Energy Reallocation To Breeding Performance Through Improved Nest Building In Laboratory Mice., Brianna N. Gaskill, Kathleen R. Pritchett-Corning, Christopher J. Gordon, Edmond A. Pajor, Jeffrey R. Lucas, Jerry K. Davis, Joseph P. Garner Sep 2013

Energy Reallocation To Breeding Performance Through Improved Nest Building In Laboratory Mice., Brianna N. Gaskill, Kathleen R. Pritchett-Corning, Christopher J. Gordon, Edmond A. Pajor, Jeffrey R. Lucas, Jerry K. Davis, Joseph P. Garner

Department of Comparative Pathobiology Faculty Publications

Mice are housed at temperatures (20-26°C) that increase their basal metabolic rates and impose high energy demands to maintain core temperatures. Therefore, energy must be reallocated from other biological processes to increase heat production to offset heat loss. Supplying laboratory mice with nesting material may provide sufficient insulation to reduce heat loss and improve both feed conversion and breeding performance. Naïve C57BL/6, BALB/c, and CD-1breeding pairs were provided with bedding alone, or bedding supplemented with either 8g of Enviro-Dri, 8g of Nestlets, for 6 months. Mice provided with either nesting material built more dome-like nests than controls. Nesting material improved …

Suspect Subjects: Affects Of Bodily Regulation, Kathryn Henne, Emily I. Troshynski Sep 2013

Suspect Subjects: Affects Of Bodily Regulation, Kathryn Henne, Emily I. Troshynski

Criminal Justice Faculty Research

There is a growing body of academic literature that scrutinises the effects of technologies deployed to surveil the physical bodies of citizens. This paper considers the role of affect; that is, the visceral and emotive forces underpinning conscious forms of knowing that can drive one’s thoughts, feelings and movements. Drawing from research on two distinctly different groups of surveilled subjects – paroled sex offenders and elite athletes – it examines the effects of biosurveillance in their lives and how their reflections reveal unique insight into how subjectivity, citizenship, harm and deviance become constructed in intimate and public ways vis-à-vis technologies …

Four Decades Of Andean Timberline Migration And Implications For Biodiversity Loss With Climate Change, David A. Lutz, Rebecca L. Powell, Miles R. Silman Sep 2013

Four Decades Of Andean Timberline Migration And Implications For Biodiversity Loss With Climate Change, David A. Lutz, Rebecca L. Powell, Miles R. Silman

Dartmouth Scholarship

Rapid 21st-century climate change may lead to large population decreases and extinction in tropical montane cloud forest species in the Andes. While prior research has focused on species migrations per se, ecotones may respond to different environmental factors than species. Even if species can migrate in response to climate change, if ecotones do not they can function as hard barriers to species migrations, making ecotone migrations central to understanding species persistence under scenarios of climate change. We examined a 42-year span of aerial photographs and high resolution satellite imagery to calculate migration rates of timberline–the grassland-forest ecotone–inside and outside of …

Survey Of Nematocerous Flies (Diptera) Of Maupiti, French Polynesia, Limb Hapairai, Dr. C. Riley Nelson Sep 2013

Survey Of Nematocerous Flies (Diptera) Of Maupiti, French Polynesia, Limb Hapairai, Dr. C. Riley Nelson

Journal of Undergraduate Research

Maupiti is a small island located west of Tahiti, French Polynesia. Its isolation from the economic center of Papeete (capital of French Polynesia) has allowed its fauna and flora to stay relatively intact for many years. It’s size and topography also makes this island a good candidate for extensive studies on flies. However little is known about the distribution of species from all 120 islands of French Polynesia since little studies have been done on these islands. Now surveying has become an even more complex problem because endemic and foreign species are given new habitats. For example a monoculture of …

Transgenic Rescue Of Disproportionate Micromelia (Dmm) Mice, Lisa Higgenbotham, Dr. Robert Seegmiller Sep 2013

Transgenic Rescue Of Disproportionate Micromelia (Dmm) Mice, Lisa Higgenbotham, Dr. Robert Seegmiller

