Aerial counting experiments to estimate pronghorn density and herd structure
Article Abstract:
Aerial surveying is the most preferred method of estimating the size of animal populations, despite their apparent inconsistencies. To illustrate the inadequacies of aerial surveying, a study was conducted to determine pronghorn populations using quadrat, strip and line surveying. The results showed significant differences in the estimation of each surveying technique. Nonetheless, each surveying technique is useful in determining specific factors such as density, age and sex ratios.

Using known populations of pronghorn to evaluate sampling plans and estimators
Article Abstract:
Sampling plans and abundance estimators based on aerial surveying continue to be the most widely-used methods of studying animal populations. However, the accuracy of sampling plans and estimators can be compromised, particularly in cases where true animal populations are unknown. An evaluation of the most common sampling plans and estimators was conducted. The results support the contention that the accuracy of such methods can be hampered by unknown animal populations.

Neonatal mule deer fawn survival in west-central Colorado
Article Abstract:
The likelihood of fetus mortality during late pregnancy or mortality of fawns at birth as potential causes of poor recruitment is studied. Findings from a sample captured from west-central Colorado suggest that most does were bred during their first estrus cycle and neonatal survival of does through 14 December did not completely account for the observed low fawn:doe (f:d) ratios.
