Population
ecology, particularly of interspecific interactions
Selected
Publications
My general area
of interest is in population dynamics, particularly those of insect populations
involved in predator-prey, parasitoid-host, or other interspecific interactions.
I have been particularly interested in three topics: the effects of aspects
of parasitoid biology on population dynamics; the effects of population
spatial structure and metapopulation processes; and the application of
these ideas to conservation biology and biological pest control.
One current project
concerns the population dynamics of what I term "sublethal" parasitoids:
species whose hosts reproduce (though possibly at reduced rates) despite
being parasitized. The "feather-legged fly" (Trichopoda pennipes;
Diptera, Tachinidae), which parasitizes adults of its host (the southern
green stinkbug, Nezara viridula; Hemiptera, Pentatomidae), has been
used in experimental and observational studies describing this interaction.
Mathematical models are now being used to explore the possible dynamic
consequences of sublethality; these effects tend to be stabilizing but
can be complex when age- or density-dependent effects are considered.
As an outgrowth
of these studies of the Trichopoda–Nezara interaction, I have collaborated
on studies of the impact on native bugs of Trichopoda and other
parasitoids introduced to Hawai'i to control the stinkbug.
Another major research
focus is on the dynamics of parasitoid-host "metapopulations" (ensembles
of populations). Simulation models are being used to determine the circumstances
under which parasitoid-host metapopulations persist; factors of interest
include various forms of environmental variability, more complex spatial
structures and density-dependent dispersal.
