FIGURE 2.
A. SS-STP applied to colony area means for male PC1 scores in the L. glaucescens-occidentalis complex, morphotypes pooled. Population means are listed to the right of colony alphanumeric codes. The pie diagrams at each locality represent the mean of the character at that locality, scaled as a percentage of the total range of means across all colonies. Vertical bars represent maximally non-significant subsets of population means.
B. SS-STP applied to colony area means for mantle neutral value in the L. glaucescens-occidentalis complex, morphotypes pooled, sexes combined. Mantle neutral value colony means ranged from dark gray (SNC32) to light gray (KACH2).
