Copro-necrophagous beetle (Coleoptera: Scarabaeidae) diversity in an agroecosystem in Yucatan, Mexico
Scarabaeinae are sensitive to structural habitat changes caused by disturbance. We compared copronecrophagous beetle (Scarabaeinae) community structure in three differently managed zones within an agroecosystem of the northern Yucatan Peninsula, Mexico.

| description | Scarabaeinae are sensitive to structural habitat changes caused by disturbance. We compared copronecrophagous beetle (Scarabaeinae) community structure in three differently managed zones within an agroecosystem 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. Rev. Biol. Trop. 55 (1): 83-99. Epub 2007 March. 31.<br>Este estudio describe y compara la estructura de la comunidad de escarabajos copronecrófagos (Scarabaeinae) en tres zonas con diferente manejo al interior de un agroecosistema localizado en el norte de la Península de Yucatán. A lo largo de un año de muestreo sistemático se encontraron 17 especies de los géneros Canthon, Canthidium, Deltochilum, Pseudocanthon, Malagoniella, Onthophagus, Phanaeus, Copris, Uroxys, Sisyphus y Ateuchus. El área de vegetación secundaria tuvo la comunidad más diversa. En la plantación de Brosimum alicastrum (ramón) se encontró la mayor riqueza de especies. El potrero tuvo la menor riqueza y diversidad, pero en él se observó la mayor abundancia de Scarabaeinae en la estación seca. Las áreas con mayor cobertura arbórea tuvieron mayor diversidad y se encontró dominancia de las especies rodadoras sobre las cavadoras y de las especies de talla pequeña sobre las de tamaño grande. Nuestros datos muestran dos aspectos importantes: en el potrero (con riego) las especies de escarabajos extienden su actividad hasta el inicio de la época seca, mientras que las abundancias decaen en las áreas que no reciben riego; la posibilidad de que los Scarabaeinae neotropicales sean saprófagos oportunistas y tengan hábitos alimenticios especializados para disponer de otros recursos además del excremento. El ramonal beneficia al sistema completo pues provee de un espacio para la dispersión y permanencia de varias especies estenoecas a la cobertura vegetal. |
