Abstract
Biodiversity indicator beetles were evaluated to establish diversity and abundance at four localities, including disturbed and conserved environments, to contribute to a conservation proposal. Species of coprophagous biodiversity indicator beetles were collected during four field trips to four localities, indicating a decreasing disturbance gradient in tropical deciduous forests from north to south, of the Atoyac-Tehuitzingo sub-basin, between 18.67° and 17.97°N latitude. Species richness indicated an increasing (non-significant) number (S = 3 versus 10) relative to the disturbance pattern; diversity showed an increasing (significant) pattern from north to south (H′ = 0.74 versus 1.17). The effective number of species was 1.5 times greater at Tulcingo (south) than at San Mateo (north), consistent with the diversity pattern. The richness of Scarabaeinae beetle species as indicators of diverse environments could be sensitive to disturbance of vegetation in the Basin; however, more work is needed to overrule the effect of other environmental variables.
