A time discrete linear model of an age and time of residence structured population in a patchy environment Moussaoui A. auteur aut IRD Auger Pierre auteur aut IRD Khaladi M. auteur aut IRD Ghouali N. auteur aut IRD text journalArticle eng We present a multiregional Leslie matrix population model for an age-structured population in a heterogeneous environment of patches connected by migrations. The aim of the model is to take into account the time of residence of individuals in the patches. We present an application of the model in ecotoxicology. We consider a population located on two patches with a polluted patch whereas the other one is unpolluted. We study the effects of pollutant concentration and of the time of residence in the polluted patch on the global population growth rate. The model could be generalized to the case of N patches (N > 2) for Salmo trutta and cadmium concentration. specialized 080 020 South African Journal of Science 104 5-6 203-208 2008 0038-2353 https://www.documentation.ird.fr/hor/PAR00002750 0038-2353 https://www.documentation.ird.fr/hor/PAR00002750 IRD - Base Horizon / Pleins textes 2008-11-07 2017-08-23 PAR00002750 fre
