Aquatic Invertebrate Monitoring At Agate Fossil Beds National Monument, Lusha Tronstad Jan 2012

Aquatic Invertebrate Monitoring At Agate Fossil Beds National Monument, Lusha Tronstad

United States National Park Service: Publications

Aquatic invertebrates are excellent animals to use for monitoring ecosystem quality; however, how to sample aquatic invertebrates for such monitoring efforts is a central question. All samplers have advantages and disadvantages, and finding the sampler that minimizes bias and fulfills the objectives is crucial. The ecosystem quality of the Niobrara River at Agate Fossil Beds National Monument has been measured for 15 years using aquatic invertebrates colonizing Hester-Dendy samplers. These artificial substrate samplers are useful in rivers that are difficult to sample, but previous studies demonstrated that they bias results toward certain insect orders. Additionally, large debris dams formed upstream …


Thoughts On Quorum Sensing And Fungal Dimorphism, Kenneth W. Nickerson, Audrey L. Atkin, Jessica C. Hargarten, Ruvini U. Pathirana, Sahar Hasim Jan 2012

Thoughts On Quorum Sensing And Fungal Dimorphism, Kenneth W. Nickerson, Audrey L. Atkin, Jessica C. Hargarten, Ruvini U. Pathirana, Sahar Hasim

School of Biological Sciences: Faculty Publications

Farnesol has been best studied for its role in regulating fungal dimorphism. However, farnesol is also a lipid and in this review we analyze data relevant to farnesol’s function and synthesis from the perspective of farnesol and bacterial endotoxins acting as membrane active compounds. This analysis implicates the possible roles of: (1) endotoxins in the regulation of farnesol production by C. albicans; (2) farnesol in the interactions between C. albicans and the host during disseminated infections; and (3) ubiquinones in the mechanisms for unusually high resistance to farnesol by some C. albicans cell types. Finally we discuss the implications …


Illusionary Strength: An Analysis Of Female Empowerment In Science Fiction And Horror Films In Fatal Attraction, Aliens, And The Stepford Wives, Jennifer Lynn Ruben Jan 2012

Illusionary Strength: An Analysis Of Female Empowerment In Science Fiction And Horror Films In Fatal Attraction, Aliens, And The Stepford Wives, Jennifer Lynn Ruben

Master of Humanities Capstone Projects

An expanded notion of empowerment along with three specific theories – Beauvoir’s concept of the Other, Speciesism, Cyborg Feminism – is used to analyze the female protagonists and antagonists in the following 1970’s and 1980’s science fiction and horror films: Fatal Attraction, Aliens, and The Stepford Wives. The female protagonists are allowed more access to power as human beings pitted against nonhuman antagonists, but these characters are ultimately not empowering for women because they reinforce rather than undermine the patriarchal structure. Implications for further research encourage a critique of female empowerment based on both gender and species.


Correlation Of Air Displacement Plethysmography With Alternative Body Fat Measurement Techniques In Men And Women, Brittany L. Reinert, Roberta L. Pohlman, Lynn K. Hartzler Jan 2012

Correlation Of Air Displacement Plethysmography With Alternative Body Fat Measurement Techniques In Men And Women, Brittany L. Reinert, Roberta L. Pohlman, Lynn K. Hartzler

Biological Sciences Faculty Publications

Obesity has reached epidemic proportions with serious health consequences. Techniques used to measure body fat (BF) yield variable BF estimates, and this variability may lead to underestimation or overestimation of BF and subsequent treatment options. The measurements that are most accurate (Dual-Energy X-ray Absorptiometry (DEXA) and Air Displacement Plethysmography (ADP)) are expensive and often unavailable. The purpose of this study is to find the commonly available BF measurement that is the most accurate and practical for individual body types in the general population and compare these measurements to ADP (BOD POD®) as the standard. Field measurements include skinfolds …


Prmt5 And The Role Of Symmetrical Dimethylarginine In Chromatoid Bodies Of Planarian Stem Cells, Labib Rouhana, Ana P. Vieira, Rachel H. Roberts-Galbraith, Phillip A. Newmark Jan 2012

Prmt5 And The Role Of Symmetrical Dimethylarginine In Chromatoid Bodies Of Planarian Stem Cells, Labib Rouhana, Ana P. Vieira, Rachel H. Roberts-Galbraith, Phillip A. Newmark

Biological Sciences Faculty Publications

Planarian flatworms contain a population of adult stem cells (neoblasts) that proliferate and generate cells of all tissues during growth, regeneration and tissue homeostasis. A characteristic feature of neoblasts is the presence of chromatoid bodies, large cytoplasmic ribonucleoprotein (RNP) granules morphologically similar to structures present in the germline of many organisms. This study aims to reveal the function, and identify additional components, of planarian chromatoid bodies. We uncover the presence of symmetrical dimethylarginine (sDMA) on chromatoid body components and identify the ortholog of protein arginine methyltransferase PRMT5 as the enzyme responsible for sDMA modification in these proteins. RNA interference-mediated depletion …

Kno.e.sis Publications

Background

Genome sequencing of many eukaryotic pathogens and the volume of data available on public resources have created a clear requirement for a consistent vocabulary to describe the range of developmental forms of parasites. Consistent labeling of experimental data and external data, in databases and the literature, is essential for integration, cross database comparison, and knowledge discovery. The primary objective of this work was to develop a dynamic and controlled vocabulary that can be used for various parasites. The paper describes the Ontology for Parasite Lifecycle (OPL) and discusses its application in parasite research.

