An estuarine benthic index of biotic integrity (B-IBI) for Chesapeake Bay
Stephen B. Weisberg,J. Ananda Ranasinghe,Daniel M. Dauer,Linda C. Schaffner,Robert J. Diaz,Jeffrey B. Frithsen +5 more
TL;DR: A multimetric benthic index of biotic integrity (B-IBI) was developed using data from five Chesapeake Bay sampling programs conducted between 1972 and 1991 as discussed by the authors, which was calculated by scoring each selected metric as 5, 3, or 1 depending on whether its value at a site approximated, deviated slightly from, or deviated greatly from conditions at the best reference sites.

TL;DR: The blueprint expands and refines the use of high-throughput and computational modeling approaches to transform the components in chemical risk assessment, while systematically addressing key challenges that have hindered progress.
Chesapeake Bay benthic community restoration goals
Journal ArticleDOI
Application of two indices of benthic community condition in Chesapeake Bay
J. Ananda Ranasinghe,Jeffrey B. Frithsen,Frederick W. Kutz,John F. Paul,David E. Russell,Richard A. Batiuk,Jeffrey L. Hyland,John Scott,Daniel M. Dauer +8 more
TL;DR: In this article, the Chesapeake Bay Benthic Index of Biotic Integrity (B-IBI) and the Environmental Monitoring and Assessment Program (EMAP-VP BI) were compared.
Book ChapterDOI
Benthic Communities as Indicators of Ecosystem Condition
TL;DR: The bottom-dwelling (benthic) communities are major secondary consumers in coastal and estuarine ecosystems, frequently representing one of the largest living pools of organic carbon as discussed by the authors.
