生态学的代谢理论使用新陈代谢与身体大小和温度的比例来解释物种丰度的原因和后果。然而,该理论及其实证检验从未同时检验过寄生虫和自由生活的物种。这是不幸的,因为寄生虫代表了至少一半的物种多样性。我们发现,代谢标度理论不能占丰富的寄生或自由生活的物种在三个河口食物网,直到占营养动力学。随后的分析显示,所有物种的丰度都与体重的− 3/4次方成正比。这一结果表明“生产等效性”,其中营养水平内的生物量生产在所有物种和功能组中的体型不变:无脊椎动物或脊椎动物,变温或吸热,以及自由生活或寄生。
The metabolic theory of ecology uses the scaling of metabolism with body size and temperature to explain the causes and consequences of species abundance. However, the theory and its empirical tests have never simultaneously examined parasites alongside free-living species. This is unfortunate because parasites represent at least half of species diversity. We show that metabolic scaling theory could not account for the abundance of parasitic or free-living species in three estuarine food webs until accounting for trophic dynamics. Analyses then revealed that the abundance of all species uniformly scaled with body mass to the −¾ power. This result indicates “production equivalence,” where biomass production within trophic levels is invariant of body size across all species and functional groups: invertebrate or vertebrate, ectothermic or endothermic, and free-living or parasitic.
