Schweizer D, Gilbert GS, Aizprua R.2014. Do young tropical restoration plantations exhibit a phylogenetic pattern that suggests the influence of biotic processes affecting species composition?PeerJ PrePrints2:e625v1https://doi.org/10.7287/peerj.preprints.625v1
One approach in forest restoration is to plant trees that will establish an initial canopy to promote forest recovery through natural recruitment of other species. Here we evaluate the patterns of either phylogenetic overdispersion or phylogenetic clustering on community assembly beneath seven different single-species tree plantations. We expected the presence of negative biotic interactions between closely related overstory and recruiting tree species, as well as among related recruiting species, to lead to phylogenetic overdispersion. We found no evidence for inhibition of close relatives of the overstory tree species. However, we found more understory species than expected that were very distantly related to the overstory tree when the canopy was comprised of Fabaceae species, which lead to the presence of similar species in the understory of legume species. We found weak phylogenetic patterns among species in the understory community that suggest the presence of random processes of community assembly, maybe due to the young age of the understory communities studied.

Naturally colonizing species sampled
Table S1 - Naturally colonizing species sampled. Habit codes S, U, M and T are free-standing, species with maximum heights of 5, 10, 20 and > 30 m, respectively. These species are found in the old-growth forest of Barro Colorado Island, Panama. Most habits and dispersal syndromes come from databases provided by Joe Wright and published in Wright, 2007 ; Wright et al., 2007 ; Wright et al., 2010 . Other sources noted. Species names with an (*) means that those species were observed at frequencies of five stems or more.
Newick file of species of understory natural recruits and overstory species. Species names are coded using the APG3 six-letters coding system, which is the first four letters of the genus plus the first two letters of the species (see Table S1 for reference).
