Fish Ladders Designed for Drop Culverts and Central Stoneroller Ecology Across a Latitudinal Gradient
… body condition, and phenology of Central Stoneroller across three latitudes. The final fish ladder design was based on a Denil-type fish ladder and consisted of 14 evenly spaced flat-top baffles every 15.2 cm at 45° angles to the slope. We tested the fish ladder under controlled and field …

Campostoma anomalum Roanokense, a new subspecies of the stoneroller minnow in the James and Roanoke rivers
Campostoma anomalum roanokense, a new subspecies of C. anomalum in the James and Roanoke Rivers of Virginia, West Virginia, and North Carolina is compared to C. a. kanawhanum, the most closely related form, and to other similar forms. Three races of C. a. roanokense: a. South Fork Roanoke River …

The Central Stoneroller, Campostoma Anomalum, as an Indicator of Heavy Metal Contamination Using Otolith Age Determination and Growth Analysis
… It was hypothesized that young-of-the-year stonerollers from an impacted site would exhibit a reduced growth rate compared to those from an upstream reference site. A lab experiment revealed that alizarin red S will impart a violet-red mark in stoneroller otoliths that can be viewed with a …

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
… 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 enzyme activities of Na+, …

Life History and Distribution of the Tennessee Dace (<em>Phoxinus tennesseensis</em>) in Northeast Tennessee.
… chub) and <em>Campostoma anomalum</em> (central stoneroller). With 1 to 10 females, 20 to 45 male dace gathered over the nest. <em>Phoxinus tennesseensis</em> populations have 4 age classes. The normal life span of the dace was about 2 years with 1<sup>st</sup> year fish constituting a majority …

Fish Community Assembly in the Forest River, North Dakota, and Resolution of Campostoma Species Presence
… Red River basin to determine presence of central stoneroller, Campostoma anomalum, and largescale stoneroller, C. oligolepis because both species have been reported in the basin historically. Campostoma sp. were found at five sites. These specimens and museum specimens collected during previous …

Food Habits and Biology of Stonerollers (Campostoma) in Southwest Missouri
… taxonomic separation of two sympatric species of stoneroller minnows, Campostoma oligolepis and C. anomalum pullum, were investigated in Southwest Missouri. The only food habit difference between the species was the larger amount (x=5%) of inorganic matter ingested by C. a. pullum. This indicated …

Cheating and Selfishness in Reproductive Interactions among Nest Associative Cyprinids
… Given their GSI patterns and behavior, central stonerollers Campostoma anomalum may be cheaters in the interaction. I used multiple experiments to test for the selfish-herd effect, the role of parental care, and how relative risk influences reproductive decisions of associates. Most eggs were …

Field- and laboratory-determined behavioral avoidance and gill histological alterations of fish in response to acidic and alkaline pH conditions
… diversity and an increased dominance of the stoneroller (Campostoma anomalum), which displaced more sensitive species. Laboratory avoidance studies, utilizing a steep-gradient trough apparatus, were used to investigate the potential role of avoidance behavior that may alter fish distributions …

Differential stability of spawning microhabitats of warmwater stream fishes
… and high turbulence. The pit-building central stoneroller (Campostoma anomalum) was distinct in its usage of areas with high velocity and turbulence, gravel sized substrate, and low embeddedness. Stability of each guild's spawning microhabitats was empirically evaluated through analysis of …

Experience With Chemical Cues Influences Subsequent Behavior of Rainbow Darters, Etheostoma Caeruleum
… exposure to nonpredatory control stimuli (stoneroller and blank) resulted in random habitat choice after 24 hours. (b) Habitat choice of darters exposed to conspecific alarm pheromones (in either habitat) was random after 24 hours. (c) Darters were attracted to the rock habitat (but not the …

Long Term Hydrologic Effects on Stream Health from Residential Development Patterns
… pool species habitat (represented by the central stoneroller and smallmouth bass, respectively). Overall, increased development has been found to have a negative impact on stream health. This impact should be considered in any future expansion of the Roanoke suburbs into this watershed.

Effects on Campostoma oligolepis Digestive Morphology and Gut Microbiota Composition across a Gradient of Urbanization
<p><em>Campostoma oligolepis</em>, the Largescale Stoneroller, is a species of minnow native to northwest Georgia. This study investigated the impacts of urbanization on gut length and gut microbiota community composition in <em>C. oligolepis</em> from four small watersheds within the Etowah River …

Investigating Reproductive Phenology and Alloparental Care in Leuciscid Fishes using Niche Theory Approaches
… White Shiner Luxilus albeolus, Central Stoneroller Campostoma anomalum, Creek Chub Semotilus atromaculatus, and Blacknose Dace Rhinycthys atratulus. I applied Hutchinsonian niche theory with respect to hydrology and water temperature to define the reproductive phenology of each species …

Effect of Macrograzers (Campostoma spp. and Faxonius spp.) on Periphyton in Ozark Streams with Considerations Given to Macrograzer Biomass, Phosphorus, and Season: Mensurative and Manipulative Studies
… a mensurative field study to determine if stoneroller and crayfish abundance related to algal biomass at varying nutrient concentrations and manipulated macrograzer presence with electrical exclosures in streams to examine macrograzer effects on algal biomass and understand whether these …
