Article Title:Resource depression on the Northwest Coast of North America

Abstract:
The mammal and fish faunal record from eight sites on the Columbia River (Oregon, USA) dating to the last 2000 years is examined to study subsistence change before and after European contact. Results show an increased use of low-ranked resources before contact and increased use of high-ranked resources after contact, trends that are predicted from changing demography and human predation pressure.
