Weather And Age Ratios Of Northern Bobwhites In South Texas, Fred S. Guthery, Jeffery J. Lusk, David R. Synatzske, James Gallagher, Stephan J. Demaso

National Quail Symposium Proceedings

Understanding the effects of weather on quail reproduction in semiarid environments requires simultaneous consideration of temperature and precipitation data. Therefore, we used neural modeling to assess the interactive effects of summer (Jun–Aug) temperatures (monthly means of daily maxima) and seasonal precipitation (totals) on age ratios (juvenile/adult) of northern bobwhites (Colinus virginianus) in south Texas based on data collected during 1940–97 (n = 35, 23 years missing). Age ratios increased with June temperature. Ratios were insensitive to mean maximum daily temperature in July up to 36 C, when they began to decline rapidly. Ratios were insensitive to August temperatures. Ratios increased …

Use Of Weather Variables For Predicting Fall Covey Calling Rates Of Northern Bobwhites, Ted P. Seiler, Ronald D. Drobney, Thomas V. Dailey

National Quail Symposium Proceedings

A newly developed technique for estimating fall northern bobwhite (Colinus virginianus) density is currently being employed in parts of the United States. One aspect of this technique involves predicting morning covey calling rates (i.e., the proportion of coveys that call on a given morning). We monitored 60 radiomarked coveys, a total of 229 covey observations, to determine whether or not each covey called. Calling rates were evaluated in relation to date, year, area, temperature, relative humidity, barometric pressure, barometric status, cloud coverage, and wind speed. We used logistic regression to test 9 a priori models as predictive models of bobwhite …

Survival And Habitat Of Pen-Raised Northern Bobwhites At Camp Robinson Wildlife Demonstration Area, Arkansas (Poster Abstract), Matthew D. Lewis, Steven Fowler, Chris Kellner, James C. Bednarz

National Quail Symposium Proceedings

Post-release survival of pen-reared northern bobwhite (Colinus virginianus) is often extremely low. Although predation is usually assumed to cause low survival rates, very little detailed research has been conducted into cause-specific mortality of pen-reared bobwhites in natural settings. Further, little is known about habitat selection by pen-reared bobwhites, and the relationship between habitat and survival. We report results based on 110 radiomarked bobwhites out of 2500 banded and released at Camp Robinson Wildlife Demonstration Area in Arkansas. Birds were released at 125 sites in coveys of 20 birds per site. Release sites were ranked based on habitat quality. In addition, …

Survival And Flight Characteristics Of Captive-Reared And Wild Northern Bobwhites In Texas, Robert M. Perez, Don E. Wilson, Karen D. Gruen

National Quail Symposium Proceedings

Introductions of captive-reared northern bobwhite (Colinus virginianus) to bolster native populations have been largely unsuccessful. We compared the survival and flight characteristics of game-farm (n 46), first-generation (F1) (n = 48), wild translocated (n = 45), and wild native (n = 50) northern bobwhites. In November 1993, all birds were radio-collared, leg banded, sexed, and aged. Birds were then released on a study area in Brooks County, Texas in groups of about 15, 1 bird at a time. Upon release, the direction of departure, speed, and time required to reach cover were recorded. The mean flight speed and distance flown …

Survival And Home Range Estimates Of Pen-Raised Northern Bobwhites In Buffer Strip And Non-Buffer Strip Habitats, Michael J. Oakley, Dixie L. Bounds, Theodore A. Mullet, Karen D. Gruen

