title: Sizing up size ratios.
abstract: The investigation of the causes of observed size differences between coexisting related animal species requires a knowledge of the statistical distributions of size ratios in randomly constructed guilds. Null models can be useful, but are often subject to constraints that severely limit their applicability. New work on the statistics of size distributions may lead to a better understanding of why animals are the sizes they are.
