About the Author
Steven C. Amstrup is a Research Wildlife Biologist with the Unites States Geological Survey at
the Alaska Science Center, Anchorage AK. He holds a B.S. in Forestry from the University of
Washington (1972), a M.S. in Wildlife Management from the University of Idaho (1975), and a
Ph.D. in Wildlife Management from the University of Alaska Fairbanks (1995).
Dr. Amstrup has been conducting research on all aspects of polar bear ecology in the Beaufort
Sea for 24 years. His interests include distribution and movement patterns as well as population
dynamics of wildlife, and how information on those topics can be used to assure wise
stewardship. He is particularly interested in how science can help to reconcile the ever-enlarging
human footprint on our environment with the needs of other species for that same environment.
Prior work experiences include studies of black bears in central Idaho, and pronghorns and
grouse in Wyoming. On their honeymoon in New Zealand in 1999, Steven and his wife Virginia
helped in a tagging study of little blue penguins. That experience gave Steve the honor of being
one of the very few people ever to have been bitten by both polar bears and penguins.
