Fluctuations for fully pushed stochastic fronts
Alison Etheridge, Raphaël Forien, Thomas Hughes +1
We study the asymptotic behaviour, in the small noise limit, of stochastic travelling wave solutions to reaction-diffusion equations perturbed by Wright-Fisher noise. Such equation…

How seed banks evolve in plants: a stochastic dynamical system subject to a strong drift
Alison Etheridge, João Luiz de Oliveira Madeira
We study how changes in population size and fluctuating environmental conditions influence the establishment of seed banks in plants. Our model is a modification of the Wright-Fish…

Multi-type -coalescents from structured population models with bottlenecks
Marta Dai Pra, Alison Etheridge, Jere Koskela +1
We introduce an individual-based model for structured populations undergoing demographic bottlenecks, i.e. drastic reductions in population size that last many generations and can…
