Long‐term ecological changes in marine mammals driven by recent warming in northwestern Alaska
Abstract Carbon and nitrogen isotopes analyses were performed on marine mammal bone collagen from three archaeological sites ( ad 1170–1813) on Cape Espenberg (Kotzebue Sound, northwestern Alaska) as well as modern animals harvested from the same area to examine long‐term trends in foraging ecology...
