Table 1. Results of a phylogenetic ordination analysis using canonical correspondence analysis for the diets of 25 species in a snake community in temperate South America.

Taxa	Variation	Variation %	F	P
Dipsadinae	1	39	11.51	0.0035
Micrurus	0.4	15	5.59	0.0062
Helicops	0.27	10	5.47	0.0101

Clades are ranked by the amount of variation explained at each node. Percentage of the variation explained (relative to total unconstrained variation) and F- and P-values for each variable are given (9,999 permutations were used) for each main matrix. Note that no groups used for variable selection of variable yielded individual P≤0.05.
