Community assembly dynamics over small spatio-temporal scales: an example from fence posts in Costa Rica.

Community assembly is the study of how plant communities form, interact, and persist over time. Using epiphytic lichen communities on wooden fence posts (age 0.5 - 15 years) in a cloud forest of Costa Rica (elev. ~2500 meters), I examined the colonization of epiphytes within this early successional stage. I found that lichen community diversity increases with age of fence posts and that only a small number of the 27 epiphytic morphospecies found on the fence posts were responsible for a majority of the difference in percent abundance cover. Furthermore, the growth and community dynamics differed drastically based on the direction of the side of the post (east/west/north/south), with some sides undergoing the species replacement characteristic of classical succession, while other sides did not. Because of lichens' importance in large scale succession, as habitats for microinvertebrates, and as indicators in pollution monitoring, understanding how these communities assemble, persist, and evolve is an important topic in community ecology worldwide.
