GRADUATE PROGRAM ROLE:
Graduate Students focus on a variety of plant ecology and conservation biology issues, focusing on seed ecology or on cedar glades. This ecosystem is best developed in middle Tennessee, a hotspot of plant endemism and rarity, and is critically imperiled. Examples of graduate projects include investigating the invasiveness of the exotic shrub Chinese privet, determinants of species richness in cedar glades using GIS, and effects of climate change on management of rare bladderpods. External and in-house grants support graduate research.
