Sumario:This work models and analyzes the qualitative dynamics of a two-stage species with the factor of recruitment. It shows howthe dynamics is determined by a basic threshold parameter R. As a result, it is proved that if R < 1, then the extinctionequilibrium point is globally asymptotically stable, assuring that the species would disappear under this condition. Numer-ical simulations, produced by varying the parameters obtained from empirical data, show different situations regardingthe evolution of the population and allow us to validate the model
