Abstract: Presents research on the fish communities in the foothills region of the North Slope of Alaska and presents a geomorphic-trophic model for landscape control of Arctic lake food webs. Why the arctic is suitable for understanding the relationships between geomorphic setting, fish distribution, and lake trophic structure; How lake trout serve as keystone predators; Food source of lake trouts; Geomorphic constraints in arctic Alaskan lakes; Importance of landscape features to lake food webs.
