Detection of Stress on Macrozoobenthos: Evaluation of Some Methods in a Coastal Mediterranean Lagoon

摘要

The effects of taxonomic aggregation, the ABC-technique ad meta-analysis approaches were tested along a known stress gradient in the Orbetello lagoon, a Mediterranean coastal brackish basin. Multivariate analyses of taxonomic aggregated data detected differences among the three sampled areas except biomass phylum data analyses which showed a marked loss of information. ABC curves did not succeed in differentiating stress levels at various sites of The Orbetello lagoon.
