Differential stability of spawning microhabitats of warmwater stream fishes
… streambed stability in spawning microhabitats of warmwater fishes in the upper Roanoke River, Virginia. Spawning microhabitats used by four reproductive guilds (egg-clusterers, mound-builders, egg-buriers, and pit-builders) were identified and ranges of 15 microhabitat variables used by each guild …

Developing an index of biotic integrity (IBI) for warmwater wadeable streams in Virginia
The index of biotic integrity (IBI) comprises several fish-assemblage attributes, called metrics, that reflect how a site differs from least-disturbed (by anthropogenic influences) conditions. Understanding how metrics at least-disturbed sites vary across landscape classes (e.g., physiographies, …

Aquatic Macroinvertebrate Production in Predominant Habitats of a Warmwater Stream: The James River, South Dakota
… instream features and habitat diversity in warmwater streams. Special consideration also should be given to the protection of streamside forests.

Healing the land : monitoring transformation and agricultural sustainability on a Western Cape land reform project
… reform opportunities in the Western Cape. The Warmwater farming Trust, a land reform project in the Western Cape premised on this model, formed the case study component of my research. Political ecology was adopted as the theoretical framework for linking structural underpinnings and the …

A study of lethality and toxic mechanisms of intermittent chlorination to freshwater fish
… plants are on streams with predominantly warmwater fish, it was important to determine the effects of the intermittent release of chlorine on a fish of this type. The toxicity of intermittent chlorination, and the possible interaction with temperature to a warmwater fish, bluegill (Lepomis …

The Importance of Thermal Habitat Quality for Pumpkinseed (Centrarchidae: Lepomis gibbosus) in Small and Constructed Coastal Embayments Along the Northwest Shoreline of Lake Ontario
… ha) are being constructed or modified to restore warmwater fish habitat. I describe how Lake Ontario (hereafter the Lake) alters the thermal regime of these small coastal embayments, how the altered thermal regimes affect growth and survival of age-0 warmwater fishes, and how the thermal habitat …

Spatiotemporal response of aquatic native and nonnative taxa to wildfire disturbance in a desert stream network
… and fishes in canyon habitats, a warmwater tributary, or in valley sites, respectively. The second objective was accomplished by measuring biomass changes of a warmwater native and nonnative community during 2010-2013 before and after consecutive, uncharacteristic wildfires. …

Behavioral avoidance by fish of residual chlorine in power plant discharges
… discharges may not adequately protect all warmwater fish. This study indicates that HOCl may greatly influence fish behavior and suggests that HOCl criteria be adopted for use in conjunction with current total residual chlorine criteria.

Identification of Ecosystem Stressors in Developing an Enhancement Plan for the Leading Creek Watershed, Meigs County, Ohio
… Leading Creek from attaining either the Warmwater Habitat (WWH) or the Excellent Warmwater Habitat (EWH) designation and to provide potential remediation techniques to address the identified stressors. Although natural processes have lead to partial recovery in Leading Creek from the …

The roles of predation, competition, and exploitation in the community dynamics of the New River in West Virginia
… exploitation in the food web of this large, warmwater stream. The fates of production of the harvested crayfish (Orconectes virilis, Orconectes sanbornii sanbornii, and Cambarus sciotensis), hellgrammite (Corydalus cornutus larvae), smallmouth bass (Micropterus dolomieui), rock bass …

Developing Habitat Suitability Criteria for Individual Species and Habitat Guilds in the Shenandoah River Basin
The diversity of fish species found in warmwater stream systems provides a perplexing challenge when selecting species for Instream Flow Incremental Methodology (IFIM) studies. An often-suggested approach has been to use habitat guilds to incorporate the diversity found in these systems. My goal is …

Fish Community Assembly in the Missouri River Basin
Warmwater fish communities of the Missouri River basin are poorly studied. I conducted a series of investigations intended to explain fish community structure and composition therein. I focused on relations between environmental characteristics and fish species because abiotic factors are …