National Quail Symposium Proceedings

We investigated the effect of agricultural buffer strips on survival and home range estimates of pen-raised northern bobwhites (Colinus virginianus) at Tudor Farms on the Eastern Shore of Maryland. In September 2000 we released groups of bobwhites into 9 buffer strip (treatment) areas and 9 non-buffer strip (control) areas among 11 agricultural farms. Each group consisted of 4 radiomarked bobwhites and 26 non-radiomarked bobwhites. To maintain contact with the established coveys, additional radiomarked bobwhites (n = 177) were introduced into the coveys as radiomarked birds died. Survival for bobwhites released in buffer strip areas was lower (P < 0.001) than survival in non-buffer strip areas. None of the radiomarked bobwhites released in the buffer strip areas survived past 27 weeks, whereas 11% of radiomarked bobwhites in non-buffer strip areas survived to 27 weeks and 1 bird survived to 41 weeks. Predation was the primary mortality factor (88%), followed by unknown causes (7%), stress (2%), hunting (2%), and road kill (1%). Mean fall and winter home range (95% minimum convex polygon) for 21 bobwhite coveys was 24.2 +- 3.5 ha, ranging from 1.7 to 65.8 ha. Home range areas of bobwhite coveys in buffer strips (n = 12, x¯ +- 15.0 2.7 ha) was significantly smaller (P = 0.002) than non-buffer strip coveys (n = 9, x¯ = 36.4 +- 4.9 ha). We conclude that the smaller home ranges in buffer strip areas seem to indicate better habitat quality; however, high mortality rates of pen-raised bobwhites limited our ability to confirm this.

Bobcat Predation On Quail, Birds, And Mesomammals, Michael E. Tewes, Jennifer M. Mock, John H. Young

National Quail Symposium Proceedings

We reviewed 54 scientific articles about bobcat (Lynx rufus) food habits to determine the occurrence of quail, birds, and mesopredators including red (Vulpes vulpes) and gray fox (Urocyon cinereoargenteus), raccoon (Procyon lotor), skunk (Mephitis spp.), and opossum (Didelphis virginianus). Quail (Colinus virginianus, Cyrtonyx montezumae, Callipepla squamata, C. gambelii, C. californica, Oreortyx pictus) were found in 9 diet studies and constituted 3% of the bobcat diet in only 2 of 54 studies. Birds occurred in 47 studies, but were also a minor dietary component in most studies. Although mesopredators were represented as bobcat prey in 33 of 47 studies, their percent …

Emerging Trends In Midwest Bobwhite Culture, Thomas V. Dailey

National Quail Symposium Proceedings

In the Southeastern United States, Breeding Bird Surveys that bobwhite populations have been declining at 3.8%/year over the last 3 decades. Declines have been attributed the cumulative effects of large-scale deterioration of quail habitat quality associated with advanced succession, intensive monoculture farming, and intensive timber management. Additional factors such as changing role of predation, expansion of red imported fire ants, and metapopulation processes may exacerbate declines. Declining bobwhite hunter participation, changing public values, and realignment of conservation emphases have diminished the emphasis on bobwhite management nationally. However, within the Southeast 3 states, Virginia, Georgia, and North Carolina, have developed targeted …

Arizona Quail: Species In Jeopardy?, Ron Engel-Wilson, William P. Kuvlesky Jr.

National Quail Symposium Proceedings

We begin the 21st century with the Midwestern northern bobwhite (Colinus virginianus) range reduced to a small portion of its historic distribution. This precipitous decline occurred largely during the last quarter of the 20th century, coincident with widespread intensive agricultural land use, unchecked natural plant succession, and frequent severe weather. Various bobwhite enthusiasts of the 1960s–1980s era including Klimstra, Dumke and Stanford had evaluated agricultural land use trends and predicted the near demise of bobwhites that we now lament. Alarmed upland bird hunters have repeatedly spurred policy makers and administrators into action. However, because bobwhites still are only an incidental …

Elucidating Mechanisms Of Protein Aggregation In Alzheimer’S Disease Using Antibody-Based Strategies., Benjamin A. Colvin

Dissertations

Alzheimer’s Disease (AD) is a devastating neurodegenerative disorder. There are two characteristic histopathological hallmarks in the brain: senile plaques and neurofibrillary tangles, composed of insoluble aggregates of the amyloids Amyloid-β (Aβ) and tau protein, respectively. These diagnostic markers, though distinctive, are not apparent effectors of AD pathology. Evidence has mounted suggesting smaller soluble aggregates (oligomers) of Aβ or tau are the true drivers of disease progression. This dissertation presents several amyloid biophysics projects. Aggregate biophysical parameters such as weight, shape, and conformation were measured using a range of methodologies, including Multiangle Light Scattering, Dynamic Light Scattering, UV-Circular Dichroism, UV-Fluorescence, Scanning …