Electrophysiological Abnormalities In Sod1 Transgenic Models In Amyotrophic Lateral Sclerosis: The Commonalities And Differences, Sherif M. Elbasiouny, Katharina Quinlan, Tahra L. Eissa, Charles J. Heckman

Neuroscience, Cell Biology & Physiology Faculty Publications

Since its first description in 1874 by Charcot, the hallmark feature of ALS is the progressive degeneration of upper and lower motoneurons (Charcot, 1874). In the spinal cord, motoneuron degeneration starts long before symptom onset and advances in a size-related fashion, in which large-size alpha-motoneurons degenerate first followed by small-size alpha-motoneurons (Pun et al., 2006; Hegedus et al., 2007; Hegedus et al., 2008). There are conflicting reports regarding the survival of the smallest-sized spinal motoneurons, the gamma-motoneurons (Swash and Fox, 1974; Sobue et al., 1981). Despite its original description, the neuronal degeneration in ALS is not limited to motoneurons. Recent …


Ecogeographic Patterns Of Morphological Variation In Elepaios (Chasiempis Spp.): Bergmann's, Allen's, And Gloger's Rules In A Microcosm, Eric A. Vanderwerf Jan 2012

Ecogeographic Patterns Of Morphological Variation In Elepaios (Chasiempis Spp.): Bergmann's, Allen's, And Gloger's Rules In A Microcosm, Eric A. Vanderwerf

Ornithological Monographs

Animals often exhibit predictable geographic variation in morphology, and such ecogeographic patterns reflect local adaptation to varying environmental conditions. The most common of these patterns are termed Bergmann's, Allen's, and Gloger's rules. I studied morphological variation in the Hawaii Elepaio (Chasiempis sandwichensis) and the Oahu Elepaio (C. ibidis), forest birds endemic to the Hawaiian Islands. I measured body size and plumage color of 223 live elepaios captured at 36 sites on Hawaii and 132 live elepaios captured at 23 sites on Oahu, and I examined 132 museum specimens from an additional 22 locations on Hawaii. I used multiple regressions to …


Morphological Variation Of Rusty Crayfish Orconectes Rusticus (Cambaridae) With Gender And Local Scale Spatial Gradients, Luke Etchison, Stephen J. Jacquemin, Michael Allen, Mark Pyron Jan 2012

Morphological Variation Of Rusty Crayfish Orconectes Rusticus (Cambaridae) With Gender And Local Scale Spatial Gradients, Luke Etchison, Stephen J. Jacquemin, Michael Allen, Mark Pyron

Biological Sciences Faculty Publications

We tested for the influence of gender, stream, and urbanization on morphological variation in rusty crayfish (Orconectes rusticus) in an east-central Indiana, US watershed. We used geometric morphometrics to characterize shape and tested for differences among and within sites. Males had shallower rostrum, increased head width and length, decreased abdomen and cephalothorax width and length, and increased telson length compared to females. Morphology of males did not vary with stream or along an urban gradient. The morphology of females varied with stream and along an urban gradient. Female shapes from small creek sites were stouter and less fusiform …

The Effect Of Dissolved Humic Acids On Aluminosilicate Formation And Associated Carbon Sequestration, Ashaki A. Rouff, Brian L. Phillips, Stacey G. Cochiara, Kathryn L. Nagy

Publications and Research

Allophane and imogolite neogenesis in soils may occur in the presence of organic matter. To understand this process under conditions relevant to soils, the influence of dissolved organic carbon (DOC) as humic acid (HA), on aluminosilicate formation was studied at 25◦C, pH 6, and low-DOC concentrations. For solutions with initial Al/Si ratios of 1–2.1, and 0–6mg/L DOC, precipitates recovered after 20h had Al/Si ratios of 2.2–2.7. The formation of allophane, imogolite-like material, and aluminosilicate gel was confirmed by XRD, FTIR, and NMR. The effect of DOC was to produce a small, but systematic increase in imogolite-like Si in the precipitate, …


The Challenges In The Transition To Adulthood For Foster Care Youth: A Literature Review, Megan Steffe, Carolyn Mcnamara Barry Jan 2012

The Challenges In The Transition To Adulthood For Foster Care Youth: A Literature Review, Megan Steffe, Carolyn Mcnamara Barry

