Surface areas and volumes of biological systems—from molecules to organelles, cells, and organisms—affect their biological rates and kinetics. Therefore, surface area–to-volume ratios and the scaling of surface area with volume profoundly influence ecology, physiology, and evolution. The zeroth-order geometric expectation is that surface area scales with body mass or volume as a power law with an exponent of two-thirds, with consequences for surface area–to-volume (SA∶V) ratios and constraints… Expand

TLDR
Allometric shape patterns are an important correlate of the capacity of individual populations to compensate for increases in their cell volumes by increasing the surface area, however, variation in allometric patterns was not associated with phylogenetic structure, indicating that the position of the populations in the allometric space was not evolutionarily conserved and might be influenced by environmental factors. Expand
The principles of cellular geometry scaling.
TLDR
How cells interpret their size, buffer against changes in shape and, if necessary, scale their polarity to maintain optimal shape at different cell volumes is discussed. Expand
Heterogeneity of cells may explain allometric scaling of metabolic rate
TLDR
A simple geometry model is proposed that shows that a hypothesis that total surface area of cells determines metabolic rate can reproduce these two observations by combining two concepts: the impact of cell sizes on metabolic rate and fractal-like (hierarchical) organization. Expand
Metabolic Scaling in Complex Living Systems
TLDR
This heuristic attempt at building a unifying theory of metabolic scaling will not only stimulate further testing of all of the various subtheories composing it, but also foster an appreciation that many current models are, at least in part, complementary or even synergistic, rather than antagonistic. Expand
Major evolutionary transitions of life, metabolic scaling and the number and size of mitochondria and chloroplasts
TLDR
The results suggest that endosymbiosis fundamentally altered the metabolic scaling of free-living bacterial ancestors of mitochondria and chloroplasts, from steep ancestral scaling to a shallower scaling in their endosYmbiotic descendants. Expand
Shape shifting predicts ontogenetic changes in metabolic scaling in diverse aquatic invertebrates
TLDR
It is shown that in diverse aquatic invertebrates, ontogenetic shifts in the scaling of routine metabolic rate are associated with significant changes in body shape and the observed inverse correlations between bR and bL are predicted by metabolic scaling theory that emphasize resource/waste fluxes across external body surfaces, but contradict theory that emphasizes resource transport through internal networks. Expand
Respiration in heterotrophic unicellular eukaryotic organisms.
TLDR
The results predict that for small and medium sized protozoa maximum respiration rates should be proportional to cell volume and access to intracellular O2 is not limiting except at very low ambient O2-tensions and for large cell size. Expand
Body shape shifting during growth permits tests that distinguish between competing geometric theories of metabolic scaling.
TLDR
Metabolic scaling slopes of diverse integument-breathing species were significantly positively correlated with degree of body flattening or elongation during ontogeny, as expected from surface area theory, but contradicting the negative correlations predicted by resource-transport network models. Expand
Are the surface areas of the gills and body involved with changing metabolic scaling with temperature?
TLDR
In the goldfish, temperature positively affects metabolic level but negatively affects the scaling exponent of resting metabolic rate, supporting the metabolic-level boundaries hypothesis. Expand
Ecological pressures and the contrasting scaling of metabolism and body shape in coexisting taxa: cephalopods versus teleost fish
TLDR
It is suggested that differences in lifestyle, growth and body shape with changing water depth may be useful for predicting contrasting metabolic scaling for coexisting animals of similar sizes. Expand

TLDR
If the criteria for a strict description of natural fractals are met, then it follows that a Fractal Geometry of Life may be envisaged and all natural objects and biological systems exhibiting self-similar patterns and scaling properties may be considered as belonging to the new subdiscipline of "fractalomics".