Facial Contrast Is A Cross-Cultural Cue For Perceiving Age, Aurélie Porcheron, Emmanuelle Mauger, Frédérique Soppelsa, Yuli Liu, Liezhong Ge, Olivier Pascalis, Richard Russell, Frédérique Morizot

Psychology Faculty Publications

Age is a fundamental social dimension and a youthful appearance is of importance for many individuals, perhaps because it is a relevant predictor of aspects of health, facial attractiveness and general well-being. We recently showed that facial contrast—the color and luminance difference between facial features and the surrounding skin—is age-related and a cue to age perception of Caucasian women. Specifically, aspects of facial contrast decrease with age in Caucasian women, and Caucasian female faces with higher contrast look younger (Porcheron et al., 2013). Here we investigated faces of other ethnic groups and raters of other cultures to see …

Real-Time Sensing Of Single-Ligand Delivery With Nanoaperture-Integrated Microfluidic Devices, W. Elliott Martin, Ning Ge, Bernadeta R. Srijanto, Emily Furnish, C. Patrick Collier, Christine A. Trinkle, Christopher I. Richards

Chemistry Faculty Publications

The measurement of biological events on the surface of live cells at the single-molecule level is complicated by several factors including high protein densities that are incompatible with single-molecule imaging, cellular autofluorescence, and protein mobility on the cell surface. Here, we fabricated a device composed of an array of nanoscale apertures coupled with a microfluidic delivery system to quantify single-ligand interactions with proteins on the cell surface. We cultured live cells directly on the device and isolated individual epidermal growth factor receptors (EGFRs) in the apertures while delivering fluorescently labeled epidermal growth factor. We observed single ligands binding to EGFRs, …

Let-7 Microrna-Dependent Control Of Leukotriene Signaling Regulates The Transition Of Hematopoietic Niche In Mice, Xuan Jiang, John S. Hawkins, Jerry Lee, Carlos O. Lizama, Nicholas S. Hill, Matthew D. Layne, Akiko Hata, Giorgio Lagna

Biology

Hematopoietic stem and progenitor cells arise from the vascular endothelium of the dorsal aorta and subsequently switch niche to the fetal liver through unknown mechanisms. Here we report that vascular endothelium-specific deletion of mouse Drosha (Drosha cKO), an enzyme essential for microRNA biogenesis, leads to anemia and death. A similar number of hematopoietic stem and progenitor cells emerge from Drosha-deficient and control vascular endothelium, but Drosha cKO-derived hematopoietic stem and progenitor cells accumulate in the dorsal aorta and fail to colonize the fetal liver. Depletion of the let-7 family of microRNAs is a primary cause of this defect, as it …

Parenting Bedtime Behaviors And Sleep Among Toddlers Living With Socioeconomic Adversity, Monica Roosa Ordway, Nancy S. Redeker, Craig Canapari, Sangchoon Jeon, Lois Sadler

International Nursing Research Congress (INRC)

Purpose: Sleep problems are very prevalent during the first year of life with 20-30% of infants reported to have a sleep problem. Families most commonly seek support from pediatric health care clinicians regarding their infant and toddler"s bedtime resistance and frequent and prolonged night wakening. While much has been published describing sleep patterns and sleep interventions to assist parents in helping their children initiate and maintain sleep, the majority of this literature included children living with middle to high incomes. Consistent with other health disparities, sleep disparities occur in children living in socioeconomically disadvantaged homes and emerging literature suggests that …

Disposition represents the sum of one's personal values, commitments, beliefs, and professional ethics. It influences the way a faculty member views teaching and learning, and the quality of responses of involved students. The notion of disposition holds particular significance for advancing the science of nursing education.

Developing And Validating A Problem-Solving Tool For Caregivers To Manage Antineoplastic Treatment For Family Members, Annamaria Bagnasco

International Nursing Research Congress (INRC)

Purpose: To develop and validate an educational tool consisting of a deck of cards for caregivers to educate them to autonomously and safely manage biological antineoplastic oral therapy for their family members at home. This will also increase patients" adherence to treatment.

