Résumé
I evaluated the effects of simulated noise from low-flying jet aircraft on the behavior and physiology of 6 captive desert mule deer (Odocoileus hemionus crooki) and 5 captive mountain sheep (Ovis canadensis mexicana). I measured heart rate, body temperature, ambient temperature, and behavior related to the number of overflights/day, and decibel levels (dB) animals were exposed to (range = 92-112). I recorded heart rate and body temperatures from transmitters implanted into the body cavity of animals. Ambient temperature was recorded in the pens and behavior was described from visual observations. I compared heart rates during simulated overflights by jet aircraft (N = 112/season) of sheep and deer to data collected prior to and following treatments. I documented differences between heart rates, species, dB levels, and number of overflights/day within and between seasons. All animals became habituated to aircraft noise. Although heart rates increased during overflights, they returned to the resting heart rate in ≤ 2 minutes.
