Mahurin Honors College Capstone Experience/Thesis Projects
In the Barren River Lake of south central Kentucky, native white bass, Morone chrysops, has experienced a decline in population after the introduction of yellow bass, Morone mississippiensis. These species are competing for resources due to an overlapping diet, likely contributing to the decline of the white bass. To explore this hypothesis, I examined the stomach contents and otoliths of white and yellow bass caught during their spawning time in spring 2012. There were 40 yellow bass and 128 white bass collected in Barren River upstream of Barren River Lake. Analysis of stomach contents revealed that both white and …

Assessing Wavelength Discrimination Abilities In The Zebrafish (Danio Rerio) Using Appetitive Choice Discrimination Learning, Tim Thornberry
Mahurin Honors College Capstone Experience/Thesis Projects
In the past few decades, the zebrafish has become a popular vertebrate model in various fields of research, especially visual neuroscience, where the versatile zebrafish model has been used for anatomical, physiological, genetic, developmental, and behavioral research. Anatomical and physiological studies have shown that the zebrafish has the necessary mechanisms required for color vision. However, to date, there is no evidence that zebrafish behavior is regulated by color vision. This project used an appetitive choice discrimination paradigm to assess the ability of the zebrafish to modify its behavior based exclusively on color cues. Subjects were conditioned to associate a food …
