Does intensive forest management affect innate immunity of wild deer mice (Peromyscus maniculatus)?

Creator:: Rogers, Natalie M., Hanselmann, Rhea, and Jolles, Anna E.
Abstract:: To examine the influence of forest management on wildlife immunity, the innate immune system of wild deer mice (Peromyscus maniculatus) inhabiting forest plots of different management intensities in the Oregon coast range was measured by bactericidal assay. Bactericidal activity was compared across three management levels, including 40-50 year old forest...

Comparison of complete blood count and biochemistry panels between cats with and without clinically apparent feline upper respiratory tract disease

Creator:: Duke, Sarah M.
Abstract:: Feline upper respiratory tract disease (FURTD) is a complex syndrome that affects domestic cats, with clinical signs including general malaise, ocular and nasal discharge, and oral pathology. Our study compared the presence or absence of five common FURTD pathogens and routine blood parameters between 18 participating cats. Owners tended to...

Wildlife Health in Managed Forests : Immunity and Infectious Diseases in Wild Rodents of Oregon

Creator:: Hanselmann, Rhea
Abstract:: With continual and worldwide human population growth, our impact on the natural environment expands and intensifies every day. We consume natural resources, burn fossil fuels, and release toxic compounds into the air, water, and earth. We build roads that fragment the landscape, construct new settlements, and develop agricultural lands in...

Using the Microbial Tree of Life to Describe Mammalian Health and Disease

Creator:: Arnold, Holly Kristin
Abstract:: The past decade of research has potentiated a revolution in our understanding of mammalian health and evolution by revealing that the gut microbiome plays a central role in mammalian physiology. Our ability to unlock this potential hinges upon the identification of specific groups of gut microbes that elicit effects on...

Exploring the distribution of waterborne pathogens Giardia and Cryptosporidium along a land-use gradient in Oregon in the context of One Health

Creator:: Aleman Torres, Mariangel
Abstract:: Giardia and Cryptosporidium protozoans are resilient, zoonotic waterborne pathogens that can bypass water treatment and kill millions of people and animals annually. Giardia and Cryptosporidium cysts and oocysts, respectively, can spread through feces; poor sanitation and poverty can increase the risk for giardiasis and cryptosporidiosis diarrheal diseases. We are currently...

How sweet is the land? Modeling caloric landscapes for tropical hummingbirds

Creator:: Birkett, Christina Nozomi and Birkett, Nozomi Fukui
Abstract:: Pollination is a critical ecosystem function for sustaining biodiversity. However, pollinators and the services they provide are threatened by landscape-altering anthropogenic activities across the globe. Habitat loss and fragmentation, introduction of invasive species, chemical use, and urbanization have been shown to impact pollination. Pollinator foraging behavior is thought to be...

Trade-offs in a pathogen-rich world : genetic and maternal drivers of variation in costly resistance and immunity in African buffalo (Syncerus caffer)

Creator:: Tavalire, Hannah F.
Abstract:: Disease acts as a powerful selective force in natural systems, driving the rapid evolution of resistance in the host. In the face of a myriad of pathogenic challenges in natural systems, hosts must balance the energetic needs of maintenance and reproduction with costly resistance mechanisms. In this dissertation I will...

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...

Ontogenetic Shifts in Disease Response in Native and Invasive Anuran Species

Creator:: Urbina Gonzalez, Jenny Cecilia
Abstract:: This dissertation presents a different approach to understanding how amphibians are responding to disease through ontogeny. Although numerous efforts have been conducted to understand host responses to the fungus Batrachochytrium dendrobatidis (Bd), studies have been restricted to distinct developmental stages. This dissertation provides information on host response to Bd across...

Disentangling the Biotic and Abiotic Drivers of the Amphibian Disease Chytridiomycosis

Creator:: Bradley, Paul W.
Abstract:: The ongoing worldwide loss of biodiversity has been described as a "biodiversity crisis," "the Anthropocene defaunation," and alternatively "an extinction spasm." More recently, many scientists have come to the conclusion that we are witnesses to Earth's sixth major mass extinction event, which has the potential to fundamentally alter basic ecological...
