“…In addition, the hypometric scaling of metabolic rate ( b < 1) among carabid beetles species appears to be related to larger species having larger cells in their ommatidia and Malphigian tubules than do smaller species [ 41 ]. Finally, although not previously recognized, the frequent observation of hypermetric scaling of metabolic rate ( b > 1) in embryos and initial postembryonic stages of various kinds of animals and plants [ 9 , 14 , 90 , 91 , 92 , 93 , 94 , 95 , 96 , 97 , 98 , 99 ] is consistent with cell-size metabolic scaling theory, because embryonic and initial postembryonic development often involves prolific cell multiplication with relatively little or no gain in biomass [ 100 , 101 ], thus generating smaller cells with greater total SA per embryo V that can support a higher R / M (see Figure 2 ).…”

“…Many kinds of organisms show ontogenetic shifts in metabolic scaling (e.g., [ 9 , 72 , 91 , 93 , 95 , 97 , 98 , 99 , 102 , 103 , 104 , 105 , 106 , 107 ]). Most of these shifts involve relatively steep metabolic scaling during early postembryonic development and shallower scaling during later development (i.e., the Type III metabolic scaling described in [ 9 ]).…”

How Metabolic Rate Relates to Cell Size

Metabolic rate and its covariation with body mass vary substantially within and among species in little understood ways. Here, I critically review explanations (and supporting data) concerning how cell size and number and their establishment by cell expansion and multiplication may affect metabolic rate and its scaling with body mass. Cell size and growth may affect size-specific metabolic rate, as well as the vertical elevation (metabolic level) and slope (exponent) of metabolic scaling relationships. Mechanistic causes of negative correlations between cell size and metabolic rate may involve reduced resource supply and/or demand in larger cells, related to decreased surface area per volume, larger intracellular resource-transport distances, lower metabolic costs of ionic regulation, slower cell multiplication and somatic growth, and larger intracellular deposits of metabolically inert materials in some tissues. A cell-size perspective helps to explain some (but not all) variation in metabolic rate and its body-mass scaling and thus should be included in any multi-mechanistic theory attempting to explain the full diversity of metabolic scaling. A cell-size approach may also help conceptually integrate studies of the biological regulation of cellular growth and metabolism with those concerning major transitions in ontogenetic development and associated shifts in metabolic scaling.

Metabolism energizes all biological processes, and its tempo may importantly influence the ecological success and evolutionary fitness of organisms. Therefore, understanding the broad variation in metabolic rate that exists across the living world is a fundamental challenge in biology. To further the development of a more reliable and holistic picture of the causes of this variation, we review several examples of how various intrinsic (biological) and extrinsic (environmental) factors (including body size, cell size, activity level, temperature, predation and other diverse genetic, cellular, morphological, physiological, behavioural and ecological influences) can interactively affect metabolic rate in synergistic or antagonistic ways. Most of the interactive effects that have been documented involve body size, temperature or both, but future research may reveal additional ‘hub factors’. Our review highlights the complex, intimate inter-relationships between physiology and ecology, knowledge of which can shed light on various problems in both disciplines, including variation in physiological adaptations, life histories, ecological niches and various organism-environment interactions in ecosystems. We also discuss theoretical and practical implications of interactive effects on metabolic rate and provide suggestions for future research, including holistic system analyses at various hierarchical levels of organization that focus on interactive proximate (functional) and ultimate (evolutionary) causal networks. This article is part of the theme issue ‘The evolutionary significance of variation in metabolic rates’.
