A paradigm shift, or a paradigm adjustment? The evolution of the Oleaceae mating system as a small-scale Kuhnian case-study
A. Francq, P. Saumitou-Laprade, P. Vernet +1
Kuhn (1962) proposed an evolutionary model to explain how scientific knowledge is built, based on the concept of paradigm. Even though Kuhn's model is general, it has been applied…
Inference with selection, varying population size and evolving population structure: Application of ABC to a forward-backward coalescent process with interactions
Clotilde Lepers, Sylvain Billiard, Matthieu Porte +2
Genetic data are often used to infer demographic history and changes or detect genes under selection. Inferential methods are commonly based on models making various strong assumpt…
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 of three competing clones: Conditions and times for invasion, coexistence and fixation
Sylvain Billiard, Charline Smadi
In large clonal populations, several clones generally compete which results in complex evolutionary and ecological dynamics: experiments show successive selective sweeps of favorab…
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…
The effect of competition and horizontal trait inheritance on invasion, fixation and polymorphism
Sylvain Billiard, Pierre Collet, Régis Ferrière +2
Horizontal transfer (HT) of heritable information or `traits' (carried by genetic elements, endosymbionts, or culture) is widespread among living organisms. Yet current ecological…
A general stochastic model for sporophytic self-incompatibility
Sylvain Billiard, Viet Chi Tran
Disentangling the processes leading populations to extinction is a major topic in ecology and conservation biology. The difficulty to find a mate in many species is one of these pr…
