Fig. 2 in Influence of environmental parameters on fish assemblage of a Neotropical river with a flood pulse regime, Central Brazil
Fig. 2. Ordination of the co-structure resulting from the co-inertia analysis between the fish assemblages and quantitative (a) and qualitative (b) environmental parameters (square arrow edge = stretch; circle = fish assemblage). Numbers represent the stretch sampled at low (L) or high (H) waters. Letter codes correspond to the main fish species that contributed to the costructure and are listed in Table 1. CD = channel depth; CW = channel width; DO = dissolved oxygen; ST = Secchi transparency; RS/S/L/R = river substrate/sand/leaves/roots; RVC/H = river vegetation cover/high; RVC/A/H = river vegetation cover absent/ high; RS/S/L = river substrate/sand/leaves; RVC/F = river vegetation cover/flooded. Boxes indicate scales.

Fig. 2. Relative biomass (2a) and relative catch (2b) of the main species of the ITAIPU-2 model, with increasing of fishing effort. Fishing effort = 1 is equivalent to that registered in 1998. This value was multiplied by 2, 3 and 4, in order to get other fisheries scenarios. Simulations made in Ecopath with Ecosim (Subroutine: Run Ecossim, module: Results).
