“…As expected from predictions of cell SA theory, multiple studies have reported negative associations between R / M and cell size (or its proxy, genome size) among related animal species, including carabid beetles [ 41 ], amphibians [ 22 , 28 , 54 ], eyelid geckos [ 32 ], birds [ 28 , 40 , 55 ], and mammals [ 26 ] (for recent reviews, see [ 20 , 56 , 57 ]). Most of these studies have focused on the sizes of erythrocytes (red blood cells), which are importantly involved in oxygen exchange in respiratory systems and thus may be linked to R / M for this reason.…”

“…Most of these studies have focused on the sizes of erythrocytes (red blood cells), which are importantly involved in oxygen exchange in respiratory systems and thus may be linked to R / M for this reason. However, associations between R / M and other types of non-respiratory cells (e.g., in ommatidia and Malphigian tubules of carabid beetles [ 41 ]) have also been found, and thus cell size may have a general effect on organismal metabolic rate, which requires further research (see also Section 2.1.3 , Section 2.2 , Section 2.3 , and Section 3 ).…”

“…Many kinds of theories and hypotheses have been proposed, but no consensus has yet been reached, especially with respect to the causes of the body-mass scaling of metabolic rate (see e.g., [ 8 , 9 , 10 , 13 , 14 , 15 , 17 , 18 , 20 ]). Of these causes, growing interest has been shown regarding how various components of body size in multicellular organisms, such as cell size [ 9 , 14 , 18 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 ] and organ size [ 9 , 14 , 17 , 18 , 20 , 34 , 43 , 44 , 45 , 46 , 47 , 48 , 49 ], may influence variation in metabolic rate and its scaling with body mass. Since cells are where metabolism happens, it seems natural to explore how the properties of cells may affect metabolism at the tissue, organ, and whole-body levels.…”

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.

“…The VO 2 of an organism is generally accepted to show negative allometry, scaling to body mass, because the scaling exponent is less than unity. Thus, the mass-specific rate of metabolism (VO 2 /M) should decrease as an organism's body mass increases [9][10][11][12][13][14][15][16][17][18]. For decades, however, predictions of scaling exponent values have been continually challenged, and this remains a highly debated topic in physiology and ecology [6,[19][20][21][22][23][24][25][26][27][28][29][30].…”

Ontogeny of the Respiratory Area in Relation to Body Mass with Reference to Resting Metabolism in the Japanese Flounder, Paralichthys olivaceus (Temminck & Schlegel, 1846)

Metabolism is the fundamental process dictating material and energy fluxes through organisms. Several studies have suggested that resting metabolic scaling in various aquatic invertebrates is positively correlated with changes in body shape and the scaling of body surface area, which agrees with the surface area theory, but contradicts the negative correlations predicted by the resource–transport network theory. However, the relationship between resting metabolic scaling and respiration area, particularly in asymmetric fish that have undergone dramatically rapid metamorphosis, remains unclear. In this morphometric study in an asymmetric fish species (Paralichthys olivaceus), I compared my results with previous reports on resting metabolic scaling. I measured the respiratory area of P. olivaceus specimens aged 11–94 days (body weight, 0.00095–1.30000 g, respectively) to determine whether and how the resting metabolic scaling is associated with changes in body shape and respiratory area. Resting metabolic scaling might be more closely related to body surface area, because their slopes exactly corresponded with each other, than to respiratory area. Furthermore, confirming the surface area theory, it was linked to changes in body shape, but not from the resource–transport network theory. These findings provide new insights into the scaling mechanisms of area in relation to metabolism in asymmetric fish.

“…Many of these hypothetical suborganismal mechanisms involve body-size-related changes in the surface area or composition of cellular or subcellular membranes and (or) rates of flow of protons, ions, nutrients and metabolic wastes across them or within subcellular networks. For example, different cellular modes of organismal growth, involving increasing cell size or number or both, determine the total amount of cellular surface area available for uptake of resources and release of metabolic wastes in organisms of different size, with potential consequences for whole-organism metabolic scaling (Davison, 1955;Kozłowski et al, 2003Kozłowski et al, , 2020Schramm et al, 2021).…”

Widely observed allometric scaling (log–log slope<1) of metabolic rate (MR) with body mass (BM) in animals has been frequently explained using functional mechanisms, but rarely studied from the perspective of multivariate quantitative genetics. This is unfortunate, given that the additive genetic slope (bA) of the MR–BM relationship represents the orientation of the ‘line of least genetic resistance’ along which MR and BM may most likely evolve. Here, we calculated bA in eight species. Although most bA values were within the range of metabolic scaling exponents reported in the literature, uncertainty of each bA estimate was large (only one bA was significantly lower than 3/4 and none were significantly different from 2/3). Overall, the weighted average for bA (0.667±0.098 95% CI) is consistent with the frequent observation that metabolic scaling exponents are negatively allometric in animals (b<1). Although bA was significantly positively correlated with the phenotypic scaling exponent (bP) across the sampled species, bP was usually lower than bA, as reflected in a (non-significantly) lower weighted average for bP (0.596±0.100). This apparent discrepancy between bA and bP resulted from relatively shallow MR–BM scaling of the residuals [weighted average residual scaling exponent (be)=0.503±0.128], suggesting regression dilution (owing to measurement error and within-individual variance) causing a downward bias in bP. Our study shows how the quantification of the genetic scaling exponent informs us about potential constraints on the correlated evolution of MR and BM, and by doing so has the potential to bridge the gap between micro- and macro-evolutionary studies of scaling allometry.
