Logits = log[(%/100-%) ]in response to different static day lengths (PPD) in down- and up-selected lines after 10 generations of selection plus two generations in a common environment. Column Descriptions: PPD: Photoperiod - Number of hours of light within a 24h period. East_UP: logit of Percent pupation in the up-selected East population when reared under a given PPD North_UP: logit of Percent pupation in the up-selected North population when reared under a given PPD West_UP: logit of Percent pupation in the up-selected West population when reared under a given PPD East_DOWN: logit of Percent pupation in the down-selected East population when reared under a given PPD North_DOWN: logit of Percent pupation in the down-selected North population when reared under a given PPD West_DOWN: logit of Percent pupation in the down-selected West population when reared under a given PPD Special Rows: a: Intercept of regression line through logit scores b: Slope of regression line through logit scores r2: (r^2) from regression analysis P: P-value testing regression slope = 0 CPP: day length at which logit predicted from regression = 0.00
