•What does the result show (artefact or biology)?
•Do we have to much or to little information?
•Methods that compare?
•Do we enter new methodological arenas?
•Would it be possible to test explanation factors?

Multivariate analyses will include:
(1)Elimination of species from fish and benthos dataset that do not contribute to results of multivariate analysis (using Greenacre’s method) for both abundance (A) and biomass data (B)(2)Procrustes analysis relating CCA models results for fish and benthos (A and B)(3)Multivariate analysis of benthos-fish relationships using ter Braak's co-correspondence analysis (a special case of co-inertia analysis, looks at the relationship between two sets of abundance or biomass data) (ter Braak and Schaffers 2004).
