My research centers on the ecology
of mycorrhizae, the frequently mutualistic
association between plant roots and fungi.
I am particularly interested in how other
biotic and abiotic forces in the environment affect mycorrhizal populations
and communities, and how these changes in turn influence host plant
performance. One current
project examines how beneficial interactions such as mycorrhizae and
nurse plant associations interact with herbivores and parasites to
influence ecotonal shifts in pinyon-juniper woodlands.
A second project looks at the influence of terrestrial vertebrates
and mycorrhizal fungi (and their interaction) on seedling growth,
mortality and diversity in tropical rainforest.
