Evaluation Of Survey Methods And Development Of Species Distribution Models For Kit Foxes In The Great Basin Desert, Stephen J. Dempsey
Evaluation Of Survey Methods And Development Of Species Distribution Models For Kit Foxes In The Great Basin Desert, Stephen J. Dempsey
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Historically, kit foxes (Vulpes macrotis) once occupied the desert and semi-arid regions of southwestern North America, ranging from Idaho to central Mexico. Their range-wide decline has warranted the kit fox to be designated as a state sensitive species in Utah. Once considered the most abundant carnivore in western Utah, the kit fox has been in steep decline over the past decade, creating a demand to determine kit fox presence in the Great Basin desert. Currently there is little consensus on which survey methodology is best for detecting kit fox presence. We tested 4 survey methods (scat deposition, scent …

We conducted a turtle mark-recapture program within a 160 m stretch of the Fredericksburg Canal with standard, baited hoop nets from May to July 2012 to determine if a population of the introduced Red-eared Slider (Trachemys scripta elegans) and Yellow-bellied Slider (Trachemys s. scripta) are established in this area. We captured and marked nine Red-eared Sliders (1 male, 8 females) and estimated a population size of 23 individuals. Most were reproductively mature. The established population in the canal may be a source of introduction into the Rappahannock River.
