title: A model of age-dependent population dynamics providing simple criteria for growth or extinction.
abstract: The Gurtin-MacCamy model for age-dependent population dynamics is reduced to a single ordinary differential equation. (This is done by assuming a specific form of the mortality function, and by assuming fertility to be age-dependent only.) The model is then applied to a population of greater horseshoe bats.
