Abstract

In order to mathematically model the demographic dynamics of biological populations with sexual reproduction, we consider the more realistic situation where the reproductive process occurs in a non-predictable environment. We also assume that both biological processes, mating and reproduction, are influenced by the number of couples in the population. In this framework, a class of discrete-time two-sex branching models has been introduced in (A class of two-sex branching processes with reproduction phase in a random environment. Stochastics 88:147–161) [10]. In this work, we continue the research about such a class of stochastic models, investigating the time to extinction and some applications.

This work is my modest contribution to this volume edited as a tribute to Pedro Gil. He was an excellent professional and a great person. His wise advices were very useful for me (Manuel Molina).

Notes

  1. 1.

    Given the variables X and Y, we say that X is stochastically smaller than Y if, for each real number t, \(P(X\le t)\ge P(Y\le t)\).
