Fig. 2. Ordination of the co-structure between (a) fish assemblages (arrows) and stream sites (squares) and (b) fish species and environmental variables resulting from the co-inertia analysis. Only species that most contributes to each axis are displayed. Black and white squares represent stream sites sampled in the wet and dry season, respectively. Codes correspond to names listed in Tables 1 and 2. Small boxes indicate the graphic scale.
