Bear Heart Study


3:30 pm - Smith Center 202
Faculty Member: Lynne Nelson, Assistant Professor, Veterinary Clinical Sciences
Title of Conversation: Grizzly bear hibernation- What can we learn?



During a 5-6 month hibernation, grizzly bears do not eat, drink or eliminate body wastes yet they are able to maintain healthy organ function. We are interested in how grizzly bears are able to maintain normal heart function during this period, at heart rates that would result in congestive heart failure in a person. We have hand-raised 2 grizzly bears cubs that we are able to study heart function non-invasively (with ultrasound) and without sedatives or drugs. Preliminary results will be discussed.

4:30 pm - Smith Center 219
Faculty Member: James Krueger, Professor, Veterinary and Comparative Anatomy, Pharmacology and Physiology
