Conservation of ectomycorrhizal fungi: exploring the linkages between functional and taxonomic responses to anthropogenic N deposition by Lilleskov, E.A., Hobbie, E.A., Horton, T.R.

“…Anthropogenic nitrogen (N) deposition alters ectomycorrhizal fungal communities, but the effect on functional diversity is not clear. In this review we explore…”

15N in symbiotic fungi and plants estimates nitrogen and carbon flux rates in arctic tundra by Hobbie, J.E, Hobbie, E.A

“…When soil nitrogen is in short supply, most terrestrial plants form symbioses with fungi (mycorrhizae): hyphae take up soil nitrogen, transport it into plant…”
