Evidence Of Hantavirus Exposure In Rodents From North Texas, Richard M. Pitts, Matthew R. Mauldin, Cody W. Thompson, Jerry R. Choate Oct 2013

Evidence Of Hantavirus Exposure In Rodents From North Texas, Richard M. Pitts, Matthew R. Mauldin, Cody W. Thompson, Jerry R. Choate

Western North American Naturalist

Between 27 June 1997 and 16 May 1999, 423 rodents were collected from North Texas (Collin, Denton, and Grayson counties) by using Sherman live-traps (trapping success rate ~22%). Of the 423 rodents collected, 328 were tested for evidence of IgG antibodies to New World hantaviruses. Hantavirus antibodies were detected in 34 individuals (~10%). This is the first record of hantavirus antibody–positive rodents from the highly urbanized area of North Texas.

Ringtail (Bassariscus Astutus) Noninvasive Survey Methods, Density, And Occupancy In Central New Mexico, Usa, Robert L. Harrison Oct 2013

Ringtail (Bassariscus Astutus) Noninvasive Survey Methods, Density, And Occupancy In Central New Mexico, Usa, Robert L. Harrison

Western North American Naturalist

I tested 3 hair-collection devices used for population surveys of ringtails (Bassariscus astutus): PVC pipes, modified cage traps, and triangular Coroplast® tunnels. Coroplast tunnels were the most efficient, with hair obtained by 92% of tunnels tested on radio-collared ringtails. I used the tunnels to survey ringtails on the Sevilleta National Wildlife Refuge in central New Mexico. Probability of detection in areas where ringtails were present was 74% (95% CI 0.56–0.86). Population density was estimated to be 0.17–0.33 ringtails · km–2 and occupancy (Ψ) by ringtails was 0.56 (95% CI 0.35–0.75).

Milnesium Lagniappe, A New Species Of Water Bear (Tardigrada, Eutardigrada, Apochela, Milnesiidae) From The Southern United States, Harry A. Meyer, Juliana G. Hinton, Maria C. Dupré

Western North American Naturalist

Over 200 species of freshwater and terrestrial water bears (phylum Tardigrada) are known to occur in North America. Of these, 20 species have been recorded in Louisiana. Foliose and fruticose lichen and moss samples collected in 2011 in the city of Lake Charles and in Sam Houston Jones State Park, Calcasieu Parish, Louisiana, USA, were stored in paper envelopes and later soaked in tap water overnight. Tardigrade specimens and eggs were extracted and mounted in polyvinyl lactophenol. The samples contained a new species of tardigrade. Milnesium lagniappe sp. n. has claw formula [2-3]-[3-2] and 9 sculptured bands in the dorsal …

Factors Influencing Mortality Associated With The Translocation Of Northern River Otters (Lontra Canadensis) In Utah, Casey C. Day, Matthew D. Westover, Brock R. Mcmillan Oct 2013

Factors Influencing Mortality Associated With The Translocation Of Northern River Otters (Lontra Canadensis) In Utah, Casey C. Day, Matthew D. Westover, Brock R. Mcmillan

Western North American Naturalist

Reintroductions and translocations of northern river otters have been a common management practice throughout the United States from the 1970s to the 2000s. Though many reintroductions have been successful, populations are not always monitored or evaluated post-release. From 2009 through 2012, we translocated 27 radio-marked otters into the Provo River watershed in northern Utah. Our objective was to determine what factors influenced the translocation-related mortality of otters. We developed a series of a priori models and used logistic regression to determine the most influential factors. We used Akaike’s information criterion to evaluate relative model support. We found that the univariate …

Spatial Ecology Of Female Mule Deer In An Area Proposed For Wind Energy Development, Stephen L. Webb, Matthew R. Dzialak, Dean Houchen, Karl L. Kosciuch, Jeffrey B. Winstead Oct 2013

Spatial Ecology Of Female Mule Deer In An Area Proposed For Wind Energy Development, Stephen L. Webb, Matthew R. Dzialak, Dean Houchen, Karl L. Kosciuch, Jeffrey B. Winstead

