A Vegetation-Based Index of Biotic Integrity for Wetlands of Kentucky
… States, prompting efforts to assess the status of remaining wetlands and regulate their development. The Clean Water Act and the policy of “No Net Loss” have resulted in a system of permitting and mitigation for impacts to wetlands. Professional judgments of wetland quality are inherent in …

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, …

The Effect of Habitat on the Index of Biotic Integrity (IBI) in Bull Creek, Southwest Missouri
… was conducted in the Bull Creek drainage basin of the Missouri Ozarks between 1 June and 1 September, 2001. The goals of this study were to characterize the fish assemblages, evaluate specific habitat variables, and measure the index of biotic integrity (IBI), using fish assemblages as response …

A Comparison of the Index of Biotic Integrity by Habitat Type in Swan Creek, Southwest Missouri
A multimetric Index of Biotic Integrity (IBI) based on fish communities was used to score Missouri streams as an assessment of stream health. During summer 2002 we sampled Swan Creek, a 5th order stream in Southwest Missouri, which flows into the White River system. We sampled 19 sites, collecting …

Fish Community Structure and Water Quality Assessment (Index of Biotic Integrity) of the San Marcos River, Texas
… from point and nonpoint sources using the Index of Biotic Integrity (181). The stable water temperature, flow and clarity found in the headwaters of the San Marcos River has allowed the development of a refugia for endemic and introduced aquatic plants and animals. Over the entire length of …

A Comparison of Water Quality Analyses and the Index of Biotic Integrity in Bull Creek, Southwest Missouri
There is growing awareness of the relationship between environmental and human health. With this awareness comes the understanding that steps must be taken to balance the needs of humans with the overall health of the environment. Although water chemistry has played a major role in assessing …

Using the Index of Biotic Integrity of Fish Communities to Evaluate Habitat Quality in Middle Chattahoochee River Tributaries
… and upper Coastal Plain physiographic regions of the middle Chattahoochee River drainage basin between August 1998 and September 2000. Sampling was conducted by Columbus State University (CSU) under contract to Columbus Water Works for the purpose of obtaining biological measurements of …

The Development and Evaluation of an Index of Biotic Integrity for Small Lakes in Western and Central New York
The ecological "health" of aquatic ecosystems is important to scientists, resource managers, and the general public. In order to properly protect or restore the integrity of an aquatic system we must first accurately assess its present condition. The Index of Biotic Integrity (IBI) is a relatively …

Temporal Change in Fish Communities and Modification of the Index of Biotic Integrity for the James River of the Dakotas
… My first objective was to examine persistence of the James River fish community over an 11 and 25-year period. My second objective was to assess the relative abundance of fish among four major habitats (snag, low head dam. rocky bottom. and simple) following a wet I dry hydrologic cycle. …

Chironomidae Contributions to the Macroinvertebrate Assemblage, Index of Biotic Integrity and Relationships to Water Quality Impairment for Eastern South Dakota Streams
… in natural resource condition. Contribution of Chironomidae to macroinvertebrate assemblage structure has not been explored extensively from wadeable perennial streams of the Northern Glaciated Plains (NGP). Moreover, no effort has been attempted to develop a multimetric index of biotic …

Effects of land use on biotic integrity in ridge and valley streams in the Chattanooga Metropolitan Area, Tennessee-Georgia
… were studied from April-August, 1999, as part of the Urban Streams Project. All sites are in the Ridge and Valley ecoregion and are part of the Nickajack Reservoir watershed in the Tennessee River system. Study sites were characterized in terms of water quality, habitat, and fish assemblages. …

A Biological Assessment of the Fish and Benthic Macroinvertebrates From Two Urban Streams in Springfield, Missouri
This study assessed the health of two biotic communities in Jordan and Galloway Creeks in Springfield, Missouri. Fish and benthic macroinvertabrate samples were collected from each stream using the U.S. Environmental Protection Agency’s Rapid Bioassesment Protocols for Use in Wadeable Streams and …

Effects of Trout Introduction on Community Assemblage and Behavior of Native Fish in the Missouri Ozarks
… few studies to date investigating the effects of trout introduction on native fish. Fish communities were sampled in the fall of 2013 to assess potential impacts of trout introduction on community assemblage and behavior of native fish. An index of biotic integrity (IBI) was used to compare …

Association of Lead and Zinc on Fish Diversity in the Spring River Basin, Missouri
The main objective of this thesis project was to determine if fish diversity and community integrity were associated with zinc and lead contamination in the Spring River Basin, southwest Missouri. Sampling sites were located in the Tri-State mining district where zinc and lead were once heavily …

Relations among biochemical, individual, and community indicators of stress in fish: stream degradation in the Clinch River drainage
… The data were collected in parallel with a study of the index of biotic integrity (IBI) on fish communities also in the Clinch River drainage. Sites selected for this study were identical to those used for IBI. Data obtained from fish sampled at relatively pristine sites (i.e., high IBI) were used …

Influences of watershed urban development on habitat heterogeneity and native fish diversity in a ridge and valley stream in Southeastern Tennessee
The present study examined relationships of landscape features with instream environmental conditions and fish assemblage attributes in a third-order Ridge and Valley stream in the Chattanooga, Tennessee area. Stream water quality, habitat, and fish assemblages were sampled in May-June 2005 at …

Fish Community Structure and Associated Habitat in the James River, Southwest Missouri
The focus of this study was to determine the relationship between fish populations and habitat characteristics in the mainstem of the James River in Southwest Missouri. Establishing a history of the existing fish and habitat populations is necessary to formulate a robust Index of Biotic Integrity …

Benthic Community Analysis of Hog Island Bay, Virginia
… benthic infaunal macroinvertebrate communities of Hog Island Bay of the Virginia Eastern Shore were quantitatively sampled at 30 locations on August 31 and September 1, 1995. The primary objectives of this study were: (1) to characterize the subtidal macroinfaunal benthic communities of Hog …
