I'm currently working with macrobenthic communities in Admiralty Bay (King George Island ~ South Shetlands, Antarctic Peninsula) using a functional grouping approach to elucidate their assemblages.
Some preliminary research in one of its inlets (Mackellar Inlet) indicates that the ocean currents are an important variable that strongly influences over the coupling of the sampling stations. In order to run a multivariate analysis, I would like to incorporate these values into the analysis. Is there any special treatment that I have to do? Any further suggestion or recommendation?
I appreciate your response.
Unless you have already done so undertake an ordination of your benthic community data. Then examine the importance of your current data by fitting it to the the ordination as a vector. This can be done in R using the Vegan package, envfit procedure.

Thank you both for your answers. They will be very helpful. I'll dare to say that Envfit (R) and the Bioenv (PRIMER) are resemblant, is that right?
Aldo, is there any portal where I can get Canoco for free, or download it? If not, I'll ask my colleagues. Thanks again.