Western North American Naturalist

Development for wind energy is increasing rapidly across the United States, particularly in Wyoming, despite a general lack of information on the potential interaction development could have on wildlife species. Therefore, knowledge of the space use and movement patterns of individuals can help define spatial distributions and management unit boundaries for populations prior to development. Such knowledge can also be used as baseline data from which to assess any future impacts on animal populations. We investigated the spatial ecology of female mule deer (Odocoileus hemionus; n = 18) equipped with global positioning system collars from 23 February 2011 to …

Rediscovery Of The Snake Chersodromus Rubriventris (Squamata: Colubridae) In Cloud Forest Of The Sierra Madre Oriental, México, Aurelio Ramírez-Bautista, Christian Berriozabal-Islas, Raciel Cruz-Elizalde, Uriel Hernández-Salinas, Luis Badillo-Saldaña

Western North American Naturalist

As presently recognized, the snake genus Chersodromus (Colubridae) is composed of 2 species, C. liebmanni and C. rubriventris, both of which are endemic to eastern Mexico. Distribution of the genus is largely restricted to the states of Veracruz and Oaxaca and broadly corresponds to the south of the Sierra Madre Oriental and the eastern portion of the Transvolcanic Belt. Chersodromus liebmanni is the more common species of the genus and is distributed in the foothills of several localities in central Veracruz and northern Oaxaca. However, C. rubriventris is restricted to only a few small localities in San Luis Potosi …

Microbes: An Educational Picture Book, Heather Stratton, Richard Hull, William Mccleary

Journal of Undergraduate Research

With all the hype and paranoia in our media today about disease causing microbes, the need arises for a more complete picture of these tiny organisms and some of their other roles in our lives to be presented. I have written a children’s story in an attempt to do just this. The book is titled Microbes. It is an acknowledgement of the dangers of microorganisms, but also an explanation of their necessary influence.

Soldaten: The Story Of Slovene Conscripts In Hitler’S Army, Stacey Snider, Thomas Russell Oct 2013

Soldaten: The Story Of Slovene Conscripts In Hitler’S Army, Stacey Snider, Thomas Russell

Journal of Undergraduate Research

In May of 2002 I sat in the riverside backyard of Igor Slavec on a picnic bench with my camera poised. As the Alpine river Sava moved slowly behind him, Igor told me about his family’s history in their village, Struževo, about his father’s experience in WWI, and finally about the predicament in which he found himself in 1943, as an unwilling conscript in the foreign army occupying his homeland. Igor is one of a unique group of WWII participants, confused and exploited, whose story I want to share in the form of a documentary film.

The Marvelous American Reality: Making A Case For Carpentier’S Magical Realism In Latin American Music, Erika Edwards, Dr. Arden Hopkin, Dr. George Handley Oct 2013

The Marvelous American Reality: Making A Case For Carpentier’S Magical Realism In Latin American Music, Erika Edwards, Dr. Arden Hopkin, Dr. George Handley

Journal of Undergraduate Research

In 1949 the Nobel Prize-winning Cuban novelist and musicologist, Alejo Carpentier, published his essay on lo real maravilloso Americano, an aggressively American discussion of the theory now known as magical realism. Carpentier refers to the German art critic Franz Roh (who initially coined the term in reference to post-expressionist painting in 1925), but diverges and defends magical realism as a uniquely Latin American phenomenon. While the world has latched onto Magical Realism as a critical literary theory, it is undeniably the Latin American authors and artists who have embraced, embodied and defined the practice of it. Carpentier asserts that the …

Illustrations For Aesop’S Fables: The Creation Of A Series With A Preliminary Historical And Aesthetic Analysis, Alisa L. Gordon, Robert Barrett, Richard Hull Oct 2013

Illustrations For Aesop’S Fables: The Creation Of A Series With A Preliminary Historical And Aesthetic Analysis, Alisa L. Gordon, Robert Barrett, Richard Hull

