Make love and war – Quantifying discrete male polymorphic reproductive ratios

Abstract
Fighters primarily develop at low population densities; Though the

Data is presented to illuminate these matters and a model is developed linking fighter development to the costs of being a fighter (in terms of survival) and the benefits of being a fighter (in terms of fecundity).
