Relationship Of Maternal Flow Environment To Offspring Size In Botrylloides Violaceus, Damion J. Delton, Sarah Cohen

STAR Program Research Presentations

Colonial botryllid tunicates, such as Botrylloides violaceus, brood large, non-feeding offspring with extremely limited larval life spans of minutes to perhaps one day. Despite the importance of this transitory life history stage, there is little information on how environmental factors such as ambient water flow affect larval size among invertebrates. Since adult tunicates feed by filtering particles from the water flowing around the siphons, we reasoned that colonies of B. violaceus in high water flow may produce larger offspring due to greater food availability. We tested to see whether there was a relationship between larval size and water motion in …

Tunicate Recruitment In A Temperature Fouling Community, Garrett Benjamin, Sarah Cohen

STAR Program Research Presentations

Settlement among native and invasive tunicates in fouling communities were observed at weekly intervals at the Pillar Point Harbor at Half Moon Bay, California. Our hypothesis is that because tunicates are filter feeding organisms, their settling reates will be dependant on flow rates. Settlement plates and plaster dissolution module plates (Clods) were used to quantify flow and settlement variations weekly for one summer month using high resolution field microscopy. Three genera of colonial tunicates (Botrylloides sp., Didemnum vexillum and Distaplia sp.) along with two solitary tunicates Ascidia sp., Cionia sp. and a bryozoan Watersipora sp. were quantified in …

Addressing Biased Occurrence Data In Predicting Potential Sierra Nevada Red Fox Habitat For Survey Prioritization, Casey Cleve, John D. Perrine, Barbara Holzman, Ellen Hines

Biological Sciences

The Sierra Nevada red fox Vulpes vulpes necator is listed as a threatened species under the California Endangered Species Act. It originally occurred throughout California’s Cascade and Sierra Nevada mountain regions. Its current distribution is unknown but should be determined in order to guide management actions. We used occurrence data from the only known population, in the Lassen Peak region of northern California, combined with climatic and remotely sensed variables, to predict the species’ potential distribution throughout its historic range. These model predictions can guide future surveys to locate additional fox populations. Moreover, they allow us to compare the relative …

Thermal Destruction Of Geobacillus Stearothermophilus In Rendered Animal Co-Products, Yubo Zhang

All Theses

The non-pathogenic, heat stabile organism Geobacillus stearothermophilus was used during thermal death time testing of rendered poultry materials from three different rendering plants. G. stearothermophilus is an endospore–forming, Gram positive, thermophilic bacterium that is commonly used in the canning industry. A modification of the method of Kim and Naylor (1966) was used to prepare a G. stearothermophilus spore suspension. Uninoculated and inoculated rendering samples containing 50% fat and rendered crax were prepared. Lecithin and 2,3,5–triphenyl–2H–tetrazolium chloride (TTC) were used during sample enumeration to emulsify the high fat samples and to aid in detection of colonies, respectively. Commercial rendering cookers are …

Climate And Vegetation Change In The Newberry Mountains, Southern Clark County, Nevada, Ross Joseph Guida

UNLV Theses, Dissertations, Professional Papers, and Capstones

Ecological studies have shown worldwide that vegetation is being affected by climate change. Species are shifting to new elevations and physiographic positions to adapt to changes in their environment. More specifically, paleoecology studies in the Mojave Desert have shown shifting vegetation patterns in response to past warming and precipitation changes. Recent studies have shown mortality among desert plants related to extended drought and warming. However, few studies have shown how the geographic distribution of Mojave Desert species has changed during this most recent period of warming. This study addresses this gap in the literature by focusing on several plant species …

Glacier Change, Concentration, And Elevation Effects In The Karakoram Himalaya, Upper Indus Basin, Kenneth Hewitt

Geography and Environmental Studies Faculty Publications

In recent decades the consequences of climate change for Himalayan glaciers has become of great concern. Glaciers in much of High Asia appear to be declining, some at globally extreme rates (Ageta 2001;Oerlemanns 2001). It had been widely reported that the Indus basin is threatened with severe losses. However, emerging evidence suggests that such reports were, at best, exaggerated (Raina 2009;Armstrong 2010).

