In the Hawkes lab, we address broad questions in plant, microbial, and
ecosystem ecology that are important for understanding fundamental
community and ecosystem dynamics. We are also interested in how
communities and ecosystems are affected by biological invasions, altered
climate, and other environmental changes. We use a variety of genes to
ecosystems approaches for experiments in the field, greenhouse, and lab.
Examples of ongoing research projects in the lab include:
- The role of fungi in community and ecosystem responses to drought
- Local specialization of fungi to precipitation
- Ecophysiological and genomic responses of switchgrass to future climate change
- Legacy effects of exotic plants and their importance in landscape restoration
- Links between aboveground and belowground community structure
