A da  aArbuscular mycorrhizal fungi in a semiarid copper mining area in Brazil.  c2005  aThe accurrence of arbuscular mycorrhizal fungi AMF in a copper mining area was investited. Soil samples were collected from six sites at the Mineração Caraiba, Bahia State, northeastern Brazil, comprising: (1) a site that receives the waste product; (2) a site that receives low grade deposits; (3) the interface between the the caatinga and site 1; (4) the surroundings of the industrial area; (5) the site for extracting topsoil for land filling; (6) the preserved caatinga. Thirty-two plant species were identified around the collection locations. Trap cultures were maintained in the greenhouse for 3 months, using bahia grass (Paspalum nottum Flügge) as the host plant. Spores were extracted from soil and 21 AMF species (15 Glomus and one of each of Acaulospora, Archaeospora, Entrophospora, Gigasopra, Paraglomus and Scutellospora) were identified. In site 1, plants or AMF were not found during the dry season. Site 6, with native vegetation, had the hisghest number of plants and AMF species. The disturbed sites showed less plant diversification, with the community of AMF being quantitative and qualitatively affected by disturbance.  avesicular arbuscular mycorrhizae  aMetal Pesado  aMicorriza Vesicular Arbuscular  aHeavy metal1 aTRUFEM, S.
