哺乳动物的基础代谢率（BMR）与体重呈异速变化，但某些物种的代谢率高于或低于体重预测的原因尚不清楚。我们通过对23种哺乳动物进行比较分析，验证了寄生虫物种丰富度可能是一个促成因素的观点，这些哺乳动物的寄生虫物种丰富度、BMR、体重和两个潜在的混淆变量，即宿主密度和宿主寿命。寄生物种丰富度与BMR呈正相关，与寄主寿命负相关，与体重无关。
Basal metabolic rate (BMR) scales allometrically with body mass in mammals, but the reasons why some species have higher or lower metabolic rates than predicted from their body mass remain unclear. We tested the idea that parasite species richness may be a contributory factor by performing a comparative analysis on 23 species of mammals for which data were available on parasite species richness, BMR, body mass and two potentially confounding variables, i.e. host density and host longevity. Parasite species richness was positively correlated with BMR and negatively correlated with host longevity independent of body mass.
