Abstract

We give formulas for the computation of the age-class-specific fecundities Fn and survival probabilities Pn of the Leslie matrix. These formulas are intended primarily for use with populations such as insects in which survivorship depends on life stage but is independent of age within a given state. The Leslie matrix elements are computed by subdividing each age class into a collection of subclasses and then allowing the number of subclasses to tend to infinity. The matrix elements computed in this way provide a relatively accurate representation of the dynamics of the population even when only a few age classes are used to subdivide the population.
