A Phylogenomic Study Of The Genus Alphavirus Employing Whole Genome Comparison, Aimée J. Luers, Sandra Adams, John V. Smalley, James Campanella

Department of Biology Faculty Scholarship and Creative Works

The phylogenetics of the genus Alphavirus have historically been characterized using partial gene, single gene or partial proteomic data. We have mined cDNA and amino acid sequences from GenBank for all fully sequenced and some partially sequenced alphaviruses and generated phylogenomic analyses of the genus Alphavirus genus, employing capsid encoding structural regions, non-structural coding regions and complete viral genomes. Our studies support the presence of the previously reported recombination event that produced the Western Equine Encephalitis clade, and confirm many of the patterns of geographic radiation and divergence of the multiple species. Our data suggest that the Salmon Pancreatic Disease …

Environmental, Genetic, And Maternal Effects On Life-History Traits Of The Striped Ground Cricket, Allonemobius Socius, Diana Lea Huestis

Biology Theses - Archive

Organismal fitness is affected by environmental and genetic factors. More importantly, an interaction between an individual's genotype and current environmental conditions influences the success of that individual in its environment. Significant geographic and environmental correlates of allele frequencies at the Idh-1 locus, combined with a significant genotype-by-environment (GxE) interaction between Idh-1 genotype and temperature that affected fitness of Allonemobius socius, support the hypothesis that allele distributions in this species are the result of natural selection on performance of different genotypes at different temperatures. Additionally, I found that an interaction between parental diapause history and egg-incubation temperature affected the proportion of …

Family Structure Effects On Parenting Stress And Practices In The African American Family, Daphne S. Cain, Terri Combs-Orme

The Journal of Sociology & Social Welfare

The predominant approach to African-American parenting research focuses on disadvantages associated with single parenthood to the exclusion of other issues. The current research suggests that this does not represent the diversity in family structure configurations among African-American families, nor does it give voice to the parenting resilience of single mothers. We argue that rather than marital status or family configuration, more attention needs to be given to the inadequacy of resources for this population.

In the current study, we examined the parenting of infants by African- American mothers and found that mothers' marital status and family configuration did not affect …

Patterns Of Cortical Growth As Indicators Of Population Health: An Exploratory Analysis Of Subadult Remains From The Tell Abraq Site, Uae, Jessica L. Rhodes

Masters Theses

The analysis of children in archaeological contexts is a relatively new field of study that emerged largely as a result of feminist and gender studies in the social sciences. Thus, methodologies that are typically employed in bioarchaeological analyses of children have yet to be refined and standardized. The commingling of subadult remains in archaeological contexts further confounds this issue by eliminating the ability of the researcher to establish reasonable age-at-death distributions.

This study seeks to explore the utility of analyzing patterns of cortical growth-for-diaphyseal length in commingled subadult remains. Specifically, commingled subadult remains excavated from the Tell Abraq site (UAE, …

Bone Density Testing As An Early Detection Devise For Anorexia Nervosa And Osteoporosis In Pre-Adolescent And Adolescent Girls, Kelle L. Brooks

Masters Theses

Osteoporosis has become one of the leading health problems for postmenopausal women in the United States, however, it has been shown that preadolescent and adolescent girls with anorexia nervosa are at an unusually high risk for early on-set osteoporosis and bone fractures.

Bone density testing has already proving itself as an accurate form of detection in post-menopausal women and the elderly and is widely used at medical institutions, clinics, and pharmacies throughout the United States as an inexpensive, non-invasive, and accurate technique for detecting low bone mass.

This research aims to examine anorexia nervosa and its long-term effects on the …

Northern Saw-Whet Owls: Rare Or Overlooked? An Example From The Central Platte Valley, Daniel H. Kim

Nebraska Bird Review

Assessing the population status for species requires accurate measures of local or regional numbers. For many species, standardized protocols exist for estimating local numbers through visual counts (e.g., Breeding Bird Survey routes, Christmas Bird Count circles, and point count protocols used by the US Forest Service). For many raptor species, monitoring populations at migratory bottlenecks such as the Goshute Mountains, NV, Hawk Mountain, PA, and Cape May, NJ, provide yearly indices of population health. Unfortunately, most monitoring protocols overlook a suite of small crepuscular or nocturnal species. Project Owlnet (www.projectowlnet.org) is a volunteer-based network of banding stations focusing on Northern …

Influence Of Biocontrol Insects On Canada Thistle: Seed Production, Germinability, And Viability, Gary E. Larson, Tim A. Wittig, Kenneth F. Higgins, Brent Turnipseed, Dawn M. Gardner

