In this article, we show connections among mitochondrial function, organismal metabolism, and genetic variants in long-studied garter snake populations that are either fast- (FA) or slow-aging (SA). At the cellular level, we demonstrate that Fast-aging snakes consume more oxygen relative to Slow-aging snakes; this difference becomes bigger as animals become older. Additionally, we found that genetic variation in the mitochondrial genome (cytochrome-B SNP) is associated with the fast- and slow-aging phenotypes, and the genetic variation predicts metabolic rate in a sex-specific manner.
