Development, Growth, and Behavioral Ecology of Walleye as Influenced by Sublethal Exposure to Dietary Selenium
A decline in the walleye Stizostedion vitreum sport fishery in lower Lake Oahe, South Dakota, was documented in the early l 980's and has since been attributed to poor natural reproduction and/or recruitment. Contaminants are highly suspected in lower Lake Oahe because of the low natural …

Effects of Sublethal Copper Exposure on Escape Behavior and Growth of Rana pipiens Tadpoles
This research is designed to test how sublethal exposure to copper affects tadpole predator-escape behavior and how quickly tadpoles recover. After exposure, tadpoles were separated. Escape behavior was recorded for two-thirds of exposed tadpoles while one-third of the exposed population was …

The effects of temperature on the sensitivity of Daphnia pulex to two simulated industrial effluents
… C. Mixed age adult Daphnia were pre-exposed to sublethal levels (LC10) of the SBM and the ARM at both 10 and 20 C and then subjected to t's above ambient of 5.4, 8 and 12 C for one hour. One other group received sublethal exposure only and the controls were maintained only in dilution water. …

Sublethal Hepatic Pathology and Evidence of Intranuclear Effects of the Cyanobacterial Toxin Microcystin -Lr
… by Microcystis aeruginosa. The pathology of sublethal exposure is not well characterized. MCLR immunohistochemistry (MCLR-IHC) studies indicate that the nucleus may be a target of MCLR. Balb/c mice were given one sublethal dose at 45 mug/kg or repeated daily doses for 2, 4 and 7 days. At 2 …

Waggle Dance Your Own Way: Individuality, Network Structure, and an Herbicide Stressor in Recruitment, Foraging, and Neurobiology in the Honey Bee (Apis mellifera L.)
… its utility as a study system for understanding sublethal behavioral effects of pesticide exposure. This dissertation presents three novel studies of the waggle dance. In the first, we asked whether consistent inter-bee differences (i.e., individuality) in a waggle dance distance - duration …
