Table 2.

Canonical analysis of principal coordinates (CAP) of the effects of species (Schiedea kaalae or S. hookeri) and time of day on floral scent composition. (A) ANOVA-like permutation test (n = 99999 iterations) of each term. (B) Compound scores on the first CAP axis, which discriminated between the species. Absolute scores ≥ 0.02 are included. Negative values indicate compounds associated with S. hookeri, and positive values indicate compounds associated with S. kaalae.
