Diet Reconstruction Of Bighorn Sheep (Ovis Canadensis) Using Stable Isotopes, Joshua M. Whitaker
Diet Reconstruction Of Bighorn Sheep (Ovis Canadensis) Using Stable Isotopes, Joshua M. Whitaker
Theses and Dissertations
We determined the diet contributions of grasses, forbs and shrubs for three herds of bighorn sheep along the Wasatch Front, Utah using stable isotope techniques and determined the electivity values for different forage species for four herds. Forbs were generally the most common forage eaten across all herds while shrubs were the least used forage resource. The Provo Peak and Mount Nebo herds used grasses, forbs and shrubs at proportions similar to other bighorn sheep populations across the west, while the Antelope Island herd used forbs at higher levels than any other local herd. Additionally, the herd on Antelope Island …

Diet Reconstruction Of Wild Rio-Grande Turkey Of Central Utah Using Stable Isotope Analysis, Benjamin D. Stearns
Theses and Dissertations
The wild turkey is endemic to North America and has played a role in human cultures past and present. However, with the turkey's elusive behavior some aspects of its ecology are challenging to understand. Diet is one of these difficult aspects to study. The purpose of this study was to determine the diet selection of wild turkeys in central Utah using non invasive stable isotope technology. We hypothesize that turkey diet is highly specific, that consumption of specific plant species correlates with the needs of the individual turkey, and that stable isotope analysis will reveal patterns in annual dietary intake. …
