We compared copronecrophagousbeetle (Scarabaeinae) community structure in three differently managed zones within an agroecosystemof the northern Yucatan Peninsula, Mexico. We placed dung and carrion traps once a month from June2004 through May 2005. The beetle community included 17 species from the genera Canthon, Canthidium,Deltochilum, Pseudocanthon, Malagoniella, Onthophagus, Phanaeus, Copris, Uroxys, Sisyphus and Ateuchus.The secondary vegetation had a higher beetle diversity than the other two zones. Species richness was highestin the Brosimum alicastrum plantation. The pasture had the lowest species diversity and richness, but exhibitedthe highest abundance of Scarabaeinae in the dry season. The two zones with extensive tree cover were the mostdiverse. Roller beetles were dominant over burrower species and small-sized species outnumbered large species.Our data show two important issues: beetle species in the pasture extended their activity to the beginning of thedry season, while abundances dropped in the other, unirrigated zones; and the possibility that the Scarabaeinaeliving in neotropical forests are opportunistic saprophages and have specialized habits for resources other thandung. The B. alicastrum plantation is beneficial to the entire ranch production system because it functions asa dispersion and development area for stenotopic species limited to tree cover. Rev. Biol.
