Research Description
Tropical forest dynamics, plant-soil and plant-fungal interactions, seed ecology
My research concerns the population and community ecology of tropical forests, with a particular interest in understanding how soil nutrient availability and soil microbial communities shape the composition and diversity of tree communities. Much of my work is carried out with collaborators at the Smithsonian Tropical Research Institute, in Panama, where I am a Research Associate Scientist. My work is carried out principally on Barro Colorado Island in the Panama Canal Watershed, or at the Fortuna Forest Reserve and Volcan Barú in western Panama where I established and maintain a network of forest dynamics plots that encompass a wide range of soil nutrient availabilities and elevation (700-3200m).
Current projects explore:
- seed-infecting fungi as a model system for understanding how plant-pathogen interactions and plant defense traits influence abundance and coexistence
- role of soil nutrient availability in structuring tree communities and plant functional traits
- role of wood nutrients as a plant nutrient store in nutrient-poor soil and as a determinant of wood decomposer community composition and decay rate
