Hidden dynamics : community ecology and costs of parasite infection in African buffalo (Syncerus caffer)

Creator:: Henrichs, Brian
Abstract:: Most wild animals are concurrently infected with multiple parasite species for most of their lives. These parasite species assemble into rich and diverse communities, with parasites using host tissues for growth and reproduction as well as evolving strategies to evade the host immune system. The net effect of these ecological...

Dispersal Behavior in African Buffalo (Syncerus caffer) : Tradeoffs Between Nutritional Resources and Disease Exposure

Creator:: Spaan, Robert Steven
Abstract:: Dispersal facilitates population health and maintains resilience in species via gene flow. Adult dispersal occurs in some species, is often facultative, and is poorly understood, but has important management implications, particularly with respect to disease spread. Although the role of adult dispersal in spreading disease has been documented, the potential...

Effects of genetic drift, natural selection, and population connectivity on adaptive-linked genetic diversity of desert bighorn sheep

Creator:: Nickerson, Brandon Scott
Abstract:: The amount and distribution of neutral and adaptive genetic diversity are often assumed to follow similar patterns. However, natural selection on adaptive loci may cause divergence from patterns observed for loci which are only influenced by selectively neutral processes such as genetic drift. The interaction between selection and neutral processes...

Walrus Vibrissae: Determining Growth Rate, Indication of Niche Variability, and Implications for Climate Resiliency

Creator:: Blackfield, Danielle
Abstract:: Pacific walrus (Odobenus rosmarus) are particularly vulnerable to the impacts of climate change due to the high reliance on sea ice for safety, transport, and social behaviors. Additionally, the walrus diet consists of predominantly bivalves, whose populations are in decline as a result of ocean acidification. We first determined the...

Modeling the Dynamics of Vector–host Interactions in Avian Communities: Eastern Equine Encephalitis Virus as a Model System

Creator:: Muller, Timothy
Abstract:: Understanding the dynamics of seasonal epizootics of vector-borne pathogens infecting multiple host species presents several challenges. The transmission potential of competent hosts depends on factors influencing the contact rate between hosts and vectors. Feeding preferences of vectors can determine which host species drive the prevalence of infection throughout the overall...

The influences of habitat structure and landscape heterogeneity on African buffalo (Syncerus caffer) group size in Hluhluwe-Imfolozi Game Reserve, South Africa

Creator:: Dora, Cathleen Anna
Abstract:: This study aimed to connect habitat and landscape scale variation, through time and space, to wildlife population dynamics. I studied African buffalo (Syncerus caffer) group size according to habitat structure, landscape heterogeneity, forage quality, and water availability in Hluhluwe-iMfolozi Game Reserve, South Africa. I used two approaches to study grouping...

Oppression from Within : AIM, Heteropatriarchy, Settler Colonialism, and the Death of Anna Mae Aquash

Creator:: Whitebear-Cupp, Luhui
Abstract:: This thesis describes how heteropatriarchal, settler colonialism impacted Indigenous communities' systems in power and control, particularly with the American Indian Movement during the 1960s-1970s. Further, the gendered divides this created within the American Indian Movement are described. The murder of Anna Mae Aquash is revisited as an act of gendered...

Hazardous materials commodity flow study for Linn, Benton, and Lincoln counties, Oregon

Creator:: Wemple, Bryan E.
Abstract:: Hazardous materials data from business and industrial chemical information and incident databases were analyzed to study the types of chemicals located in Linn, Benton, and Lincoln Counties, Oregon. Federal and Oregon Department of Transportation data were analyzed to study traffic patterns and truck and railroad traffic levels. Results indicate more...

An evaluation of the use of menu risk assessment as a tool in food service protection programs

Creator:: Gray, Lori A.
Abstract:: Despite the increase in information on the causes of foodborne disease, outbreaks continue to be a major preventable public health problem. Current food service establishment inspection programs, however, are not designed to assess the potential of risk for foodborne disease and do not focus prevention efforts where food service problems...

Health risks associated with exposure to stainless steel arc welding fumes and gases

Creator:: Chadim, Charles
Abstract:: Electric arc welding is the most prevalent welding type in industry. It creates two main groups of health hazards for workers; fumes and gases, and radiant energy. Shielded Metal Arc (SMA) welding is the most widely used welding method in industrial plant welding shops. The main chemical health hazards associated...
