A Multimetric Benthic Index for Georgia's Wadeable Streams
<p>Using an ecoregional approach, multimetric indices were developed to describe stream condition in each geographically distinct region of Georgia. Collected from predetermined reference and impaired condition streams, macroinvertebrate data were used to develop multimetric indices. Multimetric …

Benthic Community Analysis of Hog Island Bay, Virginia
<p>The 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 …

Up an Urban Creek: The Role of Development Patterns in Stream Health
… managed by local planners. Available data for an index of macroinvertebrate communities, the Benthic Index of Biotic Integrity (BIBI), were used to assess stream health in twenty-two moderately-urbanized drainage basins (13 to 15 percent impervious area) in the Puget Sound lowlands. Land cover …

Novel approaches in macroinvertebrate biomonitoring
The increasing popularity of benthic macroinvertebrate use for biological monitoring and assessment of lotic systems calls for new applications for regions with a lesser known fauna and an overall better understanding of how community measures are influenced by seasonal variability. Two separate …

Evaluating the impacts of urbanization and stormwater management practices on stream response
… (EPT) richness, EPT percent richness, and a benthic index of biotic integrity (B-IBI) for the eight North Carolina Piedmont watersheds were found to be linearly related to the T0.5 hydrologic metric computed for 1-, 2-, 5-, 10-, and 20-year time periods. Qualitative multihabitat EPT richness …
