Finally, phenotypic plasticity in the hatching fraction, as measured by PI HF from joint regression analysis, showed marginally significant differences among populations ( F 5,31 = 2.374, p = 0.062; Figure 3 ) and considerable variation among clones (ranging from −0.268 in ATA250 to 5.013 in ATA210; see Appendix S1 : Figure S2 for within‐population variability).
