	abstract = {The effect of a moderated altitudinal variation (500 m) on the dung beetle communities is studied in highland grasslands of the Iberian Central System. The more is the altitude the less is the richness of these communities. This decrease is more important in the warm south slope stations than in the north slope stations, since south slope grasslands are inhabited for a larger number of species with small populations, which are unable to colonize grasslands of the highest altitude. The Scarabaeidae species are the principal component of this latter group. However there is not an altitudinal variation in the abundance. In addition, north-slope dung beetle communities have a lesser number of species, but similar number of individuals and larger biomass. These results are in accordance with a density compensation pattern.},

	abstract = {1. The effects of a change from sheep to cattle grazing on dung beetle communities were studied under Mediterranean conditions. 2. Five years after the beginning of a change in the grazing regime, dung resources had increased by a factor of 3 and led to a 3-fold increase in beetle numbers and a 2.5-fold increase in biomass. 3. Marked re-adjustments towards a new equilibrium occurred in the dung beetle communities, with drastic changes in the relative frequencies of many species. Dwellers became dominant, coexisting with medium and large tunnellers. No significant changes in species composition occurred during the same period. 4. Mediterranean pasture ecosystems show a strong resilience allowing them to re-adjust rapidly to the processes of recycling organic matter.},
