<p>(A) Activity profiles of flies from selected (<i>PP</i>) and control (<i>CP</i>) populations under laboratory (LAB) and semi-natural (SN) conditions. The percentage of activity averaged over 8–10 successive cycles is plotted along <i>y</i>-axis and time of the day in h along the <i>x</i>-axis. Flies from selected populations showed increased activity during the morning peak under LAB as well as in SN. The day-to-day variations in light, temperature and humidity are plotted as error bars (SEM) on their daily profiles. Other details are same as in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0050379#pone-0050379-g002" target="_blank">Figure 2a</a>. (B) Percentage activity during the morning peak, daytime, nighttime in flies from selected and control populations. Flies from <i>PP</i> were more active during the selection window under LAB and SN. (C, D) Synchrony and accuracy under LAB and SN. Enhanced synchrony and accuracy in the phase of morning activity peak in <i>PP</i> flies persisted under SN. About 32 flies were used for each of the four replicate populations under each environmental regime. The mean values of four replicates and variance in terms of 95% comparison interval (95%CI) were used to draw emergence profiles and error bars. All other details are same as in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0050379#pone-0050379-g002" target="_blank">Figure 2</a>.</p
