Implications Of Spatial Autocorrelation And Dispersal For The Modeling Of Species Distributions, Volker Bahn

Biological Sciences Faculty Publications

Modeling the geographical distributions of wildlife species is important for ecology and conservation biology. Spatial autocorrelation in species distributions poses a problem for distribution modeling because it invalidates the assumption of independence among sample locations. I explored the prevalence and causes of spatial autocorrelation in data from the Breeding Bird Survey, covering the conterminous United States, using Regression Trees, Conditional Autoregressive Regressions (CAR), and the partitioning of variance. I also constructed a simulation model to investigate dispersal as a process contributing to spatial autocorrelation, and attempted to verify the connection between dispersal and spatial autocorrelation in species’ distributions in empirical …

Estimation Of Current From Near-Field Measurement, Haixiao Weng, Daryl G. Beetner, Richard E. Dubroff, Jin Shi

Electrical and Computer Engineering Faculty Research & Creative Works

Knowledge of high-frequency currents in the chip and chip-package are necessary for EMI analysis and prediction, though measurement of these currents may be difficult to obtain in many cases. One possibility is to estimate currents from near-field scan data. In this paper, measurements were made of the magnetic field over a simple circuit and a chip package. The current flowing in the circuit and the chip lead frame was estimated from the compensated near-field data and compared with measurements made directly on the pins. Estimation was performed both with and without structural information of the lead frame. The susceptibility of …

Rights Of The Terminally Ill In South Dakota, Cooperative Extension Service

SDSU Extension Extra Archives

The South Dakota Legislature passed a law in 1991 recognizing living will declarations. An individual who is of sound mind and is 18 or more years old may make a declaration (living will) that governs the withholding or withdrawing of life-sustaining treatment when he or she is terminally ill. A federal law, effective December 1, 1991, The Patient Self-Determination Act (PSDA), affects all health care facilities including hospitals, nursing homes, and hospices receiving Medicare or Medicaid. It stipulates that individuals must be given written information at the time of admission about their right under state law to accept or refuse …

Immune-Endocrine Interactions In The Lizard Sceloporus Undulatus Hyacinthinus: Testing An Assumption Of The Immunocompetence Handicap Hypothesis, Mukta Chakraborty

All-Inclusive List of Electronic Theses and Dissertations

The immunocompetence handicap hypothesis (IHH) was proposed by Folstad and Karter ( 1992) to describe the role of the endocrine system in ensuring honesty of sexual signaling. Numerous studies have investigated the assumptions of the IHH, but currently there is mixed evidential support in favor of the IHH. The first chapter of this thesis is a review examinining these studies, their limitations, and proposed alternative models and future directions. The second chapter of this thesis presents a study in which we experimentally assesss the testosterone immunosuppression assumption in adult male Sceloporus undulatus lizards. We manipulated circulating androgen levels (Day 0) …

Mobilization Of The Iron Centre In Isca For The Iron-Sulphur Cluster Assembly In Iscu, Baojin Ding, Edward S. Smith, Huangen Ding

Faculty Publications

The biogenesis of iron-sulphur clusters requires the co-ordinated delivery of both iron and sulphur. It is now clear that sulphur in iron-sulphur clusters is derived from L-cysteine by cysteine desulphurases. However, the iron donor for the iron-sulphur cluster assembly still remains elusive. Our previous studies indicated that Escherichia coli IscA, a member of the iron-sulphur cluster assembly machinery, is an iron-binding protein that can provide iron for the iron-sulphur cluster assembly in a proposed scaffold IscU. To determine how the iron centre in IscA is transferred for the iron-sulphur cluster assembly in IscU, we explore the mobility of the iron …

Hedgehog Regulated Slit Expression Determines Commissure And Glial Cell Position In The Zebrafish Forebrain, Michael J.F. Barresi, Lara D. Hutson, Chi Bin Chien, Rolf O. Karlstrom

Biological Sciences: Faculty Publications

Three major axon pathways cross the midline of the vertebrate forebrain early in embryonic development: the postoptic commissure (POC), the anterior commissure (AC) and the optic nerve. We show that a small population of Gfap+ astroglia spans the midline of the zebrafish forebrain in the position of, and prior to, commissural and retinal axon crossing. These glial 'bridges' form in regions devoid of the guidance molecules slit2 and slit3, although a subset of these glial cells express slit1a. We show that Hh signaling is required for commissure formation, glial bridge formation, and the restricted expression of the guidance molecules slit1a, …

Altering The Tropism Of Lentiviral Vectors Through Pseudotyping, James Cronin, Xian Yang Zhang, Jakob Reiser

