Beyond the '3/4-power law': Variation in the intra- and interspecific scaling of metabolic rate in animals
TL;DR
Metabolic scaling exponents range from 0.65 to 0.85 across groups
Critical review noting variation in metabolic scaling exponents (0.65-0.85) across taxonomic groups, challenging the universality of precise 3/4 scaling. Important for understanding that while scaling patterns exist, precise exponents vary by context - just as organizational scaling varies by industry and structure.
Key Findings from Glazier (2005)
- Metabolic scaling exponents range from 0.65 to 0.85 across groups
- Temperature, activity level, and phylogeny cause variation
- 3/4 may be an average rather than a universal constant