The Prairie Naturalist

We conducted surveys of thistle-feeding insects on Canada thistle [Cirsium arvense (L.) Scop.] during the 2000 and 2001 growing seasons at Lacreek National Wildlife Refuge (LNWR), South Dakota, and analyzed their impact on thistle seed production, germination, and viability. Insects included Canada thistle stem weevil [Hadroplontus litura, formerly Ceurtorhynchus lilura, (Coleoptera: Curculionidae)], introduced at LNWR as a biocontrol agent, plus two seed head parasites, the thistle head weevil [Rhinocyllus conicus (Coleoptera: Curculionidae)] and the seed head fly [Terellia ruficauda (Diptera: Tephritidae)]. Infestation by these insects caused no significant reduction in per-head seed yield, with means ranging from 82.5 seeds per …

Christmas Bird Counts For North Dakota 2004, Robert N. Randall

The Prairie Naturalist

Christmas Bird Counts were made in 21 areas in North Dakota again in the year 2004. During the year a new count site was established in Pembina County and registered with the Audubon Society but an actual count was not made in the area this year. The location of the all areas in which counts were actually made is shown in Fig. 1. A relatively mild fall season leading up to the count period left much more open water than normal. Weather conditions during the count period varied widely with some areas reporting temperatures in the 40's and 50's of, …

Biological Notes On Ground-Nesting Digger Wasps From Western Nebraska, Robert W. Matthews, Janice R. Matthews

The Prairie Naturalist

Nine species of sphecid wasps nesting in sparsely vegetated sandy soils near Ogallala, Keith County, Nebraska were studied during June 2003. The first records of the nest and prey of Cerceris clypeata gnarina Banks and Tachysphex williamsi R. Bohart are presented. Two species of weevils, Baris striata Say and B. subsimilis Casey, were prey of C. clypeata gnarina, with 12 to 22 individuals stocked per cell. Because B. subsimilis is a biological control agent for thistle, this finding is a caution to researchers not to ignore the potential impact of predatory wasps on the community. The single nest of T …

Grazing Intensity Effects On Northern Plains Mixed-Grass Prairie, Wendi M. Rogers, Donald R. Kirby, Paul E. Nyren, Bob D. Patton, Edward S. Dekeyser

The Prairie Naturalist

We evaluated the effects of long-term (1988 to 2000) grazing on northern mixed-grass prairie at tI.e Central Grasslands Research Extension Center in south-central North Dakota. We did not detect a difference in herbaceous basal cover between grazing intensities following 12 consecutive years of season-long moderate (50% removal of annual above-ground standing crop) and heavy (80% removal of annual above-ground standing crop) grazing. However, both moderate and heavy grazing intensities reduced above-ground herbaceous standing crop, total root biomass, and soil organic carbon. Moderate grazing intensity maintained a greater amount of deep (10 to 20 cm) and total root biomass relative to …

Electronic Properties Of Silicon Nanowires, Yun Zheng, Christian Rivas, Roger Lake, Khairul Alam, Timothy B. Boykin, Gerhard Klimeck

Other Nanotechnology Publications

The electronic structure and transmission coefficients of Si nanowires are calculated in a 3 5 model. The effect of wire thickness on the bandgap, conduction valley splitting, hole band splitting, effective masses, and transmission is demonstrated. Results from the 3 5 model are compared to those from a single-band effective mass model to assess the validity of the singleband effective mass model in narrow Si nanowires. The one-dimensional Brillouin zone of a Si nanowire is direct gap. The conduction band minimum can split into a quartet of energies although often two of the energies are degenerate. Conduction band valley splitting …

Hydrographic And Biological Changes In The Taiwan Strait During The 1997–1998 El Niño Winter, S. Shang, C. Zhang, H. Hong, Q. Liu, G. T. F. Wong, C. Hu, B. Huang

Marine Science Faculty Publications

During the 1997–1998 El Niño event, the average sea surface temperature (SST) in the Taiwan Strait (TWS) in the winter was ∼1.4°C higher than that of the winter climatological mean. The areal ratio of the warm water (≥2°C above the regional mean) to the cold water (≥2°C below the regional mean) in the TWS increased by 25% while the area of the eutrophic water (chlorophyll a >1 mg m⁻³) was halved. Field observations also indicate that the mixed layer in the TWS became more nutrient-poor during this winter. These observations are consistent with a diminished advection of the …

Competitive Implications Of Perch Site Use By Three Sympatric Kingfishers In South Texas, Michael F. Passmore, Bruce C. Thompson

Bulletin of the Texas Ornithological Society

Green (Chloroceryle americana), Ringed (Ceryle torquata) and Belted Kingfishers (Ceryle alcyon) were studied in the Rio Grande Valley, TX to determine interspecific features of perch sites. Microhabitat characteristics of perch sites appeared similar among the three species, but multivariate analysis indicated little overlap of physical characteristics for Green and Ringed Kingfisher perches. There was extensive overlap of Belted Kingfisher perch site features with those of the other two species during seasonal coexistence. Interspecific encounters between Belted and Ringed Kingfishers are described. Conditions facilitating competitive use of perch sites by kingfishers were associated with a water development project.

