Early spring at Tutakoke River field camp

More about this image
For this U.S. National Science Foundation-supported Arctic research project, led by Karen Beard of Utah State University, researchers are studying how a warming Arctic is affecting the relationships between migratory animals -- specifically, the Pacific black brant (Branta bernicla nigricans), a species of wild goose -- and the annual cycle of the forage they rely on for energy, nutrition and rearing of young. The researchers want to know how climate change is affecting the arrival time of the geese and the start of the growing season in the Yukon-Kuskokwim Delta.
