A new multivariate mapping method for studying species assemblages and their habitats: example using bottom trawl surveys in the Bay of Biscay (France)
S Souissi, F Ibanez, RB Hamadou, J Boucher… - Sarsia, 2001 - Taylor & Francis
This new numerical approach proposes a solution to a fundamental and difficult question in
ecology, consisting of the correct geographical representation of multidimensional
structures. Firstly, transformation was applied to the original matrix (n sites xq variables) in
order to satisfy the condition of multinormality. Then, a hierarchical cluster analysis was used
and each hierarchical level was studied and characterised by a certain probability level. For
each cut off level an algorithm based on the computation of the Bayesian probabilities …
