Yamada, Kaylene | Comparing Tollerance of Neotoma Lepida on Native Versus Novel Toxic Diets | Herbivorous animals often ingest plants that protect themselves with chemicals, and these toxins typically differ in composition from plant to plant. For instance, juniper (Juniperus osteosperma) is dominated by terpenes, such as α-pinene, whereas creosote bush (Larrea tridentata) contains a cockta... | | 2017 |

Roestenburg, Jessica | Testing the Perceptual Salience of Spectral Content in Zebra Finch Song | Birds actively adjust the resonance properties of the upper vocal tract during singing, which results in specific harmonic structures of song elements. To what degree upper vocal tract filtering is relevant for the perceptual salience of song is poorly understood. This research utilizes (1) a biolog... | | 2018 |

Pearson, Cassidy | Major Urinary Protiens as a signal of genetic Quality and Infection status | The Hamilton-Zuk hypothesis suggests that susceptibility to infectious disease is so important that many physical traits, particularly secondary sexual characters, will evolve to signal genetic quality for resistance to prospective mates. We expanded upon this theory using the house mouse (Mus muscu... | | 2018 |

Ellis, James H. | Refractory status epilepticus and chronic kidney disease in a large pedigree due to a variant in the mitochondrial encoded trna phenylalanine (MT-TF) gene | Mitochondrial disorders present with a wide spectrum of neurological manifestations. Clinical syndromes are described largely by phenotypic indicators. Epilepsy is a common but not universal feature. Myoclonus epilepsy with ragged red fibers (MERRF) is a common clinical syndrome that presents with e... | | 2018 |

Beseris, Ethan | Biological impact protection in human facial hair | Our study investigated selective mechanisms that influenced the evolution of facial hair in human males (Homo sapiens). Beards are often perceived as an indicator of masculinity and social dominance in men, suggesting that they may play a role in male contest competition. Some authors propose that t... | | 2018 |

Mercer, Marianne | Establishing a System for Structure-Function analysis of the Novel Role that NUP153 Plays in Nuclear Assembly | In mitosis, equal partitioning of DNA between daughter cells requires an integrated series of events. At the start of anaphase the chromatin separates and forms two chromatin discs. This chromatin is then targeted by nuclear membrane proteins and membrane to form the nuclear envelope. These membrane... | | 2018 |

Fackler, Anderson N. | Identification of Kin-20 and UNC-119 Knockout suppressors associated with neuronal development and maintenance in C. elegans | Neurons comprise the nervous system-the essential signaling and communication system for nearly all multicellular organisms. To coordinate cells across an entire organism, they must grow to be relatively long. Therefore, neurons extend axons from the cell body. Immature neurons extend growth cones a... | | 2018 |

Ong, Elaine | Identifying Natural Genetic Modifiers of Apoptosis and Retinal Degeneration | Apoptosis, or cell death, is an integral part of many diseases such as neurodegeneration, retinal degeneration, and cancer, yet it is unclear how apoptosis varies among individuals in a population. Retinitis pigmentosa (RP) is a retinal degeneration disease characterized by phenotypic heterogeneity ... | | 2018 |

Smith, Sarah | Effects of Mitochondrial Mobility on Astrocyte Function | Within the brain, astrocytes provide support and influence the excitability of neurons by regulating the extracellular levels of potassium (K+) and glutamate. These glial cells play a vital role in neural homeostasis by regulating the concentration of neurotransmitters at the synapse, therefore modu... | | 2018 |

Bell, Marisa | Characterization of Polyphenols in I. Umbellifera | Secondary metabolites in plants, including polyphenolics, may be responsible, in part, for diversity in the tropics. Variation in chemical defense among species of trees encourages specificity in herbivorous insects. Due to the short lifespan of insects compared to trees, diversity in chemical defen... | | 2018 |
