We used ANOSIM (analysis of similarities) to test whether species
composition differed among disturbance intensities (logging,
shifting cultivation, and control) for each tree size class, saplings
(1 cm 6 dbh < 5 cm), treelets (5 cm 6 dbh < 10 cm), and adult trees
(dbhP10 cm) using the anosim function in the ‘‘vegan’’ package
(Oksanen et al., 2011) in R version 2.12.0