Journal of Undergraduate Research

Microinjection is a technique used to introduce DNA into the genome of an animal at the embryo stage. It is an effective way to insert replacement, or rescue, copies of a gene that the embryo may be lacking. In this study, I prepared purified copies of the mouse Col2a1 gene and microinjected them into the pronuclei of single-cell mouse embryos. Col2a1 encodes type II collagen, a major component of cartilage. Mice carrying one or two mutant alleles of Col2a1 are characterized by developmental abnormalities, degenerative joint disease, and even death. This phenotype is observed in Disproportionate micromelia (Dmm) mice, which …

Do Stable Isotope Turnover Rates In Ectotherm Tissues Change With Temperature?, Joseph Franckum, Kent Hatch Sep 2013

Do Stable Isotope Turnover Rates In Ectotherm Tissues Change With Temperature?, Joseph Franckum, Kent Hatch

Journal of Undergraduate Research

Examining the ratios of stable isotopes (non-decaying atoms with extra neutrons) in animal tissues can yield important information about an organism, such as detecting diet change or establishing migratory origin. Information gathered from these studies help develop future practices to care for certain species. A better understanding of an animal’s dietary capabilities will improve animal techniques.

Case Studies Of Tropical Cyclones And Phytoplankton Blooms Over Atlantic And Pacific Regions, Ashley Merritt-Takeuchi, Sen Chiao Sep 2013

Case Studies Of Tropical Cyclones And Phytoplankton Blooms Over Atlantic And Pacific Regions, Ashley Merritt-Takeuchi, Sen Chiao

Faculty Publications, Meteorology and Climate Science

This study investigates phytoplankton blooms following the passage of tropical cyclones in the Atlantic and Pacific Ocean basins. The variables of sea surface temperature (SST), chlorophyll (Chl-a), precipitation, and storm surface winds were monitored for two case studies, Typhoon Xangsane (2006) and Hurricane Earl (2010). Strong near-surface wind from tropical cyclones creates internal friction, which causes deep nutrient enriched waters to displace from the bottom of the ocean floor up toward the surface. In return, the abundance of upwelled nutrients near the surface provides an ideal environment for the growth of biological substances such as chlorophyll and phytoplankton. The inverse …

Factors Explaining Obesity In The Midwest: Evidence From Data, Josh Matti, Hansol Kim Sep 2013

Factors Explaining Obesity In The Midwest: Evidence From Data, Josh Matti, Hansol Kim

Undergraduate Economic Review

This paper attempts to determine the factors explaining obesity in the Midwest by using standard OLS multiple regression analysis and cross-sectional data. We examine independent variables related to built environment and determine effects on obesity. This study finds that some factors influencing calories consumed, such as percent of restaurants that are fast food, are consistent with the prior literature. However, other factors, such as the number of fast food restaurants per 1000 people, yield surprising results. The results of this study suggest that obesity is a multifaceted issue that is not close to being fully explained.

Media Narratives And Possibilities For Teachers’ Embodied Concepts Of Self, Jane S. Townsend, Patrick A. Ryan Sep 2013

Media Narratives And Possibilities For Teachers’ Embodied Concepts Of Self, Jane S. Townsend, Patrick A. Ryan

Journal of Media Literacy Education

Non-print media of radio, television, and film tell narratives about the image and practice of teachers, but how might these media narratives shape conceptions of teachers as well as teachers’ conceptions of themselves? What elements of the media narratives do we incorporate and reject in the narratives that we construct about their professional identities? How do these media and personal narratives interact with larger social narratives, such as the purposes for schools and gender role expectations? We take a historical view of the shaping power of media narratives and the contexts in which they flourished by looking to past depictions …

Design Puzzles As A Learning Platform For Morphology Design Research, Pedro Reissig, Cristhian Castro Arenas Sep 2013

Design Puzzles As A Learning Platform For Morphology Design Research, Pedro Reissig, Cristhian Castro Arenas

Learn X Design Conference Series

Design Puzzles open up a new field of visual and manual learning material for research in design morphology. The way Design Puzzles are instrumental as educational tools involves using them as research systems (frame works) in which spatial / visual problems are posed, requiring formulations of hypothesis as strategies for developing solution paths. The concept can be applied to a wide range of products, (physical and digital), for different ages (K-12 through University) and contexts (open ended play and/or guided classroom situations). Problem identification and approach skills as well as creative thinking strategies are brought into play as spatial / …

