Other claims from this paper (15)

Intervention effect High N inputs increased soil N availability in forests dominated by white spruce.
Intervention effect High N inputs decreased soil pH and base cation availability.
Intervention effect High N inputs increased foliar N in white spruce.
Intervention effect High N inputs decreased foliar P, Mg and K in white spruce.
Intervention effect High N inputs increased tree growth in white spruce forests.
Intervention effect High N inputs led to replacement of mosses by grasses.
Observation At the six lowest N sites 144 ectomycorrhizal fungal species were encountered.
Observation At the six highest N sites only 14 ectomycorrhizal fungal species were encountered.
Association Total species richness declined with increasing mineral N availability in the organic horizon (1994 and 1995).
Association Total sporocarp abundance declined with increasing mineral N availability in the organic horizon (1994 only).
Association Nitrophobic taxa Cortinarius, Russula, Tricholoma, Lactarius and Hebeloma declined in species richness or abundance with increasing organic horizon mineral N.
Observation Redundancy analysis identified two environmental axes that explained 62% and 7% of the variation in the EMF community.
Observation The final model included mineral soil base cations, organic horizon mineral N and organic horizon net mineralization as environmental variables.
Mechanism The results support the hypothesis that long-term N inputs alone may lead to loss of EMF sporocarp diversity.
Recommendation EMF should be considered in establishing critical loads of N.
