Mechanisms Of Elastic Enhancement And Hindrance For Finite-Length Undulatory Swimmers In Viscoelastic Fluids, Becca Thomases, Robert D. Guy

Mathematics Sciences: Faculty Publications

A computational model of finite-length undulatory swimmers is used to examine the physical origin of the effect of elasticity on swimming speed. We explore two distinct target swimming strokes: one derived from the motion of Caenorhabditis elegans, with large head undulations, and a contrasting stroke with large tail undulations. We show that both favorable stroke asymmetry and swimmer elasticity contribute to a speed-up, but a substantial boost results only when these two effects work together. We reproduce conflicting results from the literature simply by changing relevant physical parameters.

Closing The Health Disparities Gap Between African American Mothers And Infants And Their Racial And Ethnic Counterparts In Correspondence With The Santa Clara County’S Black Infant Health Program, Hannah Wikkeling

Master's Projects and Capstones

Health disparities and inequities that affect the African American (includes those who consider themselves of African descent and/or Black individuals) women and their babies appear to be less dependent upon age, economic status, or education, as once considered previously. Further, it was thought that the prevalence of diseases and ill health were only attributed to poverty, lack of education/resources and social support. However, although these factors can cause the pervasiveness of disease, there are larger forces at play. Even when African American women have a pregnancy at an optimal age, are well educated, and have adequate income, poor birth outcomes …

Acute Effects Of Tio2 Nanomaterials On The Viability And Taxonomic Composition Of Aquatic Bacterial Communities Assessed Via High-Throughput Screening And Next Generation Sequencing, Binh Chu, Tiezheng Tong, Jean-François Gaillard, Kimberley A. Gray, John J. Kelly

Biology: Faculty Publications and Other Works

The nanotechnology industry is growing rapidly, leading to concerns about the potential ecological consequences of the release of engineered nanomaterials (ENMs) to the environment. One challenge of assessing the ecological risks of ENMs is the incredible diversity of ENMs currently available and the rapid pace at which new ENMs are being developed. High-throughput screening (HTS) is a popular approach to assessing ENM cytotoxicity that offers the opportunity to rapidly test in parallel a wide range of ENMs at multiple concentrations. However, current HTS approaches generally test one cell type at a time, which limits their ability to predict responses of …

Pygmy Rabbit (Brachylagus Idahoensis) Habitat Selection: Does Sagebrush (Artemisia Sp.) Age Influence Selection?, Robert J. Edgel, Janet L. Pierce, Randy T. Larsen

Western North American Naturalist

The pygmy rabbit (Brachylagus idahoensis) is a sagebrush (Artemisia spp.) obligate that depends on sagebrush habitats for food and cover throughout its life cycle. Invasive species, frequent fires, overgrazing, conversion of land to agriculture, energy development, and many other factors have contributed to recent declines in both quantity and quality of sagebrush habitats required by pygmy rabbits. Given declining availability of sagebrush, there is a need to identify characteristics of suitable pygmy rabbit habitat. Although habitat selection information exists from several western states, data is limited for pygmy rabbits in Utah at the extent of …

Survey Of Chironomidae (Insecta: Diptera) From The Kuskokwim River Watershed In Western Alaska, Barbara L. Hayford, Robert L. Newell, Zach J. Crete

Western North American Naturalist

Rapidly declining diversity of freshwater species necessitates surveys to document and describe patterns in biodiversity. To this end, a survey of Chironomidae (Insecta: Diptera) was conducted in a remote watershed of western Alaska. Larval chironomids were collected from 16 stream sites in the Kuskokwim River watershed in 2009 and 2010. Twenty-seven chironomid taxa were identified. Orthocladiinae was the most diverse subfamily and was numerically dominant at all sites except a glacial runoff stream where Diamesinae was numerically dominant. Two rare chironomids were collected in the study: an undescribed species of Stilocladius and a species ofOrthocladius (Mesorthocladius). The …

An Observation Of Apparent Teaching Behavior In The Pallid Bat, Antrozous Pallidus, Jessie P. Bunkley, Jesse R. Barber

Western North American Naturalist

During a laboratory study of pallid bat (Antrozous pallidus) hunting behavior, we observed an interaction wherein an adult female appeared to aid a juvenile male in learning a novel foraging task. This single observation adheres to the 3 requirements of teaching outlined by Caro and Hauser (1992). A female bat experienced with a hunting task modified her behavior in the presence of a naïve observing male, resulting in a cost of reduced food availability to the female when she was hungry, while directing the male to food resources and accelerating his learning of a foraging task. The experienced …

Pl-Patchsurfer: A Novel Molecular Local Surface-Based Method For Exploring Protein-Ligand Interactions, Bingjie Hu, Xiaolei Zhu, Lyman Monroe, Mark G. Bures, Daisuke Kihara

Department of Biological Sciences Faculty Publications

Structure-based computational methods have been widely used in exploring protein-ligand interactions, including predicting the binding ligands of a given protein based on their structural complementarity. Compared to other protein and ligand representations, the advantages of a surface representation include reduced sensitivity to subtle changes in the pocket and ligand conformation and fast search speed. Here we developed a novel method named PL-PatchSurfer (Protein-Ligand PatchSurfer). PL-PatchSurfer represents the protein binding pocket and the ligand molecular surface as a combination of segmented surface patches. Each patch is characterized by its geometrical shape and the electrostatic potential, which are represented using the 3D …

Pupil Dilation Dynamics Track Attention To High-Level Information, Olivia E. Kang, Katherine E. Huffer, Thalia P. Wheatley

