INVASIVE PLANTS AND SOIL FEEDBACK
We have a limited understanding of how invasive plants alter soil-plant interactions and, consequently, plant communities. We are investigating the relationship between functional groups of soil microbes in communities and and net soil biotic effects on plant growth and fitness.
FUNCTIONAL ECOLOGY OF ENDOPHYTES
In an effort to gain a better understanding of the diversity and functional role of plant fungal endophytes we are using metagenomics. We also isolate endophytes into pure culture to test how they affect their host.
MYCORRHIZAS AND SOIL FOOD WEBS
Mycorrhizal fungi pump nutrients and carbon into the soil food web. However, little is known about their impact on higher trophic levels. We are filling in this knowledge gap.
