Abstract

It is argued that birth rate, turnover rate and production/biomass ratios (P/B) are equivalent in stable populations. It is then shown from field data on 21 mammal species that production scales as a 2/3 power of body mass, suggesting that size rather than life history characteristics explain most interspecific variation. The relationship simolifies calculations of annual production in populations and energy flow through communities.
