both lectures are free. The Errington Memorial Lecture Thursday, 15 October 2009 7:00 p.m., Great Hall, Memorial Union Iowa State University, Ames, Iowa Dr. Robert Rockwell American Museum of Natural History, Ornithology Department Professor of Biology, City College of The City University of New York "The Early Bear Gets the Goose: Polar Bears, Snow Geese, and Climate Change" Natural Resource Ecology & Management Seminar Friday 16 October, 3:10 p.m. 164 E Lagomarcino "Lesser snow geese: ecoterrorists of the tundra?" Dr. Rockwell is widely known for his work as lead investigator on the Hudson Bay Project, which studies coastal arctic tundra ecosystems and their conservation. He has directed the snow goose research program at La Pérouse Bay near Churchill, Manitoba, for nearly 25 years. His most recent work, published in Polar Biology, discusses polar bear predation on snow goose populations due to the earlier annual breakup of sea ice. Dr. Rockwell has studied the population ecology of the lesser snow goose and its effects on arctic marshes, Common Eiders of Greenland and Canada, the birds of Wapusk National Park (Hudson Bay, Canada), the Yukon-Kuskokwim Delta of southwest Alaska, the genetic structure of wildlife populations, and other topics. At the City University of New York, Dr. Rockwell teaches population ecology, biostatistics, and conservation biology. His research is in population dynamics, community ecology, lifetime reproductive success, and the genetic structure and gene flow of migratory waterfowl such as snow geese, emperor geese, northern pintails and spectacled eiders. Rockwell is a research associate with the American Museum of Natural History Ornithology Department and a professor at CUNY City College.
