In 1945 the British ecologist P.H. Leslie analyzed a matrix model for an age-structured population of rodents, thus adapting Lotka’s work to a discrete-time framework. He emphasized that the growth rate corresponds to an eigenvalue and the “stable” age structure to an eigenvector. He also estimated numerically the “net reproduction rate” R 0 for the brown rat.
