I am interested in biotic and abiotic forces that alter the interactions of species in established and restored communities. My primary research now entails tests of dispersal limitation in tropical trees in the restoration of plant dispersal processes in an agricultural mosaic in southern Mexico. Recent projects include a large exclosure project at the Morton Arboretum with Joel Brown
in which we tested the effects of seed-eating by birds and foliage consumption by voles on the density, productivity, dominance, species richness, and diversity of synthetic tallgrass communities. Other projects along these lines involve rodent exclosures in Wisconsin, and several studies of the effects of burn season on the population and community ecology of tallgrass restorations. The point of all of the above is to use experimental restoration to explore the ramifications of biotic animal effects or abiotic fire effects in shaping community composition and biodiversity, using replicated communities that receive the same seeding composition.
Other research interests involve established communities. Presently I am collaborating with my former student Maria Miriti and S. Joseph Wright of the Smithsonian Institution on the spatial demography and interactions of Colorado Desert perennials in southern California. An earlier interest explored the interactions of tropical trees with insect seed predators and the birds and mammals that promoted or precluded seed dispersal in Central America. This was re-visited with my former student Norbert Cordeiro with studies of fragmentation, seed dispersal, and seedling recruitment of endemic trees in the Usambara Mountains of Tanzania. My graduates are doing or have recently done research in Brazil, India, Kenya, Mexico, Panama, Peru, Tanzania, and the USA.
A productive collaboration with John Lyne of the University of Iowa, now at the University of Pittsburgh, explored the rhetoric of science, including debate among scientists and the projection of expertise to non-scientists. Over the next few years I hope to explore issues of environmental ethics and issues of reductionism and epistemology with competent help in the humanities.
