A total of 9,982 specimens were captured, belonging to the families Scarabaeidae and Trogidae, and representing 21 genera and 50 species. The genera Ataenius Harold, Onthophagus Latreille and Aphodius Illiger represented 48% of the species of Scarabaeidae. Species richness was found to decrease with increasing altitude; there were 36 species at 1000 m asl, 27 species between 1200 and 1300 m asl, and 26 species at 1400 m asl. Abundance along the altitudinal gradient follows a pattern of few abundant species and many species with few specimens. Beetle activity is related to precipitation. In the nine communities studied, species richness was observed to increase when precipitation was greater than 100 mm at the beginning of the rainy season. On the landscape scale, there were 44 species during the rainy season, 22 during the windy nortes season, and 24 during the dry season. In terms of trophic guild, 40% of the beetles captured were saprophagous that feed on decomposing organic material from plants and 60% were saprophagous that feed on decomposing organic material from animals (30% necrophagous, 26% coprophagous, 4% telio-necrophagous). 10abeetle10acoprophagous10anecrophagous10asaprophagous10atrophic guild1 aDeLoya, Cuauhtemoc1 aParra-Tabla, Victor1 aDelfin-Gonzalez, Hugo  uhttps://scarabnet.myspecies.info/fauna-de-coleopteros-scarabaeidae-laparosticti-y-trogidae-coleoptera-scarabaeoidea-asociados-al-bosq02259nas a2200217   4500008004100000245010600041210006900147300001000216490000700226520149700233653001901730653001701749653002401766653001801790653001701808653001301825100002701838700002601865700002401891856012601915       2007                        eng d00aCopro-necrophagous beetle (Coleoptera: Scarabaeidae) diversity in an agroecosystem in Yucatan, Mexico0 aCopronecrophagous beetle Coleoptera Scarabaeidae diversity in an  a83-990 v553 aScarabaeinae 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.10aagroecosystems10abiodiversity10aBrosimum alicastrum10afragmentation10aScarabaeinae10aYucatan.1 aNovelo, Enrique, Reyes1 aDelfin-Gonzalez, Hugo1 aMoron, Miguel-Angel  uhttps://scarabnet.myspecies.info/copro-necrophagous-beetle-coleoptera-scarabaeidae-diversity-agroecosystem-yucatan-mexico
