Non-invasive Population Estimation
I study population- and community-level processes involving both plants and animals, with my primary research focus being the population ecology of foundational wetland and coastal plant species. The wetland species I have studied most extensively is the intertidal salt marsh grass, Spartina alterniflora, which is widely used for habitat restoration owing to its ability to create marsh conditions conducive to colonization by other endemic marsh organisms. Historically, the principal theme of my S. alterniflora research has related to genetic mechanisms underlying long-term population and community viability. More recently, I have begun to investigate the importance of interactions between S. alterniflora and invasive plants like common reed (Phragmites australis), as well as microbial decomposers and invertebrate herbivores, in determining the capacity of salt marshes to remain viable in the face of climate change.
