nearly significantP = 0.079
While the distribution of best models for overall morphology, PC1, and PC3 were not significantly different than expected, for PC2 this was nearly significant (χ 2 = 6.8, P = 0.079, df = 3, simulated P = 0.11) Overall morphological variation was best explained by IBA in 4/10 species, IBH in 3/10, and 1/10 each for IBB, IBD, and IBE, respectively.
