Historical and current starvation resistance, desiccation resistance and mean longevity data from females in the desiccation selected and control lines. a Difference in average longevity between the selected and control populations. Difference in mean longevity was highest early in desiccation selection (near generation 30) [18] and then decreases to near zero toward the end of selection [21]. b Difference in mean survival time in a starvation environment of flies at age 15 days from egg. The TSO and TDO populations are not significantly different in starvation resistance. However, starvation resistance was significantly different during generation 130 of active desiccation selection [20, 22]. c Difference in mean survival time in a desiccation environment of flies at age 15 days from egg. Desiccation resistance differences were highest toward the end of selection (generation 200) and have since returned to close to zero [20, 21]. Error bars are mean ± 1 SEM
