Relationships between (A) Mass specific metabolic rate (ml O2 h-1 g-1) and ATP amount per sperm (amol cell-1), (B) mass specific metabolic rate and length-adjusted ATP concentration (amol μm-1), (C) sperm straight-line velocity (μm s-1) and ATP amount per sperm, and (D) sperm straight-line velocity and length-adjusted ATP concentration, in mammalian species. All variables are log10-transformed. R2 and p-values were estimated using phylogenetically controlled regression analyses (PGLS).
