Utah prairie dogs (Cynomys parvidens) have been extirpated in 90% of their historical range. Because most of the population occurs on private land, this threatened species is continually in conflict with landowners. The Utah Division of Wildlife Resources has been relocating prairie dogs from private to public land since the 1970s, but relocations have been largely unsuccessful due to high mortality. Prairie dogs are highly social animals, but they are usually relocated without regard to their family group (coterie). I hypothesized that relocating Utah prairie dogs with their social structure intact may positively affect their survival rates and behavior. Utah prairie dogs were relocated from the golf course in Cedar City, Utah to two prepared sites near Bryce Canyon National Park, Utah in 2010 and 2011. Trapped animals were individually marked, and released at the new sites. Prairie dogs were relocated as coteries, or in a control group as randomly trapped individuals. To compare the two sites, vegetation transects were established at each site to document differences in composition and structure. Two months after relocation, traps were set to recapture released animals. Activity budgets were collected prior to, and following, relocation. Activity data were also collected on wild prairie dog populations for comparison. The best predictor of survival and recapture rate was the animal’s weight at initial capture. Larger animals had higher survival, but lower recapture rates. More research is needed to determine if this is due to better body condition, older animals having more experience, or both. Analysis showed no evidence of an advantage to relocating Utah prairie dogs by coteries. There was no benefit to survival, and no difference in behavior between coterie and control relocation strategies. Relocated animals behaved differently from non-relocated prairie dogs. While still significantly different, relocated individuals behaved more like wild prairie dogs than the animals at the urban source population. The vegetation at the two sites was significantly different. One site had significantly less grass cover, more invasive plant cover, and rockier soils. The sites also had different soil structures, which affect burrowing, and long-term retention rates. More research is needed to determine how site selection influences long-term success of a relocation site.

Using GIS, this study creates a predictive model of a distinct population of French-Canadian settlers, highlighting shared environmental characteristics of known sites that may have factored into their decision-making process as they chose locations for their farmsteads. While traditional historic and archaeological research has been conducted on French Prairie, the advent of GIS and readily available data sets facilitated this first multivariate, statistical, predictive model of French-Canadian settlement. This study explored theoretical and logistical issues of predictive modeling and determined that this population may be uniquely suited to predictive modeling. Here, however, substantiating a previous settlement pattern was problematic and the variables used produced a weak predictive model. One by-product of this research was the digitalization, rectification and analysis of 1852 GLO maps of the French Prairie during the development of the "known sites" data theme. As an initial attempt at modeling, this study points to the need for ongoing archeological testing and modeling efforts as development on and around French Prairie threatens archaeological resources. The study suggests other environmental and social variables for further testing. / Graduation date: 2005

Reticuloendotheliosis virus (REV) is a retrovirus that causes a neoplastic disease in a wide range of avian hosts including chickens, turkeys, and ducks. In 1993, REV was detected in the endangered Attwater's prairie chicken (Tympanachus cupido attwateri), a subspecies of Tympanachus cupido. Subsequent infections of this prairie chicken have been identified at captive breeding facilities throughout Texas. The implications of these infections have severely hindered repopulation efforts by these facilities. This study focused on investigating REV infection of captive Attwater'€™s prairie chicken in order to better understand the disease affecting these endangered birds. The overall objective was to develop a means of eliminating this threat to the repopulation of the Attwater's prairie chicken. Several aspects of virus infection were investigated. Reagents capable of recognizing prairie chicken IgY and viral gag polypeptides were developed for use in assays for detection of antibody responses and titration of viral concentrations. Sequencing data of genomes collected from isolates of Texas prairie chickens and domestic chickens, as well as three REV prototype viruses, were compared to determine relationships among strains and identify the potential origin of the REV infecting Attwater'€™s prairie chicken. Additionally, a flow cytometry technique of segregating the lymphocyte population from peripheral blood mononuclear cells (PBMC) using a pan leukocyte monoclonal antibody was developed to more accurately measure changes within lymphocyte populations. This technique combined with intracellular labeling was used to deduce the target cells of REV infection. A nested polymerase chain reaction (PCR) test was developed for greater sensitivity in detecting infection in birds than the previous method of single amplification PCR. This greater sensitivity results in earlier identification of the virus in infected birds, which allows for earlier removal of infected birds to minimize transmission of the virus throughout the flock. The sensitivity of the nested PCR diagnostic test was determined in a dose response pathogenesis study, which was conducted on hybrid greater/Attwater's prairie chicken to observe the experimental development of disease in these birds. Finally, a vaccine was developed using plasmid DNA with REV encoded genes and tested on naturally infected prairie chickens to determine its efficacy in reducing viral load. Although no reduction in viral load was detected, the vaccine may be effective in providing prophylactic protection in future studies.

This thesis explores how nineteenth century Métis concepts of family and community have found expression in post 1930s urban development, governance and political activism. In this study, genealogical methods and participant interviews have been used to examine the social, economic and political role of women in 19th century Métis families and communities in order to determine the extent to which these traditional roles were carried forward into an urban context prior to World War II. Based on this research, it was concluded that female kinship relationships were central in structuring and determining the bounds of this Métis community despite economic changes, community movement, physical relocation and political upheaval in both traditional and contemporary contexts. By organizing in ways that were familiar and consistent with past practices, urban Métis women in the early twentieth century had the opportunity and flexibility to informally politicize community issues and recruit organization participants. Over time, the political role played by women evolved and they began to take leading roles in the day-to- day operation of programs and services. By the 1960s-70s, urban Métis women began to formally assert their political will and move from behind the scenes into a more public leadership roles. Throughout this evolution, concepts of family, kinship and tradition remained the core organization concept for this community. Through the expression of these 19th century traditions, Métis women have made a significant contribution to post-1930 urban development, governance and political activism.

Lesser prairie chicken (Tympanuchus pallidicinctus; LPC) numbers have declined considerably in Texas since the early 1900s. As with other prairie chicken species, reasons for declining ranges and numbers have been attributed primarily to degradation and fragmentation of habitats. Until my study, no telemetry-based research on LPC has been conducted in the Rolling Plains of the Texas Panhandle. I radio-tagged and monitored LPCs in 2001 (spring??winter) and 2002 (spring) at a stable population in a native rangeland landscape (Study Area I) and in a declining population in a fragmented rangeland and agricultural landscape (Study Area II). No significant (P < 0.05) differences in survival were detected for combined study areas between years, or between study areas within years. Ranges and movements, as independent criteria by season, sex, and age classes combined were similar (P > 0.05) for both study areas. Lesser prairie chickens predominately occupied native rangeland cover types (>85%) compared to non-native rangelands at both study areas. Total invertebrate dry mass for all orders differed between native rangeland and Conservation Reserve Program (CRP) sites at Study Area II. Over 32 times more dry mass of invertebrates was collected at the native rangeland site than were collected at the CRP site. Herbaceous cover differed significantly for grasses (P < 0.01), forbs (P < 0.01), and bare ground (P < 0.01), but not for litter (P = 0.43) or woody cover (P = 0.63) between study areas. The similar range sizes, movement distances, and cover use observed for both study areas may provide insight into minimum area requirements for LPCs within the Rolling Plains in the Texas Panhandle.