Journal of Undergraduate Research

Aesop’s fables are some of the most well known stories, as well as some of the most widely illustrated. They are typically very short, have only a few characters, and have a simple plot. Consequently, the stories provide excellent subject matters for pieces in my illustration portfolio. I can communicate a story in one image, be imaginative, and still expect the story to be recognizable. Art directors will immediately be able to assess my visual story-telling abilities as well as my creativity through my interpretation of some of these well known stories. My objective is to create a series of …

Techniques Of Ceramic Artists In Senegal, West Africa, Amy Beth Harrison, Von Allen Oct 2013

Techniques Of Ceramic Artists In Senegal, West Africa, Amy Beth Harrison, Von Allen

Journal of Undergraduate Research

Information is essential for ceramic artists to increase technical knowledge and as a source of inspiration. With the chance of visiting Senegal, West Africa on a study abroad, I wanted to take advantage of my time there to research the techniques of ceramic artists. My goal was to find out how ceramic artists were working and present this information to students at BYU. I also wanted to acknowledge the contributions of undocumented artists.

The Gothic Revival, David Amott, Dr. Cynthia Finlayson Oct 2013

The Gothic Revival, David Amott, Dr. Cynthia Finlayson

Journal of Undergraduate Research

The Gothic Revival was an important architectural movement of the nineteenth century. It was a result of the nineteenth century Romantic fascination with the Middle Ages. People looked to that era for inspiration in all arts, including architecture. The United States had no authentic Gothic background, so the architect Richard Upjohn became a key player in the Gothic Revival movement there. He transplanted the style of architecture from his native England to the young nation. Among his many commissions were the Trinity Church and the Church of the Holy Communion, both located in New York City.

The Promethean, A Modern Retelling Of The Greek Myth Prometheus, Was Completed In March Of 2003., J. Chad Erekson, Kelly Loosli

Journal of Undergraduate Research

At this point in time, most BYU animation projects have avoided lip sync. The Industrial Design Department produced a computer animated film called Rupert which had some crude imprecise mouth movements to suggest lip sync, but for the most part every traditionally animated project has tried to do complete pantomime, or use narration. With the undertaking of Lion & the Mouse, accurate lip sync was to be attempted, but as production progressed, students still only tackled the non-speaking scenes in their animations. Thus was my motivation for this project. If the lip sync in Lion & the Mouse was to …

Can A Flea See? An Investigation Of Flea Opsin (Flopsin), Sean David Taylor, Dr. Michael F. Whiting Oct 2013

Can A Flea See? An Investigation Of Flea Opsin (Flopsin), Sean David Taylor, Dr. Michael F. Whiting

Journal of Undergraduate Research

Visual pigments are responsible for conferring visual perceptual abilities to animals. Various pigments are tuned to absorb light of different wavelengths and to provide contrast and movement perception. All pigments consist of an opsin protein and a chromophore molecule, usually a carotene derivative. Interactions between the chromophore and amino acid residues of opsin fine-tune visual pigments for the absorption of different wavelengths. Opsin variants can tune visual pigments to absorb wavelengths in the ultraviolet, blue, green, and red regions of the spectrum (Briscoe and Chittka 2001).

Testing Cognition In Amazona Spp, Heidi Francis, Dr. Steven L. Peck Oct 2013

Testing Cognition In Amazona Spp, Heidi Francis, Dr. Steven L. Peck

Journal of Undergraduate Research

Animal intelligence has been studied for years, yet very few people are aware that parrots are ranked near the top with regards to cognition. For almost 20 years Dr. Irene Pepperberg has been teaching African Grey parrots to communicate using language, these birds then use English words to verbally answer questions testing their intelligence level. (Pepperberg, 1995) The teaching method used to do this is called the Model/Rival technique. For my research I chose to test whether this same technique could be used to teach a different species of parrot. Because of their speaking ability and large brain sizes comparable …

