Talk 1 : Amandine Veber (Université Paris Cité)

Title : Modelling the evolution of genetic diversity in a population living in a spatial continuum

Abstract : The spatial structure of a population influences the way genes are transmitted from one generation to the next, and consequently how the genetic diversity in the population evolves through time. To model this evolution when the population lives in continuous space (a forest, a mountain range, ...), a stochastic process called the spatial Lambda-Fleming-Viot process was introduced in 2008 by Alison Etheridge (Oxford Univ.) and Nick Barton (IST Austria), and has been developed in a various directions since then. We shall review some of the results obtained thanks to this approach, and related questions that are still open.

Talk 2 : Apolline Louvet (University of Bath)

Title : Constructing a stochastic population genetics process for populations expanding in a spatial continuum

Abstract : Spatial Lambda-Fleming Viot processes, or SLFVs, are a family of models for the evolution of genetic diversity in populations living in a spatial continuum. Their main characteristics is their "event-based" reproduction dynamics and the assumption that the area occupied is constant over time. In this talk, I will show how the SLFV modelling framework can be extended to include spatially expanding populations. In order to do so, I will introduce one possible approach to construct SLFVs formally, which is a variant of the method introduced in 2015 by Amandine Véber (Univ. Paris Cité) and Anton Wakolbinger (GU Frankfurt). This approach makes it possible to couple SLFV processes and explore new limiting regimes.
