↵a “Temperature” denotes CUE at that temperature, while “range” denotes how CUE changed over the temperature range denoted. “K” denotes Blomberg’s K, while λ denotes Pagel’s lambda. Values for which the

*P*value for a test comparing values to zero is greater than 0.05 are in gray, while the asterisks that follow values in black denote*P*< 0.05 (*),*P*< 0.01 (**), or*P*< 0.001 (***). Bullets (•) indicate*P*< 0.1. The 95% confidence intervals of K are 0.36 to 2.46, 0.32 to 2.45, 0.26 to 2.49, and 0.19 to 2.49 for a Brownian process simulated on the glucose, PDB, pyruvate, and succinate trees, respectively. The corresponding values for lambda are 0.89 to 1, 0.89 to 1, 0.9 to 1, and 0.8 to 1.
