摘要: Benthic communities are widely used in the monitoring of effects marine pollution as organisms mostly sessile and integrate pollutants over time. Most benthic comprise a large number species because varying sensitivities it should be possible to identify subtle reflected changes community structure. The response index (BRI) is multivariate that measures abundance-weighted average tolerance occurring sample, comparable weighted approach gradient analysis. Quantitative application throughout southern California coastal shelf environment was undertaken conditions communities, with levels environmental disturbance defined by identified thresholds. values, at which key attributes were lost, established four levels. use BRI has been compared infaunal trophic (ITI), an extensively area.
