DESCRIPTION:Speakers: Laetitia Colombani (ISFA\, Lyon)\n\nIn the last deca
 des\, environmental changes and the consequences of the evolution of the p
 opulation\, especially the phenotypic evolution\, have been described by d
 ifferent models. In this ongoing study\, with Tran and Méléard\, we aim 
 to understand the individual dynamics of a population. In particular\, we 
 want to describe the ancestral lineage of a living individual. Some prelim
 inary work has been published by Calvez\, Henry\, Méléard and Tran in 20
 22 when the initial population is well distributed and is close to the sta
 tionary solution of a PDE.In this talk\, I will introduce the model\, its 
 construction\, and the link with the PDE of the macroscopic dynamics of th
 e phenotypic density. I'll then describe some of the results we obtain whe
 n we consider any initial repartition of the population.\n \n\nhttps://in
