Ecological scaling

Ecological scaling refers to the application of allometric scaling principles to ecological systems, describing how population dynamics, species interactions, and ecosystem properties change with body size, abundance, or spatial scale. The metabolic theory of ecology, for instance, uses metabolic scaling to predict population growth rates, carrying capacities, and interaction strengths from the body size and metabolic rates of constituent species.

Ecological scaling reveals that ecosystems are not arbitrary collections of species but structured by scaling constraints that link individual physiology to community organization. The scaling of predator-prey body size ratios, the allometry of home range size, and the species-area relationship all suggest that ecological communities are shaped by the same network-physics constraints that govern biological organisms.
