Figure 3.

Sites whose trait mean are different from the presumed optimum are associated with lower between-isofemale line variance compared with those close to the optimum along the Kirrama ecotone. Deviations from optima are the absolute distances between the site mean and the fitted line for the significant regression for CCT observed at Kirrama (figure 1). The correlation is significant (r=−0.67, p=0.048). Sites represented by less than five isofemale lines are represented by open squares.
