  1. Group Slopes are pairwise comparisons between the allometric vectors of parasitic mode, Group Means are pairwise comparisons of Procrustes distance between modes after accounting for variation in size, and Allometry-free Group Means are the same comparisons as Group Means but using the residuals from regression of shape on size as shape variables. For pairwise comparisons, above the diagonal are p-values, and below the diagonal are z-scores. Below each pairwise comparison table are the values for the model (Type I Sum of Squares).
