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...

Sex-based differences in anti-predator response of crickets to chemical cues of a mammalian predator

Creator:: Tanis, Brian P., Bott, Bradley, and Gaston, Brian J.
Abstract:: Anti-predator behaviors like vigilance or hiding come at the expense of other fitness increasing behaviors such as foraging. To compensate for this trade-off, prey assess predation risk and modify the frequency of anti-predator behaviors according to the likelihood of the threat. In this study, we tested the ability of house...

Dental microwear textures across cheek teeth in canids: Implications for dietary studies of extant and extinct canids

Creator:: Tanis, Brian P., DeSantis, Larisa R. G., and Terry, Rebecca C.
Abstract:: Dental microwear texture analysis (DMTA) has been instrumental in reconstructing dietary ecology of extinct and extant carnivorans. Current sampling methods for canids focus on lower second molars (m2), where the grinding of flesh and bone captures dental microwear indicative of diet. However, dental microwear on other biomechanically analogous grinding facets...

Mahler's order functions and algebraic approximation of p-adic numbers

Creator:: Dietel, Brian Christopher
Abstract:: If P is an integer polynomial denote the degree of P by ∂(P) and let H(P) be the maximum of the absolute value of the coefficients of P. Define Λ(P)=2[superscript ∂(P)]H(P) and for a fixed prime p let C[subscript p] denote the completion of the algebraic closure of the p-adic...

Stags of the Sea or Hedgehogs of the Harbor? Inferring the Point of Sculpin Cranial Weaponry

Creator:: Buser, Thaddaeus J.
Abstract:: Animal weapons are thought to have evolved to compete for reproductive opportunities within a species. Across the diverse weapon-bearing taxa, several evolutionary trends have emerged: (1) increasing complexity and relative size across ontogeny, (2) sexual dimorphism, and (3) higher levels of random deviations from symmetry (i.e., fluctuating asymmetry) than non-weaponized...

Genetic and morphological evidence suggests cryptic speciation within the Torrent Sculpin, Cottus rhotheus, across the Pacific Northwest

Creator:: Nicholas, Benjamin P.
Abstract:: Dwelling on the bottom of large rivers to high alpine streams, freshwater sculpins (genus Cottus) occur in high densities across the Pacific Northwest, with 21 currently recognized species found in the Pacific Northwest. Sculpin fill many ecological roles, with some species serving as important prey sources, and others competing with...

Crossing Boundaries during Stress Responses: Antigen Presentation by Adaptive and Innate MHC Class I Molecules

Creator:: Nagamine, Brandy S.
Abstract:: The immune system is a complex network of cellular processes working in harmony to guard us against pathogenic attack. Of utmost importance is the ability of the immune system to discriminate between “self” and “non-self” and diseased versus healthy. Recognition of antigens complexed to major histocompatibility complex (MHC) molecules is...

Non-Canonical Nedd8 Conjugation Mediated Targeted Protein Degradation and Direct Antigen Presentation

Creator:: Vijayasimha, Kartikeya
Abstract:: While the role of ubiquitin in protein degradation is well established, the role of other ubiquitin-like proteins (UBLs) in protein degradation is less clear. Neural precursor cell expressed developmentally down-regulated protein 8 (NEDD8) is the UBL with the highest level of amino acid identity when compared to ubiquitin. Here we...

Steady-State Diffusion in a Spatially Varying Porous Medium

Creator:: Ferrero, Peter T.
Abstract:: Heterogeneous porous material represents a persistent challenge in the field of engineering. Microscale properties such as the porosity and microchannel torturosity significantly control the macroscale transport characteristics of homogeneous porous medium. Additional complexity is introduced when these small-scale features vary in space. Examples of heterogeneous porous systems include artificial body...