Faculty Publications

The host range of retroviral vectors including lentiviral vectors can be expanded or altered by a process known as pseudotyping. Pseudotyped lentiviral vectors consist of vector particles bearing glycoproteins (GPs) derived from other enveloped viruses. Such particles possess the tropism of the virus from which the GP was derived. For example, to exploit the natural neural tropism of rabies virus, vectors designed to target the central nervous system have been pseudotyped using rabies virus-derived GPs. Among the first and still most widely used GPs for pseudotyping lentiviral vectors is the vesicular stomatitis virus GP (VSV-G), due to the very broad …

From The Margins Of The Genome: Mobile Elements Shape Primate Evolution, Dale J. Hedges, Mark A. Batzer

Faculty Publications

As is the case with mammals in general, primate genomes are inundated with repetitive sequence. Although much of this repetitive content consists of "molecular fossils" inherited from early mammalian ancestors, a significant portion of this material comprises active mobile element lineages. Despite indications that these elements played a major role in shaping the architecture of the genome, there remain many unanswered questions surrounding the nature of the host-element relationship. Here we review advances in our understanding of the host-mobile element dynamic and its overall impact on primate evolution. © 2005 Wiley Periodicals, Inc.

Phylogeny And Comparative Biogeography Of Pionopsitta Parrots And Pteroglossus Toucans, Jessica R. Eberhard, Eldredge Bermingham

Faculty Publications

Studies of Neotropical birds, and their distributions and areas of endemism, in particular, have been central in the formulation of hypotheses proposed to explain the high species diversity in the Neotropics. We used mtDNA sequence data (ATPase 6 and 8, COI, and cyt b) to reconstruct the species-level phylogenies for two genera, Pionopsitta (Aves: Psittacidae) and Pteroglossus (Aves: Ramphastidae), compare our results with previous morphology-based phylogenetic analyses, and estimate the absolute timing of lineage and biogeographic divergences. Both the Pionopsitta and Pteroglossus phylogenies support a hypothesis of area relationships in which a divergence of the Serra do Mar (Atlantic Forest, …

The Trials And Tribulations Of Eliciting American Indian Voice, Amber Madoll

Masters Theses

In this thesis I explored the application of oral history in the collection, preservation and interpretation of American Indian cultural history. Through the analysis of written ethnographies, published works, oral histories and case studies, this research addresses some of the major debates hindering oral history's admittance as a viable ethnographic and historical resource. The overall intention of this research was to elicit the major methodological issues anthropologists face when employing oral history techniques in American Indian studies so that solid, comprehensive strategies can be created and implemented to strengthen the acceptance and practice of oral history in modem cultural studies. …

Frequency Of Instrumental Delivery Associated With Epidural Analgesia, Nicole D. Abrahamson

Theses and Dissertations

Presently, approximately two-thirds of all women in the United States receive obstetric analgesia for pain relief during labor. Much research has been done on the effects of epidural analgesia on the mother and infant including prolonged labor, lower rate of spontaneous delivery and increased risk of instrumental delivery. There is agreement in the research that epidural analgesia prolongs stage 2 labor, however, debate continues regarding the association of instrumental delivery and epidural analgesia. There is also lack of substantial research regarding discontinuing epidural analgesia late in labor and whether this affects rate of instrumental delivery.

The purpose of this study …

A Cognitive Intervention To Increase The Salience Of Intrinsic Thoughts Associated With Exercise, Katie S. Moran

Master's Theses

A four-week cognitive intervention was created to increase the salience of intrinsic thoughts associated with exercise in moderately extrinsic exercisers. Participants were assigned to either an intervention or control condition. Those in the intervention condition were asked to respond to questions concerning the pleasure, enjoyment and/or satisfaction experienced during or after their exercise regimen each week. Results showed a marginally significant two-way interaction (p = .059) between the control and intervention condition over time. Those in the intervention condition showed a greater increase in intrinsic motivation than those in the control condition. These results. while only marginally significant, were in …

A General Aspect On Soft-Tissue Sarcoma And C-Kit Expression In Primitive Neuroectodermal Tumor And Ewings Sarcoma. Is There Any Role In Disease Process?, Ismail O. Kara, Gulfiliz Gonlusen, Berksoy Sahin, Melek Ergin, Seyda Erdogan