Native Texas Avifauna Altered By Suburban Entrapment And Method For Easily Assessing Natural Avifaunal Value, Frederick R. Gehlbach

Bulletin of the Texas Ornithological Society

Suburban sprawl in a central-Texas city gradually entrapped native nesting birds in a heavily wooded ravine. The birds were spot-mapped in 6-ha plots for 39 years, and the kinds and causes of avifaunal change were measured. Habitat area was reduced overall but not in study plots, which were partly modified by sewer-line construction, and temperatures became warmer. Permanent-resident populations were stable or grew with invasions by four species, while three species were lost. Summer-resident populations declined, and nine species were lost. At the end of study, survivors were largely permanent residents and arboreal and cavity nesters by contrast to lost …

A Protocol For The Staining Of Cement Lines In Adult Human Bone Using Toluidine Blue, Daniel L. Osborne, Janene Curtis

Department of Anthropology: Faculty Publications

Increased definition of cement lines aids in the identification of secondary osteons in bone. A staining protocol taken from Burr (Anat Rec 232:180-189, 1991) and modified by Havill using toluidine blue on plastic-embedded bone specimens was applied to cranial core and femoral shaft sections but proved to be too time-consuming and inconsistent. Experimentation resulted in a different protocol for each bone type, perhaps as the result of differences in section thickness and cortical area. Staining of femoral sections proved particularly difficult, with increased etching duration and agitation proving most influential in intensity and uniformity of stain.

Chromatographic Purification Of Mabs With Non-Affinity Supports, Anuradha Subramanian

Papers in Biotechnology

The introduction of new protein-based therapeutics such as monoclonal antibodies (MAbs), MAb-based vaccines, growth factors and plasma proteins implies the need to study, characterize, and purify. The separation step is likely to be a bottleneck and cost-effective technology will be needed to rectify it. The currently prevalent matrices for chromatographic separation of immunoglobulins (Igs) are based on Protein A or its recombinant versions (Protein G). They display excellent selectivity and specificity, but are expensive. A Protein A matrix costs $8,000 to 12,000 per L-resin. The typical production column volume is 100 L. The million-dollar matrix is far more expensive than …

The Legal Function Of Ritual, Geoffrey P. Miller

Chicago-Kent Law Review

This Article offers a theory of ritual as social control. It argues that an important function of rituals is to align personal identities with social roles. The celebratory aspect of rituals reflects the sense of felicity that accompanies the successful alignment of identity and role. Violence in ritual reflects the fact that the alignment of identity and role is compulsory and often imposes significant costs on personal autonomy. Within the framework of this theory, rituals can be classed into three general types: rituals of reformation (e.g., marriage, initiation, and installation) help align identity and role; rituals of renewal (e.g., religious …

A Nontechnical Introduction To "Biocontrol As Usual": Review Of Ann Hajek, Natural Enemies, Svata M. Louda

School of Biological Sciences: Faculty Publications

Increasing recognition of the problems posed by invasive, exotic species has led to a recent upsurge of interest in the potential of biological control as a sustainable management strategy. The idea that ‘‘natural control’’ could be re-established on a species in its new environment is a seductive one, nurtured by a small set of impressive success stories and the belief in a simple solution (‘‘silver bullet’’). Yet, recent serendipitous discoveries also make it clear that attempts to engineer the outcome of species interactions in new systems can lead to undesired direct and indirect effects of unanticipated magnitude on non-targeted native …

The Persistence Of Adult Undergraduates On A Traditionally Oriented University Campus, Wendy Samuels

Dissertations

This phenomenological study describes the social and academic experiences of successful non-traditional students on the main campus of a traditionally oriented residential university and how these experiences promote or impede their persistence to graduation. The study determined what role family support, faculty support, institutional policy and services, and the classroom environment have in persistence of adult undergraduates. The methodology employed open ended individual interviews based on an interview outline. Participants in the study were all students within two traditional semesters of graduation, andthe sampling procedures were purposeful, yielding a fairly diverse pool of 15 participants. Trustworthiness of the data was …
