Lyme Disease Ecology In San Luis Obispo County: The Role Of The Western Gray Squirrel, Ryan William Baker-Branstetter
Lyme Disease Ecology In San Luis Obispo County: The Role Of The Western Gray Squirrel, Ryan William Baker-Branstetter
Master's Theses
Despite the fact that eight cases of Lyme disease were diagnosed in San Luis Obispo County between 2005-2013, the identity of wildlife hosts serving as sources for tick infection in this region remained unidentified. The primary cause of Lyme disease in the U.S. is the spirochetal bacterium Borrelia burgdorferi sensu stricto, and this agent had not been previously isolated from the region. Borrelia bissettii, a related species that has not been implicated as a common causative agent of Lyme disease, was isolated in small rodents inhabiting coastal scrub and chaparral habitats in a previous San Luis Obispo County study. However, …
Modeling Viscoelastic Behavior In Compact Bone Through A Distribution Of Collagen D-Spacing: A Finite Element Analysis, Christopher Ha
Modeling Viscoelastic Behavior In Compact Bone Through A Distribution Of Collagen D-Spacing: A Finite Element Analysis, Christopher Ha
Master's Theses
Osteoporosis affects nearly 54 million people in the United States. The cost associated with treatment is estimated to be $19 billion per year and is expected to grow yearly. D-spacing is the staggering of collagen molecules found at the nanoscopic level. Previously thought to have a constant value, recent studies have found that D-spacing has a distribution of values throughout the tissue. As part of an ongoing effort in understanding the mechanisms that are affected by osteoporosis, a finite element model was developed to explore the effects of D-spacing distribution on the viscoelastic material properties of bone tissue. The goal …

Maternal Smoking During Pregnancy And Offspring Birth Weight: A Genetically-Informed Approach Comparing Multiple Raters, Valerie S. Knopik, Kristine Marceau, Rohan H.C. Palmer, Taylor F. Smith, Andrew C. Heath
Maternal Smoking During Pregnancy And Offspring Birth Weight: A Genetically-Informed Approach Comparing Multiple Raters, Valerie S. Knopik, Kristine Marceau, Rohan H.C. Palmer, Taylor F. Smith, Andrew C. Heath
Psychology and Child Development
Maternal smoking during pregnancy (SDP) is a significant public health concern with adverse consequences to the health and well-being of the fetus. There is considerable debate about the best method of assessing SDP, including birth/medical records, timeline follow-back approaches, multiple reporters, and biological verification (e.g., cotinine). This is particularly salient for genetically-informed approaches where it is not always possible or practical to do a prospective study starting during the prenatal period when concurrent biological specimen samples can be collected with ease. In a sample of families (N = 173) specifically selected for sibling pairs discordant for prenatal smoking exposure, we: …
Complete Mitochondrial Genome Of The Speckled Dace Rhinichthys Osculus, A Widely Distributed Cyprinid Minnow Of Western North America, Samantha J. Bock, Morgan M. Malley, Sean Lema
Complete Mitochondrial Genome Of The Speckled Dace Rhinichthys Osculus, A Widely Distributed Cyprinid Minnow Of Western North America, Samantha J. Bock, Morgan M. Malley, Sean Lema
Biological Sciences
The speckled dace Rhinichthys osculus (order Cypriniformes), also known as the carpita pinta, is a small cyprinid minnow native to western North America. Here, we report the sequencing of the full mitochondrial genome (mitogenome) of R. osculus from a male fish collected from the Amargosa River Canyon in eastern California, USA. The assembled mitogenome is 16 658 base pair (bp) nucleotides, and encodes 13 protein-coding genes, and includes both a 12S and a 16S rRNA, 22 tRNAs, and a 985 bp D-loop control region. Mitogenome synteny reflects that of other Ostariophysian fishes with the majority of genes and RNAs encoded …
Two-Ply Channels For Faster Wicking In Paper-Based Microfluidic Devices, Conor K. Camplisson, Kevin M. Schilling, William L. Pedrotti, Howard A. Stone, Andres W. Martinez
Two-Ply Channels For Faster Wicking In Paper-Based Microfluidic Devices, Conor K. Camplisson, Kevin M. Schilling, William L. Pedrotti, Howard A. Stone, Andres W. Martinez
Chemistry and Biochemistry
This article describes the development of porous two-ply channels for paper-based microfluidic devices that wick fluids significantly faster than conventional, porous, single-ply channels. The two-ply channels were made by stacking two single-ply channels on top of each other and were fabricated entirely out of paper, wax and toner using two commercially available printers, a convection oven and a thermal laminator. The wicking in paper-based channels was studied and modeled using a modified Lucas–Washburn equation to account for the effect of evaporation, and a paper-based titration device incorporating two-ply channels was demonstrated.

