Shift in Ectomycorrhizal Community Composition in Scots Pine (Pinus sylvestris L.) Seedling Roots as a Response to Nickel Deposition and Removal of Lichem Cover

Description
Summary:Scots pine seedlings in a dry heath Scots pine forest were exposed to wet-deposited nickel and removal of lichen cover. Ni deposition impacts root colonization by indigenous ectomycorrhizal fungi in contrasting ways in intact and skimmed plots. The highest frequencies of tubercle morphotypes of ectomycorrhiza were measured in areas exposed to 1000 mg/m super(2)/yr Ni in the lichen-covered treatment. In skimmed plots these peaked after treatment with 10 mg Ni/m super(2)/yr. Lichen layer removal increased the value of the diversity index of the ectomycorrhizal fungal community.
