As global change persists, changes in resource availability can influence plant-microbe interactions. To understand how resource availability can influence these interactions and species diversity, I focused this research on how varying nitrogen (N) levels affect root endophyte communities in the plant species Ammophila breviligulata, an ecosystem engineer in the dune system. I analyzed the relationship between nitrogen addition and microbial community composition across 60 plots treated with three nitrogen addition levels (control, low, and high) in a long-term experimental field site in the Lake Michigan dunes. I identified Ammophila breviligulata's root endophyte community after creating a culture collection and …

Lichens are one of the most successful mutualisms on Earth. The ecology and distribution of lichen symbionts likely influences their association and genetic structure . Two sister genera of lichenized fungi Niebla and Vermilicinia are endemic to the fog deserts on the west coast of North America. Species of Trebouxia, a genus of green algae found worldwide, are the associated photobiont partners to the Niebla/Vermilicinia species complex. Recent work demonstrated that Niebla and Vermilicinia are highly specific for only a few closely related Trebouxia molecular species (OTUs). This project examines the diversity and broad specificity of algae with lichen …
