Relationship between depth, sediment, latitude, and the structure of benthic infaunal assemblages on the mainland shelf of southern California
Mary Bergen,Stephen B. Weisberg,Robert W. Smith,Donald B. Cadien,Ann Dalkey,David E. Montagne,Janet K. Stull,Ronald G. Velarde,J. Ananda Ranasinghe +8 more
TL;DR: Benthic abundance and diversity were greatest in the mid-depth assemblage, conforming to predictions for benthic assemblages in regions of upwelling.

Assessing coastal benthic macrofauna community condition using best professional judgement--developing consensus across North America and Europe.
Heliana Teixeira,Ángel Borja,Stephen B. Weisberg,J. Ananda Ranasinghe,Donald B. Cadien,Daniel M. Dauer,Jean-Claude Dauvin,Steven Degraer,Robert J. Diaz,Antoine Grémare,Ioannis Karakassis,Roberto J. Llansó,Lawrence L. Lovell,João Carlos Marques,David E. Montagne,Anna Occhipinti-Ambrogi,Rutger Rosenberg,Rafael Sardá,Linda C. Schaffner,Ronald G. Velarde +19 more
TL;DR: The absence of regional bias suggests that expert judgment is a viable means for establishing a uniform scale to calibrate indices consistently across geographic regions.

The level of agreement among experts applying best professional judgment to assess the condition of benthic infaunal communities
Stephen B. Weisberg,Bruce Thompson,J. Ananda Ranasinghe,David E. Montagne,Donald B. Cadien,Daniel M. Dauer,Douglas R. Diener,John S. Oliver,Donald J. Reish,Ronald G. Velarde,Jack Q. Word +10 more
TL;DR: This paper examined the repeatability of such assessments by providing species-abundance data from 35 sites to 9 independent benthic experts who ranked the sites from best to worst condition, with an average correlation coefficient of 0.91.

Calibration and evaluation of five indicators of benthic community condition in two California bay and estuary habitats.
J. Ananda Ranasinghe,Stephen B. Weisberg,Robert W. Smith,David E. Montagne,Bruce Thompson,James M. Oakden,David D. Huff,Donald B. Cadien,Ronald G. Velarde,Kerry J. Ritter +9 more
TL;DR: In this article, the BRI, BQI, Relative Benthic Index (RBI), River Invertebrate Prediction and Classification System (RIVPACS), and the Index of Biotic Integrity (IBI) were compared.

The prevalence of non-indigenous species in southern California embayments and their effects on benthic macroinvertebrate communities
J. Ananda Ranasinghe,Tim K. Mikel,Ronald G. Velarde,Stephen B. Weisberg,David E. Montagne,Donald B. Cadien,Ann Dalkey +6 more
TL;DR: The prevalence of non-indigenous species (NIS) in southern California embayments was assessed from 123 Van Veen grab samples collected during the summer of 1998 and NIS abundance was positively correlated with the abundance and richness of other species.
