Dogs, Death, and Dietary Breadth: Insights into the Macroecology and Macroevolution of Canidae

Creator:: Tanis, Brian P.
Abstract:: The size, shape, and stability of a species’ dietary niche can both influence and reflect a variety of biological patterns, including species interactions, extinction risk, and ecosystem function. This is particularly apparent when dietary changes manifest at ecosystem and clade scales to profoundly affect macroecological and macroevolutionary trajectories. However, many...

Linking Space, Time, and Elevation through Diet: Stable Isotope Analysis of Functionally Diverse Rodents in the Great Basin

Creator:: Taylor, David S.
Abstract:: Ecology is focused on understanding how organisms interact with each other and their environments, across ecological, spatial, and temporal scales. Thus, understanding how processes and patterns of ecological systems change across space and time is a principle goal for conservation biologist globally. While many approaches exist for investigating the changing...

How competitive are iconic competitors? Testing resource partitioning in Great Basin chipmunks

Creator:: Ormand, Elora J.
Abstract:: Competitive exclusion is a key concept in ecology describing the exclusion of one species by another from access to a limited resource. Competitive interactions between chipmunk species in the Great Basin, documented by James Brown in 1970, are often used as a textbook example of competitive exclusion. Whether competitive interactions...

Context and Scale Mediate the Impact of Climate on a Widespread Avian Predator

Creator:: Brawner, Michael D.
Abstract:: Anthropogenic climate change is threatening biodiversity as I currently understand it. There is now a large body of work highlighting species responses, globally, to this threat. Importantly, responses at the species level emerge from responses at lower levels of biological organization (individuals and populations) across a species’ geographic range. For...

Isotopic Analysis of Diet Specificity in the Chisel-toothed Kangaroo Rat, Dipodomys microps

Creator:: Guerre, Megan E.
Abstract:: Rapid changes in global climate have put many species at risk, particularly niche specialists. The Chisel-toothed kangaroo rat, Dipodomys microps, is thought to specialize on the desert shrub Atriplex confertifolia. Because of this close relationship, D. microps was presumed to have tracked the shrub as its distribution shifted south during...

The quantitative evaluation of radiological workplace indicators

Creator:: Brock, Terry A.
Abstract:: Two research studies at the U.S. Department of Energy's Hanford Site and Rocky Flats Environmental Technology Site (RFETS) explore the quantitative relationship between surface contamination, airborne radioactivity, worker intakes, and subsequent dose. In the first study, resuspension factors are developed and evaluated at the U.S. Department of Energy's (U.S. DOE)...

A comparison of deterministic and probabilistic radiation dose assessments at three fictitious ¹³⁷Cs contaminated sites in California, Colorado, and Florida

Creator:: Brock, Terry A.
Abstract:: Two methods of radiation dose assessment were evaluated for the Cs-137 in soil ⇒ leafy vegetable ⇒ human consumption exposure pathway at three fictitious contaminated sites in California, Colorado, and Florida. An annual dose equation was developed and per USEPA risk assessment guidelines, traditional, single point annual dose estimates were...

John Archibald Wheeler : a study of mentoring in modern physics

Creator:: Christensen, Terry M.
Abstract:: This dissertation has two objectives. The first objective is to determine where best to situate the study of mentoring (i.e. the 'making of scientists') on the landscape of the history of science and science studies. This task is accomplished by establishing mentoring studies as a link between the robust body...

Theoretical physics takes root in America : John Archibald Wheeler as student and mentor

Creator:: Christensen, Terry M.
Abstract:: John Archibald Wheeler (09 July 1911- ) is a familiar name to physicists and historians of physics alike. Among his many contributions to the corpus of knowledge, in 1939 John Wheeler and Niels Bohr co-authored the first paper on the generalized mechanism of nuclear fission. Beyond that seminal work, Wheeler...

Comparison of two microvalve designs fabricated in mild steel using microprojection welding and capacitive dissociation

Creator:: Terhaar, Tyson J.
Abstract:: Since the dawn of the computer age, there has been a push to create miniature devices. These devices were initially integrated circuit (IC) devices to perform calculations for computers. As the technology progressed, the scope of the devices diverged to included microelectromechanical (MEMS) devices, meaning that the devices perform mechanical...