Methods: We started from the definition of ‘self-management" coined by Corbin & Strauss (1988): ‘Self-management aims at helping patients to maintain a wellness in their foreground perspective" (Lorig & Holman 2003, p. 1). Therefore, self-management is based on the perception patients have about problems linked to their conditions. This led us to choose a method based on the …

Development Of Entrapment Columns For The Study Of Affinity Based Analysis Of Drug–Protein Interactions, Shiden T. Azaria

Department of Chemistry: Dissertations, Theses, and Student Research

High-performance affinity chromatography (HPAC) is a type of liquid chromatography in which solutes are separated based on their binding to a stationary phase that is a biologically-related agent. Because of the strong and selective nature of many biological interactions, this method has already become a powerful technique for the purification and analysis of solutes that are complementary to the immobilized binding agent. Human serum albumin (HSA), the most abundant protein in the blood with concentrations of 35-50 mg/mL in serum, has interactions with many drugs, which can affect the absorption, distribution, metabolism and excretion of such agents.

De Novo Triiodothyronine Formation From Thyrocytes Activated By Thyroid-Stimulating Hormone, Cintia E. Citterio, Balaji Veluswamy, Sarah J. Morgan, Valerie A. Galton, J. Paul Banga, Stephen Atkins, Yoshiaki Morishita, Susanne Neumann, Rauf Latif, Marvin C. Gershengorn, Terry J. Smith, Peter Arvan

Pharmacy Faculty Articles and Research

The thyroid gland secretes primarily tetraiodothyronine (T₄), and some triiodothyronine (T₃). Under normal physiological circumstances, only one-fifth of circulating T₃ is directly released by the thyroid, but in states of hyperactivation of thyroid-stimulating hormone receptors (TSHRs), patients develop a syndrome of relative T₃ toxicosis. Thyroidal T₄ production results from iodination of thyroglobulin (TG) at residues Tyr⁵ and Tyr¹³⁰, whereas thyroidal T₃ production may originate in several different ways. In this study, the data demonstrate that within the carboxyl-terminal portion of mouse TG, T₃ is formed …

Investigating The Role Of Long Distance Dispersal In The Response Of Stream Fishes To Urbanization, Andrea Davis

Master of Science in Integrative Biology Theses

I conducted a 7-month mark-recapture study in two watersheds differing in urban impact in order to assess the role that long distance dispersal plays in the response of tolerant stream fishes to urbanization. Our two stream sites included a heavily impacted urban stream (watershed impervious surface cover ~30%) and a mildly impacted rural stream (watershed impervious surface cover ~6%). Species of interest were marked with 12mm HPT PIT tags and included a specialist, Campostoma oligolepis (n=189 urban site, 200 rural site) and a generalist, Lepomis auritus (n=136 urban site, 182 rural site). Three resampling instances for each site were conducted …

Examining The Relationship Between High School Achievement And The Competing Values Framework, Phillip Wayne Nelson Jr.

Electronic Theses and Dissertations Archive

The purpose of this study was to investigate the relationships between student achievement assessed longitudinally in terms of ACTcomposite scores and state-mandated tests of proficiency and the perceived manner in which high schools resolve the tensions and tradeoffs illuminated by the Competing Values Framework(CVF). To answer the study's five research questions, a secondary analysis that applied hierarchical multiple regression to an existing dataset was undertaken. The dataset in question combined information from the 2013 administration of the Teaching, Empowering, Leading, and Learning (TELL) survey in 287 Tennessee high schools with concurrent school demographic and student achievement data archived on the …

Jellyfish Inspired Soft Robot Prototype Which Uses Circumferential Contraction For Jet Propulsion, G Bridge, M Raach, Mf Stoelen

School of Engineering, Computing and Mathematics

© Springer International Publishing AG 2017. Several robotic jellyfish have been designed over the years, yet none have properly mimicked the very efficient method of propulsion that jellyfish use. Using circumferential contraction, water is pushed out the bottom of the bell creating upwards thrust. Jellyfish use this basic movement along with more complex features to move around the seas. In this paper, we attempt to mimic this circumferential contraction using hydraulically actuated silicone bellows that expand and contract a bell made of flexible silicone skin. 3D printed polylactic acid (PLA) was used to make the structure of the robot, and …
