Thank you very much Roman. I will check for papers you suggested me  
for sure. Sometimes, maybe especially for me that I am not deep inside  
statistics yet, is simple to get outputs (with R) but is extremely  
difficult to understand what they mean and comunicate about the  
data... i.g. In a NMDS ordination how to comment distances of species  
in relation to sample points?
Thank you all for patience,

G.
