The gut microbiota features important genetic diversity, and the specific spatial features of the gut may shape evolution within this environment. We investigate the fixation probability of neutral bacterial mutants within a minimal model of the gut that i ...
The study of insular populations was key in the development of evolutionary theory. The successful colonisation of an island depends on the geographic context, and specific characteristics of the organism and the island, but also on stochastic processes. A ...
À travers l’habitat et le questionnement de notre quotidien, le Fémilistère réunit les idéaux féministes soutenant une architecture inclusive, la collectivisation des tâches domestiques et du « care » dans un habitat communautaire, inspiré du Familistère. ...
S’il est un modèle d’habitat associé aux périphéries urbaines, c’est bien celui de la maison individuelle. Intimement liée à l’essor de la mobilité automobile, la propagation de ce type d’habitation dans les campagnes entourant les villes fait partie inté ...

L'exploration humaine de l'espace n'en est qu'à ses débuts, et depuis le premier vol de Gagarine en 1961, le temps de vol des astronautes n’a cessé d’augmenter. Depuis le début des années 2000, une nouvelle ère s'est ouverte avec l'arrivée d'entreprises pr ...
Human activities are resulting in many land-use changes, particularly due to urbanisation and intensification of agricultural practices. Because of these changes, in addition to climate change, many species are facing habitat degradation. In order to avoid ...
We investigate the evolutionary rescue of a microbial population in a gradually deteriorating environment, through a combination of analytical calculations and stochastic simulations. We consider a population destined for extinction in the absence of mutan ...
Owing to stochastic fluctuations arising from finite population size, known as genetic drift, the ability of a population to explore a rugged fitness landscape depends on its size. In the weak mutation regime, while the mean steady-state fitness increases ...
Does the scaling relationship between population sizes of cities with urban metrics like economic output and infrastructure (transversal scaling) mirror the evolution of individual cities in time (longitudinal scaling)? The answer to this question has impo ...
C’est comme un rituel: le printemps sonne le retour d’une pratique dont seuls les Russes ont le secret, celle de (re)vivre à la datcha. Ayant séduit les citadins depuis près de deux siècles, la datcha offre le lopin de terre qu’il est possible de personnal ...
