Examination of the Viability of Bioelectrical Impedance Analysis (BIA)
to Determine Body Condition in Erethizon dorsatum (The North American Porcupine)

I examined the viability of bioelectrical impedance analysis (BIA) as a means for monitoring body condition in the North American porcupine (Erethizon dorsatum). This study was intended to calibrate a RJL Systems portable bioelectrical impedance analysis monitor to provide accurate measurements for total body fat in the North American porcupine. In addition to attempting to calibrate BIA equipment for use with Erethizon dorsatum, I also collected a data set of reactance and resistance readings using the RJL systems BIA monitor for the population of Erethizon dorsatum living in the St. Lawrence University Kip Tract natural area in the fall of 2003. From the data set it was hoped that an understanding of body fat deposition trends could be provided for the North American porcupine in the fall season in conjunction with helping me learn how effective a field technique BIA was for studying Erethizon dorsatum.
