David Patty and Dr. John SK Kauwe, Biology Alzheimer’s Disease, the most common form of dementia, affects nearly 6 million Americans. Its effects on the individual range from mild impairment of memory to the complete destruction of the victim’s identity and their ability to perform everyday tasks. They become a heavy burden on their family, […]
Phenotypic Divergence of Boldness in Brachyrhaphis Fishes
Joseph Nelson and Dr. Jerald B. Johnson, College of Life Sciences, Department of Biology The general public has a fairly good understanding of evolution and how physical characteristics of a species can change to adapt to environmental inconsistencies. In times of drought, flood, or other natural stress that commonly occur in nature, animals must adapt […]
Alzheimer’s Disease and Mitochondrial Genome Copy Number
Miles McKee and Dr. John Kauwe, Biology The purpose of this research project was to identify genetic variation, or more specifically variation in the average number of mitochondria per cell, and determine how these variations relate to risk for Alzheimer’s disease (AD). The project started off with a measurement of the ratio of mitochondrial genome […]
Molecular Diversity Compared to Associated Morphological Differences Between Two Species of Southern Chilean Crabs
Andres Mallipudi with Erwin Barria, Carlos G. Jara, and Keith A. Crandall Abstract The biologically diverse region of Patagonia is under constant threat of urban development from both external and internal sources. Gaining a thorough understanding of the ecological roles of this area’s organisms is essential to preserving Patagonia’s rich biodiversity. Researching the differences between […]
Search for Genomic Factors that Influence Cerebrospinal Fluid Levels of YKL40, a Novel Biomarker for Alzheimer’s Disease
Mo Lee and Dr. John S.K. Kauwe, Biology Department Alzheimer’s disease is the most common form of dementia in the United States. It is a complex neurodegenerative disorder featured by gradual onset and progression of memory loss combined with deficits in executive functioning, language, visuospatial abilities, personality, behavior and self-care. There are basically two types […]
The Evolution of Color Vision in Dragonflies and Damselflies (Odonata)
Kelsy Johnson and Dr. Michael F. Whiting, Biology Department Opsins are the genes present in the eye that are responsible for color vision in all animals (Briscoe et al., 2001). Insect vision is particularly interesting because they are able to see different wavelengths of light due to the number and types of opsins present in […]
Phylogeny of Ensifera (Orthoptera) and the Evolution of Acoustic Communication
Jessica Jensen and Dr. Michael Whiting, Biology Ensifera is an insect suborder within the order Orthoptera that includes insects such as katydids and crickets. The evolutionary history of Ensifera is largely unknown, and there is no consensus on the phylogenetic relationships among families within Ensiera. A large part of this is due to inadequate character […]
Characterization of 10 polymorphic microsatellite loci in the South American lizard Liolaemus fitzingerii with cross-amplification in L. chehuachekenk
Nathan Hanna and Dr. Jack Sites, Biology Department Liolaemus is a genus of lizards that is very common in South America, particularly the southern regions. Distinguishing differences between separate species within the Liolaemus genus has been an ongoing pursuit, one in which Jack Sites and his lab have been extensively engaged. Liolaemus chehuachekenk is a […]
Using Carbon and Nitrogen Stable Isotopes in Manure, Hair and Blood to Predict Recovery from Gastrointestinal Colic in Horses
Jesse Caitlin Alexis Ford and Professor Beverly Roeder, Biology Colic, or abdominal pain, is one of the most prominent clinical signs present in many equine diseases. Gastrointestinal (GIT) colic is one of the leading causes of death in horses. The research initiated here at BYU, as a result of earning an ORCA grant, aims to study this […]
Perfect Pets and Delicious Delicacies: Resolving the Phylogenetic Relationships within Anomura (Decapoda)
Maren Ettinger and Dr. Keith Crandall; Biology Department The purpose of phylogenetics is to understand how organisms are related and how they have evolved. My project focused on understanding the relationships within the Anomura infraorder of the Decapoda. Anomurans encompass a variety of economically important and morphologically diverse crustaceans. They include hermit crabs, mole crabs, […]
