We construct a measure-valued equivalent to the spatial Lambda-Fleming-Viot process (SLFV) introduced in [Eth08]. In contrast with the construction carried out in [Eth08], we fix the realization of the sequence of reproduction events and obtain a quenched evolution of the local genetic diversities. To this end, we use a particle representation which highlights the role of the genealogies in the attribution of types (or alleles) to the individuals of the population. This construction also…

The k-parent spatial Lambda-Fleming-Viot process as a stochastic measure-valued model for an expanding population
An alternative construction of the k-parent SLFV is introduced, adapted from [38], which allows us to couple SLFVs with different selection strengths and is reminiscent of the Eden growth model, but with an associated dual process of potential ancestors, making it possible to investigate the genetic diversity in a population sample.
Pathwise construction of tree-valued Fleming-Viot processes
In a random complete and separable metric space that we call the lookdown space, we encode the genealogical distances between all individuals ever alive in a lookdown model with simultaneous multiple
The spatial Lambda-Fleming-Viot process with fluctuating selection
We are interested in populations in which the fitness of different genetic types fluctuates in time and space, driven by temporal and spatial fluctuations in the environment. For simplicity, our
Stochastic measure-valued models for populations expanding in a continuum
We model spatially expanding populations by means of two spatial Λ-Fleming Viot processes (or SLFVs) with selection: the k -parent SLFV and the ∞ -parent SLFV. In order to do so, we fill empty areas
Branching Brownian motion and Selection in the Spatial Lambda-Fleming-Viot Process
We ask the question "when will natural selection on a gene in a spatially structured population cause a detectable trace in the patterns of genetic variation observed in the contemporary
A central limit theorem for the spatial Lambda Fleming-Viot process with selection
We study the evolution of gene frequencies in a population living in $\mathbb{R}^d$, modelled by the spatial Lambda Fleming-Viot process with natural selection (Barton, Etheridge and Veber, 2010 and
Rate of coalescence of pairs of lineages in the spatial {\lambda}-Fleming-Viot process
This work revisits the spatial λ-Fleming-Viot process and addresses the question of whether the genealogical process of the model "comes down from infinity", which has been partly answered before.
The Brownian Net and Selection in the Spatial Lambda-Fleming-Viot Process
We obtain the Brownian net of Sun and Swart (2008) as the scaling limit of the paths traced out by a system of continuous (one-dimensional) space and time branching and coalescing random walks. This
Genealogical constructions of population models
Representations of population models in terms of countable systems of particles are constructed, in which each particle has a `type', typically recording both spatial position and genetic type, and a
Rescaling the spatial Lambda-Fleming-Viot process and convergence to super-Brownian motion
We show that a space-time rescaling of the spatial Lamba-Fleming-Viot process of Barton and Etheridge converges to super-Brownian motion. This can be viewed as an extension of a result of


We extend the spatial -Fleming–Viot process introduced in [Electron. J. Probab. 15 (2010) 162–216] to incorporate recombination. The process models allele frequencies in a population which is
The spatial $\Lambda$-Fleming–Viot process on a large torus: Genealogies in the presence of recombination
We extend the spatial $\Lambda$-Fleming-Viot process introduced in [Electron. J. Probab. 15 (2010) 162-216] to incorporate recombination. The process models allele frequencies in a population which
A modified lookdown construction for the Xi-Fleming-Viot process with mutation and populations with recurrent bottlenecks
Letbe a finite measure on the unit interval. A �-Fleming-Viot process is a probability measure valued Markov process which is dual to a coalescent with multiple collisions (�-coalescent) in analogy
Large scale behaviour of the spatial $\varLambda $-Fleming–Viot process
We consider the spatial �-Fleming-Viot process model ([BEV10]) for frequencies of genetic types in a population living in R d , in the special case in which there are just two types of individual,
A countable representation of the Fleming-Viot measure-valued diffusion
The Fleming-Viot measure-valued diffusion arises as the infinite population limit of various discrete genetic models with general type space. The paper gives a countable construction of the process
A New Model for Evolution in a Spatial Continuum
We investigate a new model for populations evolving in a spatial continuum. This model can be thought of as a spatial version of the Lambda-Fleming-Viot process. It explicitly incorporates both small
Stochastic flows associated to coalescent processes
Abstract. We study a class of stochastic flows connected to the coalescent processes that have been studied recently by Möhle, Pitman, Sagitov and Schweinsberg in connection with asymptotic models
Phase transitions in a spatial coalescent
We construct a natural extension of the Lambda-coalescent to a spatial continuum, and analyse its behaviour. Like the Lambda-coalescent, the individuals in our model can be separated into (i) a dust