Analysis Of Hnf1-Beta As A Possible Regulatory Protein For The Transcription Of The Col11a2 Collagen Gene, Nicholas M. Orme, Dr. Laura C. Bridgewater Oct 2013

Analysis Of Hnf1-Beta As A Possible Regulatory Protein For The Transcription Of The Col11a2 Collagen Gene, Nicholas M. Orme, Dr. Laura C. Bridgewater

Journal of Undergraduate Research

Cartilage is a highly specialized form of connective tissue that functions as a template for most skeletal structures and aids in supporting the tension and pressure common to most animal joint function. Abnormal cartilage formation often results from defective collagen DNA and can lead to several skeletal diseases including dwarfism, cleft palate and osteoarthritis. The purpose of this research was to investigate the regulatory role of HNF proteins in the transcription of the Col11a2 gene which codes for a collagen protein found in cartilage.

Investigation Into The Mechanisms Associated With Angiogenesis And Metastasis, Rachelle R. Olsen, Dr. Kim L. O'Neill Oct 2013

Investigation Into The Mechanisms Associated With Angiogenesis And Metastasis, Rachelle R. Olsen, Dr. Kim L. O'Neill

Journal of Undergraduate Research

Angiogenesis, the development and differentiation of new blood vessels from pre-existing vasculature, is tightly controlled during physiological processes including wound healing, growth, and development. Angiogenesis is also associated with several human malignancies including arthritis, psoriasis, and cancer. Angiogenesis, which provides a source of nutrients and a waste outlet for biological products, is absolutely required for a tumor to grow larger than a few millimeters in size. Blood vessels formed by angiogenesis are young and immature and can facilitate metastasis, the spread and subsequent growth of primary tumor cells to distal body sites.

Anterior-Posterior Limb Position Is Dependent On The Relative Timing Of Key Embryonic Events, Tyler Prestwich, Dr. Michael Stark Oct 2013

Anterior-Posterior Limb Position Is Dependent On The Relative Timing Of Key Embryonic Events, Tyler Prestwich, Dr. Michael Stark

Journal of Undergraduate Research

To better understand embryonic events leading to the determination of limb position along the anterior-posterior (A-P) axis, we compared pre-limb bud stage developmental morphology of three vertebrate organisms: chicken, goose and swan. These organisms were selected because of the differences each exhibit with regard to the A-P location of the forelimbs, or more specifically, the number of cervical vertebrae. By observing disparities between the embryonic morphologies of the different species, we were able to identify specific morphological distinctions that correlate with A-P patterning. Based on the data obtained, we hypothesize a mechanism whereby a delay in embryonic “differentiation” in relationship …

A Col2a1 Mutation Leads To Increased Degradation Of Type Ii Collagen In Articular Cartilage: A Murine Model For Osteoarthritis, Peter Crane, Dr. Robert Seegmiller Oct 2013

A Col2a1 Mutation Leads To Increased Degradation Of Type Ii Collagen In Articular Cartilage: A Murine Model For Osteoarthritis, Peter Crane, Dr. Robert Seegmiller

Journal of Undergraduate Research

Normal articular cartilage is characterized by a resilient collagen and proteoglycan matrix interdispersed with chondrocytes. Collagen type II is the most abundant collagen found in the matrix and is responsible for providing tensile strength to the tissue. The highly conserved Col2a1 gene is responsible for coding all type II collagen á-helix chains.1 The process of enzymatic MMP cleavage is a natural part of collagen recycling, but has been observed to be upregulated in articular cartilage of osteoarthritis (OA) patients. It is hypothesized that further denaturation (unwinding) of enzymatically cleaved collagen takes place following enzymatic cleavage by MMP. Because increased degraded …

Soil Resources Of The Ancient Maya In The Petexbatún Region Of Guatemala, Delineated By Soil Properties And Stable Isotopes, David R. Wright, Dr. Richard E. Terry Oct 2013

Soil Resources Of The Ancient Maya In The Petexbatún Region Of Guatemala, Delineated By Soil Properties And Stable Isotopes, David R. Wright, Dr. Richard E. Terry

