Vertebrate Body Size Jumps The Wright Way, Peter J. Wagner

School of Biological Sciences: Faculty Publications

Fossil data provide copious evidence that anatomical (morphological) change within individual lineages is not constant: short bursts of great change commonly separate long durations of little change (1, 2). Despite this, most models of morphological change assume that probabilities of morphological character change are the same from one generation to the next: even if rates change over time—such as in “Cambrian explosion” or “early burst” models, where high disparity among anatomies evolves early—then it is still assumed that fast rates of continuous character change gave way to slow rates of continuous change (3). In statistical parlance, early bursts usually are …

Reproductive Success Of Mariana Swiftlets (Aerodramus Bartschi) On The Hawaiian Island Of O’Ahu, Nathan C. Johnson, Susan M. Haig, Stephen M. Mosher, Jeff P. Hollenbeck

U.S. Navy Research

Mariana Swiftlets (Aerodramus bartschi) are federally listed as endangered, with populations currently limited to just three islands in the Mariana Islands plus an introduced population on the Hawaiian island of O’ahu. Before efforts are made to reintroduce Mariana Swiftlets to other islands in the Mariana archipelago, additional information is needed concerning their breeding biology. Therefore, our objective was to examine the reproductive biology of Mariana Swiftlets over five annual cycles on the Hawaiian island of O’ahu. This introduced population used a human-made tunnel for roosting and nesting, and was studied as a surrogate to negate interference with endangered …

Introductory Biology Students’ Use Of Enhanced Answer Keys And Reflection Questions To Engage In Metacognition And Enhance Understanding, Jaime L. Sabel, Joseph T. Dauer, Cory T. Forbes

School of Natural Resources: Faculty Publications

Providing feedback to students as they learn to integrate individual concepts into complex systems is an important way to help them to develop robust understanding, but it is challenging in large, undergraduate classes for instructors to provide feedback that is frequent and directed enough to help individual students. Various scaffolds can be used to help students engage in self-regulated learning and generate internal feedback to improve their learning. This study examined the use of enhanced answer keys with added reflection questions and instruction as scaffolds for engaging undergraduate students in self-regulated learning within an introductory biology course. Study findings show …

Patterns Of Variation In Deciduous Second And Permanent First Molars Among Chimpanzee Taxa, Livia A. Taylor

Anthropology Department: Theses

This project aims to expand our understanding of the utility of molar outline morphology in discriminating between primate taxa as well as to determine whether there is a significant advantage to using deciduous second molars (dm2) over permanent first molars (M1). Recent research in paleontology and paleoanthropology have demonstrated the usefulness of Elliptical Fourier Analysis of molar crown outlines in distinguishing between closely related animal taxa, including hominins, mice, and pigs. I apply this methodology to three Pan taxa: Pan paniscus, Pan troglodytes troglodytes, and Pan troglodytes schweinfurthii to determine how well biological distance information gleaned from molar outline analysis …

Middle Miocene Paleoenvironmental Reconstruction Of The Central Great Plains From Stable Carbon Isotopes In Large Mammals, Willow H. Nguy

Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research

Middle Miocene (18-12 Mya) mammalian faunas of the North American Great Plains contained a much higher diversity of apparent browsers than any modern biome. This has been attributed to greater primary productivity, which may have supported greater browser diversity that commonly corresponds with densely vegetated habitats. However, several lines of proxy evidence suggest that open woodlands or savannas dominated middle Miocene biomes; neither of which support many browsers today. Stable carbon isotopes in mammalian herbivore tooth enamel were used to reconstruct vegetation structure of middle Miocene biomes.

Stable carbon isotopes in C₃ dominated environments reflect vegetation density and herbivores …

From Icon Of Empire To National Emblem: New Evidence For The Fallow Deer Of Barbuda, Sophia Perdikaris, Allison Bain, Sandrine Grouard, Karis Baker, Edith Gonzalez, A. Rus Hoelzel, Holly Miller, Reaksha Persaud, Naomi Sykes

Department of Anthropology: Faculty Publications

Barbuda and Antigua’s national animal is the fallowdeer, Dama dama dama, a species native to the eastern Mediterranean that has been transported around the world by people during the last 8000 years. The timing and circumstances by which fallow deer came to be established on Barbuda are currently uncertain but, by examining documentary, osteological and genetic evidence, this paper will consider the validity of existing theories. It will review the dynamics of human–Dama relationships from the 1500s AD to the present day and consider how the meaning attached to this species has changed through time: from a symbol of colonial …

Chitosan Nanoparticle Modifications For Improved Gene Delivery In An Oral Dna Vaccine Application, Austin Helmink

