Organisms as Ecosystems: Exploring the Microbiome of Plants Kraichak, Ekaphan [1]. Diverging Succession of Bryophytes on Leaf Surface. Communities of leaf-dwelling (epiphyllous) bryophytes offer unique opportunities to study succession, because each leaf harbors a spatially and temporally discrete community that can be obtained in a large number for replicates. In this study, I examined successional patterns of epiphyllous communities on hundreds of Inocarpus fagifer leaves, using chronosequence and long-term observation approaches. Over time, the richness increases along with significant shifts in community compositions. The dominant species, Leptolejeunea epiphylla, is found to be the common first colonizer that contributes the most to the changes in richness and composition. Communities on the older leaves were also more varied than those on the younger leaves, suggesting the diverging successional trajectories. These patterns indicate the role of facilitation by early successional species, as well as the stochastic processes in the highly dynamic environment of leaf surface. Broader Impacts:
