File contains data on oxygen treatments and the maximum temperatures where heart beats were observed in Sceloporus tristichus eggs. Data on egg masses are also provided

The importance of factors in our models of flight performance and knockdown time.

<p>Importance equals the sum of Akaike weights for models that include the factor (or the probability that the factor would occur in the best model). A dash indicates that a factor was not considered in the set of models.</p

At 25°C, flies raised at normoxia performed best when tested at normoxia.

<p>The most likely probability of flight under each condition was computed by multimodel averaging. Fifty flies were tested at each concentration of oxygen.</p

All likely models included an effect of temperature on flight performance.

<p>The two most likely models also included an effect of developmental temperature. For each model, we provide the Akaike information criterion (<i>AIC</i>_<i>c</i>) and the Akaike weight, which equals the probability that the model describes the data better than other models. All models contained an intercept and an error term associated with isofemale line.</p

Flight performance depended on body temperature and oxygen supply.

<p>At 37°C (left) and 39°C (center), flies performed better if they had developed with a greater supply of oxygen. At 41°C (right), flies performed poorly overall. The color of each bar denotes the oxygen level at which flies were tested (light gray = 12%, dark gray = 21%, black = 31%). The most likely probability of flight under each condition was computed by multimodel averaging. The number of observations used to estimate the mean is marked at the top of each bar.</p
