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
… 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 …

Response of Three Species of Darters of the Genus Etheostoma to Chemical Alarm Signals From Conspecifics and Congeners
Prior to this study, seven species of darters (Pisces: Percidae) have been identified as having a chemical alarm substance, but it is not known how widespread the chemical alarm substance is within the family Percidae. It has been hypothesized that percid alarm substance is contained in epidermal …

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 …

Friends in Low Places: Responses of a Benthic Stream Fish to Intra-Guild Alarm Cues
… other species that 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 …

Genetic and Life History Characteristics of Venustaconcha Ellipsiformis and Venustaconcha Pleasii (Bivalvia, Unionidae) in the Ozark Plateaus Region
… of the Spring River 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% …

Effects of Trout Introduction on Community Assemblage and Behavior of Native Fish in the Missouri Ozarks
… initiation distance, 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.

Host Specificity of Freshwater Mussels: a Critical Factor in Conservation
… tests confirmed that orangethroat and rainbow darters from the Gasconade River were suitable hosts for the Gasconade River ellipse mussel (38% and 43% transformation success, respectively). I then compared the suitability of orangethroat darters from the Gasconade and Spring River for …
