Invasive species have shaped island ecosystems and landscapes in the Gulf of Alaska, but their histories are unknown. Researchers have now 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.
