*Diversity indices for PFTs and PFC (Plant Functional Complexity) (Gillison and Carpenter, unpubl. 1999; Gillison 2000);
First line = linear “r” correlate; second line = “P” value.
Tree wt1 and tree wt2 = tree biomass based on allometric equations of Ketterings et al. (2001) and Brown (1997), respectively.
