Table 3. Size difference (in mm) between traits measured in isolated versus continuous populations (where the difference is isolated—continuous), conditional on sex and rearing condition.

Note:
Rearing conditions are given for wild field-caught insects (field), those reared under environmentally controlled conditions (laboratory) and a general category where all observations are grouped regardless of rearing condition (general). Estimates are the means ± SD of the posterior distribution of the differences between populations, generated directly from the regression models (for details see Appendix S1).
