The Effects Of White-Nose Syndrome On Cave-Dwelling Bats During Their Pre-Hibernation Season In Eastern Nebraska, Maggie Bockart

Theses/Capstones/Creative Projects

White-nose syndrome (WNS) is currently the leading cause of death to North American bats and was first documented in the United States in 2006 on the East Coast. Infection with the fungus Pseudogymnoascus destructans (Pd) causes bats to arise from hibernation with unnecessary frequency, leading to depletion of fat reserves that are imperative for extended periods of torpor. In October 2014, biologists surveyed the activity levels of bats at Fontenelle Forest in eastern Nebraska using acoustic detectors and determined what species of bats were present and their relative abundance before being exposed to WNS. By returning to the …

Predictors Of Testosterone In Male African Elephants (Loxodonta Africana), Kaitlyn Campbell

UNO Student Research and Creative Activity Fair

Male African elephant (Loxodonta africana) populations in zoos suffer from a range of reproductive complications. In particular, insufficient testosterone production can have a detrimental effect on spermatogenesis and fertility. Few studies have explored the potential social, environmental, physiological and physical factors that influence bull testosterone levels in a zoo environment. The present study will collect endocrine and metabolic information from weekly fecal and blood serum samples taken over the course of the six-month study period. Social and environmental data will be collected in a survey provided to the institutions. Results will highlight the key factors contributing to fluctuations in testosterone …

Juvenile Hormone Mediation In An Insect With Parental Care Behavior, Jessica M. Rodino

UNO Student Research and Creative Activity Fair

Juvenile hormone (JH) is a well-known catalyst for hormonal processes in insects. However, the role of JH in insects that exhibit parental behavior is unknown. We investigated the influence of JH on parental behavior in the burying beetle (Nicrophorus orbicollis). In the first experiment, we manipulated the JH production of females via the administration of varying doses of fluvastatin sodium immediately following oviposition. We found that with increasing fluvastatin dosage, the total mass of offspring and number of offspring decreased while at the same time less of the food source was consumed. These results suggest a link between …

Contextual Fear Learning And Memory In Alternative Stress Coping Styles, Matthew R. Baker, Ryan Y. Wong

UNO Student Research and Creative Activity Fair

Animals frequently must overcome stressors, and the ability to encode and recall these salient experiences is essential to an individual’s survival. Across many taxa, studies have documented two alternative stress coping styles (proactive and reactive) that differ in behavior, cognition, stress physiology, and underlying neuromolecular mechanisms. The role of stress in cognitive traits (e.g. learning and memory) has been well documented, however, the influence of an animal’s stress coping style on learning and memory capabilities is only beginning to be understood. Here, we developed a contextual fear learning paradigm to characterize learning and memory differences between proactive and reactive stress …