Several inquiries have concluded that the behavior of Karakoram glaciers differs from those in the rest of the Himalaya and from the more intensively studied European and North American glaciers (Mayewski and Jeschke 1979; Kick 1989; Shroder et …

Raman Spectroscopic Study Of Solid Solution Spinel Oxides, Brian D. Hosterman

UNLV Theses, Dissertations, Professional Papers, and Capstones

Solid solution spinel oxides of composition MgxNi1−xCr2O4, NiFexCr2−xO4, and FexCr3−xO4 were synthesized and characterized using x-ray diffraction and Raman spectroscopy. Frequencies of the Raman-active modes are tracked as the metal cations within the spinel lattice are exchanged. This gives information about the dependence of the lattice vibrations on the tetrahedral and octahedral cations. The highest-frequency Raman-active mode, A1g, is unaffected by substitution of the divalent tetrahedral cation, whereas the lower frequency vibrations are more strongly affected by substitution of the tetrahedral cation. The change in wavenumber of many phonons is nonlinear upon cation exchange. All detected modes of MgxNi1−xCr2O4 and …

Assessing A Combined Theories Approach To Climate Change Communication, Ted Greenhalgh

UNLV Theses, Dissertations, Professional Papers, and Capstones

This research examines the complexities of communicating climate change risk information and the underlying individual attitudes and message content that affect message reception. Using climate change messages incorporating fear appeals and normative information subject's reactions to the messages were evaluated using the Theory of Planned Behavior model. The study found that fear appeals did increase behavioral intention to adopt a lower carbon lifestyle among test group subjects. The Theory of Planned Behavior model showed that attitudes and self-efficacy were significant predictors of the behavioral intent to adopt a lower carbon lifestyle, while community norms were only marginally predictive. However, not …

Structural, Electrical And Thermoelectric Properties Of Chromium Silicate Thin Films, Makram Abd El Qader

UNLV Theses, Dissertations, Professional Papers, and Capstones

Thermoelectric devices can generate electrical power as a result of their ability to produce electrical currents in the presence of thermal gradients. They can also produce refrigerative cooling when electrical power is supplied to them. Among the potential semiconducting silicides, CrSi ₂ is attractive because of its high thermal and chemical stability and its potential for thermoelectric application. CrSi₂ /SiO₂ thin-film structures were prepared using RF sputtering. As deposited and annealed (300°C to 600°C) thin films were characterized for their structural, electrical, and thermoelectric transport properties. As-sputtered CrSi ₂ film is amorphous at room temperature and crystallizes around …

Predicting Intent To Install A Rain Garden To Protect A Local Lake: An Application Of The Theory Of Planned Behavior, Bret R. Shaw, Barry T. Radler, Richard Chenoweth, Paul Heiberger, Paul Dearlove

Journal of Extension

Many lakes are degraded by urban stormwater runoff. One way to reduce these impacts is installing rain gardens that absorb water running off impervious surfaces. The study reported here explored how the Theory of Planned Behavior (TPB) can be used to inform storm water management outreach campaigns. Regression analyses of survey data were used to inform how Extension natural resource educators can more effectively encourage people to install rain gardens. Attitudes toward rain gardens and subjective norms were positively associated with behavioral intent. Perceived behavioral control was not significantly associated with behavioral intent. Implications for Extension educators are discussed.

Mapping The River Kilometers Of Potential Daylighting Projects In Northeast New Jersey, Omoniyi Ayodeji Asaolu

Theses, Dissertations and Culminating Projects

A river offers many benefits to people who live near it, including transportation, a source of food, waste disposal, and water resources for consumption. Because of these advantages many great cities were built around rivers impacting rivers in many ways. While the effects of urban development on water quality have long been studied, this study measures how development has caused streams to disappear from the landscape. It was observed that some streams were buried due to negative impacts of urbanization. Public safety and flood control were some of the reasons these streams were buried, but with the advent of green …

Factors Predicting Exercise Behavior Of Graduate Students, Bibha Gautam

Theses and Dissertations

Graduate school is often experienced as a time of increased demands/expectations resulting in heightened levels of stress due to academic work, family responsibilities, job demands, financial pressure, and other life related issues. Besides stress, graduate school also brings about significant physical inactivity due to the shift of the immediate priority to academic accomplishment. Reports of increasing prevalence of cardiovascular disease (CVD) risk factors among students highlight that this group may have particular risk not well-identified. Yet, relative risk can be reduced by lifestyle modifications, such as eating well, exercising, and stress reduction. The majority of the risk factors, to a …

Managing Stormwater Runoff With Green Infrastructure: Exploring Practical Strategies To Overcome Barriers In Citywide Implementation, Shaojing Tian

Community and Regional Planning Program: Theses

Cities in the United States are facing the challenges of protecting water resources, drinking water and public health with a rapid pace of population growth and urban sprawl. Large quantities of stormwater runoff arising from increased imperviousness on urbanizing watershed will cause municipal sewer system overflow and discharge of untreated runoff into waterways, and as a result, pollute local water bodies and affect the quality of drinking water in the long run. It has been increasingly acknowledged that Green Infrastructure (GI) and Low Impact Development (LID) can be used as an effective tool to capture and retain stormwater on site …
