Table 1. Results from a phylogenetic analysis of covariance (Smaers and Rohlf, 2016).
Results relate to tests of differences in intercept among groups with the slope held constant. ‘Others’ refers to all species in the sample not included in the other allocated groups. The analysis includes the comparison of multiple treatment groups (group a ‘versus’ group b) to a control group (‘|’ group c). High, medium, low indicates which groups have the highest, medium, and lowest trait values.
