Research Interests Plant Ecology. Current research on demography and life history of plant populations, effects of habitat fragmentation on genetic structure and ecological traits, modeling extinction probability and population viability, life history adaptations of scrub plants to fire, fire effects on plant population dynamics, restoration ecology, plant conservation, and the ecology of introductions. Study species include scrub balm (Dicerandra frutescens), wedge-leaved Eryngium (Eryngium cuneifolium), Highlands scrub hypericum (Hypericum cumulicola), Carter’s mustard (Warea carteri), and several other rare plant species. Some research projects also involve community dynamics in Florida sand pine scrub, and other upland plant communities, including the role of fire
