Assessing body fat percentage of grizzly bear

Detailed Description

Field personnel use bioelectrical impedance to assess body fat percentage of captured bears.  The procedure is similar to how body fat is measured in humans and is based on the resistance of body tissues to the flow of a small, harmless electrical signal.  The electrical current is impeded more by fat tissues compared with tissues that are composed mostly of water, thus providing a useful measure of body composition and percent body fat. These data allow scientists to examine how environmental changes may influence body condition of individual bears.
