	abstract = {This paper analyzes the diversity of dung and carrion beetles (Scarabaeinae and Silphidae) in four human-induced habitats of a disturbed tropical montane cloud forest: polyspecific shade coffee plantations, monospecific shade coffee plantations, tropical montane cloud forest fragments, and clear cuts. The four habitats had similar richness, species composition, and assemblage structure of dung and carrion beetles. Differences were found in abundance and biomass levels for the four dominant species in the landscape. Dung beetles were more abundant than carrion beetles, but the biomass was higher for the latter. Carrion beetles were seasonal, while dung beetles were clearly not. When forest fragments and shade coffee plantations were compared to other similar habitats in the region, the same general pattern was observed. However, forests with high disturbance and monospecific shade coffee plantations had lower species richness than forests with low and medium disturbance and polyspecific shade coffee plantations. Thus shade coffee plantations maintain connectivity between patches of cloud forest in a landscape that is strongly affected by human activities. Protecting landscape diversity appears to ensure high species richness.},

	abstract = {The effects of the lack of maternal care on offspring survival of the sub-social beetle Copris incertus Say (Coleoptera: Scarabaeidae: Scarabaeinae) were tested experimentally by excluding the female and determining the most vulnerable stage of development. Time budget studies were also conducted to determine the amount used by 10 females during the whole cycle from the making of the nest to the emergence of adults. A Kruskal{\textendash}Wallis test and the subsequent non-parametric multiple comparisons showed a significant difference in survival between nests cared for by the mother and nests where the mother was excluded. Key-factor analysis showed that the absence of parental care affected offspring survival in the transition from the pupal to adult stage. Time budget studies indicated that, whether active or inactive, females were in direct association with the brood balls. Balls that received no care (in experimental exclusions or where the female abandoned the nest) were invaded by the fungi Metarrhizium anisoplae and Cephalosporium sp., which covered the surface and the inner part of the ball, considerably affecting pupal survivorship. Results show that sub-social care increases the probability of juveniles reaching adulthood. },
