    • Trends in grassland bird abundance following prescribed burning in southern Arizona

      DeStefano, Stephen; Mannan, R. William; Kirkpatrick, Christopher Kreitler (The University of Arizona., 1999)
      I examined trends in relative abundance and species richness of breeding and wintering grassland birds before (1996) and after (1997, 1998) a spring prescribed burn in a mesquite-dominated desert grassland at Buenos Aires National Wildlife Refuge, Arizona. The burn was moderate in intensity, patchy in extent, and affected ground cover more strongly than shrub cover, smaller shrubs more strongly than larger shrubs, and killed 1% of velvet mesquite (Prosopis velutina). Species richness of breeding birds decreased in the first year post-burn. Of breeding species, black-throated sparrows (Amphispiza bilineata) and mourning doves (Zenaida macroura) increased; whereas Botteri's sparrows (Aimophila botterii), Cassin's sparrows (Aimophila cassinii), and pyrrhuloxias (Cardinalus sinuatus) decreased in relative abundance. Breeding species characterized as not shrub-dependent exhibited changes that were more pronounced than those for shrub-dependent species. Of wintering birds, ladder-backed woodpeckers (Picoides scalaris) and vesper sparrows (Pooecetes gramineus) increased, and cactus wrens (Campylorhynchus brunneicapillus) decreased in relative abundance.

    • Tribal and individual American Indian trust funds: Who's in charge?

      Wilkins, David E.; Cook, Tracey Suzanne (The University of Arizona., 1999)
      The United States Government has allegedly mismanaged Individual Indian Money and Tribal Trust Fund accounts since their creation over 150 years ago. Despite what appears to be a well-documented and incontrovertible body of evidence: extensive governmental and private sector audits, as well as congressional and executive level reports and hearings confirming chronic mismanagement, the BIA continues to lose, misplace, and often fails to collect millions in royalty payments belonging to Indian people without an equitable solution. Consequently, this thesis examines the most recent reform effort, the 1994 American Indian Trust Fund Mismanagement Reform Act offered by the 103rd Congress, the Strategic Plan created by the Office of Special Trustee, and finally, federal and tribal responses to the proposed Strategic Plan. The impact of these varied responses has elucidated several hindrances to effective reform, thus generating key questions which necessitate closer examination in order to advance effective reform.
    • Tribal Colleges and Universities: Beacons of Hope, Sources of Native Pride

      Tippeconnic Fox, Mary Jo; Smith, Kestrel A.; Tippeconnic Fox, Mary Jo; Begay, Manley Jr.; Oberly, Stacey (The University of Arizona., 2014)
      This study examines whether Tribal Colleges and Universities impact hope and pride within their surrounding communities. As part of the investigation, data was gathered through the distribution of a ten question survey to three participants at both Diné College and Comanche Nation College: the president, a student, and a community member. Further data was collected through testimonials gathered from articles within the Tribal College Journal from the past six years (2008-2013). The goal of the study is to broaden the understanding of Tribal College and University impacts within their communities, and to provide valuable information for the college-community relationship throughout Indian Country.
    • Tribal Strategic and Sustainable Climate Change Adaptation: A Case Study of the Confederated Salish and Kootenai Tribes

      Gimblett, Howard R.; Rae, Lynn; Trosper, Ronald L.; Colombi, Benedict J. (The University of Arizona., 2020)
      Native nations are at the forefront of the climate change crisis and one of the most vulnerable populations to the impacts, but they also possess the most knowledge and experience with adaptation. A growing number of Native nations and tribal institutions are preparing for climate change and developing strategies, formal plans, and initiatives to increase the resiliency of their communities. Moreover, many American Indian tribes are considered models for climate change adaptation because they are tackling complex climate change problems across multiple scales with fewer resources to increase the resiliency of their communities. Previously published research shows that Native nations that exercise sovereignty and self-governance while maintaining cultural continuity are having greater success at managing their land and natural resources (Jorgenson 2007). There is, however, limited understanding of tribal climate change adaptation and additional information is needed to understand how tribes are exercising self-governance and approaching climate change issues to advance adaptation planning and implementation. The purpose of this research is to identify and consider some of the challenges of tribal climate change adaptation and the strategic approaches that tribes are using to manage and protect their land, natural resources and communities. This research involves a limited review of the tribal natural resource planning and climate change adaptation literature, and a case study with the Confederated Salish and Kootenai Tribes (CSKT) of the Flathead Reservation to assess the strategies and resources utilized by their communities to support adaptation planning. A total of 11 semi-structured interviews were conducted with CSKT leaders and department representatives to consider tribal perspectives and experiences in the adaptation planning and implementation process. Additionally, a small group discussion was conducted with CSKT Elders to understand how climate change is affecting the Tribes’ communities and cultures. This research and the case study findings demonstrate the transformative potential for tribal community development and climate change adaptation when aspects of tribal sovereignty, self-governance, and strategic and sustainable natural resource management are embedded into tribal planning and decision-making processes. While there are varying challenges and complexities associated with tribal climate change adaptation that must be considered, the findings offer examples and insights that may help other tribes further develop existing strengths, protect cultural and spiritual values, and increase community resilience. This research also considers future research needs and next steps to support tribal climate change adaptation.

    • Tribes, Water, and Economic Characteristics of the Western United States

      Colby, Bonnie; Young, Ryan Michael Coatsworth; Thompson, Gary; Scheitrum, Daniel (The University of Arizona., 2019)
      Native American tribes in the Western United States experience persistent socio-economic challenges that impede economic development and improved standards of living within their communities. In this study, U.S. Census Bureau data on tribes is linked with additional data sources to perform econometric analyses to better understand how “tribal presence” explains economic well-being. This study finds, as expected, that “Tribal Presence” (created from percent of tribal land and percent of Native American population ) has a significant negative relationship with Per Capita Income at census tract and county spatial scales. Consistent with the findings on income, the Tribal Presence variable has a significant negative relationship with Percent Families Above Poverty. Variables for education, internet access, urban population, and climate were also significant determinants for income and family poverty. The climate variable results were interesting as they infer that the more unusually dry or wet it is, the more income and more poverty there is. Further analysis of counties with “tribal presence” was conducted to better understand how counties with tribes who have quantified water rights compare to counties with tribes who have yet to quantify water rights.
    • Trichomonas gallinae in avian populations in urban Tucson, Arizona

      Shaw, William; Hedlund, Charise Ann, 1966- (The University of Arizona., 1998)
      I studied Trichomonas gallinae, a flagellated protozoan that is the causative agent of the avian disease trichomoniasis. The purpose of my study was to assess (1) the incidence of trichomonads in wild birds, (2) the prevalence of trichomonads in water sources utilized by wild birds, and (3) possible methods to control the transmission of trichomonads in water sources utilized by wild birds. I trapped 403 birds during 1994 and 1995. Approximately 1/3 of these birds tested positive for T. gallinae, however, none exhibited any signs of lesions. I collected water samples from 10 bird baths, isolating flagellated protozoa from 2 of them. I could not identify the species of flagellated protozoa. I determined that high temperatures (50°C), near ultra-violet radiation, and natural sunlight are effective against trichomonads. In addition, the highest effective dilutions of Chlorox, Nolvasan, and distilled white vinegar active against trichomonads were determined.
