OU, BU and Smithsonian researchers investigate ancient species in Gulf of Alaska

(University of Oklahoma) Invasive species have shaped island ecosystems and landscapes in the Gulf of Alaska, but their histories are unknown. In a study by the University of Oklahoma, Boston University and the Smithsonian Conservation Biology Institute, researchers investigated the archaeological and genetic history of the Arctic ground squirrel on Chirikof Island, Alaska. This small mammal has the ability to affect vegetation and seabirds on these islands and was introduced across much of this region as part of the historic fox farming industry.
