Distribution, Ecology, Disease Risk, And Genetic Diversity Of Swift Fox (Vulpes Velox) In The Dakotas, Emily Louise Mitchell
Distribution, Ecology, Disease Risk, And Genetic Diversity Of Swift Fox (Vulpes Velox) In The Dakotas, Emily Louise Mitchell
Electronic Theses and Dissertations
The swift fox (Vulpes velox), a native species once abundant throughout the Northern Great Plains (NGP), has declined due to changes in land use, historic predator eradication programs, and predation by larger canid species. Currently, the species is estimated to occupy 44% of its historic range. In the NGP, the status of the swift fox varies by state, ranging from furbearer to endangered species. However, knowledge of the current status of swift foxes in the NGP is lacking due to an absence of systematic population monitoring. Improving the current state of knowledge concerning swift fox populations in the …
Evaluating Bighorn Sheep Herd Response After Selective Removal Of Mycoplasma Ovipneumoniae Chronic Shedders, Tyler J. Garwood
Evaluating Bighorn Sheep Herd Response After Selective Removal Of Mycoplasma Ovipneumoniae Chronic Shedders, Tyler J. Garwood
Electronic Theses and Dissertations
Infected individuals vary in their contribution to disease persistence, and chronically infected individuals may sustain disease in a population. One disease that might persist in a population through chronically infected individuals is pneumonia in wild sheep. Mycoplasma ovipneumoniae (Mo), a pathogen of Caprinae commonly present in domestic sheep and goats, strongly correlates with pneumonia epizootics when it infects wild sheep populations. These epizootics can cause 40-100% herd mortality in an initial all-age dieoff, precipitate annual lamb mortality as high as 100% in following years, and sustain adult mortality long after initial all-age dieoffs. We conducted an experiment in the Black …
Changes In Wetland Conditions And Wetland Plant Communities In The Prairie Pothole Region After 50 Years, Ryann Cressey
Changes In Wetland Conditions And Wetland Plant Communities In The Prairie Pothole Region After 50 Years, Ryann Cressey
Electronic Theses and Dissertations
Wetlands in Stutsman County, North Dakota were revisited after 50 years to assess changes in wetland conditions and plant communities within wetland zones in the Prairie Pothole Region. In 1961-1966, Robert E. Stewart and Harold A. Kantrud conducted a study to investigate the relationship of wetland plant communities to variations of water permanence and chemistry on three study areas: Crystal Springs, Cottonwood, and Mt. Moriah. Within in this region, a severe drought occurred in 1988- 1992 followed by the longest deluge starting in 1993 with wetlands still impacted today. In 2013 and 2014, I revisited 80 of the original wetlands …