Saudi Medical Journal

OBJECTIVE: Within soft-tissue sarcoma, primitive neuroectodermal tumors have been shown to cover a wide spectrum of small round cell sarcomas, including Ewing9s sarcomas (ES) and primitive neuroectodermal tumors (PNET). The role of the stem cell factor/kit pathway has been investigated in different human tumors especially in chronic myelocytic leukemia and gastrointestinal stromal tumor and an autocrine loop has been assumed in small cell lung carcinoma, and recently in ES and PNET. Our aim is to investigate the c-kit expression in ES and PNET and also to assessed if c-kit has any role in disease process. METHODS: We thoroughly searched the …

Fluorescent Photoinduced Electron Transfer (Pet) Cation Sensors Derived From Natural Products, Kenny Loo

Theses, Dissertations and Culminating Projects

Two new second generation fluorescent switches that are based on the chromophore-spacer-receptor architecture are reported in this thesis. The fluorescence modulation of these switches is a result of quenching or initiating photoinduced electron transfer (PET) between the chromophore and the receptors due to cation binding. These two molecules utilize an alkaloid, anabasine, as the proton receptor, and function as fluorescent off-on-off switches with decreasing pH. One of these molecules also utilizes a coumarin as the chromophore, making it the first rationally designed fluorescent PET system based on natural products. Further studies of two well-known first generation fluorescent switches to achieve …

Determining The Phylogenetic Relationship Of A Collection Of Hydra Strains And Species Using The Mitochondrial Genes : Lrrna, Trna-Trp And Coii, Jacob Zuckman

Theses, Dissertations and Culminating Projects

The discovery of the mitochondrial DNA (mtDNA) in the early 1960’s ushered in the field of organellar genetics. Evidence from both genetic and physical techniques has demonstrated that mtDNA are generally circular in structure, and that they represent the vestigial structure of the ancestral prokaryotic endosymbiont genome (Nosek et al., 1998). The more than 90 vertebrates and invertebrates sequenced to date have been found to have a remarkably constant gene content. With few exceptions, each contains the genes for 13 energy pathway proteins, the 2 RNA components of mitochondrial ribosomes (23S and 16S rRNA), and 22 transfer RNAs (Pont-Kingdon et …

An Iq Test For Federal Agencies? Judicial Review Of The Information Quality Act Under The Apa, Margaret Pak

Washington Law Review

The Information Quality Act (IQA) directs the Office of Management and Budget (OMB) to issue guidelines to federal agencies for ensuring and maximizing the quality, objectivity, utility, and integrity of information disseminated by the agencies. The IQA directs agencies to develop administrative mechanisms whereby a person affected by agency-disseminated information may request correction of information that the person believes does not comply with the OMB's guidelines. The IQA is silent on whether judicial review is available to challenge an agency's decision to deny a "request for correction" (RFC). Regulated parties, legislators, scholars, and other groups have framed judicial review of …

Time-Series Analysis Of Clusters In City Size Distributions, Ahjond S. Garmestani, Craig R. Allen, K. Michael Bessey

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Complex systems, such as urban systems, emerge unpredictably without the influence of central control as a result of adaptive behavior by their component, interacting agents. This paper analyses city size distributions, by decade, from the south-western region of the United States for the years 1890–1990. It determines if the distributions were clustered and documents changes in the pattern of clusters over time. Clusters were determined utilizing a kernel density estimator and cluster analysis. The data were clustered as determined by both methods. The analyses identified 4–7 clusters of cities in each of the decades analysed. Cities cluster into size classes, …

The Nebraska Game and Parks Commission's strategic plan has stated the following management goal for the Missouri River: Restore, protect, and maintain the diversity of historic Missouri River habitats, resources, and ecosystem functions in order that present and future generations may enjoy consumptive and non-consumptive outdoor recreational opportunities (NGPC 1996). To accomplish this goal the Nebraska Game and Parks Commission identified the following five objectives: • To restore terrestrial and aquatic floodplain habitat types by 2008. This would include old oxbows, chutes, side channels, sand bars, backwaters, wetlands, and other shallow water habitats. To restore ftows that reflect the natural …

Age And Quality Of Ground Water And Sources Of Nitrogen In The Surficial Aquifers In Pumpkin Creek Valley, Western Nebraska, 2000, G. V. Steele, J. C. Cannia, S. S. Sibray, V. L. Mcguire

United States Geological Survey: Publications

Ground water is the source of drinking water for the residents of Pumpkin Creek Valley, western Nebraska. In this largely agricultural area, shallow aquifers potentially are susceptible to nitrate contamination. During the last 10 years, ground-water levels in the North Platte Natural Resources District have declined and contamination has become a major problem for the district. In 2000, the U.S. Geological Survey and the North Platte Natural Resources District began a cooperative study to determine the age and quality of the ground water and the sources of nitrogen in the aquifers in Pumpkin Creek Valley.

Water samples were collected from …
