	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 = {In this study we discuss the reasons for using indicator groups to measure biodiversity at the species level ("organismal diversity" sensu Harper and Hawksworth). We further explore our previous proposals for the use of dung beetles belonging to the subfamily Scarabaeinae (Insecta: Coleoptera) as an indicator group for studying the types of communities found in tropical forests and derived formations, particularly those created by human activity. We present a method for obtaining quantifiable information that allows comparative studies to be done, as well as an analysis of the effects of human activities that result in the alteration, fragmentation and destruction of natural communities. Although emphasis is placed on the indicator group and the communities selected, we propose that this analysis of biodiversity can be used with other groups and in different community types. The arguments we present for the use of indicator groups can be applied to different ways of studying biodiversity at the species level, however this study focuses on presenting appropriate methodology for ecological analysis; that is, for the study of local biodiversity as an element for the interpretation of community structure and function.},
