Figure 5. Relationships between environmental variables and the behavioral diversity metrics (divergence, evenness and richness) in the Zygoptera. The continuous lines represent positive relationships and the dashed lines, negative ones. The darker the arrow, the higher the beta values. The values presented refer to the beta values of multiple regressions. V1 habitat integrity index, V2 electrical conductivity, V9 mean small tree canopy cover, V12 substrate D50, V14 non-agricultural land use, V15 large woody debris in channel, V19 volume of
