Human population size is constrained by body mass and metabolic needs
Multiple studies support the principle that organismal body mass and metabolic requirements impose fundamental constraints on population density, geographic range size, and ecological scaling.
The claim posits that human (or animal) population size and dynamics are constrained by body mass and metabolic needs. While papers [0], [1], [4], and [8] discuss metabolic scaling and allometry broadly, papers [6], [7], and [9] explicitly link metabolic constraints and body mass directly to population abundance, range limits, and ecological distribution. No papers refute the core premise that metabolism and body mass constrain population-level ecological parameters.

Demonstrates that organismal energetic characteristics, metabolic rates, and body mass directly shape ecological processes and limit species geographic range sizes.

Combines generalized extreme value theory with the resource-limited metabolic restriction hypothesis to show that population abundance and size scaling are constrained by metabolic demands.

Supports the resource-limited metabolic restriction hypothesis showing that population abundance scaling and maxima are constrained by organismal metabolic needs and body size.