Conservation Congress V. U.S. Forest Service, Katelyn J. Hepburn Sep 2013

Conservation Congress V. U.S. Forest Service, Katelyn J. Hepburn

Public Land & Resources Law Review

This case involves challenges to the adequacy of the United States Forest Service’s biological assessment authorizing a timber sale in the Shasta-Trinity National Forest of Northern California. The plaintiff requested an injunction under the Endangered Species Act (“ESA”) alleging that the Forest Service failed to adequately evaluate the effects the timber sale could have on the northern spotted owl’s critical habitat. The Ninth Circuit affirmed the District Court for the Eastern District of California, finding that the Forest Service’s actions did not violate the ESA and that the ESA imposes a lesser requirement than the National Environmental Policy Act (“NEPA”) …

The Terrorism Risk Insurance Act: Time To End The Corporate Welfare, Robert J. Rhee Sep 2013

The Terrorism Risk Insurance Act: Time To End The Corporate Welfare, Robert J. Rhee

Faculty Scholarship

The terrorist attacks of September 11, 2001, inflicted enormous losses on the insurance industry and businesses. In the wake of the disruptions occurring in the insurance market at the time, the government enacted the Terrorism Risk Insurance Act of 2002 to create a “temporary” federal backstop against catastrophic losses. This program subsidized private risk with public funds through a cost-sharing program for which the government does not receive any compensation. The compelling need for the program was unclear even in the smoldering aftermath of 9/11. Yet in response to effective lobbying by the insurance industry and business interests, Congress has …

Ancestry Informative Markers Clarify The Regional Admixture Variation In The Costa Rican Population, Rebeca Campos-Sánchez, Henriette Raventós, Ramiro Barrantes Sep 2013

Ancestry Informative Markers Clarify The Regional Admixture Variation In The Costa Rican Population, Rebeca Campos-Sánchez, Henriette Raventós, Ramiro Barrantes

Human Biology Open Access Pre-Prints

The genetic structure of Costa Rica’s population is complex, both by region and by individual, due to the admixture process that started during the 15th century and historical events thereafter. Previous studies have been done mostly on Amerindian populations and the Central Valley inhabitants using various microsatellites and mtDNA markers. Here, we study for the first time a random sample from all regions of the country with AIMS (Ancestry Informative Markers) to address the individual and regional admixture proportions. A sample of 160 male individuals was screened for 78 AIMs customized in a GoldenGate platform from Illumina. We observed that …

Analysis Of Uniparental Lineages In Two Villages Of Santiago Del Estero, Argentina, Seat Of “Pueblos De Indios” In Colonial Times, Maia Pauro, Angelina García, Rodrigo Nores, Darío A. Demarchi Sep 2013

Analysis Of Uniparental Lineages In Two Villages Of Santiago Del Estero, Argentina, Seat Of “Pueblos De Indios” In Colonial Times, Maia Pauro, Angelina García, Rodrigo Nores, Darío A. Demarchi

Human Biology Open Access Pre-Prints

Based on the analysis of the mitochondrial control region and seven biallelic markers of the Y Chromosome, we investigated the genetic composition of two rural populations of southern Santiago del Estero, Argentina, that were seats in colonial times of “pueblos de indios”, a colonial practice that consisted of concentrating the indigenous populations in organized and accessible settlements, to facilitate Christianizing and policing. We found the Native American Y chromosome haplogroup Q1a3a in only 11% (3/27) of the males. Haplogroup R, common in European populations, is the most frequent haplogroup in Santiago del Estero (55%). In contrast, the persistence of Native …

Biomedical and Pharmaceutical Sciences Faculty Publications

Background/Aims: The small molecule, Tolfenamic acid (TA) has shown anti-cancer activity in pre-clinical models and is currently in Phase I clinical trials at MD Anderson Cancer Center Orlando. Since specificity and toxicity are major concerns for investigational agents, we tested the effect of TA on specific targets, and assessed the cellular and organismal toxicity representing pre-clinical studies in cancer. Methods: Panc1, L3.6pl, and MiaPaCa-2 (pancreatic cancer), hTERT-HPNE(normal), and differentiated/un-differentiated SH-SY5Y (neuroblastoma) cells were treated with increasing concentrations of TA. Cell viability and effect on specific molecular targets, Sp1 and survivin were determined. Athymic nude mice were treated with vehicle or …

