	abstract = {This study examines the functional attributes of Neotropical dung beetles, and, based on the analysis, evaluates the role of dung beetles in pastures and tropical dry forest in El Salvador. Dung beetle diversity was lower in pastures than in forests. However, the total biomass of beetles at similarly-sized dung baits was frequently higher in pastures. Diversity loss followed structured patterns: (1) carrion and fruit feeding beetles were well represented (species number) in the forests but were largely absent from pastures; (2) large ball rollers and small fast tunnellers were present in forests but were absent from pastures; (3) large fast tunnellers and small slow tunnellers were poorly represented in pastures com- pared to forests but the few species that survived in pastures attained extremely high popu- lations; and (4) each functional group in the species-poor pasture assemblages was divided almost equally into day and night active species. Substrate and habitat generalists that were present in both the forests and pastures were attracted to fruit and carrion in forested habitat but not in open pastures. In open habitats, Xies and other insects may be the principal decomposers of decaying fruit and carrion. },

	abstract = {We studied the diversity of dung beetles in three different habitats in the Lacandona Forest, Chiapas, Mexico. We found a total of 49 species. Of these, 44 were in well-preserved forests (SC) within the limits of the Montes Azules Biosphere Reserve, 42 in fragmented forests (SF), and 13 in cattle pastures (PZ). These two latter habitats were part of a fragmented landscape. Even though the species richness between the two forest habitats is similar, there is a change in guild composition and structure. About 12\% of the species were exclusively found in SC, while 4.1\% and 2\% were exclusive of SF and PZ respectively. b diversity was the most important element for overall diversity (c), above that of the local richness (a). Within well-preserved forests, species composition changes substantially, even among neighboring sites. Species diversity within the landscape seems to depend on canopy coverage, soil temperature and geographic distance between sites. Functional groups vary with the habitat. Large-bodied, nocturnal species with specific requirements of soil temperature and compaction are more sensitive to anthropogenic changes. In cattle pastures there is a larger number of heliophilic species, with a higher percentage of small-bodied and roller beetles.},
