Table 1.

Summary of results from Mantel and partial Mantel tests for the epiphyte community data (r = Pearsons correlation, calculated through mantel tests). Geo, geographical distance between trees; area, surface area difference between trees; genetic distance, Nei's genetic distance between trees; epiphyte community, community difference between trees. The first row, in bold, indicates the correlation between epiphyte community and genetic distance, with the appropriate matrices held constant in a partial Mantel test. In the first column, the matrices held constant in a partial mantel test are indicated in parentheses. The numbers in parentheses in the presence/absence and abundance columns indicate the p-value for the Mantel test, calculated using 9999 permutations.
