Abstract
Baited pitfall traps were used to sample the Scarabaeinae dung beetle fauna in six habitats in South Texas. Habitats were defined according to their soil and vegetative cover characteristics. Most of the 19 scarab species collected displayed marked associations with a particular soil type (sand or clay) and (or) cover (shade or open). The result is the existence of distinct communities of coprophagous beetles, which differ in their species composition, species-abundance relations, and efficiency of dung removal. A discussion of the evolution of these habitat associations and the ecological implications for pasture ecosystems is included.