Traversing Swanton Road, 21st Ed., James A. West
Traversing Swanton Road, 21st Ed., James A. West
Academic, Government & Associated Organizational Research Resources
Situated at the northwest end of Santa Cruz County and occupying circa 30 square miles of sharply contrasted terrain, the Scott Creek Watershed concentrates within its geomorphological boundaries, at least 10-12% of California's flora, both native and introduced. Paradoxically, the use/abuse that the watershed has sustained over the past 140+ years, has not necessarily diminished the biodiversity and perhaps parallels the naturally disruptive but biologically energizing processes (fire, flooding, landslides and erosion), which have also been historically documented for the area for +60 years. This is an early edition of an extensive document by James A. West. Please visit the …

Mapping The Movement Of Overwintering Western Monarch Butterflies (Danaus Plexippus) At The Pismo Beach Monarch Butterfly Grove Using Arcgis Software, Brett Johnson, Jesse Wycko, Daniel Goldthwaite, Tyler Brown
Mapping The Movement Of Overwintering Western Monarch Butterflies (Danaus Plexippus) At The Pismo Beach Monarch Butterfly Grove Using Arcgis Software, Brett Johnson, Jesse Wycko, Daniel Goldthwaite, Tyler Brown
Symposium
Dr. Villablanca of the Cal Poly Biology Department commissioned this project with the goal of tracking Monarch Butterfly spatial redistribution in anticipation of or response to severe weather events. We believe that Monarchs cluster non-preferentially on introduced Eucalyptus trees until midwinter when they begin to cluster preferentially on native conifers. Based on the efforts of a previous group of students, it has been deter- mined that, over a two-week time period in mid-winter, Monarchs spend the majority of their time on native conifers. We set out to clearly demonstrate Monarch Butterfly spatial redistribution in either anticipation of or response to …
Variation In Microbiome Composition And Stability For A Vancomycin Treated Primary Sclerosing Cholangitis Patient With Ulcerative Colitis Compared With Controls, Alanna Dubrovsky
Variation In Microbiome Composition And Stability For A Vancomycin Treated Primary Sclerosing Cholangitis Patient With Ulcerative Colitis Compared With Controls, Alanna Dubrovsky
Symposium
The bacterial composition of the human intestines contributes to much more than just digestion. In the inflammatory, autoimmune conditions primary sclerosing cholangitis (PSC) and ulcerative colitis (UC), the microbiome may be, in some cases, a factor. To gain a better understanding of the composition and stability of the microbiome in a patient treated with vancomycin for PSC, terminal restriction fragment (TRF) analysis was performed on 13 controls and 1 patient, and 16s rRNA microbiome composition analysis was performed on 1 patient and 3 controls. Results showed similar levels of stability, with surprising differences in composition.
