Abstract
This chapter summarizes the environmental and ecological history of the Arctic Foothills in Northern Alaska. It characterizes the responses of terrestrial and aquatic ecosystems to climatic changes of the past ~30,000 years. It highlights pollen records of changing vegetation composition which are abundant in the arctic foothills in studying responses to climate change. It describes the paleo-environmental environment across four periods: Glacial Interval (~27,000-15,000 yr BP), Late Glacial (~15,000-11,500 yr BP), Early Holocene (~11,500-7,500 yr BP), and Middle to Late Holocene (~7,500 yr BP to present).
