| Over
the last ten years we have been examining how seed and seedling
characteristics influence recruitment success, habitat requirements, and
competitive interactions among pioneer species on Barro Colorado Island,
Panama. Our current work concerns seed germination ecology, determinants of
seed persistence in the soil, and plant-fungal interactions. In
a collaboration with Rachel Gallery (Oxford University)
and Betsy Arnold (University
of Arizona) we are looking the diversity, biogeography, evolutionary relationships and life-histories
(mutualistic; pathogenic; saprobic) of communities of seed-infecting fungi that are
found associated with Cecropia seeds across the range of this genus of pioneer trees in Central and South
America.
