Fig. 3 in Fish assemblages in stream stretches occupied by cattail (Typhaceae, Angiospermae) stands in Southeast Brazil

Fig. 3. Representation the two first axis of the Canonical Correspondence Analysis, showing the sampled stretches (labelled S1-S6) in the dry and wet periods (circles), species (triangles), and environmental descriptors (arrows). The eigenvalue of axis 1 and axis 2 are 0.26 and 0.16, respectively, displaying 38% of the total inertia (= weighted variance) in the abundances and 68.8% of the variance in the weighted averages and class total of species with respect to the environmental variables. Monte Carlo significance test (4.999 permutations) under the full model option indicate that canonical axes are marginally significant ("F-ratio" = 1.509, P-value = 0.09). To species codes see Table 3.
