Current Emphases, Studies, Projects

• Growth rates and physiological characteristics of exotic and native Hawaiian trees and shrubs under light and nutrient variation. (with A. Uowolo)
• Economic and ecological cost-benefit assessment of the invasive tree, Psidium cattleianum (strawberry guava), in the Hawaiian Islands (with J. Yanagida, U. Hawaii CTAHR)
• Demography of the invasive tree, Psidium cattleianum, in mid-elevation moist Hawaiian forest. (with T. Johnson, A. Uowolo, R. Nagata, and C. Perry)
• Assessment of invasiveness among exotic plants in the Hawaiian Islands (with C. Daehler and the Hawaii Exotic Plant Evaluation Committee)
Impact of the biological control agent, Colletotrichum gloeosporioides v. miconieae, on the invasive tree, Miconia calvescens (with P. Conant and E. Kilgore, Hawaii DOA).
