摘要: The results of manipulating the input data to AMBI are explored using various transformations numerical species abundance (NAMBI), biomass (BAMBI) and production (PAMBI) from a variety stations on NE Atlantic shelf at which pollution/disturbance status is known. There close agreement between proportions in five ecological groups phylum level meta-analysis axis increasing environmental impact. All measures provide better monotonic relationship with impact than do traditional diversity measures, show higher intermediate levels disturbance. A marginally achieved by moderate (square root) transformation data. 'Production' (an appropriate combination information) only marginal improvement data, but ecologically functionally much more relevant. Severe culminating presence/absence, degrades axis, if simple lists available then these may still be useable making an assessment.
