The figures <strong>in</strong> the symbols are replication numbers, correpond<strong>in</strong>g tothat <strong>in</strong> Fig. 1. The solid and broken arrows <strong>in</strong>dicate significant environmental gradients at p=0.05and 0.10, respectively. The diagrams are based on: a, antibiotic resistance MPN method; b, diskdiffusion method; c, 0.2 AWCD (Biolog); d, 0.6 AWCD; e, 1.0 AWCD; f, 1.4 AWCD.
