Robert Adams and Dr. Robert Conlee, Health and Human Performance Oxygen is the essential element in the air we breathe. The concentration of oxygen is constant in the atmosphere at approximately 21%. However barometric pressure is not constant throughout the atmosphere. The barometric pressure measures the amount of pressure the particles in the atmosphere exert […]
Internal Transcribed Spacer Regions of Nuclear Ribosomal DNA as a Tool For Phylogenetic Reconstruction
Melissa E. Hardy and Dr. Keith Crandall, Zoology Phylogenetic trees are an estimate of genealogical relationships among groups of organisms. They are reconstructed by analyzing homologous nucleic acid sequences from different organisms and deriving an evolutionary relationship from the similarity in sequences. Ribosomal DNA consists of gene clusters tandemly repeated on a chromosome. Each cluster […]
Genetic Analysis of the Mountain Whitefish, Prosopium Williamsoni
Daniel C. Hambleton and Drs. Dennis K. Shiozawa and R. Paul Evans, Zoology Although currently part of the Bonneville Basin system, Bear Lake was once connected to the Snake River system of southeastern Idaho 40,000 years ago. Subsequent geological activity disrupted the exchange of fish populations between the Snake River and Bear Lake. We anticipated […]
Evolutionary Relationships of Genera in the Lizard Family Iguanidae
Bruce W. Christensen and Dr. Jack W. Sites, Zoology The family Iguanidae contains eight living genera of large, herbivorous lizards that by virtue of their size occupy important ecological niches wherever they are found. They are important elements of the food web, both as seed dispersers and prey for other animals, including humans (1). Of […]
Development of an Antibody to Utx Protein
Joanna L. Cheatham and Dr. Randy L. Bennett, Zoology Tribolium castaneum, red flour beetle, is an organism whose development is being studied and compared to that of Drosophila melanogaster. The particular goal of this study was to develop an antibody to Tribolium’s UTX protein, so it’s expression may be monitored during embryonic and larval development. […]
Modeling Dipyrenylpropane
Steven Bray and Professor David Busath, Department of Zoology 1,3-di(1-pyrenyl)propane(hereinafter dipyrenylpropane) has proven very useful as a fluorescence probe in determining fluidity and monitoring phase transitions in biological membrane systems.1 By virtue of its structure, dipyrenylpropane may fluoresce light in an excimer or a monomer configuration. Each configuration fluoresces light at a different wavelength, thus […]
Phylogeny of Siphonaptera in Relation to Mecoptera And The Snow Fleas Using Molecular Data From The Mitochondrial Gene Cytochrome Oxidase ii
Sonia Bake and Dr. Michael Whiting, Zoology Purpose The intent of this study is to determine the phylogeny of the order Siphonaptera (fleas) and their relationship to the order Mecoptera (scorpion flies) including the Boreidae family (snow fleas) which have traditionally been placed with the scorpion flies. A study is being conducted using molecular data […]
THE EFFECTS OF WHITE BASS (MORONE CHRYSOPS) PREDATION ON JUVENILE JUNE SUCKERS (CHASMISTES LIORUS)
Michael J. Whitney and Dr. Mark C. Belk, Zoology We estimated the vulnerability of juvenile June suckers to predation by a growing cohort of juvenile white bass. Also, habitat preference of juvenile white bass (open versus vegetated habitats) in the presence and absence of adult white bass was determined experimentally. Juvenile white bass preferred vegetated […]
ANDROGEN REGULATION OF CALBINDIN-D28K IN RAT HYPOTHALAMIC TISSUE DURING PRENATAL DEVELOPMENT
Melanie A. Watson and Dr. Edwin Lephart, Zoology Calbindin-D28K is a calcium-binding protein that serves a potentially important role in both the development and function of the central nervous system (CNS). Previous studies indicate the dimorphic expressions of calbindin within the medial basal hypothalamus (N4BH), supporting its putative importance in the neurogenesis of sexually dimorphic […]
RAPD ANALYSIS OF THREE BREEDING LINES IN HORSES
Gregory B. Tilton and Drs. Robert L. Park & Jerran Flinders, Animal Science The focus of this project was two-fold. First, to test whether RAPDS, a genetic marker finding technique, could be used to find markers in three separate sire/offspring groups of horses. Second, to determine whether we could use RAPDs to produce a similarity […]
