Assessing Apparent Effects on Survival and Movement of Desert Bighorn Sheep (Ovis canadensis nelsoni) Following a Pneumonia Outbreak

Creator:: Dekelaita, Daniella J.
Abstract:: In the western United States, bighorn sheep (Ovis canadensis) have suffered major die-offs in every state since the mid-1800s, and disease from domestic sheep (Ovis aries) has been a primary factor in these events. Beginning in the early 1900s, poly-factorial, poly-microbial pneumonia was identified as a major disease affecting bighorn...

Characterizing the Spread and Consequences of Mycoplasma ovipneumoniae on Bighorn Sheep (Ovis canadensis) in the Northern Basin and Range Ecosystem

Creator:: Spaan, Robert S.
Abstract:: North American bighorn sheep (Ovis canadensis) have experienced significant declines and population extirpations due to novel pathogens such as Mycoplasma ovipneumoniae. This disease continues to limit the population restoration of bighorn sheep. Therefore, understanding the demographic consequences of pathogen presence and the risk of contact between bighorn populations and potential...

A Contingency-Based Evaluation for Beaver Restoration of Salmon Habitat in Oregon Coastal Streams

Creator:: Stevenson, John R.
Abstract:: Streams across the western United States are impaired from human alterations that have reduced freshwater habitat by simplifying channel complexity and disconnecting floodplains (Knox et al., 2022; Waples et al., 2008; Wohl, 2014). Climate change is likely to continue exacerbating these risks by warming summer surface stream temperatures (Crozier et...

Structure and Dynamics of the Canine (Canis familiaris) Nasal Microbiome

Creator:: Knorr, Elizabeth
Abstract:: The diverse community of bacteria living within and on host organisms, known as the microbiome, has an important role in maintaining host health. Dysbiosis, known as a change in the healthy community of the microbiome, has been associated with a number of diseases across host organisms and body sites including...

Life in a Rapidly Changing Environment: The Thermal Biology of the Red-sided Garter Snake (Thamnophis sirtalis parietalis)

Creator:: Hubert, David L.
Abstract:: At a time when environmental conditions are rapidly changing, understanding how thermal extremes impact wildlife is imperative to fully understanding the consequences of climate change in natural ecosystems. While many organisms are currently impacted by rapidly warming and more erratic environmental conditions, identifying and investigating model species whose life histories...

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...

Use of Controlled Blasting to Quantify the Dynamic, In-Situ, Nonlinear Inelastic Response of Soils

Creator:: Jana, Amalesh
Abstract:: The seismic response of deep deposits of liquefiable and cyclic-softening susceptible soils has presented the geotechnical profession with significant engineering challenges. Strong ground motions may serve to soften soils under cyclic shear, trigger liquefaction, and produce damaging displacements as a consequence. This study improves the understanding of the in-situ, nonlinear,...

Geocaching: Perceptions of Impacts and Identity

Creator:: Fisher, Dianna M.
Abstract:: Geocaching is an outdoor recreational activity where participants (geocachers) utilize a handheld Global Positioning System (GPS) receiver or smartphone to download coordinates in order to navigate to the location of a hidden container, a geocache. Since its inception in 2000 geocaching has grown exponentially. The potential ecological and recreation management...

Development of Computational, Visualization, and Molecular Tools for Fungal and Oomycete Community Ecology

Creator:: Foster, Zachary Stephen Longiaru
Abstract:: Oomycetes are an important group of organisms with a variety of ecological roles similar to fungi. Although many are well-studied plant pathogens known for their devastating effects on agricultural systems, most are little-studied saprobes and parasites of plants and animals in nearly every ecosystem on earth. The advent of affordable...

From Microbes to Megafauna: The Ecology of Gut Microbiomes in Wild Herbivores

Creator:: Couch, Claire E.
Abstract:: All mammals host communities of commensal microbes in and on their bodies. Recent technological advances, combined with experimental studies in laboratory animals, are beginning to reveal the ubiquitous links between the gut microbiome and host disease, metabolism, immunity, and numerous other host functions. A new challenge of microbiome research is...
