Fig. 4From: Subtidal macrozoobenthos communities from northern Chile during and post El Niño 1997–1998Observed (solid symbols) and expected (empty symbols) C-scores (±95% confidence intervals) calculated by including species from all feeding groups together (All species) and separately for each feeding group during (a) and after (b) EN 1997–1998. If observed C-scores level off outside upper confidence interval limit of their respective C-score expected by chance, the observed value is significantly higher that the expected one (i.e., P (observed > expected) < 0.05). Feeding groups are the same as in Table 2 Back to article page
