Stage Of Estrous Cycle Influences Behavior After Social Stress, Alexander Jonah Rodriguez
Stage Of Estrous Cycle Influences Behavior After Social Stress, Alexander Jonah Rodriguez
Honors Thesis
Since women are almost twice as likely to develop major depression compared to men, research into this and other potentially debilitating mood disorders using behavioral studies should involve females despite hormonal, physiological, and potential behavior changes due to reproductive cyclicity. Until recently, most studies exclusively used males, thus limiting results of previous research to half of the population. Using adult female C57BL/6N mice as model organisms, we exposed them to novel forms of social stress across five days which encompassed the four-day estrous cycle to determine if the stages of the estrous cycle had an impact on behavior when they …

Influences Of Anti-Bd Bacteria On Amphibians And Their Microbiomes, Emme L. Schmidt
Honors Thesis
The fungal pathogen Batrochochytrium dendrobatidis (Bd) has been threatening amphibian populations across the globe. Recent work has discovered that bacteria isolated from certain populations of amphibians protect hosts from this pathogen. This project focuses on the anti-fungal mechanisms of Serratia marcescens, a species of bacteria isolated from a Costa Rican frog that dramatically inhibited Bd in culture. Wild-type and recombinant S. marcescens was introduced to the microbiomes of a live amphibian host, Acris blanchardi (Blanchard’s Cricket Frog) and then challenged with Bd to examine the protective effects of this bacteria. The experiment includes recombinant S. marcescens with …
