Aerodynamics, Kinematics, And Ecology Of Slow Flight In Birds, Kristen Elizabeth Crandell

Graduate Student Theses, Dissertations, & Professional Papers

The overarching goal of my dissertation is to elucidate the force production mechanisms of slow flight in birds. Slow flight is extremely energetically costly per unit time, yet highly important for takeoff and survival in birds. However, at slow speeds it is presently thought that most birds do not produce beneficial aerodynamic forces during the entire wingbeat: instead, they fold or flex their wings during upstroke, prompting the long-standing prediction that the upstroke produces trivial forces. Here, I examined the kinematics, aerodynamics, skeletal drivers, and potential ecological influences of force production in flight. In chapter one, I establish that wings …

Does Migration Matter? Causes And Consequences Of Migratory Behavior In Sierra Nevada Bighorn Sheep, Derek Benjamin Spitz

Graduate Student Theses, Dissertations, & Professional Papers

Despite their potential conservation importance, the demographic implications of migratory behavior remain poorly understood. Sierra Nevada bighorn sheep (Ovis canadensis sierrae; hereafter “Sierra bighorn”) are federally-endangered and partially migratory. In summer, Sierra bighorn share high-elevation summer ranges, but in winter some individuals migrate to lower elevation for winter while others remain resident at high-elevation. Lower elevations have better forage in winter, but these areas also carry an increased risk of predation from Sierra bighorn's primary predator, the cougar (Puma concolor). We should therefore expect differences in winter conditions to result in demographic differences between migrants and residents.

First, I developed …

Groups And Mortality: Their Effects On Cooperative Behavior And Population Growth In A Social Carnivore, David E. Ausband

Graduate Student Theses, Dissertations, & Professional Papers

Cooperative breeding refers to the cooperative care of related, or even unrelated, young. Helpers can increase the survival or reproduction of the breeders in the group which increases helper fitness indirectly. We have a poor understanding of how mortality, particularly human harvest, affects cooperative breeders. Given their complex social structures, territorial defense that relies on group size, and persistent harvest regimes, gray wolves (Canis lupus) are an ideal species for studying the ecological relationships between mortality, group size and composition, and population growth in a cooperative breeder.

Chapter 1: How does group size affect vital rates of individuals and population …

Cultural And Ecological Relationship Between The Nisqually Indian Tribe And Plants Of Mount Rainier National Park, David Alan Hooper

Graduate Student Theses, Dissertations, & Professional Papers

Throughout the history of the National Park Service, the question of whether Native AmericanÆs still have rights to traditionally used natural resources found within park lands has been debated. This debate is largely held in political, legal, and philosophical arenas, but there are ethnographic and ecological questions that need to be addressed in order for policy makers to make informed decisions. Addressing these questions also provides insight into how cultures develop sustainable harvesting practices. One of the parks that has been addressing traditional plant harvesting is Mount Rainier National Park, which has been working with the Nisqually Indian Tribe to …

Why Did The Bear Cross The Road? Comparing The Performance Of Multiple Resistance Surfaces And Connectivity Modeling Methods, Samuel A. Cushman, Jesse S. Lewis, Erin Landguth

Biological Sciences Faculty Publications

There have been few assessments of the performance of alternative resistance surfaces, and little is known about how connectivity modeling approaches differ in their ability to predict organism movements. In this paper, we evaluate the performance of four connectivity modeling approaches applied to two resistance surfaces in predicting the locations of highway crossings by American black bears in the northern Rocky Mountains, USA. We found that a resistance surface derived directly from movement data greatly outperformed a resistance surface produced from analysis of genetic differentiation, despite their heuristic similarities. Our analysis also suggested differences in the performance of different connectivity …

Nmp-7 Inhibits Chronic Inflammatory And Neuropathic Pain Via Block Of Cab3.2 T-Type Calcium Channels And Activation Of Cb2 Receptors, N. Daniel Berger, Vinicius M. Gadotti, Ravil R. Petrov, Kevin Chapman, Philippe Diaz, Gerald W. Zamponi

Biological Sciences Faculty Publications

Background: T-type calcium channels and cannabinoid receptors are known to play important roles in chronic pain, making them attractive therapeutic targets. We recently reported on the design, synthesis and analgesic properties of a novel T-type channel inhibitor (NMP-7), which also shows mixed agonist activity on CB₁ and CB₂ receptors in vitro. Here, we analyzed the analgesic effect of systemically delivered NMP-7 (intraperitoneal (i.p.) or intragstric (i.g.) routes) on mechanical hypersensitivity in inflammatory pain induced by Complete Freund’s Adjuvant (CFA) and neuropathic pain induced by sciatic nerve injury.

Results: NMP-7 delivered by either i.p. or i.g. routes produced …

A Regional Look At Hanpp: Human Consumption Is Increasing, Npp Is Not, Steven W. Running

Ecosystem and Conservation Sciences Faculty Publications

Abdi et al (2014 Environ. Res. Lett. 9 094003), have adapted the concept of comparing supply and demand of annual plant production known as human appropriation of net primary production (HANPP) to a region of the Sahel with rapid population growth. They found that HANPP more than doubled over the study period of 2000–2010, from 19% to 41%, suggesting increasing vulnerability of these populations to food insecurity.

Using Multi-Compartment Ensemble Modeling As An Investigative Tool Of Spatially Distributed Biophysical Balances: Application To Hippocampal Oriens-Lacunosum/Moleculare (O-Lm) Cellns, Vladislav Sekulic, J. Josh Lawrence, Frances K. Skinner

Biomedical and Pharmaceutical Sciences Faculty Publications

Multi-compartmental models of neurons provide insight into the complex, integrative properties of dendrites. Because it is not feasible to experimentally determine the exact density and kinetics of each channel type in every neuronal compartment, an essential goal in developing models is to help characterize these properties. To address biological variability inherent in a given neuronal type, there has been a shift away from using hand-tuned models towards using ensembles or populations of models. In collectively capturing a neuron’s output, ensemble modeling approaches uncover important conductance balances that control neuronal dynamics. However, conductances are never entirely known for a given neuron …

Astrocyte-Specific Regulation Of Hmecp2 Expression In Drosophila, David Hess-Homeier, Chia-Yu Fan, Tarun Gupta, Ann-Shyn Chiang, Sarah J. Certel

Biological Sciences Faculty Publications

Alterations in the expression of Methyl-CpG-binding protein 2 (MeCP2) either by mutations or gene duplication leads to a wide spectrum of neurodevelopmental disorders including Rett Syndrome and MeCP2 duplication disorder. Common features of Rett Syndrome (RTT), MeCP2 duplication disorder, and neuropsychiatric disorders indicate that even moderate changes in MeCP2 protein levels result in functional and structural cell abnormalities. In this study, we investigated two areas of MeCP2 pathophysiology using Drosophila as a model system: the effects of MeCP2 glial gain-of-function activity on circuits controlling sleep behavior, and the cell-type specific regulation of MeCP2 expression. In this study, we first examined …
