Abstract Details

2008, Master of Science, Miami University, Botany.
Exotic plant invasion may result in the disruption of symbioses between plants and soil biota, potentially affecting plant fitness and community composition. I tested whether the invasive biennial Alliaria petiolata (garlic mustard) affects abundance and community composition of ectomycorrhizal fungi (EMF) associated with experimentally planted Quercus rubra (northern red oak) seedlings. Proportional EMF colonization, EMF species richness and diversity, and Q. rubra survival were lower for seedlings in a stand with high density A. petiolata than in a stand without A. petiolata. Community composition of EMF also differed between stands. A comparison of naturally occurring Q. rubra seedlings in a moderate vs. a low density site showed a trend toward less EMF with more A. petiolata, while richness and diversity did not differ. Though confounded by uncontrolled environmental variables, these results are consistent with A. petiolata negatively impacting ectomycorrhizal fungi, warranting more research on this indirect effect on native plants.
