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 …

Experience With Chemical Cues Influences Subsequent Behavior of Rainbow Darters, Etheostoma Caeruleum
… 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 standard …

Effects of Trout Introduction on Community Assemblage and Behavior of Native Fish in the Missouri Ozarks
… a proxy of wariness, of rainbow darters, Etheostoma caeruleum, and orange throat darters, Etheostoma spectabile. The increased wariness observed in these species in trout streams could have long-term fitness consequences for these species.

The Effects of a Reservoir on Genetic Isolation in Two Species of Darters
… 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 individuals of each species were …

Friends in Low Places: Responses of a Benthic Stream Fish to Intra-Guild Alarm Cues
… are in the same prey-guild. Rainbow Darters (Etheostoma caeruleum) are benthic fish that co-occur with native Ozark Minnows (Notropis nubilus), recently-introduced Western Mosquitofish (Gambusia affinis), and native Oklahoma Salamanders (Eurycea tyrnerensis), all of whom are vulnerable to the …

Genetic and Life History Characteristics of Venustaconcha Ellipsiformis and Venustaconcha Pleasii (Bivalvia, Unionidae) in the Ozark Plateaus Region
… mussels as V. ellipsiformis. Rainbow darters (Etheostoma caeruleum) were an important natural host for V. pleasii in the James River (White system), but not for V. ellipsiformis, which utilized orange throat darters (E. spectabile) in the Spring River. In laboratory tests, 31% of V. pleasii …

Speciation and the evolution of male breeding coloration in darters
… similar species: the rainbow darter (Etheostoma caeruleum) and the orangethroat darter (E. spectabile). First, I quantified variation in male breeding coloration across multiple populations of E. caeruleum and E. spectabile using digital photography and image processing software. Male …

Behavioral and genomic patterns of evolution during speciation via reproductive and agonistic character displacement
… Oligocephalus: the orangethroat darters clade (Etheostoma: Ceasia) and the rainbow darter (Etheostoma caeruleum). I found behavioral evidence for male-driven RCD and ACD between multiple orangethroat species and their respective sympatric rainbow darter populations. When orangethroat and rainbow …
