Knowledge of the composition of natural communities and their responses to anthropogenic alterations is essential for determining the conservation status of a given system and prioritizing management actions. Anthropogenic impacts could cause a reduction in biodiversity not only due to habitat loss, but also due the loss of habitat heterogeneity across given landscape, especially in systems characterized by a mosaic of different elements (e.g. the Cerrado vegetation in central Brazil). Here we evaluate leaf beetle Coleoptera/Chrysomelidae) as bioindicators in a system whith varying intensities of human impacts and different phyto-physionomies (from open field to forests). We collected 1117 leaf beetle belonging to 245 species, of which 12 species and 5 genus were considered possible bioindicators based on IndVal measure. Higher species richness was observed in forests and regenerating fields, and habitats with lower species richness included pastures, mines and veredas. Only the Eucalyptus areas had a high abundance of Chrysomelidae, followed by forests and the other habitats, which were not significantly different from each other. Natural fields, regenerating fields, natural cerrados and forest had higher values of β-diversity. In general...