The Influence Of Psychological Factors On Reducing Recovery Time From Total Knee Replacement Surgery, Melissa Geiger
The Influence Of Psychological Factors On Reducing Recovery Time From Total Knee Replacement Surgery, Melissa Geiger
Symposium
Osteoarthritis is the most common cause of physical disability that Americans face, leading to destruction of the joints of the body. The primary joint affected is the knee, and the leading treatment is total knee replacement. The incidence of total knee replacement surgery is rising–and will continue to rise–as a treatment for knee pain resulting from osteoarthritis (Mizner et al., 2005). Various psychological factors have been proven to influence a person’s well-being in general and, more specifically, with recovery from illness or surgery (Taylor, 2011). Pre- surgical psychological screenings are an important factor in determining how the patient will recover …
Observational Learning In Eusocial Insects: Chemical Transmission Of Information Between Rival Colonies Of Leafcutter Ants, Avity Norman
Observational Learning In Eusocial Insects: Chemical Transmission Of Information Between Rival Colonies Of Leafcutter Ants, Avity Norman
Symposium
Like other ants (Hymenoptera, Formicidae), leafcutter ants of the genus Atta use chemical signals, including airborne pheromones and cuticular hydrocarbons, to coordinate extraordinarily complex eusocial organization. This genus is ecologically and economically important because of its extreme impact on vegetation throughout the Neotropics, and also lends itself well to ethological research because of its easily observed and manipulated foraging behavior. Saverschek et al. (2010) used fungicide-treated leaves to induce an avoidance response to certain types of leaves, demonstrating that colonies of Atta columbica are capable of experiential learning and long-term memory. The proposed study will use similar methods to determine …
Protocols For Cleaning And Articulating Large Mammal Skeleton, Brandon Rowley
Protocols For Cleaning And Articulating Large Mammal Skeleton, Brandon Rowley
Symposium
This protocol will refer to Panthera tigris as an example for each cleaning method and articulation because that was the organism subject to this procedure. However, the processes and methods discussed here can be used as reference for any large mammal. The key is to make sure the skeleton is clean, which entails removing the meat from the bones, degreasing, and whitening. Once this is done, articulation can begin. The protocol is divided into three major sections: cleaning the skeleton, whitening and degreasing, and articulation. The cleaning section contains three contemporary methods for removing tissue. Each method can be performed …
Size And Abundance Of Pismo Clams In The Intertidal And Subtidal, Jenny Greene
Size And Abundance Of Pismo Clams In The Intertidal And Subtidal, Jenny Greene
Symposium
Pismo clams, Tivela stultorum, were observed at Rincon Beach, CA to find patterns of abundance and size distribution along a depth gradient from the intertidal, where recreational clammers have access on foot, to the subtidal, where clammers only have access with more specialized snorkeling or SCUBA equipment. Size and abundance patterns were compared between the intertidal and subtidal regions. A heuristic model was created to predict the effects of predation and wave action on clam density. Clam abundance was significantly greater in the intertidal than the subtidal and displayed a Gaussian distribution across the entire distance sampled. While Pismo clam …

An Invasive Grass And A Desert Adapted Rodent: Is There An Effect On Locomotory Performance And Is It Modified By Prior Experience Or Familiarization?, Camille D. Boag
An Invasive Grass And A Desert Adapted Rodent: Is There An Effect On Locomotory Performance And Is It Modified By Prior Experience Or Familiarization?, Camille D. Boag
Master's Theses
Kangaroo rats (Dipodomys spp.) are frequently characterized as keystone species for their role in altering soil characteristics, changing habitat structure through seed consumption and dispersal, and being important primary consumers in their ecosystem. They are arid adapted and known to forage in areas with sparse vegetation. Studies suggests densely vegetated habitat to be unsuitable for kangaroo rats because plants are an impediment to their locomotion and predator avoidance behaviors. This study focuses on an invasive grass, South African Veldt (Ehrharta calycina), that converts landscapes with sparse vegetation into dense grassland habitats, and the Lompoc kangaroo rat …
Effects Of Supplemental Hydration On Physiology And Behavior Of Northern Pacific Rattlesnakes (Crotalus Oreganus Oreganus), Griffin D. Capehart
Effects Of Supplemental Hydration On Physiology And Behavior Of Northern Pacific Rattlesnakes (Crotalus Oreganus Oreganus), Griffin D. Capehart
Master's Theses
Hydration is a critical element for many physiological processes in vertebrates, such as protein production, innate immunity, and behavioral processes such as daily activity and thermoregulation. Few studies have directly assessed the effect of hydration on these animals in nature. While it seems intuitive that drought is stressful to animals, studies examining drought are typically observational and fail to assess how the hydration state of these animals influences their physiology and behavior. We tested for an effect of hydration on several physiological and behavioral parameters in Northern Pacific rattlesnakes (Crotalus oreganus oreganus) by experimentally manipulating hydration levels in …
