Las alteraciones del paisaje pueden afectar los ensambles de escarabajos donde las especies sensibles pueden desaparecer y las poblaciones de especies altamente adaptadas pueden aumentar. Se evaluó la diversidad de escarabajos en un bosque restaurado y tierras de cultivo del bosque seco tropical de Ecuador. Se realizó trampas de caída y recolección manual en tres sitios; dos sitios con tierras de cultivo y un sitio con remanente de bosque secundario. Se usaron cuatro tipos de cebo para atraer escarabajos que se alimentaban de diferentes recursos para lograr una evaluación preliminar adecuada del ensamble de escarabajos. Este estudio es la primera aproximación a la caracterización de la comunidad de coleópteros en el bosque seco tropical de Manabí. Reportamos 64 morfoespecies asociadas con tierras productivas y bosques fragmentados y destacamos la presencia de algunos géneros resilientes como Canthon, Canthidium, Deltochilum y Euspilotus que se han adaptado con éxito a ecosistemas perturbados; por otro lado, Phyllophaga y Diabrotica también fueron detectados principalmente en el paisaje de cultivos. En general, presentamos una línea de base de la composición de escarabajos en un bosque secundario y tierras de cultivo, y brindamos información relevante para una evaluación adicional del cambio de uso del suelo en la región. Landscape alterations may affect beetle assemblages wherein sensitive species can disappear, and highly adapted species populations can increase. Beetle diversity in a restored forest and cropland was assessed in the tropical dry forest of Ecuador. Pitfall trapping and manual collection were performed in three sites: two sites with cropland and one site with secondary forest remnant. Four bait types were used to attract beetles feeding on different resources to achieve an adequate preliminary beetle assessment. This study is the first approach to characterizing the coleopteran community in the tropical dry forest of Manabí. We report 64 morpho-species associated with productive land and fragmented forests and highlight the occurrence of some resilient genera like Canthon, Canthidium, Deltochilum and Euspilotus that have successfully adapted to disturbed ecosystems; on the other hand, Phyllophaga and Diabrotica were also detected mainly in the crop landscape. Overall, present a baseline of the beetle assemblage composition in a secondary forest and cropland, and provide relevant information for further assessment of land use change in the region. 

Our aim was to characterize the Scarabaeinae fauna from a rupestrian field formation at APA de Cafuringa, DF, Brazil. We made seven samples between 2007 and 2009 using baited pitfall traps. We collected 602 individuals belonging to 27 species and 13 genera, of which 17 were identified at species level. The majority of species caught has wide geographical distribution in Brazil and South America and do not seem to be specialized in 'campo rupestre' formation. Two species, Canthidium marseuli and Canthon lamproderes have restricted geographical distribution, being present in the central Brazilian highlands. C. marseuli and C. lamproderes are probably restricted to rupestrian fields since they have been registered only for this formation in Brazil, which indicates that these species need attention in relation to the conservation of theirs populations and habitats.
