Fruiting response of ectomycorrhizal fungi to nutrient additions claudia victoroff, nina hilmarsdottir-puetzer, and amy sayre giovati
4. Why collect sporocarps?
•Indicates nutrient effects on
the fitness of mycorrhizal fungi
•Surveys a significantly larger
area
•Results can be compared to
analyses of community profiles
in soil samples from the same
plots with the Illumina MiSeq
approach
Amanita muscaria
5. •Is ectomycorrhizal fruiting
body abundance impacted by
N, P, NP, additions?
•Is there variation in nutrient
response according to season?
•How does overall community
composition vary according to
nutrient manipulations and
seasonal variation?
