G.  aHow do earthworms affect microfloral and faunal community diversity?  c1995  aMuch of the work regarding earthworm effects on other organisms has focused on the functional significance of microbial-earthworm interactions, and little is known on the effects of earthworms on microfloral and faunal diversity. Earthworms can affect soil microflora and fauna populations directly and indirectly by three main mechanisms: (1)comminution, burrowing and casting; (3) dispersal. These activities change the soil's physico-chemical and biological status and may cause drastic shifts in the density, diversity, structure and activity of microbial and faunal communities within the drilosphere. Certain organisms and species may be enhanced, reduced or not be affected at all depending ontheir ability to adapt to the particular conditions of different earthworm drilospheres.  asoil fauna  aMicroflora  aMinhoca  aCommunity  aComunidade  aDiversidade  aDiversity  aEarthworm  aFaula do solo  aSoil microflora  aSoil process  tPlant and Soilgv.170, p.209-231, 1995.