Modern Psychological Studies

The years of emerging adulthood are oftentimes filled with both happiness and anxiety while youth move toward adult roles and responsibilities. According to Courtney and Dworsky (2006), a subset of American emerging adults, those who are transitioning out of foster care face greater vulnerability than do their peers in the general population in a number of issues. As a result, this paper reviewed the literature on the challenges faced by these former foster youth, namely relationships, well-being, substance use, education, employment and finances. Limitations of this extant research are noted along with directions in future research on programs designed to …

On Several Conjectures From Evolution Of Dispersal, Isabel Averill, Yuan Lou, Daniel Munther

Mathematics and Statistics Faculty Publications

We address several conjectures raised in Cantrell et al. [Evolution of dispersal and ideal free distribution, Math. Biosci. Eng. 7 (2010), pp. 17–36 [9 Cantrell, R. S., Cosner, C. and Lou, Y. 2010. Evolution of dispersal and ideal free distribution. Math. Biosci. Eng., 7: 17–36. [CrossRef], [PubMed], [Web of Science ®], [Google Scholar]]] concerning the dynamics of a diffusion–advection–competition model for two competing species. A conditional dispersal strategy, which results in the ideal free distribution of a single population at equilibrium, was found in Cantrell et al. [9 Cantrell, R. S., Cosner, C. and Lou, Y. 2010. Evolution of dispersal …

Interrogating Texts: From Deferent To Efferent And Aesthetic Reading Practices, Cheryl Hogue Smith Jan 2012

Interrogating Texts: From Deferent To Efferent And Aesthetic Reading Practices, Cheryl Hogue Smith

Publications and Research

This article offers a revised version of transactional reading theory to explain how students classified as basic writers tend to employ counterproductive reading and thinking processes that inhibit them from full participation in academic life. Louise Rosenblatt proposes that readers have two main positions or purposes in reading—the efferent stance, where readers focus on the information in a text, and the aesthetic stance, where readers focus on the experience they have with a text. This article describes a third, deferent stance of reading that many basic writers adopt when they defer their interpretations of texts to other readers or defer …

Standardised Classification Of Pre-Release Development In Male-Brooding Pipefish, Seahorses, And Seadragons (Family Syngnathidae), Stefan Sommer, Camilla M. Whittington, Anthony B. Wilson Jan 2012

Standardised Classification Of Pre-Release Development In Male-Brooding Pipefish, Seahorses, And Seadragons (Family Syngnathidae), Stefan Sommer, Camilla M. Whittington, Anthony B. Wilson

Publications and Research

Background: Members of the family Syngnathidae share a unique reproductive mode termed male pregnancy. Males carry eggs in specialised brooding structures for several weeks and release free-swimming offspring. Here we describe a systematic investigation of pre-release development in syngnathid fishes, reviewing available data for 17 species distributed across the family. This work is complemented by in-depth examinations of the straight-nosed pipefish Nerophis ophidion, the black-striped pipefish Syngnathus abaster, and the potbellied seahorse Hippocampus abdominalis.

Results: We propose a standardised classification of early syngnathid development that extends from the activation of the egg to the release of newborn. The classification consists …

One Eternal Round, Hugh W. Nibley, Michael D. Rhodes, Gary P. Gillum Jan 2012

One Eternal Round, Hugh W. Nibley, Michael D. Rhodes, Gary P. Gillum

BYU Studies

Hugh Nibley began serious research on One Eternal Round as early as 1988. When Nibley's long-time colleague Michael D. Rhodes took over the project following Nibley's death in 2005, he was faced with thirty boxes of research notes and drafts, 450 computer files, and as many as twenty versions of one chapter. Fortunately, Michael is familiar with most of Nibley's prodigious output, as well as the subjects listed in the preface, which are a reflection of Nibley's mind and interests and which are all within the scope of One Eternal Round.

Throughout Nibley's long career, his critics have seen him …

Bsa Nanoparticles For Sirna Delivery: Coating Effects On Nanoparticle Properties, Plasma Protein Adsorption, And In Vitro Sirna Delivery, Haran Yogasundaram, Markian Stephan Bahniuk, Harsh-Deep Singh, Hamidreza Montazeri Aliabadi, Hasan Uludag, Larry David Unsworth

Pharmacy Faculty Articles and Research

Developing vehicles for the delivery of therapeutic molecules, like siRNA, is an area of active research. Nanoparticles composed of bovine serum albumin, stabilized via the adsorption of poly-L-lysine (PLL), have been shown to be potentially inert drug-delivery vehicles. With the primary goal of reducing nonspecific protein adsorption, the effect of using comb-type structures of poly(ethylene glycol) (1 kDa, PEG) units conjugated to PLL (4.2 and 24 kDa) on BSA-NP properties, apparent siRNA release rate, cell viability, and cell uptake were evaluated. PEGylated PLL coatings resulted in NPs with ζ-potentials close to neutral. Incubation with platelet-poor plasma showed the composition of …
