Exploration Of Sonic Hedgehog Gene Expression In Fathead Minnows (Pimephales Promelas), Brooke Renee Greiner
Exploration Of Sonic Hedgehog Gene Expression In Fathead Minnows (Pimephales Promelas), Brooke Renee Greiner
Undergraduate Honors Theses
Pollutants, as a result of wastewater treatments, have been shown to have negative impacts on aquatic ecosystems. To better understand the possible consequences caused by effluents on ecosystems, it is important to examine ecotoxicology data. One of the most commonly used species for water quality testing is the fathead minnow, Pimephales promelas. Ecotoxicology can then be taken one step further to understand the effects of pollutants on a molecular level. Previous research had identified effluents as causes for abnormal minnow fin morphology. In order to collect additional data on development, tanks with fathead minnows were placed at the Charleston …
Median Fin Patterning In Bony Fish: Caspase-3 Role In Fin Fold Reabsorption, Kaitlyn Ann Hammock
Median Fin Patterning In Bony Fish: Caspase-3 Role In Fin Fold Reabsorption, Kaitlyn Ann Hammock
Undergraduate Honors Theses
Fish larvae develop a fin fold that will later be replaced by the median fins. I hypothesize that fin fold reabsorption is part of the initial patterning of the median fins, and that caspase-3, an apoptosis marker, will be expressed in the fin fold during reabsorption. I analyzed time series of larvae in the first 20-days post hatch (dph) to determine timing of median fin development in a basal bony fish - sturgeon- and in zebrafish, a derived bony fish. I am expecting the general activation pathway to be conserved in both fishes but, the timing and location of cell …
Effects Of Turbidity On The Vision And Behavior Of Longear Sunfish, Lindsey Denea Caudle
Effects Of Turbidity On The Vision And Behavior Of Longear Sunfish, Lindsey Denea Caudle
Undergraduate Honors Theses
Fish are known to use vision in many essential behaviors, including foraging, intraspecific communication and predator avoidance. Turbidity is one of the many environmental factors potentially affecting vision quality. I examined the behavior of interacting conspecific fish in varying levels of turbidity to determine how this environmental variable affects vision and behavior. Experiments were designed to observe how longear sunfish, Lepomis megalotis, reacted to visual cues - in this case a conspecific fish in a glass jar - in the presence or absence of turbidity. My hypothesis is that sunfish will display territorial behavior when introduced to another fish …
