1Of 92 available S. altissima and 175 available S. gigantea ramets. 2Attacked centroid minus available centroid (PC1 and PC2 components). A positive entry means that ramets with a large PC score are more likely to be attacked. 3“Small” if the two attacked trait spaces are adjacent (Figure 2(b)), and “large” if the two attacked trait spaces are distant (Figure 2(c)). 4This test is informative only when the marginal trait-space test is not significant. |
