	abstract = {1. To provide reliable tools for landscape management in tropical regions, it is important to recognise the emergent properties of landscape heterogeneity and to understand their influence on different components of biodiversity. 2. The effects of habitat type, patch size and shape, canopy cover, distance between habitats, and elevation were examined on the partitioned diversity (alpha, beta and gamma) of dung beetles in a transformed landscape in southern Mexico. 3. In total, 4109 individuals belonging to 28 species of dung beetle were recorded in the entire landscape. Alpha diversity was similar among habitats, although species com- position was more similar between forest remnants and living fences than between living fences and pastures. Beta diversity was related to differences in elevation and distance between habitats. The distance between fragments was significantly correlated with the mean number of beetle captures and species richness per site. Gamma diversity depended more on species turnover (beta diversity) than on local species richness. 4. In general, living fences and pastures with trees, and small forest patches retain a significant proportion of the fauna typically associated with pristine forest habitats. The remaining tracts of forest, along with the contemporary landscape elements may offer suitable habitats for future recolonisation by other insect species in heavily disturbed landscapes in tropical Mexico.},

	abstract = {Biological diversity conservation within natural reserves has been prioritized, but conservation efforts outside protected areas (where most human activities take place) have been very little considered. In this scenario, an alternative agricultural practice that may reduce the impacts of fragmentation in outer landscapes is a perforation process, which involves conservation in agricultural fields surrounded by continuous forests. Such practices enhance the positive impact of ecological services on fields. In this study we analyzed the biological diversity state in perforation fields and their surrounding forests. The analysis was done using dung beetles as biological indicators. A nested pattern in dung beetles distribution was found, which ordered the surrounding continuous forest sites as the ones with the highest species richness, followed by the perforation fields, and placed the fragmentation practice fields (continuous agricultural fields surrounding forest patches) with the lowest one. Indicator species for perforation fields and surrounding continuous forests were chosen. In general, perforation practice fields differed in composition, based upon functional groups richness and identity; it also contained a higher species richness than the fragmentation practice. Agricultural practices that enhance biological diversity conservation such as perforation, should be recommended and considered in natural resource management by local communities in order to take advantage of ecological services that otherwise may be gradually lost.},
