Fungal Community And Soil Responses To Invasive Alliaria Petiolata (Garlic Mustard), Soil Warming, And Nitrogen Deposition, Mark Alan Anthony

Doctoral Dissertations

Non-native, invasive plants can fundamentally alter soil fungal communities and edaphic properties. In this dissertation, I first measured fungal and edaphic responses and recovery to invasive, Alliaria petiolata (garlic mustard; Brassicaceae) eradication across Southern New England. I conducted an experimental eradication and tracked fungal communities and soil properties for three years in relation to reference uninvaded plots and actively invaded plots. Neither the fungal community nor soil properties recovered (i.e. became similar to reference uninvaded plots) following eradication, and I discuss how altered soil properties likely prevented fungal communities from recovering via environmental filtering. I also measured fungal and edaphic …