Journal of Undergraduate Research

The Maya culture of Mesoamerica has always been shrouded in mystery, much of which surrounds its tremendous rise and (yet) unexplained fall. The Maya managed to sustain enormous populations in an environmentally fragile setting. Like all cultures throughout history, the Maya culture prospered from the soils beneath it. Despite extensive excavation and investigation of Maya sites, relatively little is understood of the agricultural methods that led to such successful subsistence. Understanding is deficient because cultivated areas tend to leave few visible remains besides an occasional terrace or canal, and also because traditionally most investigative efforts have focused on elite structures …

Integrating Technology In Guatemalan Schools, Richard Culatta, Dr. Charles Graham

Journal of Undergraduate Research

With an increase in donations and grants available for technology integration, even schools in remote areas of the world have greater access to technology than ever before. However, as the experience in integrating technology in the United States has shown, the availability of technology doesn’t always equate to it’s effective pedagogical application. Nevertheless, there has been little research concerning the successful process of integrating technology into education in areas of the world that have not had significant previous contact with technology. The purpose of this study is to identify problems and perceptions of teachers in developing countries as they begin …

The Use Of Stable Isotopes To Determine The Physiology And Ecology Of Reptiles, Jessica Makin, Kent Hatch Oct 2013

The Use Of Stable Isotopes To Determine The Physiology And Ecology Of Reptiles, Jessica Makin, Kent Hatch

Journal of Undergraduate Research

Stable isotope research is becoming more widely used in physiological ecology. Atoms of the same atomic number but different atomic weights are called isotopes. Nitrogen (N) has two isotopes, 14N and 15N, with the latter being the heavier isotope. The assumption is that 14N is excreted at a higher rate than 15N. It is also thought that this should cause an increase in 15N of the protein tissues and preferential excretion of 14N of an animal when the animal is in the process of breaking down proteins.

A Real-Time 3d Engine For Students, Joshua Gustafson, Dr. Robert P. Burton Oct 2013

A Real-Time 3d Engine For Students, Joshua Gustafson, Dr. Robert P. Burton

Journal of Undergraduate Research

A real-time 3D engine is a software system which allows a computer to generate and display three-dimensional graphics at interactive speeds. Faster, more capable, and less expensive video hardware has encouraged improvement in real-time engines and a diversification of their applications. They have been used traditionally in applications such as games and simulators, but increasingly are appearing in other applications such as home modeling, ticket purchasing, and other uses. Real-time 3D engines are therefore an area of understandable interest and considerable value to students of Computer Science.

Are Guatemalan K’Ekchi Mormons Really Protestants? A Comparative Look At K’Ekchi Stories, Robert E. M. Spencer, Dr. John Hawkins

Journal of Undergraduate Research

With blackness surrounding us both, Oscar stumbled over the words. Here I was living in the highlands of northern Guatemala, in a dirt floor shack, sitting on my wooden board bed, listening to the struggles of a Mayan man trying to read by candlelight. He was the product of’ Mayan tradition, Catholicism, Protestantism, and Mormonism. With such a mixture I wondered what I would discover, what were the stories that shaped his and his family’s lives? Were they traditional stories? biblical? from a new source? or did his semi-literacy create a barrier to his learning of any stories?

“The Role Of Gaba Electrical Networks In Brain Stimulation Reward”, Seth Gunderson, Dr. Scott Steffensen

Journal of Undergraduate Research

The basis for my project is predicated on the rewarding properties of alcohol and other substances of abuse. We set out to further our understanding the neural system that is involved in intracranial self stimulation (ICSS) and how this system is mediated by γ-aminobutyric acid (GABA) neurons. Studies involving intravenous self administration (SA) of opiates and psychostimulants have identified specific neural substrates that mediate the reinforcing actions of these drugs and they constitute part of the same central nervous reward system that has evolved for mediating natural motivated behaviors, the mesocorticolimbic dopamine (DA) system.1,2
