Food Habits and Biology of Stonerollers (Campostoma) in Southwest Missouri
… 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 a microhabitat …

Fish Community Assembly in the Forest River, North Dakota, and Resolution of Campostoma Species Presence
… aspect I examined was the presence of the genus Campostoma. In this aspect, I investigated the Campostoma species that were present historically and documented the species that currently inhabit Red River waters in North Dakota. The second aspect of my work was to study the fish community …

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 …

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
Campostoma anomalum, a common minnow found in streams throughout the eastern U.S., was investigated as a potential bioindicator for heavy metal pollution. This species is a benthic algivore and detritivore that is exposed to heavy metals that accumulate in the sediment. It was hypothesized that …

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
<p>Nutrient and benthic algal biomass relationships can guide numeric nutrient criteria development in lotic systems. However, herbivorous macrograzers may confound this relationship by reducing the slope of the positive relationship between nutrients and periphyton biomass in streams. I conducted …

Movement of Forage Fishes in a South Dakota Stream
… Semotilus atromaculatus, Rhinichthvs atratulus, Campostoma anomalum and Catostomus commersoni were investigated in an eastern South Dakota stream for a period of one year. Electrofishing, fin clipping and a multiple census method were employed. Population structures were estimated for each …

Life History and Distribution of the Tennessee Dace (<em>Phoxinus tennesseensis</em>) in Northeast Tennessee.
… atromaculatus</em> (creek 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> …

Cheating and Selfishness in Reproductive Interactions among Nest Associative Cyprinids
… 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 located in the …

Distribution and Life History of Chrosomus sp. cf. saylori in the Upper Clinch River Watershed, Virginia
… niche roles. I observed a nest association with Campostoma anomalum. Gonad weight was lower for C. sp. cf. saylori than closely-related congeners. Together, this information indicates that C. sp. cf. saylori are narrowly distributed and populations are small, fragmented, and of questionable …

Field- and laboratory-determined behavioral avoidance and gill histological alterations of fish in response to acidic and alkaline pH conditions
… 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 in acidic …

Longitudinal Variation in Fish Community Along the Upper Green River Below the Green River Lake
… and mean daily temperature (p = 0.002), between Campostoma oligolepis abundances and mean daily temperature (p = 0.043) and between Etheostoma zonale and % gravel. Finding only four significant linear relationship between species abundances and environmental variable suggest other environmental …

Investigating the Role of Long Distance Dispersal in the Response of Stream Fishes to Urbanization
… 12mm HPT PIT tags and included a specialist, <em>Campostoma oligolepis </em>(n=189 urban site, 200 rural site) and a generalist, <em>Lepomis auritus</em> (n=136 urban site, 182 rural site). Three resampling instances for each site were conducted between September of 2016 and February 2017 with a …

Differential stability of spawning microhabitats of warmwater stream fishes
… 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 tracer particle …

Investigating Reproductive Phenology and Alloparental Care in Leuciscid Fishes using Niche Theory Approaches
… 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 involved in …
