Abstract

With this note we contribute to the discussion on the appropriate level of taxonomic resolution required in benthic monitoring studies. In a set of multivariate analyses using data from different taxonomic levels and various data transformations we show that similar results are obtained on the levels of species to families, almost irrespective of the transformation used. For taxonomic levels above that of orders, transformation results in different plots and especially presence/absence transformation reduces the discrimination of sites. We recommend guiding the choice of transformation by biological considerations and adjusting the taxonomic sufficiency to the objective of each study.
