Title: Responses of River Otters to Oil Contamination: A Controlled Study of Biological Stress Markers

Project Year and Number: 2000: 00348-CLO

Other Fiscal Years and Numbers for this Project: 1999: 99348, 1998: 98348

Principal Investigator (PI): Merav Ben-David, University of Wyoming

Assisting Personnel: Terry Bowyer, Lawrence Duffy

Research Location: Prince William Sound

Restoration Category: Research

Injured Resources Addressed: River Otters

Abstract: This project will complete data analyses and manuscript preparation for Project /348, which was designed to explore the effects of oil contamination on physiological responses in river otters. Fifteen captive otters were exposed to two levels of oil contamination under controlled conditions at the Alaska SeaLife Center. Samples of blood, tissues and feces were collected for analysis of biomarkers and for immunological examinations. A wealth of data was collected during the experiment phase. Completion of data analyses and publication of results are especially important in light of the recent listing by the Trustee Council of river otters as a recovered species.
