My
research interests range broadly in evolutionary and behavioral
ecology. Special interests include life history theory, mating
system theory, and optimal foraging theory. I emphasize experimental
approaches to the study of adaptation, particularly with species
that display geographical variation in the characteristics of
interest. Current research uses birds as study systems, but
taxonomic interests include most vertebrates and insects. Current
projects include 1) the evolution of sexual dichromatism and
cavity-nesting in the Hawaii Akepa, 2) the evolution of reproductive
rate and permanent monogamy in tropical House Wrens in lowland
central Panama, and 3) evolution of introduced birds in Hawai`i.
I am closely associated with researchers in the Hawaiian Evolutionary
Biology Program in attempts to use both native and introduced
species in Hawai`i as model systems for understanding evolutionary
processes.
