Figure 4

Plots of the Fuzzy Correspondence Analysis showing the distribution of the different categories of each biological trait (Figure 4A to J), these same categories are listed in Table1. Figure 4K shows the distribution of the stream-sites clustered per watershed (1 for AOW and 2 for CAIW). In Figures 4A to J, the size of the black bold circles representing the traits’ categories indicates the weight of these categories in the analysis. Plot A is for maximal size, plot B for dispersal (Aq-P for aquatic passive dispersal, Aq-A for aquatic active dispersal, Aer-P for aerial passive dispersal, Aer-A for aerial active dispersal), plot C for life cycle duration, plot D for potential number of life cycles per year, plot E for feeding habits (Dep and Fil are for Deposit- and Filter-feeder, respectively), plot F for substrate preferendum (Mac and Mic are for Macrophyte and Microphyte, respectively), plot G for current velocity, plot H for trophic status (Oligo, Meso and Eutr are for Oligotrophic, Mesotrophic and Eutrophic, respectively), plot I for temperature preferendum, and plot J for saprobity (Xeno, Oligo, α-meso, β-meso, Poly are for Xenosaprobic, Oligosaprobic, α- mesosaprobic, β-mesosaprobic and Ploysaprobic, respectively).
