| Abstract | Theiversityf nematode-trapping fungi (NTF)n two lead (Pb) minesn Yunnan Province, China wasnvestigatedn 2004. In total, 20 species belonging to five genera weredentified from 500 samples collected at the Lanping and the Huize mines. Pb concentrations ranged from 216 approximately 7,150 mg/kg for the former and 132 approximately 13,380 mg/kg for the latter, respectively. The fungi wereividednto five groups basednifferent trapping mechanisms. The trapping-net producer group contained the largest numberf species, with nine. Two predators, Dactylellina ellipsosporum and Arthrobotrysligospora, were found at frequenciesf 32.85% and 15.41%, respectively. Theiversityndexesf NTF were positively correlated with Pb pollution levelsn both the Lanping Mine (r=0.66) and the Huize Mine (r=0.72), suggesting that theistributionf NTF was not negatively affected by Pb contamination. For most strainsf a given species, there was no significantifference (P>0.01)n the Pb tolerance between the strainssolated from habitats with lowr high Pb concentrations. However, Pb toxicity exerted adverse effectsn trap formation and predacious capabilityf fungi. Weiscuss the possible metal tolerance mechanisms and their relationships to the survival strategyf NTFn Pb-polluted environments. |
