The occurrence of arbuscular mycorrhizal fungi (AMF) in a copper mining area was investigated. 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 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 notatum Flügge) as the host plant. Spores were extracted from soil and 21 AMF species (15 Glomus and one of each of Acaulospora, Archaeospora, Entrophospora, Gigaspora , 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 highest 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.
对巴西东北部巴伊亚州卡赖巴矿铜矿区丛枝菌根真菌（AMF）的出现情况进行了调查。从卡赖巴矿的六个地点采集了土壤样本，这些地点包括：（1）接收废品的地点；（2）接收低品位矿床的地点；（3）卡廷加与地点1之间的交界处；（4）工业区周边；（5）用于填埋的表土提取地点；（6）保存完好的卡廷加。在采集地点周围鉴定出了32种植物。以巴伊亚草（雀稗）作为宿主植物，在温室中维持诱捕培养3个月。从土壤中提取孢子，鉴定出21种AMF物种（15种球囊霉属以及无梗囊霉属、古孢囊霉属、内养囊霉属、巨孢囊霉属、类球囊霉属和盾巨孢囊霉属各1种）。在地点1，旱季未发现植物或AMF。具有原生植被的地点6拥有最多的植物和AMF物种。受干扰的地点植物多样性较低，AMF群落受到干扰的数量和质量影响。
