Group (tissue-taxa combination) intercepts and slopes (including standard errors) for body mass—half-life relationships for endothermic groups.

<p>To facilitate an overall comparison among tissue-taxa combinations, the group-specific equation was used to estimate half-life (days) for a standardized 50 g animal (ln(50) = 3.91).</p><p>*Significantly different from 0 at the p<0.05 level</p><p>** Significant at the p<0.01 level</p><p>*** Significant at the p<0.0001 level</p><p>Group (tissue-taxa combination) intercepts and slopes (including standard errors) for body mass—half-life relationships for endothermic groups.</p>
