| Popis: | Desert mule deer (Odocoileus hemionus eremicus) in central Arizona declined from 11 deer/km2 in the early 1960s to 2 deer/km2 in 2006. We had the opportunity to examine the causes of desert mule deer population fluctuations in Arizona from 1960 to 2006 by contrasting deer density, body condition, productivity, and diet quality inside and outside of the 259-ha Walnut Canyon Predator Proof Enclosure (WCPPE) on the Three Bar Wildlife Area (TBWA) in central Arizona. Mule deer inside the enclosure increased from 11/km2 in 1997 to 32 deer/km2 in 2004 while mule deer outside the enclosure in the TBWA remained between 1 and 5 deer/km2 during the same time. There was no difference in body mass and number of fetuses (in utero) between mule deer inside and outside the enclosure. However, there was evidence of mule deer in better body condition inside the enclosure compared to mule deer outside the enclosure. Mule deer inside the enclosure consumed a diet higher in energy than mule deer outside the enclosure... |