How Studies Of Human Sex Ratios At Birth May Lead To The Understanding Of Several Forms Of Pathology, William H. James Sep 2013

How Studies Of Human Sex Ratios At Birth May Lead To The Understanding Of Several Forms Of Pathology, William H. James

Human Biology Open Access Pre-Prints

This paper deals with the problem of the causes of the variation of sex ratio (proportion male) at birth. This problem is common to a number of areas in biology and medicine e.g. obstetrics, neurology/psychiatry, parasitology, virology, oncology and teratology. It is established that there are significantly biased, but unexplained, sex ratios in each of these fields. Yet workers in them (with the possible exception of virology) have regarded the problem as a minor loose end, irrelevant to the field’s major problems. However, as far as I know, no-one has previously noted that unexplained biased sex ratios occur, and thus …

Exploring The Relative Importance Of Spatial And Environmental Variation On The Craniometrics Of The Modern Portuguese, Katherine E. Weisensee Sep 2013

Exploring The Relative Importance Of Spatial And Environmental Variation On The Craniometrics Of The Modern Portuguese, Katherine E. Weisensee

Human Biology Open Access Pre-Prints

Previous research on the causes of craniometric variation within and among human populations has invoked both genetic and environmental explanations. Recent studies of modern populations in the United States and Portugal, among other populations, suggest that changes in environmental conditions have resulted in significant changes in cranial morphology. While similar changes in cranial morphology have been observed in genetically diverse populations, these populations do not appear to be converging on a common form. This study seeks to understand the role that population history and environmental variation play in explaining craniometric variation in the modern Portuguese. Using three-­‐dimensional craniometric data collected …

Feeling The Heat? Substantial Variation In Temperatures Does Not Affect The Proportion Of Males Born In Australia, Barnaby J. Dixson, John Haywood, Philip J. Lester, Diane K. Ormsby Sep 2013

Feeling The Heat? Substantial Variation In Temperatures Does Not Affect The Proportion Of Males Born In Australia, Barnaby J. Dixson, John Haywood, Philip J. Lester, Diane K. Ormsby

Human Biology Open Access Pre-Prints

The global proportion of male births has been shown to vary with climate, with a higher proportion of male births documented in colder climates. Here we examined the hypothesis that ambient temperature predicts fluctuations in the proportion of male births in Australia and within seven Australian states using historical annual data spanning 1910-2009. We predicted that within states with tropical ambient temperatures the proportion of male births would decrease when ambient temperatures are higher. Considering the national composite births for the whole of Australia first, the proportion of males born ranged only from 0.510 to 0.517. We observed no relationship …

Membrane Lipid-Modulated Mechanism Of Action And Non-Cytotoxicity Of Novel Fungicide Aminoglycoside Fg08, Sanjib Shrestha, Michelle Grilley, Marina Y. Fosso, Cheng-Wei Tom Chang, Jon Y. Takemoto Sep 2013

Membrane Lipid-Modulated Mechanism Of Action And Non-Cytotoxicity Of Novel Fungicide Aminoglycoside Fg08, Sanjib Shrestha, Michelle Grilley, Marina Y. Fosso, Cheng-Wei Tom Chang, Jon Y. Takemoto

Chemistry and Biochemistry Faculty Publications

A novel aminoglycoside, FG08, that differs from kanamycin B only by a C8 alkyl chain at the 4″-O position, was previously reported. Unlike kanamycin B, FG08 shows broad-spectrum fungicidal but not anti-bacterial activities. To understand its specificity for fungi, the mechanism of action of FG08 was studied using intact cells of the yeast Saccharomyces cerevisiae and small unilamellar membrane vesicles. With exposure to FG08 (30 µg mL−1), 8-fold more cells were stained with fluorescein isothiocyanate, cells had 4 to 6-fold higher K+ efflux rates, and 18-fold more cells were stained with SYTOX Green in comparison to exposure to kanamycin B …
