Increased scale enabled detection of a greater number of species per unit area but reduced the percentage of species richness variation explained by pasture position and management.

We found that the presence of ILHC decreased the number of species for all tree groups, being this variable the major driver of richness variation across forest remnants.

In conclusion, the Chironomidae community structure presented an increase in larva density during the experimental period associated with changes in taxon composition; however, the total taxonomic richness variation was low and functional richness did not vary.
