How to live in the city when you are an ant? (Live City of Paris)

As part of a partnership with the City of Paris, several members of the laboratory (Basile Finand, Céline Bocquet, Pierre Federici, Thibaud Monnin et Nicolas Loeuille (“EERI” Team of “DCFE” Department and “ESEAE” Team of “EcoEvo” Department) sample the soil fauna and in particular the ants in the Parisian green spaces. To popularize and explain this […]

A stressful life in the city affects birds’ genes

Great tits living in cities are genetically different from great tits in the countryside. This is what researchers have found in a unique study, where they examined populations of great tits in nine large European cities.

The researchers compared the city bird genes with the genes of their relatives in the countryside. It did not matter if the great tits lived in Milan, Malmö or Madrid: in order to handle an environment created by humans, the birds evolved in a similar way.

Team Phenotypic variability and adaptation “VPA”

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. […]

Worker size diversity does not improve colony success in the ant Temnothorax nylanderi

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 […]

Social Species in their Environments : Adaptation and Evolution “ESEAE” Team

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 […]

Evolutionary Ecophysiology “EPE” Team

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 […]