Dartmouth Scholarship

It has long been thought that the eyes index the inner workings of the mind. Consistent with this intuition, empirical research has demonstrated that pupils dilate as a consequence of attentional effort. Recently, Smallwood et al. (2011) demonstrated that pupil dilations not only provide an index of overall attentional effort, but are time-locked to stimulus changes during attention (but not during mind-wandering). This finding suggests that pupil dilations afford a dynamic readout of conscious information processing. However, because stimulus onsets in their study involved shifts in luminance as well as information, they could not determine whether this coupling of stimulus …

Threatening Others : Nicaraguans And The Formation Of National Identities In Costa Rica, Carlos Sandoval-Garcia

Ohio University Press Open Access Books

During the last two decades, a decline in public investment has undermined some of the national values and institutions of Costa Rica. The resulting sense of dislocation and loss is usually projected onto Nicaraguan “immigrants.”
Threatening Others: Nicaraguans and the Formation of National Identities in Costa Rica explores the representation of the Nicaraguan “other” in the Costa Rican imagery. It also seeks to address more generally why the sense of national belonging constitutes a crucial identification in contemporary societies. Interdisciplinary and based on extensive fieldwork, it looks critically at the “exceptionalism” that Costa Ricans take for granted and view as …

Trauma Informed Practices For Oakland Unite Service Providers, Maereg D. Haile

Master's Projects and Capstones

Oakland, California - a home to almost 400,000 residents - is the top five most violent cities of the nation. There are lots of factors that greatly contribute to violence including: Poverty, housing/homelessness, unemployment, food insecurity, educational attainment, substance abuse. These factors feed to greater healthy disparities and increased trauma in low-income communities – specifically in east and west Oakland. Measure Y, now called Oakland Unite, is the current violence prevention effort that is set for reauthorization in November 2014. In order for these efforts to continue, Oakland Unite has started looking at comprehensive violence prevention initiatives that includes mental …

Prevention Of Hiv Mother-To-Child-Transmission In Sub-Saharan Africa, Sidik Abdul-Mumuni

Master's Projects and Capstones

The transmission of HIV infection from an HIV-positive mother to her child during labor, pregnancy, breastfeeding or delivery is termed as mother-to-child HIV transmission (WHO, 2013 report on HIV). A range of 15-45% infection transmissions are possible when no intervention strategies are put into place. Globally, goals and initiatives have been set to combat this issue as well as speeding up the interventions and achieve possible transmission rates of levels less than 5% and total elimination of new infant HIV infections by 2015 (WHO, 2013 report on HIV). In 2011, 57% of pregnant women living with HIV in low and …

Pinyon Pine Mortality Alters Communities Of Ground-Dwelling Arthropods, Robert J. Delph, Michael J. Clifford, Neil S. Cobb, Paulette L. Ford, Sandra L. Brantley

Western North American Naturalist

We documented the effect of drought-induced mortality of pinyon pine (Pinus edulisEngelm.) on communities of ground-dwelling arthropods. Tree mortality alters microhabitats utilized by ground-dwelling arthropods by increasing solar radiation, dead woody debris, and understory vegetation. Our major objectives were to determine (1) whether there were changes in community composition, species richness, and abundance of ground-dwelling arthropods associated with pinyon mortality and (2) whether specific habitat characteristics and microhabitats accounted for these changes. We predicted shifts in community composition and increases in arthropod diversity and abundance due to the presumed increased complexity of microhabitats from both standing dead and …

Habitat Suitability As A Limiting Factor For Establishment In A Narrow Endemic: Abronia Alpina (Nyctaginaceae), Meredith D. Jabis, Tina J. Ayers

Western North American Naturalist

Understanding the causes of narrow endemism is crucial to conservation, particularly in biodiversity hotspots like the California Floristic Province. The loss of rare species as a consequence of climate change could result in substantial reductions in biodiversity, especially in high-elevation systems. We investigated causes of range restriction by using the narrow alpine endemic Abronia alpina (Ramshaw Meadows sand verbena) as a case study. This study examined habitat suitability as a limiting factor for the establishment of Abronia alpina, an endemic native to only 2 meadow systems in the Sierra Nevada Mountains, Inyo National Forest, California, USA. We tested habitat suitability …

Western North American Naturalist

Merriam’s Wild Turkeys (Meleagris gallopavo merriami) is a species of interest for managers and is considered economically valuable through wildlife viewing and hunting. We captured, radio-marked, and monitored 49 turkeys (27 males, 22 females) over a 3-year period (2008–2011) in the Valles Caldera National Preserve, Jemez Mountains, New Mexico. Annual Kaplan–Meier survival estimates varied among years (range 0.33–0.80). Lowest seasonal survival of 0.42 (SE 0.14) occurred during winter 2010 (1 Dec 2009–31 Mar 2010). We observed 20 fatalities of the 49 monitored turkeys. Predation by bobcats (Lynx rufus) and pumas (Puma concolor) accounted for …

Roost And Forage Site Fidelity Of Western Small-Footed Myotis (Myotis Ciliolabrum) In An Oregon Desert Canyon, Thomas J. Rodhouse, Kenneth J. Hyde

Western North American Naturalist

We describe the roosting and foraging behavior patterns of western small-footed myotis (Myotis ciliolabrum) observed during a vertebrate inventory of the John Day Fossil Beds National Monument in north central Oregon. We used radiotelemetry to track 9 adult females, including 3 lactating and 6 postlactating bats, during July–September 2003. We found that these bats showed considerable fidelity to a common foraging area at the confluence of the John Day River and a tributary creek along which bats commuted and roosted. Individual bats did not roost together, but each showed high fidelity to local clusters of rock outcrops in …
