Abstract: <p>Opioid drugs are among the microcontaminants that are discharged with domestic wastewater into the aquatic environment with the potential to affect the development and reproductive capacity of aquatic organisms. To study the effects of exposure of fish to opioid drugs, Japanese medaka (Oryzias latipes) were exposed over a full life cycle to environmentally relevant (i.e. ng/L)… more Full Text: Effects of Opioids on the Development and Reproductive Capacity of Japanese Medaka, Oryzias latipes A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Master of Science in the Faculty of …

Abstract: <p>Exposure of pre-metamorphic amphibians to neonicotinoid insecticides may be contributing to the global decline in amphibian populations. In this study, anuran embryos and tadpoles of the African clawed frog (Xenopus laevis) and the North American leopard frog (Lithobates pipiens) were used to determine the effects of embryonic exposure to neonicotinoids. In addition, Xenopus was used to… more Full Text: Effect of the neonicotinoid imidacloprid on embryogenesis and anuran survivorship in frog virus 3 infected tadpoles A thesis submitted to the Committee of Graduate Studies in partial fulfillment of the requirements for the degree of Master of Science in …

This dissertation focuses on three experiments designed to test the hypothesis that plastic ability is limited by energetic constraints. Chapter 1 provides a general introduction to phenotypic plasticity research and the theoretical costs and limitations affecting the expression of plastic traits… more Full Text: CONSTRAINTS ON PHENOTYPIC PLASTICITY IN RESPONSE TO PREDATION RISK: CARRYOVER EFFECTS, MATERNAL INVESTMENT, AND THE STARVATION-PREDATION RISK TRADE-OFF A dissertation submitted to the Committee on Graduate Studies in partial fulfillment of the …
