Rapid measurements of periphytic responses to nutrients using PAM fluorimetry
<p>Water quality monitoring has traditionally been done by measuring periphytic algal biomass that has grown on fertilized or unfertilized patches of habitat produced by nutrientdiffusing substrata (NDS). This method requires the destruction of the accumulated periphyton communities and thus does …

Effects of watershed land use on the benthic macroinvertebrate assemblages in ridge and valley streams in Chattanooga, Tennessee
… on the invertebrate community and over-all water quality. Characterizations of stream sites were made using indexes commonly used to qualitatively compare invertebrate assemblages including the total number of taxa (richness), and the number of families of insects belonging to the orders …

Integrating GIS with Benthic Metrics: Calibrating a Biotic Index to Effectively Discriminate Stream Impacts in Urban Areas of the Blackland Prairie Eco-Region
Rapid Bioassessment Protocols integrate a suite of community, population, and functional metrics, determined from the collection of benthic macroinvertebrates or fish, into a single assessment. This study was conducted in Dallas County Texas, an area located in the blackland prairie eco-region that …

Effect of riparian land use on the biotic integrity of fish assemblages in Black Creek, Chattanooga, Tennessee
… in Chattanooga, Tennessee. Most ofBlack Creek's watershed is forested (ca. 71% in 1991 ). However, increasing urban development, particularly along the riparian landscapes, could impact the stream's ecological health. I assessed fish assemblages (biotic integrity), water quality, instream …

Development, Validation, and Evaluation of a Continuous, Real-time, Bivalve Biomonitoring System
A biological monitoring tool to assess water quality using bivalve gape behavior was developed and demonstrated. The purpose of this work was to develop methodologies for screening water quality appropriate to the goals of the watershed paradigm. A model of bivalve gape behavior based on prediction …

Suspended Sediment Transport Dynamics and Sediment Yields in Relation to Watershed Characteristics, Upper Green River Basin, Kentucky
… and 151 fish species. The river also provides water for many of its surrounding counties. This research focuses on how suspended sediment loads, grain size, and sediment concentration during runoff events are related to watershed characteristics. The research characterized suspended sediment …

Microbiological evaluation of the Mhlathuze River in KwaZulu-Natal
… of the rural community that uses the river water directly for domestic use without treatment. The microbiological, physical and chemical analysis of the Mhiathuze River was investigated over a twenty-one months period. Five water samples were collected along the Mhiathuze River and analysed …
