Table 2. Results of a phylogenetic ordination analysis using canonical correspondence analysis for diets of 25 species in a snake community in temperate South America, using the use of habitat as a covariate.

Taxa	Variation	Variation %	F	P
Dipsadinae	0.93	48	16.68	0.0006
Alternatus	0.26	13	5.74	0.0305
Micrurus	0.19	10	5.11	0.0038
Leptophis	0.14	7	4.49	0.0196

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 yielded individual P≤0.05.
