Critical times (Tcrit) and critical energetic thresholds (ycrit).

These were determined from linear regressions between percent dry mass and time of mortality or LOE endpoint that statistically showed a zero slope (ncrit sample size; thick black lines in Fig 2). Tcrit represents the time when heat stress switches to starvation stress, and ycrit, represents the critical energetic thresholds in percent dry mass estimated as intercepts only. Values in parentheses represent 95% confidence intervals. N is the total number of individuals tested in the challenge experiment and measured for percent dry mass.
