Fig. 1. Nonmetric-multidimensional scaling (NMS) plot of community fatty acid profiles from soils with three different levels of pollution (nonpolluted, NP; polluted and reclaimed, PR; and polluted, P) extracted by phospholipid-linked fatty acid (PLFA) or ester-linked fatty acid (ELFA) methods. The proportion of variance explained by each axis is based in the correlation between distance in the reduced NMS space and distance in the original space and is reported after each axis heading.
