Aaron Madsen and Dr. Keith Crandall, Integrative Biology Astacopsis gouldi has been known to weigh up to 6 kg, and live for as long as 60 years (Horwitz and Hamr, 1988). However, fishing pressure, as well as habitat destruction and pollution have had detrimental effects on A. gouldi populations. The populations of the species in […]

Outcome Testing and the Role of Bilingual Fluency in a Southeast Asian Population
Shelby L. Ferrin and Dr. Michael J. Lambert, Psychology Psychological outcome measures are designed to measure levels of psychological functioning. Scores on such measures may be compared across time to calculate a psychotherapy client’s progress, recovery, or deterioration. Additionally, scores from large populations may be normalized to indicate what therapists designate as levels of clinical […]
The Validation of the Outcome Questionnaire as a Tool of Measurement for Change on the Native American Population in a College Counseling Center
Kärstin L Slade, Elizabeth Richardson and Dr. Michael J Lambert, Psychology In recent years there has been an increasing demand for psychotherapy outcome measures, which can be attributed mainly to the changing health care industry. This, in turn, affects the subsequent demands by corporate purchasers, those in the insurance industry, and government agencies, for evidence […]
Measuring a Highly Religious Population: Development of an Empirical Test for Brigham Young University Students
Marin Turley and Dr. Steven R Thomsen, Department of Communications This research charts the development of a reliable scale that can discriminate differences in religiosity in a highly religious population. Approximately 99% of the more than 30,000 students at Brigham Young University are members of The Church of Jesus Christ of Latter-day Saints, presenting a […]
The Effect of Diathermy and Stretch on the Flexibility of the Hamstring in a Population of 48.4 + 12.3 Years
Sheldon Knight and Dr. Brent Feland, Physical Education Many studies have compared the different variable of stretching: duration of stretch, intensity of stretch, method, frequency, and modalities with stretch (i.e. heat and or cold). Stretching has been shown to improve flexibility, or increase range of motion, injury prevention, enhance muscle performance, promotion of healing, and […]
Utilization of Ancient DNA to Understand the Organization of Social Power in an Ancient Peruvian Population
Christi Embry and Dr. Ray Matheny, Anthropology Molecular biological techniques are allowing researchers to answer questions hidden within the physical archaeological record. DNA analysis of individuals excavated from multiple ancient populations has previously shed light on the origins and genetic affinities of these ancient peoples (5,6). These studies have the power to determine the structure […]
Inferring Demographic Events from Population Level Phylogenies
Steven Woolley and Dr. Keith Crandall, Integrative Biology While I initially proposed to perform a rather thorough comparison of methods designed to infer population level demographic events, during the course of my research, I took a different direction. In order to reliably infer such events, it is first essential to have an accurate phylogeny. Since […]
The Effects of a Restoration Project on the Feeding Habits of Local Trout Populations in the Provo River System
Lance Bastian and Dr. Dennis Shiozawa, Professor of Ichthyology, Integrative Biology In the fall of 1999, the state of Utah began to implement a plan involving several diversions of the Provo River. Over the course of the next several years, there arose a heated debate between the state, local ecologists and local fisherman with regard […]
Population Structure of the Cuttlefish Sepia Officinalis from the North Atlantic-Mediterranean Region
Mark Joseph Nolte and Drs. Keith Crandall, Microbiology and Molecular Biology, Integrative Biology; Marcos Pérez-Losada, Integrative Biology An understanding of the relatedness of a population of organisms, or their phylogeny, combined with knowledge of that population’s geographical distribution, can illuminate which geographic forces and events may have played a role in forming the “family tree” […]
Overcoming Anthropogenic Impediments of Reintroduced Bighorn Sheep Populations in North-central Utah
Loren Chase Introduction Bighorn sheep (Ovis canadensis) were historically abundant in many places in Utah, however, when the area was settled, humans brought with them many causes for bighorn extermination. Unregulated hunting, competition for resources by livestock, reduced water availability, reduce range quantity, home range encroachment, and the lungworm/pneumonia complex are all major reasons as […]
