	abstract = {The dung burial ability of two congeneric ball-rolling dung beetles, Allogymnopleurus thalassinus Klug 1855 and Allogymnopleurus consocius Peringuey 1900 was investigated in field experiments in three different textural classes of sod at contrasting moisture levels in order to seek an explanation for their strong associations with particular soil types in the field. The success and depth of burial of dung balls was measured and was strongly associated with sod hardness. Both species were unable to bury dung in soil with a hardness greater than 2 kg/cm-2. Beetles were able to utilize both sand and clay sods for dung burial sites provided the soil was soft. Hard-setting sandy clay soils exceeded the hardness threshold except during brief periods following rain but the deep sand and self-mulching clay soils did not exceed this threshold even when dry. The restriction of each species to soft soils of a particular texture is discussed.},

	abstract = {The immature stages of two dung beetle species Allgymnopleurus thalassinus Klug 1855 and Allogymnopleurus consocius Peringuey 1900 were reared in the laboratory in three textural classes of soil under different conditions of soil moisture in order to determine whether differential mortality in different soil types could help explain the strong associations between soil type and beetle abundance in the field. Larvae survived well in dry and moist soil treatments, regardless of soil type, but poorly in wet soil treatments. The effect of soil moisture on the distribution of both species in different soil types is discussed.},
