WebDistance base redundancy analysis (db-RDA) is very similar to standard redundancy analysis (RDA) however, db-RDA is capable of performing redundancy analysis with any type of distance matrix. This is especially advantages with species datasets which typically utilize the Bray-Curtis distance matrix to compensate for rare species counts.
