Myrtle's work during the summer of 1998
with Dr. Ben-David resulted in an
opportunity to collaborate with the Prince William Sound Science Center
during the summer of 1999. Join Myrtle in her summer endeavors!

Responses of River Otters to Oil Contamination:
A Controlled Study of Biological Stress Markers, Diving Physiology and
Dr. Merav Ben-David, Institute of Arctic Biology,
University of Alaska - Fairbanks
Previous studies on wild river otters inhabiting oiled shores in Prince William Sound, Alaska, have suggested that these otters suffer from chronic stress related to oil consumption. Oiled otters had lower body mass, larger home ranges, less diverse diet as well as elevated blood chemicals compared with otters from non-oiled areas. This indicates that oil contamination may have an effect on otter health through their ability to dive and catch prey. This project is designed to explore the effects of oil contamination on the health and behavior of river otters experimentally. Fifteen wild caught otters will be exposed to two levels of oil contamination under controlled conditions in captivity. Samples of blood, tissues and feces will be collected for chemical analysis. Results from these experiments with known doses will be invaluable for comparisons with similar data collected from free-living otters. Parcticipants will conduct behavioral observations on river otters foraging on schooling fish in captivity, and behavioral responses to fish to foraging otters, to explore the effects of oil contamination on diving and foraging success.
