  abstract = {{I}n this paper we deal with a nonlinear two-timescale discrete population model that couples age-structured demography with individual competition for resources. {I}ndividuals are divided into juvenile and adult classes, and demography is described by means of a density-dependent {L}eslie matrix. {A}dults compete to access resources; every time two adults meet, they choose either being aggressive (hawk) or non-aggressive (dove) to get the best pay-off. {I}ndividual encounters occur much more frequently than demographic events, what yields that the model takes the form of a two-timescale system. {A}pproximate aggregation methods allow us to reduce the system while preserving at the same time crucial asymptotic information for the whole population. {I}n this way, we are able to describe the total population size as function of individual aggressiveness level and environmental richness. {M}odel analysis shows a general trend with species that look for richer environment having smaller proportions of hawk individuals with larger costs.},
