Fig. 4 in Fish assemblages in stream stretches occupied by cattail (Typhaceae, Angiospermae) stands in Southeast Brazil

Fig. 4. (a) Ordination resulting from Nonmetric Multidimensional Scaling Analysis (NMDS) with percent composition by number of feeding items from fishes of six stream stretches (S1-S6) in the dry and wet periods. (b, c, d) Contribution (the larger the circle, the greater the percent composition by number) of Ceratopogonidae larvae (b), Coleoptera larvae (c), and Collembola (d) to the fishes' diet. A stress of 0.08 corresponds to a good ordination with no real prospect of a misleading interpretation (Clarke & Warwick, 2001).
