	abstract = {Scarabaeinae are sensitive to structural habitat changes caused by disturbance. We compared coprone- crophagous beetle (Scarabaeinae) community structure in three differently managed zones within an agroeco- system of the northern Yucatan Peninsula, Mexico. We placed dung and carrion traps once a month from June 2004 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 highest in the Brosimum alicastrum plantation. The pasture had the lowest species diversity and richness, but exhibited the highest abundance of Scarabaeinae in the dry season. The two zones with extensive tree cover were the most diverse. 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 the dry season, while abundances dropped in the other, unirrigated zones; and the possibility that the Scarabaeinae living in neotropical forests are opportunistic saprophages and have specialized habits for resources other than dung. The B. alicastrum plantation is beneficial to the entire ranch production system because it functions as a dispersion and development area for stenotopic species limited to tree cover.},

	abstract = {A study of the Melolonthidae and Passalidae beetle fauna of Conkal and Tzucacab, Yucatan, Mexico is presented. Data from 6,378 specimens were obtained during 2001-2002 with 74 days of collecting effort in tropical deciduous forest and secondary vegetation, located between 9-70 m of altitude. Forty nine species of the genera Phyllophaga, Diplotaxis, Anomala, Chasmodia, Macraspis, Plesiorutela, Pelidnota, Cyclocephala, Ligyrus, Strategus, Coelosis, Phileurus, Gymnetis, Cotinis, Hoplopyga, Balsameda, Amithao, Euphoria, Trigonopeltastes, Passalus, Heliscus and Verres, are recorded. Species were more abundant in April, May and June. Most of them were from Conkal, but higher species richness was found in Tzucacab. Eighteen species are reported for the first time from Yucatan State. Hoplopyga ocellata G. \& P. and Euphoria subguttata Burmeister are confirmed as part of the Mexican fauna. A key to the 49 species, as well as comparative data between scarab beetle fauna of Tzucacab, Conkal and other tropical localities of Mexico, are included. Some biogeographically, agricultural and conservational aspects of these fauna are briefly discussed.},
