Item Metabolic responses of adult Bluntnose Minnows (Pimephales notatus) to a range of thermal conditions(Northern Kentucky University) Bauer, Sam; Timmerding, Olivia; Steele, Emily"Climatic temperature fluctuations could have a direct effect on fitness and aerobic scope (AS) of fish. Aerobic scope represents the difference in maximum metabolic rate [MMR] and standard metabolic rate [SMR]. We conducted tests on adult minnows (Pimephales notatus) to monitor their metabolism under four temperatures (13°C, 18°C, 23°C, and 28°C). Fish metabolism was determined using a static- flow respirometry system. Mass-specific metabolic rates of the fish indicated that uniformity in standard metabolic rate, but statistically different aerobic scopes across temperatures. Fish metabolic performance across temperatures indicates the plasticity of this species in a future warmer climate."Item Metabolic scope in the Mosquitofish, Gambusia affinis, as an indicator of climate change impacts(Northern Kentucky University) Steele, EmilyAn organism’s fitness and response to environmental conditions is often tied to its metabolic scope, which can be measured as oxygen consumption. We studied how temperature changes are affecting the metabolic scope of mosquitofish, using measurements of maximum metabolic rate, standard metabolic rate, and aerobic scope. From our data, we have found that the metabolic rates at 23°C are higher than those at 13°C. We have limited results because of design flaws in our respiratory system setup. This will be further investigated once we are able to return to the lab.
