Epiphyllous Cryptogams as a System for Studying Metacommunity Processes.
Tropical broad leaves or “phyllospheres” offer unique opportunities to study meta-community dynamics because they harbor spatially and temporally discrete, as well as highly diverse, communities of cryptogams (bryophytes and lichens). In this system, habitat patches (leaves) can harbor incredibly rich assemblages of species at a size that lends itself to analysis of the effects of spatial scale on meta-community processes. In an ongoing study, I am quantifying cryptogam diversity in these leaf systems to explore the possibility of using this system to understand and ultimately test the generality of theoretical predictions of community assembly and co-occurrence theory developed at broader spatial scales. Preliminary results suggest that host specificity is less important than leaf architecture and that stochastic processes are more important than deterministic processes in determining the cryptogam assemblage of each leaf.
