Development Of Anchor Loci To Map A Bt Resistance Factor In The Domesticated Silkworm, Bombyx Mori, Marc Chatenay-Lapointe May 2006

Development Of Anchor Loci To Map A Bt Resistance Factor In The Domesticated Silkworm, Bombyx Mori, Marc Chatenay-Lapointe

Senior Honors Projects

The BT toxin is an insecticide produced by the bacterium Bacillus thuringiensis, and millions of acres of genetically modified crops expressing this agent have been planted. However, with such widespread use, there is a great potential for pests resistant to this toxin to develop. An understanding of how BT resistance operates and is inherited is central to ensuring continued use of the transgenic crops. Bombyx mori, the domesticated silkworm, is the model organism for the Lepidoptera, an order of insects containing many important agricultural pests. Screening shows that BT resistance is present in some silkworm strains, and linkage group 15 ...


A Comparison Of The Imapct Of Environmental Stressors On Blood Parameters Of Captive Harbor Seals (Phoca Vitulina), Maura Allard May 2006

A Comparison Of The Imapct Of Environmental Stressors On Blood Parameters Of Captive Harbor Seals (Phoca Vitulina), Maura Allard

Senior Honors Projects

Little research has been established in determining blood chemistry values for harbor seals in Alaska. It has been suggested that various environmental factors can influence the blood chemistry values due to temperature, day length, precipitation, constraint and diet amongst other variables. Currently there are no guidelines for veterinarians and rehabilitators to refer to when analyzing blood chemistry values for sick animals. The hope for this research is that it will aide in establishing guidelines for specific circumstances due to environmental stressors. It is hoped that in the future, this study will be used to create values for which veterinarians can ...


Biolojam – The Educational Comic, Stacey Barrie May 2006

Biolojam – The Educational Comic, Stacey Barrie

Senior Honors Projects

BioloJam is a biology comic aimed towards 7th and 8th grade students. The goal of the project was to create an educational resource that students would find entertaining and enlightening. The project is available on the web and is free to use for educational purposes by teachers, students, and parents. There are two comics: the larger, more complicated “Cell Breakout” and the smaller, more conversational “Giraffic Park.” In Cell Breakout, the three heroes are trapped inside a video game in a plant cell, and learn all about cell functions as they try to escape. In Giraffic Park, the trio are ...


Assessment Of Whole Grain Intake And Health Correlates In An Aging Population, Alexis Howard May 2006

Assessment Of Whole Grain Intake And Health Correlates In An Aging Population, Alexis Howard

Senior Honors Projects

Research suggests that whole grain intake may decrease the risk of heart disease, type II diabetes, hypertension, obesity, and many types of cancer. The overall goal of this work is to increase the health status of an older adult population through comprehensive nutrition risk assessment and exposure to tailored nutrition education interventions. This project involved assisting in baseline and post-intervention assessment of the knowledge, attitude, and intake of whole grain foods within a convenience sample of fifty-eight older adults residing in low-income housing sites across Rhode Island. Anthropometry, including height, weight, waist circumference, and blood pressure was measured, along with ...


Analysis Of Distal-Less Gene Expression In Ciona Intestinalis, Michelle Cangiano May 2006

Analysis Of Distal-Less Gene Expression In Ciona Intestinalis, Michelle Cangiano

Senior Honors Projects

Several homeobox-containing genes related to Distal-less (Dlx/Dll) have been isolated from a wide variety of organisms and have been shown to function as developmental regulators. In Drosophila only one Distal-less gene has been identified so far, and in vertebrates many components of the Distal-less family have been characterized. This suggests that, during the evolution of the Chordate phylum, the Dlx genes arose from an ancestral Distal-less gene via gene duplication. Three Dll homeoboxes have been isolated from the protochordate Ciona intestinalis and their clustered arrangement has been described. Since Ciona is regarded as one of the most primitive extant ...


Plasmid Probes For Screening Specific Genes In Large Fragment Dna Libraries, Leah Ferguson Apr 2006

Plasmid Probes For Screening Specific Genes In Large Fragment Dna Libraries, Leah Ferguson

Senior Honors Projects

Heliothis virescens, a member of the lepidopteran family, is of great importance to many people who rely on agriculture as a source of income because it is a pest of many important crops. Because H. virescens feeds on a broad array of hosts including cotton, tobacco, tomato, and soybean it has earned its place as a major nuisance in the United States. Heliothis subflexa is a close taxonomic relative of H. virescens, but the two species differ in that H. subflexa is a specialized herbivore that only feeds on plants in the genus Physalis. Studies have been performed to determine ...


The Sedimentary Environment Below Earth’S Polar Ice Cap As A Microbial Habitat, David C. Smith, Stephanie Forschner, David C. Rowley, Steven D’Hondt Jan 2006

The Sedimentary Environment Below Earth’S Polar Ice Cap As A Microbial Habitat, David C. Smith, Stephanie Forschner, David C. Rowley, Steven D’Hondt

Graduate School of Oceanography Faculty Publications

University of Rhode Island faculty participated in drilling of the polar ice cap to study microbial diversity and adaptation to subsurface life under conditions that may mimic extraterrestrial subsurface conditions.
