Incorporating Uncertainty into Recovery Goals for Endangered Species (Undergraduate Researcher Matt Zak)

The objective of this study was to evaluate the mention of uncertainty (i.e., variance) associated with population size estimates within U.S. recovery plans for endangered animals. To do this all finalized recovery plans were reviewed for listed terrestrial vertebrate species. It was found that more recent recovery plans reported more estimates of population size and uncertainty. Also, bird and mammal recovery plans reported more estimates of population size and uncertainty. It was recommended that updated recovery plans combine uncertainty of population size estimates with a minimum detectable difference to aid in successful recovery.  Click here for a copy of the paper online.

Fecal Testing, Baiting & White-tailed Deer (Undergraduate Researcher Teah Nauman Snyder)  

The baiting and supplemental feeding of white-tailed deer has been used to help with nutrient deficiencies that may occur during the winter season in temperate areas and to help increase hunting success.   However, many states in the U.S. have banned the practice of baiting for deer based on the philosophy of fair chase and potential spread of diseases.  This experiment investigates the possibility that there are certain chemical signatures left in deer feces that could indicate the presence of an illegally baited site.  Two populations of white-tailed deer were separated into control and experimental groups, with the experimental group exposed to Deer Cane® brand deer bait.  Using a Chloride Ion Probe and Atomic Absorption Spectroscopy, we found no difference in chloride ion or sodium and calcium cation concentrations in white-tailed deer feces between the control and experimental deer populations.  In addition, the use of Gas Chromatography-Mass Spectroscopy and Thin Layer Chromatography were not able to pick up the presence of Deer Cane® deer bait in deer feces.

Urine Deer-based Lure Testing (Undergraduate Researcher Ken Strauser)  

The Pennsylvania Game Commission contacted Millersville University to perform tests to help combat the transmission and spread of Chronic Wasting Disease (CWD) via better detection of urine-based deer lures. The objective of this study was to use multiple methods and kits for detection of urine and blood to determine the best method of detection for urine-based deer lures.  Kits and methods included Uritrace®, Nite-SiteTM luminol, Hemascein® and Ultra-violet (UV) light.  We found that no one technique showed a positive for all urine-based deer lures.  The UV light and Uritrace methods were the most effective and the UV light was the best technique for the field.  These findings are helpful in determining the best method to detect urine-based deer lures to help mitigate the spread of CWD.
