An individual-based stochastic model reveals strong constraints on allometric relationships with minimal metabolic and ecological assumptions
Sylvain Billiard, Virgile Brodu, Nicolas Champagnat +1
We design a stochastic individual-based model structured in energy, for single species consuming an external resource, where populations are characterized by a typical energy at bi…
Convergence of knowledge in a cultural evolution model with population structure, random social learning and credibility biases
Sylvain Billiard, Maxime Derex, Ludovic Maisonneuve +1
Understanding how knowledge is created and propagates within groups is crucial to explain how human populations have evolved through time. Anthropologists have relied on different…
Identifying conversion efficiency as a key mechanism underlying food webs evolution : a step forward, or backward ?
Coralie Fritsch, Sylvain Billiard, Nicolas Champagnat
Body size or mass is one of the main factors underlying food webs structure. A large number of evolutionary models have shown that indeed, the adaptive evolution of body size (or m…
Rejuvenating functional responses with renewal theory
S. Billiard, V. Bansaye, J. -R. Chazottes
Functional responses are widely used to describe interactions and resources exchange between individuals in ecology. The form given to functional responses dramatically affects the…
Stochastic dynamics for adaptation and evolution of microorganisms
Sylvain Billiard, Pierre Collet, Régis Ferrière +2
We present a model for the dynamics of a population of bacteria with a continuum of traits, who compete for resources and exchange horizontally (transfer) an otherwise vertically i…
Perennial life-histories and demographic advantages may play contradictory roles in the evolution of plant mating systems
Diala Abu Awad, Viet-Chi Tran, Sylvain Billiard
When predicting the fate and consequences of recurring deleterious mutations in self-fertilising populations most models developed make the assumption that populations have discret…
