Assessing the Effects of Temperature, Feeding Status, and the Microbiome on the Maximal Activities of Several Enzymes Important to Energy Production and Ammonia Detoxification in the Intestines of Teleost Fish
… of three species of teleosts: the goldfish, rainbow darter and central stoneroller. In warm-acclimated goldfish, intestinal and branchial tissues were more responsive to feeding, while renal tissues were not affected by digestion or thermal acclimation. This was reflected in the maximal …

Experience With Chemical Cues Influences Subsequent Behavior of Rainbow Darters, Etheostoma Caeruleum
… two sets of experiments to determine whether rainbow darters, Etheostoma caeruleum, alter their behavior following experience with predatory and conspecific stimuli. First, I tested whether darters could learn to associate the color of a predator model with danger. In one experiment, I used …

Behavioral and genomic patterns of evolution during speciation via reproductive and agonistic character displacement
… in a diverse clade of stream fishes called darters (Percidae: Etheostominae). I focused on two groups in the subgenus Oligocephalus: the orangethroat darters clade (Etheostoma: Ceasia) and the rainbow darter (Etheostoma caeruleum). I found behavioral evidence for male-driven RCD and ACD …

The Effects of a Reservoir on Genetic Isolation in Two Species of Darters
… the genetic diversity of two species of darter, the rainbow darter <i>Etheostoma caeruleum</i> Storer and the Highland Rim darter <i>Etheostoma kantuckeense</i> Ceas and Page, was determined from populations inhabiting the Barren River Lake drainage basin. Between ten and twenty-six …

Speciation and the evolution of male breeding coloration in darters
… speciation is a topic of much debate and study. Darters, a species-rich clade of freshwater fishes that exhibit widespread sexual dichromatism, may represent a prime example of speciation by sexual selection. I investigated mechanisms of sexual selection and reproductive isolation in two closely …

Predator Recognition Learning in Rainbow Darters (Etheostoma Caeruleum)
I investigated whether rainbow darters (Etheostoma caeruleum) could learn to associate cues from an unfamiliar predator with a known fright stimulus (darter alarm cues) through the process of classical conditioning. Darters in the experimental group (n=32) were trained using their alarm cues paired …
