Environmental data for each site were used in redundancy analysis (RDA). Sample nomenclature is as follows: region-substrate-deployment reference. Sites are: Contr, control; GoC, Gulf of Cadiz; EM, eastern Mediterranean; MAR, mid-Atlantic Ridge; HMMV, Haakon Mosby mud volcano. Substrate: alfalfa (A) or wood (W). Deployment reference from I to V.
