A stochastic model for speciation by mating preferences.
TL;DR: A stochastic model of population where individuals, with type a or A, are equivalent from ecological, demographical and spatial points of view, and differ only by their mating preference, showing that mating preferences by themselves, even if they are very small, are enough to entail reproductive isolation between patches.

TL;DR: A multi-scale model to explain the evolution of microbial cooperation driving the decomposition of soil organic matter shows that the evolutionary stability of decomposition depends on a combination of local extinctions, microbial dispersal, and limited soil diffusivity.
Monte Carlo methods for linear and non-linear Poisson-Boltzmann equation
Mireille Bossy,Nicolas Champagnat,Hélène Leman,Sylvain Maire,Laurent Violeau,Mariette Yvinec +5 more
TL;DR: A new probabilistic interpretation of the nonlinear Poisson-Boltzmann PDE is proved, that also requires efficient computational geometry algorithms, and is compared with the deterministic solver APBS.
Convergence of an infinite dimensional stochastic process to a spatially structured trait substitution sequence
Hélène Leman
- 19 May 2016
TL;DR: In this article, an individual-based spatially structured population for Darwinian evolution in an asexual population is considered, where individuals move randomly on a bounded continuous space according to a reflected brownian motion.

Monte Carlo methods for linear and non-linear Poisson-Boltzmann equation
Mireille Bossy,Nicolas Champagnat,Hélène Leman,Sylvain Maire,Laurent Violeau,Mariette Yvinec +5 more
TL;DR: In this paper, the authors compare several replacement methods for the nonlinear divergence-form elliptic Poisson-Boltzmann PDE on real size biomolecules, that also require efficient computational geometry algorithms.
