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
… and measure the index of biotic integrity (IBI), using fish assemblages as response to habitat variables. Physical habitat variables included mean wetted width, mean thalweg depth, mean canopy density, kilometers to the confluence of Bull Creek with Lake Taneycomo, temperature, substrate …

PEAK FOR IBI: EXAMINATION OF THE UTILITY OF THE PEAK RELATIONAL TRAINING SYSTEM FOR INTENSIVE BEHAVIORAL INTERVENTION
… (ASD), within Intensive Behavioral Intervention (IBI). Experiment 1 examined the relationship between scores on the commonly used Vineland Adaptive Behavior Scales Second Edition (VABS-II) (Sparrow, Cicchetto, & Balla, 2005) and scores on the PEAK Direct Training (PEAK-DT) (Dixon, 2014a) and PEAK …

Using the Index of Biotic Integrity of Fish Communities to Evaluate Habitat Quality in Middle Chattahoochee River Tributaries
… were the establishment of a data baseline of IBI scores for this ecoregion and to ascertain if there was a correlation between the IBI score and human influence. The thesis to be tested is: 'Fish community IBI scores of different watersheds within the Middle Chattahoochee drainage basin will …

Relations among biochemical, individual, and community indicators of stress in fish: stream degradation in the Clinch River drainage
… 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 as references to be compared with …

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 …

SCIENCE TEACHERS’ UNDERSTANDING AND PRACTICE OF INQUIRY-BASED INSTRUCTION IN UGANDA
… teach science through Inquiry-Based Instruction (IBI) to motivate the students to learn science. However, there have been no empirical studies done to establish the factors that influence science teachers’ understanding and practice of IBI in Uganda. Most of the published research on IBI has been …

Biotic Integrity in the Northwestern Great Plains and Mechanisms Regulating Stream Condition in South Dakota
… easy to quantify. The Index of Biotic Integrity (IBI) is a unique method of assessing the aquatic health of an ecosystem. Beginning in 2010 the South Dakota Department of Environment and Natural Resources (SD DENR) began implementing biological monitoring on wadeable streams by developing an IBI …

Chironomidae Contributions to the Macroinvertebrate Assemblage, Index of Biotic Integrity and Relationships to Water Quality Impairment for Eastern South Dakota Streams
… develop a multimetric index of biotic integrity (IBI) using Chironomidae larvae. The objectives of this research were to (1) assess the contribution of Chironomidae assemblage structure to the total macroinvertebrate assemblage, (2) develop an IBI and validate the index against streams of known …

Physical and Biological Impacts of Gravel Mining on Three Southwest Missouri Streams
… assemblages using the Index of Biotic Integrity (IBI). The IBI uses 12 fish community metrics, which I compared among stream reaches. I also compiled total IBI scores for each stream reach sampled. I found higher densities of smallmouth bass (Micropterus dolomieu) at the sites upstream of gravel …

Quantification of the Effectiveness of Agricultural Riparian Buffers to Protect Stream Health in Maryland's Coastal Plain and Piedmont Regions
… A set of landscape characteristics describing the agricultural riparian landscape was developed, from which a classification system for agricultural riparian landscapes was developed. The Agricultural Riparian Classification System can identify a subset of sites for targeted research. …

Inquiry-based instruction: The role of mindset for students with mathematics difficulties
The effectiveness of inquiry-based instruction (IBI) is well documented, however its use with students with mathematics difficulties (MD) has been limited, since it is often thought such methods are unsuitable for low attaining students. However, this belief is not entirely evidence based, and …

Development Of An Avian Index Of Biological Integrity For Kentucky Wetlands
… an avian index of biological integrity (IBI) for wetlands of Kentucky as an intensive assessment method to supplement an existing rapid assessment method used in regulatory programs. Birds are useful indicators because they are sensitive to environmental changes, abundant in various …

Association of Lead and Zinc on Fish Diversity in the Spring River Basin, Missouri
… used to calculate an index of biotic integrity (IBI) using eleven metrics. Upon analysis of the IBI index, level of metals contamination, and habitat quality, several trends appeared. There was a direct correlation between zinc concentrations and lead contamination. There was no significant …

Development and Application of Vegetation-Based Biomonitoring Criteria for Floodplain Wetlands
… of a plant-based index of biotic integrity (P-IBI). Box plots and stepwise discriminant function analysis were used to identify the metric associations that had the strongest discriminatory power for grouping reference and impaired wetlands. No plant metrics were found to accurately classify …

Effect of riparian land use on the biotic integrity of fish assemblages in Black Creek, Chattanooga, Tennessee
… and 9,178 fish. Index ofbiotic integrity (IBI) scores ranged from 30 to 42, corresponding to IBI ratings of "poor" to "fair," respectively, at the individual sites. The IBI score was negatively correlated with sediment depth in the stream (r = -0.727, P = 0.041) and the percentage of urban …
