Freckled Darter (Percina lenticula) And Other Fishes’ Usage Of Wood Pile Habitat
… species and entire species assemblages. <em>Percina lenticula</em> is a species of special concern in the state of Mississippi due to low numbers of historical records. This species is known to inhabit wood pile habitat in rivers, a habitat that has been under-sampled historically due to …

Geomorphic Assessment and Flow Modeling of Pearl Darter (Percina aurora) Habitat in the Pascagoula River Watershed
… One such species is the Pearl Darter, <em>Percina aurora</em>, a federally threatened species that only resides in the Pascagoula River watershed. Despite its status, habitat preference remains unclear. To fill this knowledge gap, I developed a novel approach to summarizing morphological …

Investigations of Phylogenetic Relationships of the Percidae (Actinopterygii: Perciformes) Using Comparative DNA Sequences
… monophyletic lineages of percid fishes, the Luciopercinae (Stizostedion, Zingel, and Romanichthys), the Percinae (Perca and Gymnocephalus), and the Etheostomatinae (Etheostoma, Percina, Ammocrypta, and Crystallaria). However, relationships among these three lineages are unresolved with this …

Multi-scale patterns of habitat use by Roanoke logperch (Percina rex) in Virginia rivers: a comparison among populations and life stages
The Roanoke logperch (Percina rex) is a federally endangered large darter that occurs only within the Roanoke and Chowan drainages of Virginia. This dissertation examines multi-scale habitat use patterns by logperch in three river systems in Virginia, including comparisons among rivers and life …

Habitat models for predicting the occurrence of blotchside logperch (Percina burtoni) and tangerine darters (P. aurantiaca) in the North Fork Holston River and Little River, Virginia
… characteristics) for blotchside logperch (<i>Percina burtoni</i>) and tangerine darter (<i>P. aurantiaca</i>) in the North Fork Holston River. Transferability of models, developed for both species in the North Fork Holston River, to Little River were tested by comparing the models' predictions …

Movement Patterns of the Kentucky Arrow Darter (Etheosotma spilotum), Frecklebelly Darter (Percina stictogaster), and Southern Redbelly Dace (Chrosomus erythrogaster) in Elisha Creek and Gilbert's Big Creek, Red Bird River, Kentucky.
… species under the Endangered Species Act. Percina stictogaster is acknowledged as a species of greatest conservation need in Kentucky by the Kentucky Department of Fish and Wildlife Resources. Over the duration of this study, a totlal of 182 fishes were PIT tagged and released in Elisha …

Egg Maturation and Fecundity in Etheostoma
… estimating fecundity in darters (Etheostoma and Percina) was discussed and a new definition of fecundity proposed. Estimates of fecundity in four species of Etheostoma was determined by multiplying the number of oocytes (≥0.3 mm) recruited per week times the number of weeks in the spawning …

Distributions, Assemblage Structure, and Habitat Associations of Fishes in Two Streams of the Red Bird River Watershed, Kentucky
… all seasons. Darter species (Etheostoma and Percina) selected riffles and runs while avoiding pools; whereas cyprinids selected pools while avoiding riffles and runs. Elisha Creek produced more total individuals; but overall the distributions, assemblage structures, and habitat associations …

The use of bioelectrical impedance analysis for estimating the body composition of various fish species
… Salvelinus fontinalis, and northern logperch Percina caprodes (r2 ≥ 0.71, p < 0.0001). I also determined that bluegill and redear regressions were not significantly different (P ≥ 0.10) suggesting they can be used interchangeably during future studies. Laboratory studies revealed that water …

Host Fish Assessment and Gravidity for the Mussel Elliptoideus sloatianus
… E. sloatianus glochidia to the juvenile stage. Percina nigrofasciata (blackbanded darter) transformed significantly more juveniles than the other 6 species, suggesting it is potentially a primary host. In addition, the period of gravidity for E. sloatianus was determined to be late-March to …

Using genetic tools to understand the population ecology of stream fishes
… southeastern United States: Roanoke logperch (Percina rex) of the greater Roanoke River basin and redline (Etheostoma rufilineatum) and greenside darters (E. blennioides) of the upper Tennessee River basin. I found that endangered P. rex persists in seven isolated populations. Within …

Nutritional condition and stress response of fishes along a gradient of habitat quality in the St. Lawrence River: physiological consequences of anthropogenic habitat degradation
… brown bullhead Ameiurus nebulosus, and logperch Percina caprodes had altered GC function as a result of anthropogenic stream degradation, whereas white sucker Catostomus commersonii and pumpkinseed Lepomis gibbosus did not. Together, my results show that different species residing in identical …

The Ecological Niche of Darters (Pisces:Percidae) Across Multiple Scales in the Ohio River Basin
… while weakly pelagic species, such as <i>Percina</i> darters, were associated with depth. <i>E. blennioides</i>, <i>E. rufilineatum</i> and <i>C. carolinae</i> showed significant expansion (p < 0.05) in their use of each percent substrate size in the Pigeon River relative to reference …

Factors Influencing Darter Dispersal Patterns in the Upper Roanoke River Watershed, Virginia
Effective delineation and management of stream fish populations requires a thorough knowledge of dispersal patterns, because these patterns affect a number of other demographic rates such as population growth, reproduction, survival, and gene flow. Previous studies of stream fish dispersal patterns …