Honors Theses

Vaccines represent one of the most significant medical innovations of the 20^th century, resulting in the eradication or near eradication of a handful of deadly diseases. However, many infectious diseases remain resistant to effective vaccination, largely due to a lack full immune activation by traditional protein-based vaccines. A promising alternative vaccination strategy is the emerging development of DNA vaccines, which rely upon the delivery of exogenous genetic material to host cells encoding for a viral or bacterial antigen in order to induce a robust immune response by closely mimicking live infection. The delivery of genetic material requires a carrier …

Developing Citizenship Through Honors, Jacob Andrew Hester, Kari Lynn Besing

Journal of the National Collegiate Honors Council Online Archive

For decades, research has shown that higher levels of education correspond to increased interest in politics and civic engagement. Despite the vast amount of scholarly attention, why this link exists is still disputed. One theory about the connection is the civic education hypothesis, which claims that the causal link between education and civic engagement depends not only on the amount of education a person receives but also on the type of curriculum studied. For example, Hillygus argues that “some courses are more likely than others to develop the skills fundamental to political participation” (31). Similarly, Condon argues that the development …

The Host Microbiome Regulates And Maintains Human Health: A Primer And Perspective For Non-Microbiologists, Sunil Thomas, Jacques Izard, Emily Walsh, Kristen Batich, Pakawat Chongsathidkiet, Gerard Clarke, David A. Sela, Alexander J. Muller, James M. Mullin, Korin Albert, John P. Gilligan, Katherine Diguilio, Rima Dilbarova, Walker Alexander, George P. Prendergast

Department of Food Science and Technology: Faculty Publications

Humans consider themselves discrete autonomous organisms, but recent research is rapidly strengthening the appreciation that associated microorganisms make essential contributions to human health and well being. Each person is inhabited and also surrounded by his/her own signature microbial cloud. A low diversity of microorganisms is associated with a plethora of diseases, including allergy, diabetes, obesity, arthritis, inflammatory bowel diseases, and even neuropsychiatric disorders. Thus, an interaction of microorganisms with the host immune system is required for a healthy body. Exposure to microorganisms from the moment we are born and appropriate microbiome assembly during childhood are essential for establishing an active …

Negotiating Refugee Empowerment(S) In Resettlement Organizations, Sarah Steimel

Department of Communication Studies: Faculty Publications

In-depth interviews with both organizational staff and refugee-clients in two American refugee resettlement organizations explore how empowerment is communicated to and understood by refugees being “empowered.” This study found that while organizational staff professed empowerment focused on self-sufficiency as self-determination, in practice their communication to clients defined self-sufficiency a priori in economic terms. Refugee-clients instead constructed empowerment(s) in economic, educational, personal, and family terms. These findings highlight the need for changes in US resettlement policy and for theoretical and practical understandings of refugee empowerment to recognize polysemic and conflicting empowerments in different life arenas and from different positionalities.

Sublethal Effects Of Vatpase-A And Snf7 Dsrnas On Biology Of Southern Corn Rootworm, Diabrotica Undecimpunctata Howardi Barber, Adriano E. Pereira, Ana María Vélez, Lance J. Meinke, Blair D. Siegfried

Department of Entomology: Faculty Publications

RNA interference is a powerful tool against corn rootworm. Adults and neonates of southern corn rootworm, Diabrotica undecimpunctata howardi Barber (Coleoptera: Chrysomelidae), were exposed to the LC₅₀ of vATPase-A and Snf7 double-stranded RNAs (dsRNAs), and the effects on female fecundity, egg viability, male fitness as measured by sperm viability and mating capacity, larval recovery along with dry weight, and instar determination 10 d after exposure to dsRNA, were determined. Significant reductions were observed for a number of parameters in dsRNA-exposed rootworms relative to control treatments. Female fecundity and larval recovery were significantly reduced after exposure to both dsRNAs. In …

Fitness Costs Associated With Cry1f Resistance In The European Corn Borer, J. L. Petzold-Maxwell, Blair D. Siegfried, R. L. Hellmich, C. A. Abel, B. S. Coates, Terrence A. Spencer, R. J. Horikoshi, Aaron J. Gassmann

Department of Entomology: Faculty Publications

Crops producing insecticidal toxins derived from the bacterium Bacillus thuringiensis (Bt) are widely planted to manage insect pests. Bt crops can provide an effective tool for pest management; however, the evolution of Bt resistance can diminish this benefit. The European corn borer, Ostrinia nubilalis H€ubner, is a significant pest of maize and is widely managed with Bt maize in the Midwest of the United States. When Bt crops are grown in conjunction with non-Bt refuges, fitness costs of Bt resistance can delay the evolution of resistance. Importantly, fitness costs often vary with ecological factors, including host-plant genotype and diapause. In …

The Effect Of Feed Form On Diet Digestibility And Cecal Parameters In Rabbits, Isabella Corsato Alvarenga, Charles Gregory Aldrich, Micah Kohles

