Resumen:
We review a two-sex population model and focus on the link between demography and social structure in a polygynous species. The model was applied to the southern elephant seal population of Península Valdés, one that shows contrasting trends in two demographic subunits with distinct social structure. This apporach provides a general framework to include social variables into population dynamics. This perspective extends the scope of standard lineal models and adds a tool that identifies the relative effect of changes in number of one sex on the population.
