RESULTS Macroinvertebrates: selection of a biological index Sampling protocol For each protocol and team the IBMWP (for riffles and pools) and FBILL (only riffles) were calculated. The data, presented in Figure 2, indicates that there are no differences in water quality for both indices using both protocols. It can be seen that all the teams have arose the “Very good biological quality” for the FBILL and IBMWP indices. IBMWP FBILL 250 200 150 100 50 120 10 8 6 4 2 0 Protocol 1 Protocol 2 G1 G2 G3 G4 G1 G2 G3 G4 Figure 2. Values of IBMWP and FBILL for all sampling groups and both protocols. The IBMWP has been calculated using the community in the integrated sample (R+L) and the FBILL only in the lotic habitat (R). The discontinuous lines show the values of each biotic index and it can be considered a water quality of “Very good” (>100 in the IBMWP and between 8-10 in the FBILL) (G1, G2, G3 and G4=Groups 1, 2, 3 and 4). 41
<strong>Chapter</strong> 1 Macroinvertebrates: effect of the sampling protocol An analysis of the variance was performed to compare the number of families and the values of the IBMWP and IASPT, for both protocol and habitats, using each sampling team as replicates (n=4). According to the results, there are not significant differences between Protocol 1 and 2 in the IBMWP and IASPT indices (p=0.4884 and p=0.5924) (see Figure 3). Either, the total number of families found did not show differences between protocols (p=0.4832) or habitats (p(pools)=0.8351 and p(riffles)=0.7608).
