Team members Publications Our research aims to understand the ecological and evolutionary causes of phenotypic variability. We investigate the consequences of this variability for demographic processes which depend on environmental conditions. We use different research models to address major topics (the common lizard, annual killifish, springtails), in the lab, in mesocosms and in the field. […]

“Here, we used 37 years of mark-recapture data in two nearby habitats inside a meadow viper Vipera ursinii population to quantify life expectancies, generation times and the shape of actuarial and reproductive senescence.”

Social groups consist of individuals that differ from one another, and many studies show that this diversity improves group efficiency. In social insects, size diversity can, for example, improve the efficiency of foraging, nest building, brood rearing and production of young queens. Thus, colonies that re more diverse are generally also more efficient. Romain Honorio […]

Team publications Team members The aim of the ESEAE team is to understand how social life influences the mechanisms of evolution and adaptation of social species, their biodiversity, and their interactions with other species. Environmental changes are a central theme. Our biological models are mainly termites and ants. We use an integrative approach that focuses […]

Team publications Team members Studies in evolutionary ecology aims to understand how biological traits are controlled by natural and sexual selection. These studies examine how environmental selection pressures influence one hand the production and survival of young and secondly the dynamics of populations and ecosystems. These studies often ignore the physiological mechanisms involved in developmental processes […]

Teams of department Publications of department Members of department The three research teams of the Department of Evolutionary ecology study the ecological and evolutionary causes and consequences of individual phenotypic variability. Studies focus on behaviour, physiology, morphology, and life history traits. The teams undertake experimental and theoretical studies using a variety of animal models (birds, […]

City life could lead to differential evolution between urban and forest populations. Aurelie Khimoun and her collaborators showed, in their article published in Biology Letters, that urban populations of the tiny acorn ant are surprisingly not genetically differentiated from forest populations, suggesting expansion and lack of isolation. However, some genes display traces of selection that point towards an adaptation to the urban environment.