School of Veterinary and Biomedical Sciences: Faculty Publications

Fifteen New Zealand rabbits were randomly assigned to one of 3 dietary treatment groups of 5 animals each and fed pelleted, extruded, or muesli diets in a completely randomized design experiment. Rabbits were placed in individual cages with ad libitum access to water and food for 45 days acclimation followed by 30 days experimental period. Feed intake of rabbits fed pelleted and extruded diets was greater (p < 0.05) than rabbits fed the muesli diet (125.6 and 130.4 vs. 91.9 g/d), but weight change and feed efficiency were not affected by treatment. Diet digestibility among the treatments was inconsistent when comparing results obtained from total fecal collection and AIA (please define) as an internal marker. Rabbits fed extruded and pelleted diets had lower (p < 0.05) cecal pH (6.42 and 6.38 vs. 7.02, respectively), and higher (p < 0.05) production of SCFA (18.5 and 19.0 vs. 11.7 mM, respectively) than those fed muesli. The fermentation products from rabbits fed pelleted and extruded diets had a greater proportion of butyrate and less propionate than rabbits fed muesli. The results of this study indicate that the basal dietary composition had a greater impact on diet utilization and cecal fermentation than food form.

Growth Mechanisms Of Multiscale, Mound-Like Surface Structures On Titanium By Femtosecond Laser Processing, Edwin Peng, Ryan Bell, Craig A. Zuhlke, Meiyu Wang, Dennis R. Alexander, George Gogos, Jeffrey E. Shield

Department of Mechanical and Materials Engineering: Faculty Publications

Femtosecond laser surface processing (FLSP) can be used to functionalize many surfaces, imparting specialized properties such as increased broadband optical absorption or superhydrophobicity/-hydrophilicity. In this study, the subsurface microstructure of a series of mound-like FLSP structures formed on commercially pure titanium using five combinations of laser fluence and cumulative pulse counts was studied. Using a dual beam Scanning Electron Microscope with a Focused Ion Beam, the subsurface microstructure for each FLSP structure type was revealed by cross-sectioning. The microstructure of the mounds formed using the lowest fluence value consists of the original Ti grains. This is evidence that preferential laser …

USDA Wildlife Services: Staff Publications

Transmission of pathogens among animals is influenced by demographic, social, and environmental factors. Anthropogenic alteration of landscapes can impact patterns of disease dynamics in wildlife populations, increasing the potential for spillover and spread of emerging infectious diseases in wildlife, human, and domestic animal populations. We evaluated the effects of multiple ecological mechanisms on patterns of pathogen exposure in animal populations. Specifically, we evaluated how ecological factors affected the prevalence of Toxoplasma gondii (Toxoplasma), Bartonella spp. (Bartonella), feline immunodeficiency virus (FIV), and feline calicivirus (FCV) in bobcat and puma populations across wildlandurban interface (WUI), low-density exurban development, and wildland habitat …

The nematode Angiostrongylus cantonensis is a zoonotic pathogen and the etiological agent of human angiostrongyliasis or rat lungworm disease. Hawai`i, particularly east Hawai`i Island, is the epicenter for angiostrongyliasis in the USA. Rats (Rattus spp.) are the definitive hosts while gastropods are intermediate hosts. The main objective of this study was to collect adult A. cantonensis from wild rats to isolate protein for the development of a blood-based diagnostic, in the process we evaluated the prevalence of infection in wild rats. A total of 545 wild rats were sampled from multiple sites in the South Hilo District of east …

Ontogenetic And Ecological Variation In Invasion Risk Of Brown Treesnakes (Boiga Irregularis) On Guam, Shane R. Siers, Julie A. Savidge, Robert N. Reed

USDA Wildlife Services: Staff Publications

Size structure within populations of invasive species may have consequences for relative risk at all stages of the invasion process, with implications for management interventions such as interdiction, suppression, and eradication. To assess relative distributions of invasive Brown Treesnakes (Boiga irregularis) among demographic categories of management interest, we undertook the most comprehensive and controlled sampling in > 25 years of research into this ecologically and economically destructive introduced predator. We collected a seasonally-balanced sample of 100 snakes from each of 18 sites, stratified by six habitat types, encompassing the species’ entire extralimital range. Samples indicated significant differences in distributions …

Educational Development As Pink Collar Labor: Implications And Recommendations, Lindsay Bernhagen, Emily Gravett

To Improve the Academy: A Journal of Educational Development

Against a backdrop of other professional arenas, including higher education, this article examines the field of educational development—who we are (mostly women) and what we do (care, service, and emotional labor)—through the lens of gender. While we suggest that educational development may provide a positive counterexample to the male dominance in other higher education professions, we also argue that the common devaluing of women and their labor, well- documented in other arenas, may contribute to educational developers’ "marginal" positions on campuses, our difficulties getting "invited to the table," as well as our challenges in becoming more involved in organizational development …
