a Mitochondrial H₂O₂ production during succinate respiration, including analysis of residual values after correcting for body mass. b ln maximum lifespan vs ln body mass; c ln H₂O₂ production; d residual values for ln maximum lifespan vs residuals for ln rate of H₂O₂ production after correcting for body mass. The correlation in a is significant (r² = 0.54, F_1,10 = 11.7, P = 0.007); the correlation in d is significant (r² = 0.69, F_1,10 = 22.5, P = 0.0008). Upper case letters denote data for the following species or strains: A mouse; Mus musculus (C57BL/6, BALB/c, and wild Idaho strains); B rat, Rattus norvegicus; C white-footed mouse, Peromyscus leucopus; D naked mole-rat, Hetereocephalus glaber; E Damara mole-rat, Cryptomys dearness; F guinea pig, Cavia porcellus; G baboon, Papio cynocephalus; H Brazilian free-tailed bat, Tadarida brasiliensis; I little brown bat, Myotis lucifugus; J domestic ox, Bos taurus; K Japanese quail, Coturnix japonica; L domestic pigeon Columba livia.
