Number of taxa, accumulate IBMWP and IASPT for each hundred of individuals and for each working team. The average values and the standard deviation of the number of taxa, IBMWP and IASPT indices for all teams and habitats are presented in Figure 6. It can be observed a sharp increase of the average values of each variable between the 100 and 200 individuals, although standard deviations are quite high. No significant differences were found in any case between the fractions of number of individuals counted (p=0.6912 for the number of families; p=0.7293 for the IBMWP and p=0.9788 for the IASPT). Consequently, a count of 100 individuals would be enough to get an optimum number of individuals, a IBMWP and IASPT indexes, respectively, although the high standard deviation present between groups. 45 G1 G2 G3 G4

Mean values and standard deviation of the number of taxa, IBMWP and IASPT related with the fraction of the sample checked by all the sampling groups. In Figure 7 differences between both habitats are shown. As in the other cases, it can be observed an asymptotic increasing of the number of taxa for each fraction of counted individuals and for both habitats. The analysis of variance performed to compare both habitats indicated significant differences between pools and riffles (p
