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 …