Wild-But-Not-Too-Wild Animals: Challenging Goldilocks Standards In Rewilding, Erica Von Essen, Michael P. Allen
Wild-But-Not-Too-Wild Animals: Challenging Goldilocks Standards In Rewilding, Erica Von Essen, Michael P. Allen
Between the Species
Rewilding is positioned as ‘post’-conservation through its emphasis on unleashing the autonomy of natural processes. In this paper, we argue that the autonomy of nature rhetoric in rewilding is challenged by human interventions. Instead of joining critique toward the ‘managed wilderness’ approach of rewilding, however, we examine the injustices this entails for keystone species. Reintroduction case studies demonstrate how arbitrary standards for wildness are imposed on these animals as they do their assigned duty to rehabilitate ecosystems. These ‘Goldilocks’ standards are predicated on aesthetic values that sanction interventions inconsistent with the premise of animal sovereignty. These include culling, relocations and …

Temperatures Experienced By Fresh-Cut Leafy Greens During Retail Storage And Display, W. Brown, E. Ryser, L. Gorman, Scott J. Steinmaus, Keith Vorst
Biological Sciences
There has been limited published work in the United States on temperature profiling of fresh-cut, bagged leafy greens during their transport, retail storage, and retail display. This study utilized temperature monitors placed in backrooms and display cases at nine supermarkets located in southern California: the Central Coast (Santa Barbara to Los Osos), Greater Los Angeles (Burbank area), and Greater Palm Desert. Sensors were installed midway along each 8-foot display case section containing fresh-cut leafy greens. Monitors were placed at the front and back of shelves and in the lower bin. In storage rooms, sensors were placed 4 feet from the …
Implications Of Variable Waste Placement Conditions For Msw Landfills, Jason T. Cox, Nazli Yesiller, James L. Hanson
Implications Of Variable Waste Placement Conditions For Msw Landfills, Jason T. Cox, Nazli Yesiller, James L. Hanson
Civil and Environmental Engineering
This investigation was conducted to evaluate the influence of waste placement practices on the engineering response of municipal solid waste (MSW) landfills. Waste placement conditions were varied by moisture addition to the wastes at the time of disposal. Tests were conducted at a California landfill in test plots (residential component of incoming wastes) and full-scale active face (all incoming wastes including residential, commercial, and self-delivered components). The short-term effects of moisture addition were assessed by investigating compaction characteristics and moisture distribution and the long-term effects by estimating settlement characteristics of the variably placed wastes. In addition, effects on engineering properties …

Characterization Of Electrophorectic Separations On A Cellulose Paper-Microfluidic Chip, Kyle Robert Fast
Master's Theses
The purpose of this thesis project is to demonstrate the ability to utilize electrophoresis in a cellulose paper microfluidic chip to manipulate charged particles. Materials were selected and a manufacturing protocol was created to successfully apply the electric field onto the paper chip. Experiments were performed to characterize the separation rates for charged, colorimetric dye, Orange G in the membrane as a function of an applied electric field, dye concentration, and distance traveled. The experiments confirmed that the electric field can be applied to the chip and particle separation rates were characterized. Next, the determined rates results were used to …
Demographics And Transfer Of Escherichia Coli Within Bos Taurus Populations, Joshua Ryan Dillard
Demographics And Transfer Of Escherichia Coli Within Bos Taurus Populations, Joshua Ryan Dillard
Master's Theses
In the United States, symptoms caused by pathogenic strains of Escherichia coli are on the rise. A major source of these pathogenic strains is the E. coli in the digestive tract of cattle. The purpose of this project was to determine if E. coli are transferred between individuals of the same species and if interspecies transmission is possible. Proximity of cattle was also studied as a contributing factor to the transfer of E. coli. To accomplish this goal, E. coli isolates from cattle and cohabitating ground squirrels were compared through a new method of bacterial strain typing called pyroprinting. …
Effects Of Testosterone On The Spatial Ecology, Coloration, And Brain Regions In Western Fence Lizards, Sceloporus Occidentalis, Rachel Catharine Wilson
Effects Of Testosterone On The Spatial Ecology, Coloration, And Brain Regions In Western Fence Lizards, Sceloporus Occidentalis, Rachel Catharine Wilson
Master's Theses
An organism’s spatial ecology allows for access to essential resources such as food, mates, and escape from predators. Home range size, or the total area an organism inhabits, varies in relation to numerous factors including seasonality. During the breeding season, home range size increases in males across taxa. In addition, males usually also have larger home range sizes than females. This implicates testosterone (T) as a possible mediator of this relationship. Indeed, T causes an increase in home range size of males in numerous species of lizards. In addition to T causing an increase in home range size, it also …
