Effects of Simulated Aircraft Noise on Heart-Rate and Behavior of Desert Ungulates
Abstract
We evaluated the effects of simulated low-altitude jet aircraft noise on the behavior and physiology of captive desert mule deer (Odocoileus hemionus crooki) (n- 6) and mountain sheep (Ovis canadensis mexicana) (n -5). We measured heart rate, body temperature, and behavior in relation to ambient temperature, number of simulated overflights/day, and noise levels (range - 92-112 decibels (dB)) that the animals were exposed to. We compared heart rates during simulated overflights (n - 112/treatments/season) to data collected prior to and following treatment periods. We documented differences between heart rates for animals, noise levels, and number of overflights between seasons. All animals became habituated to sounds of low-altitude aircraft. Although heart rates increased during overflights, they returned to resting rates in less than or equal 2 minutes. Aircraft, Behavior, Desert mule deer, Mountain sheep, Noise
