Monty A. Hawkins and Drs. Jack W. Sites Jr. and Brice P. Noonan, Biology The lesser tree frog (Hyla minuta) is found in abundance throughout most of South America. Earlier studies have suggested that this taxon includes populations which differ significantly in ecological (Cardoso & Haddad, 1994) and morphological (Kaplan, 1994) characteristics (fig 1), and […]
Survey of Nematocerous Flies (Diptera) of Maupiti, French Polynesia
Limb Hapairai and Dr. C. Riley Nelson, Integrative Biology 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 […]
Do Stable Isotope Turnover Rates in Ectotherm Tissues Change with Temperature?
Joseph Franckum and Professor Kent Hatch, Integrative Biology 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 […]
The Orthopteran Mitochondrial Genome and The Evolution of Genes
J. Daniel Fenn and Dr. Michael F. Whiting, Integrative Biology The insect order Orthoptera contains the common name groups of Grasshoppers, Katydids and Crickets. We sequenced the entire mitochondrial genome of the Mormon Cricket (Anabrus simplex). Within this genome we found interesting evidence relating to the organization and evolution of mitochondrial genomes. In particular we […]
Speciation by Reproductive Isolation
Ian Dawson and Dr. Jerry Johnson, Integrative Biology Significance of Research The Ecological Speciation Hypothesis is a controversial explanation for how new species form. Although the idea is gaining momentum, there have been very few empirical tests of this model. Hence, our research is very timely and addresses what could be a common process by […]
Effects of Fasting On Oxygen Stable Isotope Ratios
Bryt Christensen and Professor Kent Hatch, Integrative Biology The purpose of my project was to see if fasting has any effect on oxygen stable isotope ratios. Oxygen isotopes are molecules of oxygen that weigh more or less than normal oxygen 16 because they have more or less electrons. Stable isotopes are used as a scientific tool […]
What Is In Your Picnic Basket
Hailey Billings and Dr. Beverley Roeder, Integrative Biology My project made inroads in the field of wild animal nutrition using stable isotope ratios to reconstruct diets in free ranging American Black Bears. This information will help develop diets that improve health and reproduction, and aid prevention of diseases and ailments such as obesity, arthritis, allergies […]
Effects of Inundation Length On Fairy Shrimp
Tammy Behunin and Professor Russell Rader, Integrative Biology Phyllopods (fairy shrimp, tadpole shrimp, and clam shrimp) are the species that best characterize freshwater rock pool communities around the world because of their unique adaptations to temporary conditions. The fairy shrimp, Branchinecta packardi, is one of the most abundant animals in temporary rock pools of the Colorado Plateau. […]
Growth Rates, Diet, and Distribution of Pictetiella expansa, a Rare Rocky Mountain Perlodidae Stonefly (Plecoptera)
Sarah Walker and Dr. C. Riley Nelson, Biology The stonefly Pictetiella expansa has been acknowledged as a species since the 1920s, yet little is known about this rare species of Perlodidae stonefly. The purpose of our study was to document the growth rates and feeding behaviors of Pictetiella expansa in the American Fork River as […]
Testing Nuclear Primers
Nathaniel Ralston and Dr. Keith Crandall, Biology Crustaceans are some of the richest multi-cellular animals in the world in terms of species. Within the crustaceans the decapods are chief in species numbers and diversity with over 15,000. Among these are the very familiar and well-known species, such as crayfish, shrimp, and crabs, although there also […]
