Best (a) and poorest (b) ecological group assignment of species to obtain AMBI-1 and AMBI-2. AMBI values are superimposed in colors on each macrofauna replicate obtained in Caucahue Channel as represented by nMDS. The nMDS for abundance was obtained through the Bray-Curtis index and fourth root transformed data. For the environment factor (ENV), circles represent mussel farms (MYT), squares represent salmon farms (SAL) and triangles represent reference sites (REF). The color indicates the level of disturbance according to the AMBI: undisturbed (blue), slightly disturbed (green) and moderately disturbed (yellow)
